IT HAS BEEN almost five years since I first began my study of dementia after my mother passed away from the effects of dementia and what was probably the beginning stages of true Alzheimer’s. I wanted to know its causes as well as what is being done to find a cure. Though I have found answers to my many questions, it still holds my interest and continues to be a major concern of mine.

When I first began my quest, my focus was on my parents’ generation and the toll it was taking on them, but I am now starting to see the advent of dementia and Alzheimer’s in my generation. Two acquaintances of mine appear to be in the beginning stages and a close relative has died from Lewy Body disease. This is why I believe it crucial that we stay informed about it even if it does not directly affect our immediate families. It is, and will be, until a cure is found, society’s problem. As more of our population moves into their elderly years, solutions must be found to help them. These involve not only problems with insurance and the high cost of drugs, but with safe housing and need for more caregivers that are paid a decent wage.

I have studied many scientific books and articles in my search over the years, but have found the internet to be a key source of information; in fact it is probably better able to offer the latest findings about dementia from scientific studies or advice from experts on caregiving. After years spent searching and reading through innumerable sites, I have come to rely on several that offer reliable, professional, scientifically based facts or guidance. Rather than my trying to keep you up-to-date on the latest research or finding articles that address problems a caregiver of a dementia or Alzheimer’s patient may have, I will share these sites with you in hopes that you  save them as a Bookmark or Favorite and go back to them if you want to find the latest research news or have a caregiver question.

nia.nih.gov   National Institute on aging/National Institute on Health is a a governmental agency under the Department of Health and Welfare. There are 31 funded laboratories around the country studying the problems associated with aging, most at Medical schools or Universities. (The knowledge that so many institutions and dedicated individuals are working on this is heartening.) They also have a wealth of information on caregiving.

alz.org  The Alzheimer’s Association is a good resource for information on support groups. They also offer research and caregiver guidance.

aarp.org American Association of Retired Persons is an excellent source for help with decisions that need to be made like what to look for in a caregiving facility or home,  weighing in-home care with  placement in a facility, finding an elder law attorney, etc. It also gives support and advice for caregivers.

agingcare.com is a private site but has articles on caregiver topics as well as a forum where questions can be answered by others who have had similar experiences. 

And don’t forget the two downloadable booklets I have listed under the Resources tab at the top of the page!

Of Interest: Researchers at the University of California Davis and San Francisco have developed a program using a computer with the ability to learn and improve, known as machine learning, that can help analyze amyloid plaques in human brain tissue. This technique automates the process of measuring plaques and their different characteristics which, inevitably could enable larger-scale analysis of brain tissue to help accelerate research on the possible causes of Alzheimer’s and how the disease progresses. I’m sure we will see more instances of the pairing of science and the learning computer in the coming years. 

Preparation for Eldercare

What would you do if your parent became incapacitated and/or was unable to make decisions on their own?

We don’t like to think about the time our parents will no longer be with us and we will need to handle their affairs. However, as people continue to live longer the need to first help an aging parent is a more likely scenario.

Here is the hard part and one which most of us put off: Having a frank discussion about the future with your parent. Talking about it may sound callous or uncaring, but preparing for the eventuality is actually quite the opposite. If you explain to them that they would be helping you they’d feel they were still in control and be more amenable to sharing. They should realize working with you and getting all their legal information together now will make it easier when the time comes when they need your help.

This advice I am giving is through hindsight. I did not sit down with my mother and discuss the possibility of the need for me to make decisions on her behalf. Once Mom began having memory problems I gradually began making many decisions for her. Would it have been easier if we had discussed it before-hand? I don’t know. She still might have resisted but been in a more reasonable state of mind.

I encountered a few problems trying to help my mother during her dementia, which I will share, then I will give my recommendations based on what I learned along the way.

What I did do that made the transition less complicated was that I already had Power of Attorney. A few years before, after my father died, I took Mom  to her attorney and she had a new will written and a trust  created  which named me as a trustee and gave me POA.

A major symptom of dementia is difficulty working with numbers. So it became for my mother. The first task I had to undertake was paying her bills. It did require some convincing, but she eventually realized she needed help.

