Dementia Law and Legal Definition

Senile is a term that refers to a group of symptoms involving progressive impairment of brain function. Dementia may be diagnosed when two or more brain functions are impaired. These functions include language, memory, visual-spatial perception, emotional behavior or personality, and cognitive skills (such as calculation, abstract thinking, or judgment). Dementia usually appears first as forgetfulness. Other symptoms may be apparent only with neurologic examination or cognitive testing.

Dementia progresses slowly from decreased problem solving and language skills to difficulty with ordinary daily activities to severe memory loss and complete disorientation with withdrawal from social interaction.
