Answer

I agree that it sounds as though your familu member is suffering from Obsessive-Compulsive disorder. There is no known cause for this disorder, though it is believed to be primarily related to abnormal serotonin levels in certain parts of the brain involved in regulating anxiety and behavior. While medications such as Lexapro or other "SSRI" (selective serotonin reuptake inhibitor) medications often do reduce obsessive thoughts, compulsive behaviors and anxiety, often counselling and behavioral therapy known as "exposure response prevention" are also needed. This involves exposing a patient to the situations or objects which cause them anxiety fuel their compulsive behaviors, and in doing so they gradually learn to deal with these things without acting compulsively or becoming over-anxious.

 

I have included the following link for information on Obsessive Compulsive Disorder and also how to find a physician who can treat your family member. I hope this has been helpful.
