1) Is the client "suspected" of having dementia or Alzheimers disease or has the client been actually "diagnosed" with dementia or Alzheimers disease?
It is important to know if there is only suspicion or an actual diagnosis of dementia or Alzheimer's disease. It is not uncommon for older clients to have memory loss and cognitive problems (i.e. language disturbances, failure to recognize objects, planning or organizing problems and inability to carry out motor functions in the presence of an intact motor system). Memory loss and cognitive problems are not "automatically" Alzheimers disease. They may be part of the normal aging process. They can also be caused by:
- Cerebral vascular disease (TIAs, mini-strokes, full strokes)
- Parkinson's disease
- Huntington's disease
- Brain tumors
- Normal pressure hydrocephalus
- Depression
- Schizophrenia
- Low thyroid function (hypothyroidism)
- Vitamin deficiency (B12 or folic acid)
- High serum calcium levels
- Substance abuse
Dementia is a clinical "state" not an actual disease. There are many different types of dementia (i.e. nearly 80). Dementia represents a decline from a previous higher level of functioning and involves memory as well as cognitive impairments.
If the client has suspected or a confirmed diagnosis of Alzheimers disease, then he or she will have some or all of the following problems:
- Memory and cognitive decline
- Behavioral disturbances
- Changes in personality
