F07.8: Other organic personality and behavioural disorders due to brain disease, damage and dysfunction

Your behavior and thinking differs from that of the world around you. There is a physical reason for this.

Everyone has personal characteristics that are deeply rooted. The personality involves certain patterns: how one things, feels and behaves. Personal characteristic patterns can exist that can cause problems in one’s work and social environment. This usually happens when behavioral patterns and thought patterns differ greatly from those of the majority of the population. In your case, a physical disorder is causing your thoughts and behavior to be changed.
