Loss of memory: By definition, dementia is 1) loss of memory & 2) loss of function, whether speech, coordination, planning, etc. Strange behavior can result from not remembering or perhaps from not understanding. Crazy, aggressive confused behavior that's different from usual can also be a result of infection, pain, change in environment, some medical ailment, or even medication. Best to discuss w/treating doc

Causes of dementia: Lewy body disease is a leading cause of dementia in the elderly. With this condition people have abnormal protein structures in certain areas of the brain. Many small strokes can cause vascular dementia. Abnormal brain functioning is associated with these conditions.