What did not go as smoothly was when tried to have my mother’s funds consolidated and moved to one bank. It made more sense to combine her savings and there was no need for two checking accounts. At the bank we were shown to the desk of a customer service representative where I explained that we wanted to close my mother’s account, whereupon the representative looked at my mother and asked “Is this what you want to do?”  Even though I had already explained the justification to her and thought she understood, Mom answered, “No.” It took several times of my trying to reason with my mother and her saying, “No.” to ultimately convince her. I can understand the bank was trying to protect her, not knowing if I were trying to coerce her into giving me her money. I also encountered this privacy problem many times over the phone talking to different agencies; they always wanted to obtain permission from Mom first and it was hard for them to understand it would be confusing for her.

One of the more important documents I regret not having is the directive for access to her health information. When my mother was given several tests after I had taken her to the emergency room, I went to the hospital the next day to find out the results. I was denied. What I needed was a paper signed by my mother giving me permission to see her health information and/or speak with her doctors. Another option I could have used was to be appointed to be her health proxy which is a more formal authorization and requires notarization. At this time, my mother was often defensive and contrary, and the chance of getting her to sign such a paper were slim. 

Another advantage I had in overseeing my mother’s legal effects is that she was very organized, as was my father, who left written notes for my mother, so all of their legal documents and papers were easily accessible. I can imagine how difficult it could be if a parent was both disorganized and confused.

Essential Documents Needed for Eldercare

       A will and trust listing who will be acting trustee(s) in their stead 

      Power of Attorney to make financial decisions 

       A list of all bank accounts  Tip: Have your name put on the account so it                     will be an easy transition. If possible, combine checking and/or savings so they’re all at one bank. 

     Tax return

     Deeds to property or loans outstanding

     Pension documents, annuity contracts

     Vehicle title

     Utility bills or other bills that are paid on a regular basis Tip: When you take        responsibility for payment, call and have them put on auto-pay.

     Medicare and supplemental insurance card information Tip:The cards should be available for the parent to have access to the original, so make copies  

     Health care proxy and/or Hipaa agreement to authorize release of medical information  

     Medical patient history

     List of all medications Tip: This is extremely important because of the affect they may have on your parent; some drugs cause serious side effects on the elderly. 

I have found two excellent, free websites that offer resources to help:

theconversationproject.org  has downloadable Starter Kits, one which is specifically designed for the loved ones of someone with dementia

eforms.com   has forms authorization for someone to receive health information about a patient which are listed by state. It also explains how to obtain health information

A Reason For Hope

In this time of increased political divisiveness and lack of confidence in our congressional representatives to work together and make effective decisions to run the country, finding evidence of compromise on an issue brings hope.

On September 28, 2018 a bill was signed into law that allocated $2.3 billion dollars to be included in the 2019 budget for Alzheimer’s and dementia research under the auspices of the National Institutes of health (NIH) . The congressional members who sponsored the bill included four Republicans, and four Democrats.

Alzheimer’s is indeed the most expensive disease in the country, costing an estimated $277 billion–including $186 billion in direct costs to medicare and medicaid–in 2018. As the number of those afflicted increases, so will the cost. There are 5 million Americans living with Alzheimer’s today; it is predicted this number will rise to 14 million by 2050. With the increase in funding, scientist are able to work at a faster pace to explore ways to reduce risks, develop drugs or other potential treatments to stop or slow the disease. 

In 2011 the National Alzheimer’s Project Act (NAPA) was passed which focused on the need for resources for research and the needs of family caregivers with a goal to find effective treatment of Alzheimers/dementia by 2025. Since that time, the federal government has continued to be supportive. The monies allocated to NIH from 2011 to the present have quadrupled, and continue to be spent on research and programs to help caregivers.

