INTRODUCTION

It’s normal, on occasion, to go back and double-check that the iron is unplugged or worry that you might be contaminated by germs, or even have an occasional unpleasant, violent thought. But if you suffer from obsessive-compulsive disorder (OCD), obsessive thoughts and compulsive behaviors become so consuming they interfere with your daily life. OCD is an anxiety disorder characterized by uncontrollable, unwanted thoughts and ritualized, repetitive behaviors you feel compelled to perform. If you have OCD, you probably recognize that your obsessive thoughts and compulsive behaviors are irrational—but even so, you feel unable to resist them and break free.

Like a needle getting stuck on an old record, OCD causes the brain to get stuck on a particular thought or urge. For example, you may check the stove 20 times to make sure it’s really turned off because you’re terrified of burning down your house, or wash your hands until they’re scrubbed raw for fear of germs. While you don’t derive any sense of pleasure from performing these repetitive behaviors, they may offer some passing relief for the anxiety generated by the obsessive thoughts.

You may try to avoid situations that trigger or worsen your symptoms or self-medicate with alcohol or drugs. But while it can seem like there’s no escaping your obsessions and compulsions, there are plenty of things you can do to break free of unwanted thoughts and irrational urges and regain control of your thoughts and actions.

Obsessions

Obsessions are recurrent and persistent thoughts, impulses, or images that cause distressing emotions such as anxiety or disgust. Many people with OCD recognize that the thoughts, impulses, or images are a product of their mind and are excessive or unreasonable. Yet these intrusive thoughts cannot be settled by logic or reasoning. Most people with OCD try to ignore or suppress such obsessions or offset them with some other thought or action. Typical obsessions include excessive concerns about contamination or harm, the need for symmetry or exactness, or forbidden sexual or religious thoughts.

Compulsions

Compulsions are repetitive behaviors or mental acts that a person feels driven to perform in response to an obsession. The behaviors are aimed at preventing or reducing distress or a feared situation. In the most severe cases, a constant repetition of rituals may fill the day, making a normal routine impossible. Compounding the anguish these rituals cause is the knowledge that the compulsions are irrational. Although the compulsion may bring some relief to the worry, the obsession returns and the cycle repeats over and over.

SIGNS AND SYMPTOMS

Just because you have obsessive thoughts or perform compulsive behaviors does NOT mean that you have obsessive-compulsive disorder. With OCD, these thoughts and behaviors cause tremendous distress, take up a lot of time (at least one hour per day), and interfere with your daily life and relationships.

Most people with obsessive-compulsive disorder have both obsessions and compulsions, but some people experience just one or the other.

Common obsessive thoughts in OCD include:

·Fear of being contaminated by germs or dirt or contaminating others

·Fear of losing control and harming yourself or others

·Intrusive sexually explicit or violent thoughts and images

·Excessive focus on religious or moral ideas

·Fear of losing or not having things you might need

·Order and symmetry: the idea that everything must line up “just right”

·Superstitions; excessive attention to something considered lucky or unlucky

Common compulsive behaviors in OCD include:

·Excessive double-checking of things, such as locks, appliances, and switches

·Repeatedly checking in on loved ones to make sure they’re safe

·Counting, tapping, repeating certain words, or doing other senseless things to reduce anxiety

·Spending a lot of time washing or cleaning

·Ordering or arranging things “just so”

·Praying excessively or engaging in rituals triggered by religious fear

·Accumulating “junk” such as old newspapers or empty food containers

Not all rituals or habits are compulsions. Everyone double checks things sometimes. But a person with OCD generally:

·       Can't control his or her thoughts or behaviors, even when those thoughts or behaviors are recognized as excessive

·       Spends at least 1 hour a day on these thoughts or behaviors

·       Doesn’t get pleasure when performing the behaviors or rituals, but may feel brief relief from the anxiety the thoughts cause

·       Experiences significant problems in their daily life due to these thoughts or behaviors

Some individuals with OCD also have a tic disorder. Motor tics are sudden, brief, repetitive movements, such as eye blinking and other eye movements, facial grimacing, shoulder shrugging, and head or shoulder jerking. Common vocal tics include repetitive throat-clearing, sniffing, or grunting sounds.

Symptoms may come and go, ease over time, or worsen. People with OCD may try to help themselves by avoiding situations that trigger their obsessions, or they may use alcohol or drugs to calm themselves. Although most adults with OCD recognize that what they are doing doesn’t make sense, some adults and most children may not realize that their behavior is out of the ordinary. Parents or teachers typically recognize OCD symptoms in children.

CAUSES

OCD is a common disorder that affects adults, adolescents, and children all over the world. Most people are diagnosed by about age 19, typically with an earlier age of onset in boys than in girls, but onset after age 35 does happen. 

Genetics

Twin and family studies have shown that people with first-degree relatives (such as a parent, sibling, or child) who have OCD are at a higher risk for developing OCD themselves. The risk is higher if the first-degree relative developed OCD as a child or teen. Ongoing research continues to explore the connection between genetics and OCD and may help improve OCD diagnosis and treatment.

Brain Structure and Functioning

Imaging studies have shown differences in the frontal cortex and subcortical structures of the brain in patients with OCD. There appears to be a connection between the OCD symptoms and abnormalities in certain areas of the brain, but that connection is not clear. Research is still underway. Understanding the causes will help determine specific, personalized treatments to treat OCD.

Environment

An association between childhood trauma and obsessive-compulsive symptoms has been reported in some studies. More research is needed to understand this relationship better.

In some cases, children may develop OCD or OCD symptoms following a streptococcal infection—this is called Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS). 

TREATMENTS AND THERAPIES

OCD is typically treated with medication, psychotherapy, or a combination of the two. Although most patients with OCD respond to treatment, some patients continue to experience symptoms.

Sometimes people with OCD also have other mental disorders, such as anxiety, depression, and body dysmorphic disorder, a disorder in which someone mistakenly believes that a part of their body is abnormal. It is important to consider these other disorders when making decisions about treatment.

·       Psychotherapy. Cognitive behavioral therapy can help change your thinking patterns. In a form called exposure and response prevention, your doctor will put you in a situation designed to create anxiety or set off compulsions. You’ll learn to lessen and then stop your OCD thoughts or actions.

·       Relaxation. Simple things like meditation, yoga, and massage can help with stressful OCD symptoms.

·       Medication. Psychiatric drugs called selective serotonin reuptake inhibitors help many people control obsessions and compulsions. They might take 2 to 4 months to start working. Common ones include citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac), fluvoxamine, paroxetine (Paxil), and sertraline (Zoloft). If you still have symptoms, your doctor might give you antipsychotic drugs like aripiprazole (Abilify) or risperidone (Risperdal).

·       Neuromodulation. In rare cases, when therapy and medication aren’t making enough of a difference, your doctor might talk to you about devices that change the electrical activity in a certain area of your brain. One kind, transcranial magnetic stimulation, is FDA-approved for OCD treatment. It uses magnetic fields to stimulate nerve cells. A more complicated procedure, deep brain stimulation, uses electrodes that are implanted in your head.
