    Study Notes

    • Characterized by obsessions and/or compulsions.
    • Obsessions are intrusive, unwanted thoughts, urges, or images.
    • Compulsions are repetitive behaviors or mental acts performed in response to obsessions.
    • The DSM-5 groups these disorders due to their relatedness.
    • Clinicians should screen for these conditions in individuals presenting with one of them.
    • Important differences exist in diagnostic validators and treatment approaches across these disorders.

    Obsessive-Compulsive Disorder (OCD)

    • Individuals have varying degrees of insight into the accuracy of their beliefs.
    • Up to 30% of individuals with OCD have a lifetime tic disorder.
    • Most individuals with OCD have both obsessions and compulsions, typically related.
    • Common themes: cleaning, symmetry, forbidden thoughts, harm.
    • 1.2% prevalence in the United States.
    • Women affected at a higher rate than men in adulthood, but men are more common in childhood.
    • Mean age of onset is 19.5 years, with 25% of cases starting by age 14.
    • Course is usually chronic, often waxing and waning.
    • Remission rates are low without treatment.
    • Treatmental risk factors include internalizing symptoms, negative emotionality, and behavioral inhibition.
    • Twin studies suggest additive genetic effects account for 40% of the variance in obsessive-compulsive symptoms.
    • OCD affects individuals worldwide, with differences in gender distribution, age of onset, and comorbidity.
    • Men have an earlier age of onset than women, often in childhood, and more likely to have comorbid tic disorders.
    • Gender differences in symptom dimensions exist.
    • Onset or exacerbation of OCD reported in the peripartum period.
    • A systematic literature review found a mean rate of lifetime suicide attempts of 14.2% in individuals with OCD.
    • Predictors of suicide risk include severity of OCD, unacceptable thoughts, comorbid depression and anxiety symptoms, and past suicidality.
    • OCD needs to be distinguished from:
      • Generalized anxiety disorder (worries).
      • Specific phobia.
      • Social anxiety disorder.
      • Major depressive disorder.
      • Body dysmorphic disorder.
      • Trichotillomania.
      • Hoarding disorder.
      • Anorexia nervosa.
      • Tic disorders.
      • Delusional disorder.
      • Obsessive-compulsive personality disorder.
    • Comorbidity is common in individuals with OCD.
    • Onset of OCD is usually later than most comorbid anxiety disorders and PTSD, but often precedes depressive disorders.

    Body Dysmorphic Disorder (BDD)

    • Preoccupation with perceived defects or flaws in physical appearance.
    • Flaws are not observable or appear slight to others.
    • Muscle dysmorphia is a form of BDD that occurs almost exclusively in men and adolescent boys.
    • Individuals with BDD vary in their degree of insight.
    • BDD is characterized by intrusive, unwanted, time-consuming, and difficult to resist behaviors.
    • Must be differentiated from an eating disorder.
    • Individuals with BDD have high levels of anxiety, social anxiety, social avoidance, depression, perfectionism, low self-esteem, and are ashamed of their appearance.
    • BDD often responds poorly to cosmetic treatment and may become worse.
    • BDD has been associated with abnormalities in emotion recognition, attention, executive function, information-processing biases, and inaccuracies in interpretation of information and social situations.
    • Prevalence higher in girls/young women than boys/young men.
    • Mean age at onset 16-17 years.
    • Subclinical symptoms begin at age 12 or 13 years.
    • Disorder appears to be chronic.
    • The clinical features appear largely similar in children/adolescents and adults.
    • Risk and prognostic factors include childhood neglect, abuse, trauma, and elevated rates of teasing.
    • Elevated in first-degree relatives of individuals with OCD.
    • Heritability estimated at 37%–49% in studies of adolescent and young adult twins.