Among the many groups that keep congress aware of the need for funding for Alzheimer’s and dementia, one group stands out. Alzheimer’s Impact Movement (AIM), the advocacy arm of the Alzheimer’s Association. The group is very active in keeping our representatives aware of what is needed to help those afflicted with Alzheimer’s and those who care for them, as well and working with government agencies that oversee the research and programs that impact dementia and Alzheimer’s.
AIM federal goals are:

Increase the Commitment to Alzheimer’s Research

Build an Alzheimer’s Public Health Infrastructure

Educate Providers on Palliative and Hospice Care

State policy is also vital to the work that the Alzheimer’s Association is doing to meet the needs of individuals living with Alzheimer’s and their families. State officials determine regulatory and statutory standards for dementia training, control spending on state respite care dollars, designate spending for state long-term care services, and control Medicaid spending which can affect eligibility and scope of benefits – all of which can have a direct effect on families impacted by Alzheimer’s disease.
AIM state goals are:

Implement and update state Alzheimer’s disease plans

Improve dementia training

Increase early detection and diagnosis of Alzheimer’s

Educate the public about risk reduction

Preserve Medicaid

Aim was very active in the last election and seeks volunteers on a continuous basis to meet with local representatives, engage on social media, coordinate events, draft ‘letters to the editor’ or assist in other ways to bring awareness to the effects of Alzheimer’s.

Research

A major discovery has been made in the research of Alzheimer’s disease, as reported in the July 2018 edition of JAMA Neurology. Researchers at Yale University Alzheimer’s Research center have been able to measure the density of neural synapses in living patients. Up until the present, measurement of synaptic density was only possible in brains of people after they died.

Levels of a certain protein, SV2A, found in the transmission of neurotransmitter chemicals from one neuron to another were measured with position emission tomography (PET). The participants with MCI or mild Alzheimer’s disease who were compared to cognitively unimpaired individuals were found to have significantly less SV2A in the neural synapses in the hippocampus indicating a decrease in synaptic binding. The hippocampus is the part of the brain that forms memories, and it has been established that there is a relationship to damage in that area and Alzheimer’s disease.

The PET scan results also correlated with scores on episodic (short term) memory tests as well as those for Alzheimer’s. Other brain imaging tests, though protein was measured, did not offer the correlation with tests for cognition, which is fundamental to the study.

This important breakthrough of a reliable test for synaptic density in living people can provide a better measure of disease progression and help in evaluation of treatment with drugs in clinical trials.

A Swedish study that spanned four decades and involved 200 women discovered that those who have high levels of physical activity in middle age are 90% less likely to develop dementia as compared to women who are moderately fit. The women were tested for physical fitness by means of a bicycle test and were monitored and tested for evidence of dementia. They found that the average age for the onset of dementia was 90 for those highly fit and 79 for moderately fit women. Reference: Mind Report.newsmax.com

If that doesn’t make you want to get up and move, this next study will!

Multiple studies have shown that physical exercise helps to protect memory and cognitive function. It can also increase the size of the hippocampus, where memories are created. Research conducted at UCLA explored the impact of sitting and the brain’s hippocampal thickness. After recruiting 35 volunteers they recored how many hours they spent sitting each day the previous week. They then performed MRI scans to measure the medial temporal lobe where new memories are formed. There was a correlation between the number of hours of sedentary behavior and thinning of the lobe.  Note: This was a small study and more research needs to be done and variables taken into consideration before general conclusions can be drawn.

 Do you know anyone hard of hearing who doesn’t always wear their hearing aids? They may not want to bother or want to deliberately tune people out. Let them know: Loss of hearing is a significant risk factor for dementia.

Experts don’t know yet what links hearing loss to dementia, but it is suggested that it may be due to the decrease in social interaction. If you don’t understand what is being said and don’t participate fully in conversations, you may lose the benefits that come from that type of mental stimulation. Reference: Alzheimer’s Association

A Medical Assessment

You see your parent or loved one begin to have memory problems: they ask the same questions over and over; can’t remember where they placed something; have difficulty making decisions; forget to pay bills. After administering an informal memory or task test you believe your loved one has dementia. Now what? It is time for a doctor’s opinion. 

You don’t need to rush to see a neurologist unless you think the dementia is a result of a recent head trauma. Your primary care doctor or internist, preferably one who is familiar with the patient’s history, should be okay to start. If you are in a position to choose a doctor, try to find someone who specializes in working with older patients. When my mother moved away from her home to live closer to me, I first chose a general practitioner who was near her facility and recommended by others. As her condition worsened, I sought out a geriatric doctor.

 th-3.jpeg

What to expect in a medical assessment for dementia:

  • The first step in a diagnosis is a thorough physical and medical history evaluation. The doctor wants to rule out any conditions that may be related to the onset of dementia. Vision, hearing, cardiovascular, or thyroid disorders can have a direct effect on memory.

