What causes difficulty controlling emotions and inappropriate sexual behavior?
This is similar to the question about anger and aggression. Following a brain injury, some people lose appropriate boundaries when they experience sadness, happiness, and sexual feelings. This loss of inhibition and impulse control can result from the location of their brain lesions, or the trauma of the brain injury. Often a psychiatrist or psychologist who specializes in neurological cases is needed to help the person deal with the injury in a healthy way.
