6 Key Concepts
Obsessive-Compulsive Disorder (OCD)
OCD is characterized by intrusive, recurrent obsessions (unwanted thoughts) and compulsions (behaviors) performed to relieve the obsessions. However, these compulsions provide only brief relief and ultimately strengthen the obsessions, creating a debilitating loop.
Obsessive-Compulsive Personality Disorder (OCPD)
OCPD is distinct from OCD, lacking the intrusive and unwanted nature of obsessions. Individuals with OCPD often welcome or enjoy their patterns of thought and behavior, which can involve a strong sense of delayed gratification and a desire for order, sometimes enhancing their function in certain areas of life.
Cortico-Striatal-Thalamic Loop
This neural circuit, involving the cortex, striatum (including basal ganglia), and thalamus, is thought to underlie OCD. Dysfunction in this loop leads to the repetitive thought-action cycles, with the thalamic reticular nucleus acting as a gate for which information and thoughts reach conscious perception.
Anxiety Tolerance
A core principle in treating OCD, particularly with cognitive behavioral therapy, is teaching patients to tolerate rather than relieve their anxiety. By confronting the utmost fear and suppressing compulsive actions, individuals learn that anxiety can exist without the need for immediate ritualistic relief, thereby disrupting the OCD loop.
Go and No-Go Behaviors
These refer to the generation of actions ('go') and the resistance or suppression of actions ('no-go'), primarily controlled by the striatum. In OCD, the striatum is involved in the compulsive 'go' behaviors or the 'no-go' avoidance of feared actions, reinforced by the transient anxiety relief.
Cognitive Inflexibility
This refers to challenges in task switching or adapting to new rules, a hallmark theme of OCD. Serotonin systems, though not directly implicated as the cause of OCD, have been shown to impact cognitive flexibility, suggesting an indirect link to some aspects of the disorder.
9 Questions Answered
OCD is characterized by intrusive, unwanted obsessions and compulsions that provide only temporary relief and ultimately strengthen the obsession. OCPD, however, does not involve intrusive thoughts; individuals often welcome or even enjoy their meticulous and orderly patterns, which can sometimes be adaptive.
OCD is extremely common, affecting 2.5% to 4% of people, and is ranked as the seventh most debilitating illness overall, not just psychiatric illnesses, due to the significant suffering and impairment it causes in daily life.
The general categories of OCD include checking (e.g., locks, stove), repetition (e.g., counting, repeated actions), and order (e.g., cleanliness, symmetry, completeness, or fear of contamination leading to disgust).
OCD is thought to be generated by dysfunction in the cortico-striatal-thalamic loop, a circuit involving the cortex (conscious perception), the striatum (action selection and suppression), and the thalamus (sensory and thought gating).
CBT for OCD aims to get patients to tolerate maximum anxiety by confronting their deepest fears and then deliberately preventing them from engaging in their usual compulsions, thereby interrupting the reinforcing loop between obsessions and compulsions.
SSRIs can significantly reduce OCD symptoms, but studies suggest that cognitive behavioral therapy is generally more effective. Combining SSRIs with CBT from the outset may not offer additional benefit over CBT alone, but adding CBT to existing SSRI treatment can provide further symptom reduction.
A placebo-controlled human laboratory study found that smoked cannabis, whether containing primarily THC or CBD, had little immediate impact on OCD symptoms and yielded smaller reductions in anxiety compared to placebo.
Studies show that females with OCD have elevated cortisol and DHEA, while males with OCD have elevated cortisol and reduced testosterone. These hormonal patterns suggest an overall reduction in GABA transmission, potentially contributing to increased excitation in brain networks involved in OCD.
Superstitions are beliefs linking irrelevant actions to outcomes, driven by the brain's desire for predictability and control. When repeated often enough, superstitions can become automatic and evolve into full-blown compulsions and obsessions, especially in individuals with a tendency towards OCD.