  • The doctor may administer a test to assess memory or simply ask the patient a few questions. After working with aging patients for many years, some doctors are familiar with the responses and behaviors of those exhibiting the signs of dementia and don’t need a detailed analysis.

  • Blood work will be ordered. The American Academy of Neurology recommends the following evaluation: 

                    Complete bloodcell count

                    Electrolyte levels in the blood (potassium, sodium and chloride)

                     Blood levels of glucose, urea nitrogen and creatinine

                     Blood levels of vitamin B12

                    Liver  and thyroid function tests

                    Depression screening

                    Noncontrast computed tomography (CT) or magnetic resonance imaging                                                                                        (MRI)

  • After gathering all the information about the patient, the doctor can then do an evaluation. First, a determination is made if the dementia is reversible due to conditions such as a brain tumor, depression, vitamin deficiency, hydrocephalus, or toxic reaction to a medication. If these conditions are eliminated as a cause of dementia s/he can then assess the symptoms. Certain diseases, such as Huntington’s Disease or Lewy Body Dementia are accompanied by certain behavioral markers that the doctor can identify, So the absence of these markers points to Alzheimer’s. Even though over 60% of dementia cases end up with Alzheimer’s Disease and the doctor probably suspects this is the case, this process of elimination is crucial so the doctor can decide how to proceed to help the patient.

    In many instances a diagnosis of Alzheimer’s is often not given immediately. Instead, the doctor may give the determination of Mild Cognitive Impairment (MCI). This could be called the beginning stage of Alzheimer’s, but there are some people who do not process beyond this stage, however, for the majority, with further cognitive decline, it leads to Alzheimer’s.

     

  • Medications

    With a diagnosis of MCI the doctor may prescribe iron or other vitamins along with an antidepressant. If you have heard of supplements that may decrease the effects of dementia you need to ask the doctor his opinion. Be wary of supplements accompanied by a strong sales pitch. While gingko biloba is heavily touted, research has shown minimal positive results. Current research that shows promise include a mix of Vitamin E, vitamin C, alpha lipoic acid, coenzyme Q10, omega-3 fatty acids, curcumin and Huperzine A.

    There are two types of drugs approved by the FDA for use by Alzheimer’s patients. The first, Cholinesterase inhibitors, slow down the breakdown of acetylcholine, an important chemical linked to the formation of new memories. It is sold under the name Aricept, Exelon and Razadyne. The second, NMDA receptor antagonist, helps block the activity of the neuro-transmitter glutamate by binding it to NMDA receptors on brain cells. It is sold under the name Namende, NamendaXR and Namzaric. It should be noted that while these drugs may ease symptoms associated with Alzheimer’s disease, they may only work for a short period of time, and do not halt the disease.

    Note: Home-screening tests for Alzheimer are available, but the medical profession and the Alzheimer’s Association strongly do not approve of their use. They do not prove who does not have dementia and can cause undue psychological  anguish. There is also a test that those without dementia can request that identifies a APOE gene type that can signal a person is at risk for Alzheimer’s, but again, it is discouraged. There is the possibility that the person may not get the disease, and would spend needless time worrying instead of enjoying life.

Screening for Dementia

Say, you are worried about your mother who seems to not remember what you had just told her.
Perhaps your husband has taken the wrong turn a few times on the way to a favorite restaurant.
Maybe in conversation you have searched for a word to explain something. You know it is there, but it’s just out of reach. 

Is this dementia? Alzheimer’s?  You are familiar with the signs, but how do you know for sure?

