My father suffered a severe right side ischemic stroke 10 years ago (100% caratid blockage). He has severe left side deficit. Recently, he has been exhibiting obsessive/compulsive and socially inappropriate behavior. When he first had the stroke, he was treated with Ritilin which seemed to keep him level. A few years ago, his family doctor took him off Ritilin and prescribed Zoloft. He has now been put on a nother anti-depressant medication--the name of which escapes me. Since he has been off Ritlin, his behavior seems to have worsended. What meds are typically prescribed to stroke patients for symptoms that my father is exhibiting? Is psycho-therapy/counseling efficacious in these situations?
