<s>[INST] Yes.My wife have to have the blinds in the house turned a certain all the time, and she checks the door with her hand after she locks it, when I lock the door she will come behind me and check to make sure it is locked.what kind of disorder could this be. [/INST] Hello and thanks for your query. I understand your concern about your wife abnormal behavior. From the description of her symptoms, it appears that your wife could be suffering from a psychiatric disorder called Obsessive Compulsive Disorder (OCD). Such repeated checking behaviors are called compulsions and are part of OCD. Some persons may have other compulsions like repetitive washing, cleaning, etc. Persons with OCD are able to recognize that their repetitive behaviors are irrational and unwanted, but still they are not able to control them. This causes a lot of distress and discomfort. There are effective treatment options available for OCD - in the form of SSRI medication and psychological therapy (CBT). So, I would advise you to convince your wife to consult a psychiatrist and start appropriate treatment. </s>