Let’s put your own mind at ease, first, by looking at what is considered normal aging and what is abnormal. Distinguishing between normal memory loss and dementia symptoms is not an exact science but there are some clues to look for:

Are memory changes typical aging or symptoms of dementia?
Typical aging: Symptoms of dementia:
You or a loved one complain about memory loss but are able to provide detailed examples of forgetfulness Complain of memory loss only if asked; unable to recall specific instances
Occasionally search for words Frequent word-finding pauses, substitutions
May have to pause to remember directions, but don’t get lost in familiar places Get lost in familiar places and takes excessive time to return home
Remember recent important events; conversations are not impaired Notable decline in memory for recent events and ability to converse
Interpersonal social skills are at the same level as they’ve always been Loss of interest in social activities; may behave in socially inappropriate ways
Adapted from: The American Medical Association

It is reassuring to know that three-fourths of people over 50 report that their memory is not as good as it once was, and of those who complain about memory problems only 10% have Alzheimer’s or dementia.

If you have definite concerns there are a few tests or questionnaires that can be helpful in clarifying whether a person may have dementia.
Be aware that these cannot be used as diagnostic tools except by a professional. If, after administering the tests you see a problem, you should take the test and the person to a doctor who is able to give you some insight and direction.

The Clock Drawing Test

Have the person draw a clock by hand on a large piece of paper.
Have the person draw the face of a clock and put the numbers in the correct positions.
Then have them draw the hands to indicate the time like 3:40 – one hand of the clock on 3 and the other on the 8.

 Scoring:  assign the following points for each part of the drawing
1 point for a closed circle
1 point for properly placed numbers
1 point for including all twelve numbers
1 point for properly placed hands

If the person cannot draw the clock or if it looks abnormal they would fall into the category of “probably” suffering from mild cognitive impairment or dementia. Many people that cannot pass this test might be suffering from some other illness. This is why it is necessary to consult your doctor.

MIni-Cog Test for Dementia and Alzheimer’s

First, name three objects and then ask the person being tested to repeat them back to you (for example, chair, house, apple). If the person cannot repeat the three objects after a few tries (cannot learn them), please consult a physician immediately.
If the person is successful give them another task for about ten minutes or the clock drawing test.
Next, ask the person to repeat the words/objects from the first part of the test.
If the person is unable to repeat any of the words, they might be categorized as mildly cognitively impaired or suffering from dementia.

Prevention

How do you prevent dementia or Alzheimer’s? Let me tell you, first of all, there is no magic pill. Doctors and scientists are working very hard to find a cure or identify factors that lead to the condition, but there is no miracle drug or procedure that will stop its progression–so far.

The ‘anti-aging’ tag on a label is a well-used ploy to sell, as are a plethora of products that purport to increase your memory or slow down the aging process. Equally persistent are ads for  products with formulas fabricated to increase your mental acuity. Most are based on incidental research and contain plant byproducts or vitamins, some of which are truly essential to good health, but not the panacea they claim.  It is always a good idea, though, to check the ingredients, especially those that refer to the brain.

While there is no guarantee that you will develop dementia, there are steps you can take that may decrease your chances. It is not surprising to recognize that the prescription for protecting your brain is the same as maintaining a healthy body. 

Diet
The Mediterranean diet based on a high intake of fruits and vegetables, whole grains and fats from fish, nuts and olive and vegetable oils has been found to slow cognitive decline.
     • In longitudinal studies those who followed the Mediterranean diet performed better on cognitive tests and than the control group, and were able to cut their risk for Alzheimer’s disease by half.

     • A study commissioned by the National Institute on aging found that people who consumed fish once or more per week had a 60% lower risk of developing Alzheimer’s disease as compared to those who did not.
     • High intake of fruits and vegetables, rich in free radical-fighting antioxidants, help prevent oxidative damage to the brain. Inflammation and damage from these free radicals most likely play a part in brain changes usually found in those with Alzheimer’s disease.
     • Use of olive oil, and eating fish rich in monounsaturated fats and omega-3, help quell inflammation throughout the body, including the brain.

     • Yes, it’s true, dark chocolate is good for your brain. In a study cited in the May 2016 edition of Appetite, participants were given a battery of tests that assessed cognitive function and then compared the scores with the amount of chocolate they typically ate weekly. The results showed that the cognitive scores rose with the amount of chocolate consumed.  

