Common Causes And Complications Of OCD

Genetics And Family History

Research shows genetics and family history play a large role in the development of obsessive-compulsive disorder. Some of this may be because the brain abnormalities involved in OCD can be passed down through families. Being raised in a household with family members with untreated obsessive-compulsive disorder can also increase an individual's risk of developing obsessions and compulsions. The National Institutes of Health funded a study to examine DNA and its correlation to this condition. The study drew a correlation between OCD, similar anxiety disorders, and a mutation of the serotonin transport gene found in humans. Some patients with severe cases of obsessive-compulsive disorder also have a second mutation within the same gene. Around one-fourth of OCD patients have an immediate member of the family who has the disorder. Studies done on twins indicated if one identical twin has OCD, the other is more likely to develop the condition than if the twins are fraternal. The findings in the twin studies suggest genetics are responsible for between forty-five and sixty-five percent of an individual's risk of developing OCD.

Increased Stress

Increased stress can be a factor in how symptoms of obsessive-compulsive disorder present. Some individuals are under the impression stress itself is enough to cause OCD, but this isn't the case. An individual who already has the condition, though, will often see a worsening in symptoms when they experience stress. Illness, fatigue, and anxiety can have an impact on the severity of symptoms. Changes in routine can cause increased stress, leading to a vicious cycle of worsening symptoms. AN obsessive-compulsive disorder patient who hasn't experienced visible symptoms for a while might have a symptom flareup following a stressful life event. Severe trauma can cause symptoms to begin. Common traumas include the death of a loved one or abuse. Some life changes that can cause symptoms to recur include transitions to new schools or workplaces, moving into a new home or community, marriage, divorce, the birth of a child, or the birth of a sibling. Some individuals have developed new symptoms following the stress of natural disasters like hurricanes and earthquakes.
