An Essential Guide to Understanding Causes of OCD
The exact cause of obsessive-compulsive disorder (OCD) is unknown, but it is likely influenced by a combination of genetic, brain structure and function, and environmental factors, including a history of trauma or stress. Psychological factors like perfectionism and cognitive beliefs, such as an intolerance for uncertainty, may also play a role.
Biological factors
Genetics: A family history of OCD increases the risk, and genetics may account for a significant portion of the risk for developing the disorder.
Brain structure and function: Some research indicates that people with OCD may have differences in certain brain areas, such as the orbitofrontal cortex, anterior cingulate cortex, and basal ganglia. There can also be a connection to brain abnormalities or high levels of activity in specific areas.
Brain chemistry: Low levels of the neurotransmitter serotonin, which is involved in mood and other functions, are thought to be a contributing factor for some people.
Environmental factors
Trauma and stress: Stressful life events, trauma, abuse, neglect, or a head injury can increase the risk of developing OCD.
Infections: In some cases, particularly in children, OCD symptoms can be triggered by infections, like streptococcal infections (e.g., strep throat).
Cognitive and psychological factors
Faulty beliefs: Distorted beliefs, such as perfectionism, a sense of inflated responsibility, and an intolerance for uncertainty, can contribute to obsessions and compulsions.
Behavioral learning: The behavioral theory suggests that individuals may learn to associate certain objects or situations with fear, and they avoid those things by performing compulsive rituals that provide temporary relief.
Personality traits: Personality traits like perfectionism have been linked to an increased risk of OCD.