12 Actionable Insights
1. Seek Professional OCD Treatment
If you suspect you have persistent, intrusive obsessions and compulsions that cause distress or impair daily functioning, seek evidence-based treatment from a licensed clinician. This is crucial as most people with OCD do not seek treatment, leading to prolonged suffering.
2. Engage in Exposure-Based CBT
Work with a trained psychologist or psychiatrist in exposure-based cognitive behavioral therapy (CBT) for OCD. The therapy aims to progressively increase anxiety by confronting your deepest fears and then preventing the compulsive behavior, teaching you to tolerate anxiety without engaging in rituals.
3. Perform OCD Therapy Homework
Actively perform “homework” assigned by your clinician outside of therapy sessions. This is vital for challenging anxiety and interrupting compulsions in your home environment, as familiar surroundings can often trigger relapses.
4. Understand Thoughts Are Not Actions
Cultivate the understanding that intrusive thoughts are merely thoughts and not equivalent to actions. This realization is a fundamental step in OCD treatment, helping to reduce the urge to perform compulsions to suppress disturbing or taboo thoughts.
5. Avoid Substance Abuse for Anxiety
Do not use substances like alcohol or cannabis to suppress anxiety related to OCD. Suppressing anxiety is counterproductive to effective OCD treatment, which focuses on learning to tolerate and manage anxiety without compulsive behaviors.
6. Consult Physician for Drug Changes
Always consult with a licensed physician or psychiatrist before starting, stopping, or altering the dosage of any prescription drug for OCD. This ensures safety and appropriate management of complex drug interactions and side effects.
7. Add CBT to Existing SSRI Treatment
If you are currently taking an SSRI for OCD and experiencing some symptom reduction, consider adding cognitive behavioral therapy (CBT) to your regimen. Studies show that initiating CBT while on SSRIs can lead to further significant reductions in OCD symptoms.
8. Practice Yoga Nidra or NSDR
Engage in 10-minute sessions of Yoga Nidra or Non-Sleep Deep Rest (NSDR) to restore cognitive and physical energy. These practices involve lying still with an active mind and are supported by scientific data for their restorative benefits.
9. Consider Myo-Inositol Supplementation
Explore supplementing with 900 milligrams of myo-inositol, potentially in combination with other sleep aids. This dosage has been anecdotally reported to improve sleep quality, reduce anxiety, and enhance daytime focus and alertness.
10. Be Precise with Terminology
Use mental health terms like “OCD” and “trauma” carefully and precisely, understanding their clinical definitions. This avoids mislabeling and ensures that individuals receive appropriate understanding and treatment for their specific conditions.
11. Avoid High Glycine Dosages
Refrain from taking extremely high dosages of glycine, such as 60 grams per day, unless specifically instructed and supervised within a controlled research study. Such high amounts are not generally recommended for self-administration.
12. Explore Home Visits for OCD
If appropriate for your situation, discuss the possibility of home visits with your OCD clinician. This unique aspect of therapy allows the clinician to observe and address context-specific triggers and avoidance patterns in your natural environment.
5 Key Quotes
OCD is more like an itch that you feel, you scratch it and the itch intensifies.
Andrew Huberman
Every time that one engages in the compulsion related to the obsession, the obsession simply becomes stronger.

1 Protocols
Cognitive Behavioral Therapy (CBT) and Exposure Therapy for OCD
Dr. Helen Blair Simpson (summarizing standard procedures)- Conduct two planning sessions with the patient to describe the procedure, timing, and duration of therapy.
- Perform 15 exposure sessions, typically twice a week or more, either in-person (in vivo) with actual triggers or imaginal (imagining the trigger).
- Gradually and progressively increase the level of anxiety evoked during exposure sessions.
- Implement ritual prevention by preventing the person from engaging in their normal compulsions while experiencing heightened anxiety.
- Assign 'homework' for the patient to practice confronting anxiety and suppressing compulsions in their home environment, which often triggers relapses.
- Conduct home visits by the clinician to observe patient interactions in their native setting, identify specific anxiety-evoking locations, and pinpoint avoidance behaviors or 'crutches' used to suppress anxiety.
