What causes OCD?

Last update: 28/12/2024 Reading time: 1min

Obsessive Compulsive Disorder (OCD) affects 2-3% of the population. OCD is characterized by the appearance of repeated, persistent, unwanted and often anxiogenic ideas or images, on average around the age of 20 (around 14 in 25% of cases). These obsessions are often accompanied by repetitive behaviours that are supposed to neutralize the anxiety and anxiety that result from the obsessions, the compulsions. OCD is considered a disease of behaviour, thinking and emotion. Approximately one third of patients with OCD have had or are still having ICTs.

Causes of Obsessive Compulsive Disorder

The causes of cerebral dysfunction leading to obsessive compulsive disorder (OCD) are still unknown. There is a genetic predisposition, that is, an increased risk of developing the disease for relatives in the 1st degree of a patient. This risk is estimated at 8% compared to 2% in the general population, but not all the genetic variants associated with these disorders are yet known. The hypothesis of a mechanism of autoimmunity in some early forms of the disease (an inflammatory response directed against a component of the brain) has been advanced but not proven to date.
