Obsessive-Compulsive and Related Disorders: Symptoms, Diagnosis, and Differential Considerations in DSM-5-TR

This podcast episode, hosted by Dr. Donnelly Snipes, provides an in-depth review of Obsessive-Compulsive and Related Disorders as defined in the DSM-5-TR. It covers the diagnostic criteria for Obsessive-Compulsive Disorder (OCD) and Hoarding Disorder, while also touching upon Trichotillomania (hair pulling), Excoriation Disorder (skin picking), Substance-Induced OCD, and other specified conditions like olfactory reference disorder. The discussion highlights the significant increase in OCD symptoms, particularly contamination and illness-related, observed post-pandemic, contrasting it with the stable pre-pandemic prevalence rates. A key distinction is made between obsessions (intrusive thoughts, urges, images) and compulsions (repetitive behaviors or mental acts aimed at neutralizing distress or preventing dreaded events), emphasizing that a diagnosis can be made with either or both.

The episode delves into the common content themes of obsessions and compulsions, including contamination, symmetry, taboo thoughts, harm, and incompleteness. It provides specific diagnostic criteria for Hoarding Disorder, stressing the persistent difficulty in discarding possessions, the resulting cluttered living areas, and the associated distress. The concept of excessive acquisition, present in a high percentage of hoarding cases, is also introduced, alongside a nuanced discussion of animal hoarding and its potential psychological parallels to the individual's own history of neglect or abandonment. The mean age of onset for both OCD and Hoarding Disorder is identified as early to mid-adolescence, prompting consideration of developmental, biological, cognitive, and socio-emotional factors, as well as the role of trauma and superstitious reinforcement.

Dr. Snipes meticulously outlines crucial differential diagnoses to distinguish OCD and related disorders from conditions like Body Dysmorphic Disorder, Eating Disorders, Illness Anxiety Disorder, Generalized Anxiety Disorder, Major Depressive Disorder, Postpartum Depression, Substance Use Disorders, Gambling/Gaming Disorder, Schizophrenia Spectrum Disorders, Autism Spectrum Disorder, and PTSD. The overlap in symptoms, particularly between OCD and PTSD, is noted, raising questions about diagnostic specificity in self-report measures. Practical insights include the importance of focusing on presenting symptoms for individualized treatment rather than rigid diagnostic labels, and recognizing that behavior often has underlying meaning, especially in the context of trauma.

Finally, the podcast explores the fascinating connection between certain medications and the onset or exacerbation of OCD symptoms, citing atypical antipsychotics, dopaminergic agents (like L-dopa used in Parkinson's treatment), cocaine, opioids, and amphetamines. This highlights the complex interplay between neurobiology, medication, and mental health. A critical and sobering statistic shared is the high rate of suicidal ideation among individuals with OCD, with 25.9% experiencing current ideation and 44% lifetime ideation, underscoring the severity and impact of these disorders and the urgent need for effective intervention and support.

"The prevalence of obsessive-compulsive disorder in the dsm-5-tr is identified at 1.2 percent and when you look at the research up until 2019-2020 that was pretty stable and it seems to be pretty stable across cultures however when the pandemic hit post pandemic we have seen an increase in obsessive obsessive-compulsive disorder symptoms in the general population ranging between 60.3 and 62.4 percent of people in the general population."

"Obsessions are defined as recurrent and persistent thoughts urges or images that are intrusive and cause marked anxiety or distress."

"Compulsions are repetitive behaviors or mental acts people do in response to an obsession or according to rigid rules."

"Compulsions are aimed at preventing or reducing distress or preventing a dreaded event however these behaviors or mental acts are not connected in a realistic way with what they're designed to neutralize or prevent."

"Obsessions or compulsions take more than one hour per day or cause clinically significant distress or impairment in one or more areas of functioning."

"Hoarding disorder persistent difficulty parting with possessions regardless of their actual value."

"The difficulty discarding possessions results in cluttered compromised living areas."

"Remember trauma strips people's sense of safety and empowerment in what way do the the compulsions in what way does the hoarding in what way does the skin picking or hair pulling contribute to that person's sense of control and safety in their environment."

"Numerous drugs such as atypical antipsychotics which reduce dopamine and dopaminergic agents like l-dopa which increase dopamine can cause or exacerbate ocd symptoms."

"People with obsessive-compulsive disorder the current suicidal ideation rate so at any point in time the idea suicidal ideation rate of people with ocd is 25.9 so roughly 26 percent one in a little more than one in four that's a lot lifetime suicidal ideation is 44."
