what are the symptoms of dementia
Dementia is not a normal part of aging. Dementia is not a single disease in itself, but a general term to describe symptoms such as impairments to memory, communication, and thinking. While the likelihood of having dementia increases with age, it is not a normal part of aging.
Other disorders leading to symptoms of dementia include: 1  Frontotemporal dementia (also known as Pick's disease) 2  Normal pressure hydrocephalus (when excess cerebrospinal fluid accumulates in the brain)  Posterior cortical atrophy (resembles changes seen in Alzheimer's disease, but in a different part of the brain)
Behavioural changes: A person with dementia may seem different from his/her usual self in ways that are difficult to identify or explain. A person may become suspicious, irritable, depressed, apathetic, anxious, or agitated, especially in situations where memory problems are causing difficulties.