Vitamins and Minerals
If you eat a varied diet you should get most of the vitamins and minerals you need. In older adults it is important that they receive enough of the following:

    Vitamin D: 600I U ages 50-70; 800 IU over age 70; not to exceed 4,000 IU
    Vitamin B6: Men 1.7 mg a day; Women 1.5 mg a day
    Vitamin B12: 2.4 mcg a day
    Folate: 400 mcg a day
    Calcium: Women 51 and older 1,200 mg a day; Men 51-70 1,00 mg a day; Men 71 and older       1,200 mg a day

Reference:Office of Dietary Supplements National Institutes of Health www.ods.od.nih.gov

Exercise
Physical activity is needed for an over-all healthy body, but it is also essential to keep an adequate amount of blood flowing to the brain.
     • Regular exercise promotes better mental functioning by improving cerebral blood flow which aids in the prevention of cognitive decline. It also has the added benefit of releasing endorphins which make you feel better mentally.
    • 75 minutes of intense physical activity or 150 minutes of moderate physical activity a week is recommended. This does not always mean you must go to the gym. Participating in a sport or walking several times a week is as effective.

     • Not surprisingly, a high BMI (body weight index) increases your chance to develop dementia, especially vascular dementia or Alzheimer’s. Research on people in midlife, shows that for someone with a BMI between 25 and 29.9 the chance for dementia increases twofold, and for the obese person (BMI greater than 30) chances for dementia are four times greater. This could be a more powerful motivator than losing weight for a slimmer profile!

Sleep
Getting a good night’s rest is very important.
     • Doctors recommend six to seven hours of sleep a night for good mental functioning. This can be a real concern as we grow older and our sleep patterns  change. It is not unusual for seniors to have problems getting to sleep or waking often at night.
     • Certain studies have shown that participants who reported less that six hours of sleep a night, on average, and described their sleep as restless, had a greater buildup of plaque in the body than those who had a longer, restful sleep.
     • Sleep is when our brain consolidates and firms up new information. During this deep sleep, slow-brain-wave period, short term memories are transported from the hippocampus to the prefrontal cortex for long term storage. This probably explains why staying up most of the night to cram for a final wasn’t a good idea!

     • There are many effective, natural ways to improve your sleep; however, precautions must be taken with the use of sleeping pills. The American Geriatrics Society (AGS) recommends against the use of  sedatives such as diazepam (Valium), lorazepam (Ativan), alprazolam (Xanax) for the treatment of insomnia in older adults because of the risk of interruption of the sleep cycle and risk of cognitive impairment. Short term memory loss has also been associated with antihistamines (Benadryl) found in some sleep aides such as Tylenol PM.

Stress
Stress takes a heavy toll on the body.
     • High levels of stress cause the release of cortisol. Research has found when cortisol levels rise, cognitive performance declines. It is thought that chronic stress leads to malfunctions in the brain pathway that regulates cortisol levels and in turn affects brain cells.
     • Studies conducted on treatment of high blood pressure appeared to offer a side benefit. The Journal of Hypertension, June 2013, reported that medication for high blood pressure not only reduces a risk for stroke or heart attack, but may also help to prevent dementia, especially vascular dementia.

     • There are many ways to reduce stress, among them exercise and meditation, but ultimately it needs to be something tailored to the individual.
     • Smoking and excessive consumption of alcohol to relieve stress would, obviously, not be wise choices. An alcoholic drink a day, especially red wine, however, not only may help the heart but increase blood flow to the brain and prevent small strokes.

Mental Stimulation and Social Engagement
Keeping mentally active and socially engaged supports mental health and ultimately your brain cells.
     • Reading, playing board games, puzzles, dancing, playing a musical instrument or pursuing a hobby are ways to keep active which have been shown to lessen the chance for dementia. A five-year study of seniors 75 or older who kept active and mentally stimulated  were found to be less likely to develop dementia compared to a control group.
     • A Mayo Clinic study looked at inactivity by comparing the time spent watching television. They found that participants who spent an average of more than seven hours of TV a day were more likely to suffer memory loss than those who watched less.

     • There are commercial products on the market, principally computer programs that are promoted to stimulate mental acuity; research has shown, so far no notable differences between these programs and self selected activities such as games, puzzles, etc.
     • Talking with and interacting with people is also important for good mental health. It keeps the brain stimulated and your memory stronger. 

Another significant way you can help yourself is to not stress about what may or may not happen in the future and keep a positive attitude.
