Obsessive-compulsive disorder (OCD), also called obsessive-compulsive neurosis is a type of mental disorder in which an individual experiences obsessions or compulsions or both. Either the obsessive thought or the compulsive act may occur singly, or both may appear in sequence. Excessive thoughts (obsessions) that lead to repetitive behaviours (compulsions).

Obsessive-compulsive disorder is characterised by unreasonable thoughts and fears (obsessions) that lead to compulsive behaviours. OCD often centres on themes such as a fear of germs or the need to arrange objects in a specific manner. Symptoms usually begin gradually and vary throughout life.

OCD may be a result of changes in your body's own natural chemistry or brain functions or may have a genetic component. It may also be due to behaviors learned from the family members or learned over time.

The approach of homeopathic remedies is to balance the chemicals present inside the brain that can help people struggling with obsessive compulsive disorder.
