Broadly, if the left side of the brain is affected, the result is usually depression. If it is on the right side, the result is usually mania.

If a deeper structure in the brain is affected, there can be anxiety disorders, obsessive compulsive disorders, sometime with Parkinson's features.

Damage to the frontal portion of the brain usually results in personality alterations and apathy.

Damage to the middle part of the brain creates an uninhibited reaction such as displaying no social etiquette and sexual inpropriety. The display of actions is similar to someone who is heavily drunk. But it is important to compare the Survivor's behavior to the personality pior to the Stroke.

One of the main differences in a normal psychiatric population is that Stroke causes result in visual hallucinations and very rarely auditory hallucinations. A person with psychiatric problems that has not had a Stroke would be more likely to have auditory hallucinations and not so much the visual hallucinations. Another residual deficit in Stroke Survivors can be disillusions and problems with hearing.

The main areas that we will analyze in more detail are:

• Mood Disorders and Stroke
  
  
• Mania and Stroke
  
  
• Anxiety Disorder and Stroke
  
  
• Stroke Induced Psychosis
  
  
• Stroke and Delusions
