In some conditions that affect brain function, changes in behavior and personality occur. Certain areas of the brain, such as the frontal and temporal lobes, control behavior. When these areas are damaged, individuals have difficulty controlling temper, actions or feelings. This can result in behaviors that are unusual and unexpected.
These behaviors can be unsettling and difficult to understand. Individuals can become impulsive, act inappropriately and loose control over behavior. Some patients develop a preoccupation with a certain subject, like finances, food or sex. These preoccupations can be irritating, embarrassing and in some cases, present concerns regarding safety.
It is best to be prepared for these behaviors. Inform those who are with the individual about the brain disease and the behaviors associated with it. Many times inappropriate behaviors are based on normal feelings that are some expressed in a way that is inappropriate for the situation.
