[Social Behavioral Problems after Brain Injury]

Abstract

Various types of aberrant social behaviors may occur after brain injury. Some of these behaviors might be understood as direct consequences of brain injury; apathy, disinhibition, and executive dysfunction are the three major domains of aberrant social behaviors after injury of the prefrontal cortex. In addition, psychosis, pseudobulbar affect, depression, and fatigue are common symptoms that affect social behavior after brain injury. To evaluate behavioral symptoms, it is important to obtain information based on the context of patient's daily life. Individualized interventions such as pharmacotherapy, disease education and environmental control would improve the patient's social function.
