The best thing a family member or friend can do for someone suffering from obsessive-compulsive disorder is to encourage and help that person to seek treatment. The person suffering from OCD might be embarrassed and try to hide symptoms or rituals, and mental rituals can be very difficult to recognize. Family members should be on the lookout for behavior changes and disruptions in everyday activities. Although loved ones might be tempted to help with rituals and behaviors, such as cleaning or checking door locks, this is counterproductive and reinforces the behaviors. A critical reaction to the behaviors can also increase anxiety for the person, so family members should strive to remain nonjudgmental and open-minded.
Family members will find it helpful to educate themselves about the disorder. Sufferers of OCD can be frustrating to deal with, and knowing more about the condition will increase the likelihood of those around them supporting and helping the sufferer. Once therapy has begun, supportive friends and family can make all the difference to recovery.