    Body Dysmorphic Disorder

    • Body dysmorphic disorder (BDD) involves excessive preoccupations with perceived flaws in physical appearance.
    • These preoccupations lead to repetitive behaviors like mirror checking, skin picking, or excessive grooming.
    • BDD significantly impacts an individual's social, occupational, and personal life.
    • The disorder is characterized by intense distress, impairment of functioning, and difficulty resisting the compulsions.
    • Individuals with BDD are at an increased risk for suicidal thoughts and behaviors.
    • The severity of BDD symptoms is directly linked to the likelihood of suicidal ideation and attempts.
    • BDD often co-occurs with other mental health disorders, like substance use disorder in men and eating disorders in women.
    • Comorbidities may include major depressive disorder, anxiety disorders, and obsessive-compulsive disorder (OCD).
    • BDD can lead to physical complications such as skin lesions from picking, scarring, and social isolation.
    • Differentiation from other disorders is crucial:
      • Appearance concerns are considered a symptom of an eating disorder, not BDD, unless they are independent anxieties about specific body parts.
      • BDD focuses solely on appearance flaws, while OCD compulsions may involve a wider range of obsessions.
      • Skin picking for cosmetic reasons is considered BDD, unlike skin-picking disorder, where the picking is driven by a need to relieve tension.
      • Hair pulling for appearance reasons falls under BDD, whereas trichotillomania involves compulsive hair pulling independent of appearance concerns.

    Hoarding Disorder

    • Hoarding disorder is characterized by an inability to discard possessions, regardless of their actual value.
    • The hoarding behavior stems from a perceived need to save the items and the distress associated with discarding them.
    • The accumulation of possessions leads to clutter and congestion of living spaces, making them unusable.
    • Individuals with hoarding disorder experience significant distress and impairment in social, occupational, and other areas of life.
    • Hoarding behavior is not a symptom of other medical conditions or mental disorders.
    • Hoarding symptoms can include excessive acquisition, particularly through buying and accepting free items.
    • Individuals with hoarding disorder often experience distress if they cannot acquire items.
    • Hoarding disorder is distinguished from normal collecting behavior by the unorganized and excessive accumulation of possessions.
    • While the primary feature is the inability to discard, hoarding disorder can also include excessive acquisition of possessions.
    • Hoarding disorder can significantly impair basic activities like moving, cleaning, and personal hygiene.
    • The disorder can lead to physical risks such as fire hazards, falls, sanitation issues, and health complications.
    • Hoarding disorder is associated with occupational impairment, poor physical health, and increased social service utilization.
    • It can strain family relationships and lead to conflicts with neighbors and local authorities.
    • The presence of hoarding behavior is not considered a diagnosis if it is a direct consequence of another medical condition, such as brain damage, cerebrovascular disease, or neurodevelopmental disorders.
    • Hoarding disorder often co-occurs with other mental health disorders, particularly mood and anxiety disorders.

    Trichotillomania (Hair-Pulling Disorder)

    • Trichotillomania is characterized by recurrent hair pulling resulting in hair loss.
    • Significant hair pulling can occur in brief episodes or more sustained periods lasting for hours, months, or even years.
    • The disorder involves the pulling of hair from any body part, including the scalp, eyebrows, eyelids, and other regions.
    • Trichotillomania is often associated with rituals involving hair manipulation after pulling.
    • Hair pulling may be preceded or accompanied by various emotional states, such as anxiety, tension, or relief.
    • The disorder can present varying degrees of conscious awareness, ranging from focused attention to automatic behavior.
    • Hair pulling usually does not occur in front of others, except immediate family members.
    • Some individuals may pull hair from pets, dolls, or other fibrous materials.
    • Trichotillomania is more common in women than men, but the gender ratio may be closer in community samples.
    • The disorder is more common in individuals with OCD and their first-degree relatives than in the general population.
    • Trichotillomania can lead to social and occupational impairment and irreversible damage to hair growth.
    • Medical consequences include digit purpura, musculoskeletal injury, blepharitis, dental damage, and trichobezoars, which can lead to more severe complications.
    • Differentiation from other disorders:
      • Hair removal for cosmetic reasons is not considered trichotillomania.
      • Hair pulling in OCD is part of a larger ritual, whereas trichotillomania involves hair pulling as the primary compulsion.
      • Hair pulling in body dysmorphic disorder is driven by concerns about appearance, not a general compulsion.
      • Trichotillomania is not diagnosed if the hair pulling is a symptom of another medical condition.
    • Trichotillomania often co-occurs with other mental health disorders, particularly major depressive disorder and excoriation (skin-picking) disorder.

