What is OCD?
Obsessive-Compulsive Disorder (OCD) is a widespread, persistent, and long-lasting mental illness in which a person experiences uncontrollable, recurrent thoughts (obsessions), urges to engage in certain actions (compulsions), and other symptoms.
What causes the OCD?
Experts are uncertain of OCD's precise cause. The environment, genetics, and anomalies of the brain are regarded to be contributing factors. It frequently begins in adolescence or early adulthood. However, it can also begin in infancy.
Can stress cause OCD?
Anything that generates stress, worry, or a sense of being out of control might set off an OCD episode. A person with OCD may experience obsessions and compulsions, especially with cleanliness, if they are diagnosed with cancer, for instance.
