• Obsessive-compulsive and related disorder due to a known physiological condition: fear of harming yourself or others deliberately or by mistake, contamination, need for orderliness, ordering, arranging, repeating words in their head, avoiding places/situations that could trigger obsessive thoughts, etc.

• Organic emotional labile asthenic disorder: rapidly changing feelings, violent mood swings, exhaustion after exerting even the slightest effort, dizziness, pain, and fatigue. 

Though the causes of some of these conditions are inconclusive, some may be induced by medication the patient is taking. Diagnosis will require a physical examination, an interview, and a copy of one’s medical history. 

Treatment, on the other hand, is usually either therapy or medication, in addition to receiving support from the family and an expert physician.
