Defining Dementia

Since my main focus of this blog will be on dementia we first need a clear definition of what it means. According to the New World Dictionary the psychiatric definition is “the loss or impairment of mental powers due to organic causes.” People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

When I told people my mother was suffering from Dementia, they often said, “Oh Alzheimer’s.”, however, the two words are not synonymous. Dementia is a term used for a collection of symptoms which are caused by injury or disease to the brain. Alzheimer’s is a disease.

While it is true that the great majority of those with the symptoms of dementia may develop Alzheimers disease, it is only one kind. Other diseases that exhibit its symptoms are vascular dementia, Lewy body dementia, frontotemporal dementia, Hunington’s disease, and Creutzfelt-Jacob disease. Dementia symptoms also can occur in those whose brain has been affected by injury or drugs.

In the beginning my mother had what is called Mild Cognitive Impairment (MCI) which is early dementia. She had trouble with tasks that required reasoning, and could not remember what was said in conversations. She was able to live independently at first, but gradually her symptoms worsened. It is at this juncture that conflicts occur. Though the family realizes their loved one needs help, the person with dementia is usually not ready to give up his/her independence. And so, the caregiver challenge begins!

Here are some signs common to dementia
Impaired judgement
Faulty reasoning
Inappropriate behavior
Loss of communication skills
Disorientation to time and place
Gait, motor, and balance problems
Hallucinations, paranoia, agitation

Someone with dementia symptoms may
repeatedly ask the same questions
become lost or disoriented in familiar places
be unable to follow directions
be disoriented about the date or time of day
not recognize or be confused about familiar people
have difficulty with routine tasks such as paying the bills
neglect personal safety, hygiene, and nutrition

 According to the US National Institutes of Health:National Institute of Neurological Disorders and Stroke  Although it is commom in very elderly individuals, dementia is not a normal part of the aging process.
