Dementia in seniors over 65 is most commonly caused by Alzheimer's disease, notes Mayo Clinic. Unlike some forms of dementia, this type is irreversible and causes a decline in cognitive functions over a period of several years. Another kind of dementia that is common in seniors is called Lewy body dementia, and the outward signs are similar to those of Alzheimer's disease. Lewy body dementia often causes a sleep disorder that results in people acting out their dreams, and may also cause physical symptoms such as rigidity and tremors. People between 50 and 70 may experience a condition called frontotemporal dementia which creates movement and language problems and difficulty concentrating.

Dementia is a group of symptoms, not a specific disease, explains Healthline. It is sometimes the result of aging, but traumatic brain damage can also cause dementia. Progressive dementia is the most common type, and medical professionals use a tool called the Clinical Dementia Rating to determine which of five stages a patient is in. This tool measures a patient's abilities in several areas such as judgement, memory, personal care and community.
