Another major form is Obsessive Compulsive Disorder (OCD). Such a disorder causes one to experience temporary obsessions or repeated thoughts about usually inappropriate things and/or feel a strong urge to carry out a certain action or ritual.
Usually the patient is completely aware that the obsession or compulsion is a product of his or her own mind, attempts to ignore or neutralize the obsession or compulsion by other thoughts or actions and even feels that the actions and thoughts brought upon by such a disorder are excessive or unreasonable. However, children seem to be exempt from such control over the disorder. The actions or obsessions are distressing to the patient and time-consuming – usually taking about an hour a day.
All of the aforementioned anxiety disorders do not occur due to use of drugs or an existing medical condition. What differentiates them from a simple bout of anxiety or a minor, temporary obsession or fear is that they make the patient’s life very difficult, embarrassing and miserable – in all its social, marital, professional and personal aspects.
