Dementia is a condition of declining mental abilities, especially memory. Individuals with dementia may have trouble doing things they used to do such as keeping the checkbook, driving a car safely or planning a meal. They often have trouble finding the right word and may become confused when given too many things to do at one time. Individuals with dementia may also experience changes in personality, becoming aggressive, paranoid or depressed.

Dementia is a disabling disorder of both cognition and affect which impairs the higher mental processes of learning, thinking, decision-making and, especially, memory and is accompanied by changes in personality and ways of relating to other people.
