Which other disorders cause dementia?

In addition to Alzheimer’s disease, other brain disorders of aging that affect thinking and memory include vascular dementia, dementia with Lewy bodies, Parkinson’s disease dementia, behavioral variant frontotemporal dementia, primary progressive aphasia that has logpenic, semantic, and non-fluent agrammatic variants, and normal pressure hydrocephalus. Each produces characteristic changes in thinking, memory, language, behavior, and/or movement that allow you and the doctor to know when to consider them as possible causes of your loved one’s dementia. Note that the dementia of every individual is unique, so the symptoms and signs that they will manifest are all different. However, when dementias reach the moderate to severe stage, most dementias looks similar, despite having different causes.
