Symptoms of Obsessive Compulsive Disorder
OCD typically presents with both obsessions and compulsions, though in some cases only one type is present.
Obsessions
Unwanted intrusive thoughts, images, or urges causing significant discomfort. Common themes:
- Harm: Intrusive fears about hurting yourself or others
- Contamination: Fears about germs, sickness, or touching surfaces
- Unacceptable thoughts: Taboo sexual, religious, or aggressive intrusive thoughts that don’t align with one’s values
- Symmetry: Intense need to keep things ordered or symmetrical
Compulsions
Behaviors or rituals carried out to reduce obsession-driven anxiety. Can be physical or mental. Provide only temporary relief — the cycle repeats. Common types:
- Checking: e.g., checking the oven multiple times
- Cleaning: e.g., excessive hand washing
- Counting/repeating: e.g., repeating a behavior a specific number of times
- Ordering: e.g., rearranging objects to achieve exact symmetry
- Seeking reassurance: e.g., asking others to confirm a feared action won’t happen
- Avoidance: Avoiding places, people, or situations that trigger obsessions
Causes of OCD
There is no single cause of OCD; several risk factors can contribute to the likelihood of someone developing OCD.
- Family history: Genetics plays a role; 20–40% of first-degree relatives in OCD cases have obsessional traits.
- Co-occurring conditions: Having depression or anxiety may contribute to developing OCD.
- Trauma: Trauma or high-stress situations may trigger OCD.
- History of abuse: Physical or sexual abuse, particularly during childhood, increases risk.
- Brain differences: Imaging studies show abnormalities in the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), and caudate nucleus in people with OCD.
Types of OCD
- Cleaning/Contamination OCD: Focused on fears of contamination; excessive washing or cleaning to relieve distress. Learn more.
- Order/Symmetry and Counting OCD: Intense urge to arrange things until they feel exactly right. Learn more.
- Harm OCD: Extreme worry about harming yourself or others; often managed through checking rituals. Learn more.
- Hoarding OCD: Now recognized as its own DSM-5 diagnosis; involves compulsive accumulation of items until living space becomes unusable. Learn more.
Additional types include relationship OCD, retroactive jealousy OCD, Pure O OCD, scrupulosity OCD, existential OCD, and false memory OCD.
Treatment for OCD
Therapy and medication are often most effective in combination. Treatment type and duration depends on symptom severity and quality-of-life impact.
1. Therapy
- CBT: Cognitive behavioral therapy helps people identify unhelpful thought patterns and how they drive behavior, then develop healthier responses. Includes relaxation techniques; work outside of sessions is needed for best results.
- ERP (Exposure and Response Prevention): An offshoot of CBT developed specifically for OCD. The patient is exposed to their trigger, then prevented from carrying out the compulsion. Over time this desensitizes the fear response. Example: touching a doorknob without washing hands afterward.
2. Medication
Patients with more severe symptoms often require medication alongside therapy. OCD patients typically require higher doses and may need 10–12 weeks for full effect.
- SSRIs: Most commonly prescribed. Include Lexapro, Prozac, Paxil, Luvox, and Zoloft.
- SNRIs: Venlafaxine (Effexor) has clinical evidence supporting OCD treatment.
- TCAs: Clomipramine (Anafranil) was the first OCD medication proven effective. Higher side-effect risk than SSRIs/SNRIs; not typically first-line.
- Antipsychotics: Added when an antidepressant alone is insufficient. Risperidone (Risperdal) is most studied for OCD augmentation.
3. Alternative & Natural Treatments
Lifestyle changes and mindfulness training can support symptom management alongside therapy and medication.