    Excoriation (Skin-Picking) Disorder

    • Excoriation (skin-picking) disorder is characterized by repeated picking at one's skin, resulting in skin lesions.
    • The skin picking often occurs on the face, arms, and hands, but individuals can pick from multiple body sites.
    • Skin picking can be accompanied by various behaviors and rituals related to the skin, such as examining scabs or manipulating the skin after picking.
    • Skin picking may be preceded by various emotional states, such as anxiety, tension, or relief.
    • Individuals with skin picking disorder may engage in focused or automatic skin picking.
    • Skin picking is usually done in private, although some individuals may report picking others' skin.
    • The disorder is more common in women than men.
    • The onset usually occurs during adolescence, coinciding with or following puberty.
    • Skin picking often begins with a dermatological condition, such as acne.
    • The disorder is usually chronic with periods of waxing and waning.
    • There is evidence for a genetic vulnerability to excoriation disorder, and it is more common in individuals with OCD and their first-degree family members.
    • Excoriation disorder can lead to social and occupational impairment as well as medical complications such as tissue damage, scarring, and infection.
    • The disorder can require antibiotic treatment and surgery.
    • Differentiation from other disorders:
      • Skin picking in psychotic disorders is driven by delusions or hallucinations.
      • Skin picking in OCD is a compulsion to relieve anxiety.
      • Skin picking in body dysmorphic disorder is driven by concerns about appearance.
    • Excoriation disorder often co-occurs with other mental health disorders, particularly major depressive disorder and trichotillomania.### Stereotypic Movement Disorder
    • Repetitive self-injurious behavior may be a characteristic of Stereotypic Movement Disorder
    • Onset of Stereotypic Movement Disorder is in the early developmental period

    Dermatitis Artefacta

    • Also known as "factitious dermatitis"
    • Medically unexplained skin lesions
    • Individuals deny involvement in creating these lesions

    Excoriation Disorder

    • If there is evidence of deception concerning skin lesions, Excoriation Disorder may be diagnosed as malingering or factitious disorder
    • A diagnosis of Excoriation Disorder is not made when skin picking is primarily due to another medical condition, such as scabies or acne excoriée
    • Diagnosis based on presence or absence of comorbid substance use disorder
    • Obsessions, compulsions, skin picking, hair pulling, other body-focused behaviors, or other symptoms characteristic of the disorder are criteria
    • ICD-10-CM codes are used to indicate these disorders
    • If a mild substance use disorder is comorbid with the substance-induced obsessive-compulsive and related disorder, record "mild [substance] use disorder"
    • If a moderate or severe substance use disorder is comorbid with the substance-induced obsessive-compulsive and related disorder, record "moderate [substance] use disorder" or "severe [substance] use disorder"
    • If no comorbid substance use disorder, only the substance-induced obsessive-compulsive and related disorder is recorded
    • The name of the substance/medication-induced obsessive-compulsive and related disorder begins with the specific substance (e.g., cocaine)
    • The diagnostic code is selected from a drug class and presence or absence of comorbid substance use disorder
    • If the specific class of substance is unknown, the code for "other (or unknown) substance" should be used
    • The comorbid substance use disorder (if any) is listed first, followed by "with substance/medication-induced obsessive-compulsive and related disorder" (incorporating the name of the specific etiological substance/medication), followed by the specification of onset
    • Each substance playing a significant role in the development of the disorder should be listed separately
    • Clinically significant obsessive-compulsive and related symptoms directly related to another medical condition
    • Obsessions, compulsions, preoccupations with appearance, hoarding, skin picking, hair pulling, or other body-focused repetitive behaviours are included
    • Evidence from the history, physical examination, or laboratory findings is necessary for diagnosis

    PANDAS

    • Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS)
    • Sudden onset of obsessions, compulsions, and/or tics
    • Associated with Group A streptococcal infection
    • Absence of chorea, carditis, or arthritis

    PANS

    • Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANS)
    • Abrupt, dramatic onset of obsessive-compulsive symptoms
    • Severely restricted food intake
    • Range of additional neuropsychiatric symptoms
    • Assessment guidelines are available

    Obsessive-Compulsive Spectrum Disorders (OCSDs)

    • Mental disorders shared similar psychological attributes, including anxiety, self-injury, and body-focused, tension-releasing behaviors

    • May have important implications for an individual's level of functioning and for selecting the most effective intervention.

