Alzheimer's Disease

Motivation

While memory loss is a symptom that people typically first think of when they think Alzheimer's disease , there are also a range of behavioural problems that occur. Damage in certain areas of the brain can cause behavioural problems which can affect both families and caregivers. The majority of these behavioural problems can be traced to damage in the frontal lobe .

The frontal lobe is responsible for many important higher level functions such as thinking, reasoning, and language. These are the functions that make us who we are, to ourselves and others. Thus, when this area suffers damage from Alzheimer's or another disease, it can greatly affect a person, and those who care about him/her.

There are three areas in particular which affect how each of us behaves: motivation, goal-directed behaviours and inhibition . The part of the brain responsible for motivation is the frontal lobe. It is what gives a person their sense of get-up-and-go. Getting out of bed and starting your day or going out with friends to a movie requires motivation. When damage occurs to the frontal lobe, person with Alzheimer's disease may often appear 'lazy' or 'apathetic' to others. They lack the motivation to do tasks or activities they once did. Withdrawal from social and leisure activities is a common complaint of persons with Alzheimer's disease and caregivers.
