"Diagnosing OCD," by Osborn.

This chapter really goes in depth how to diagnose obsessive- compulsive disorder. OCD is diagnosed when obsessions and compulsions interfere significantly in a person's life. According to the general public, such as magazines and television, OCD has been diagnosed when a person thinks and carries a negative connotation, labeling them as an obsessional. But, the term "obsession" has a totally different meaning for mental health professionals. Obsessions are recurrent and persistent thoughts that are experienced as intrusive and inappropriate and that cause marked anxiety or distress. I agree with the mental health professionals because "obsession" is not a person who thinks a negative connotation, instead it is a endless, continous thought that might not be there all the time but it comes back from time to time and often effects the mental process.
The nature of complusions popularity is used to indicate anything done to excess but it is a repetition act that is performed according to rules that must be applied rigidly. Basically it is one that stresses the close relationship between compulsions and obsessions. What's interesting is that in the long run compulsions can only make obsession worse. Compulsions can be divided into two groups: behavorial and mental issues. For example, in the case of Howard Hughes, Hughes was a well known productive and successful person who passion was all about narcotics. But Hughes life was dominated by compulsions. He was afraid to eat, drink, or even be touched. So he wrote pages of memos for his staff on inconsequential items. Hughes germ obsessions drove him to hoarding whatever might contamination. This goes to prove how severe obsessions, along with compulsions, can be.