    • Significant time disruption, but clinical presentations vary markedly

    • Disorders can be highly researched or less researched but no less disabling

    • Shared features between disorders in this spectrum include:

      • Phenomenological
      • Psychological
      • Biological

    • Shared genetic similarities, associated traits such as harm avoidance, prevalence of specific personality disorders, and response to the same types of drugs

    • Disorders included in this spectrum:

      • Trichotillomania
      • Obsessive-compulsive disorder
      • Becoming obsessed with appearance and body
      • Anorexia nervosa
      • Kleptomania
      • Various phobias
      • Impulsive shoplifting

      Anxiety And Obsessive-Compulsive Spectrum

    • Anxiety is an integral part of the obsessive-compulsive spectrum

    • Differences between disorders within the obsessive-compulsive spectrum can be explained in terms of the relationship between anxiety and obsessive-compulsive behaviors

    • Anxiety understood as an exaggerated threat-detection system

    • Relationship between panic disorder, generalized anxiety disorder, and OCD

    • In the specific case of OCD, anxiety is an underlying or accompanying aspect of the disorder

    • Concrete limitations and the dysfunction caused by the ritual of compulsion inherently generate anxiety as a product

    • Anxiety is also present in both the triggers of obsessions and the triggers of rituals

    • Alternative explanation model suggests that obsessive thoughts gain an emotional response directly from the cognitive interpretation of the obsession, as well as an automatic emotional response stemming from the way in which the obsession is perceived

    • This second emotional response is what causes or triggers the habitual ritual

    • The problems caused by the actual compulsion or obsession generate anxiety as a reaction that generates a compulsion or obsession

    • Shared conditions between anxiety and OCD, which include many bodily sensations, thoughts, and avoidance behaviors

    Trichotillomania

    • A form of impulse-control disorder
    • Can be considered an obsessive-compulsive disorder
    • Habitual pulling out of one's own hair
    • Often on the scalp
    • Can also affect eyelashes, face, and other parts of the body
    • Common symptoms
      • Itching
      • A tingling sensation before hair is pulled
    • Afflicts between 2 to 4 percent of the population in the United States
    • Studies are trying to understand the causes:
      • Biological disorder
      • A result of family dynamics or psychological stress
      • Combination of genetic factors and environmental stress

    Obsessive-Compulsive Disorder (OCD)

    • A chronic, burdensome brain disorder
    • Falls under major anxiety conditions
    • Relationship between OCD and anxiety is bidirectional, with various anxiety disorders having inappropriate levels of worry or emotional distress for non-dangerous situations
    • OCD often presents alongside these anxiety problems, with the mixing of obsessions and worries being common
    • The two disorders share several best-guess etiological connections, with a genetic diathesis making for enhanced sensitivity to commonplace environmental inputs and possibly a more direct approach to the problems
    • Psychopharmacological and various forms of psychotherapy management look very different across these conditions, but adequate assessment for the problems and changes in each needs to be a cornerstone of treatment management strategies
    • The overlap between anxiety problems and OCD in topics, symptoms, cognitive styles, genetics, and treatment issues has led some to conclude that these two problems are no different from one another.
    • Another interpretation is that the experience of the clinical picture of type A anxiety disorder could produce behavior change in domains besides the development of emotional responses at a high level.
    • Symptoms characteristic of an obsessive-compulsive and related disorder that cause clinically significant distress
    • Impairment in social, occupational, or other important areas of functioning
    • Do not meet the full criteria for any of the disorders in the diagnostic class
    • Examples of presentations that can be specified using the "other specified" designation include:
      • Body dysmorphic-like disorder with actual flaws
      • Body dysmorphic-like disorder without repetitive behaviors
      • Other body-focused repetitive behavior disorder
      • Obsessional jealousy
      • Olfactory reference disorder
      • Shubo-kyofu
      • Koro

    Body Dysmorphic-Like Disorder With Actual Flaws

    • Similar to body dysmorphic disorder, but with more noticeable defects or flaws in physical appearance

    Body Dysmorphic-Like Disorder Without Repetitive Behaviors

    • Similar to body dysmorphic disorder, but without repetitive behaviors or mental acts
    • Response to appearance concerns

    Other Body-Focused Repetitive Behavior Disorder

    • Recurrent body-focused repetitive behaviors
    • Other than hair pulling and skin picking
    • Accompanied by repeated attempts to decrease or stop the behaviors

    Obsessional Jealousy

    • Non-delusional preoccupation with a partner's perceived infidelity
    • Leading to repetitive behaviors or mental acts in response to infidelity concerns

    Olfactory Reference Disorder

    • Persistent preoccupation with the belief that they emit a foul or offensive body odor
    • Unnoticeable to others or only slightly noticeable

    Shubo-Kyofu

    • Variant of taijin kyofusho
    • Similar to body dysmorphic disorder
    • Excessive fear of having a bodily deformity

    Koro

    • Related to dhat syndrome

    • Sudden and intense anxiety that the penis in males or the vulva and nipples in females will recede into the body

    • Possibly leading to death### Intrusive Thoughts

    • Intrusive thoughts are common and often fall into a similar format.

    • People may try to suppress these thoughts, which can actually increase their frequency.

    • Worrying about or suppressing intrusive thoughts can worsen anxiety.

    • Intrusive thoughts are experienced as frightening, uncontrollable, and unwanted.

    • Differentiating between normal worries and clinical obsessions is crucial.

    • The intensity, frequency, and duration of intrusive thoughts help distinguish them from normal worries.

    • Dwelling on obsessive preoccupations can prevent solving or coping with them.

    Gambling Disorder (GD)

    • GD is considered an addictive behavior within the obsessive-compulsive spectrum disorders (OCSD).
    • A core symptom of GD is preoccupation with gambling.
    • People with GD often seek relief and relaxation through gambling, not from a fantasy world.
    • The adrenaline rush from gambling is short-lived, followed by a crash.
    • People with GD often experience emotions of loss, such as helplessness, impatience, and anxiety.
    • The main motivation behind GD is not the rush, but the reduction of negative emotions.
    • People with GD have a higher risk of comorbid psychiatric disorders, including infectious diseases and chemical dependencies.
    • GD is associated with a higher likelihood of physical trauma symptoms related to post-traumatic stress disorder.

    Treatment of GD

    • Existing pharmacological treatments for GD are not the first choice due to side effects, inconsistent efficacy, and comorbid conditions.
    • Treatment options for GD should consider the neurobiological and psychological factors.
    • Books and chapters are needed to educate clinicians about the brain mechanisms underlying GD.

    Obsessive-Compulsive Spectrum Disorders (OCCDs)

    • Compulsive checking and cleaning are common manifestations of OCCDs, which are linked to serotonin pathway disturbances.
    • Imaging studies show disarray in brain structures like the medial cortex and hippocampus, leading to excessive checking behavior.
    • Cognitive distortions often contribute to checking behaviors.
    • The preferred treatment for OCCDs involves behavioral therapy that confronts the patient with triggering situations.

    Insight in OCD Spectrum Disorders

    • Understanding a patient's mental representation and consciousness is crucial for clinical practice.
    • Poor insight is related to non-compliance with treatment.
    • Assessing insight in patients with OCD is both practical and empirical.
    • Enhanced insight is a key element of successful therapy, along with self-awareness and behavioral changes.
    • A staged approach is recommended for assessing a patient's understanding of their treatment.
    • Longitudinal assessments are important to monitor changes and guide therapy strategies.
    • Insight scores are strongly associated with symptom severity.
