Study Notes on Obsessive-Compulsive and Related Disorders

Classified as an anxiety disorder, but presents unique manifestations.
Patients attempt to decrease or control their anxiety through obsessive thoughts and compulsive behaviors.

Obsessions:
- Defined as recurrent, persistent, intrusive, and unwanted thoughts, images, or impulses.
Compulsions:
- Characterized as ritualistic or repetitive behaviors that individuals carry out continuously to alleviate anxiety.

Checking rituals: Activities that involve repeatedly checking things to alleviate doubts.
Touching/rubbing/tapping: Engaging in physical gestures to reduce anxiety.
Ordering:
- Includes arranging and rearranging objects to create a sense of control.
Exhibiting rigid performance:
- Performing tasks in a strict, inflexible manner.
Having aggressive urges:
- Experiencing intrusive thoughts of aggressive actions.
Counting rituals:
- Involves counting items or occurrences to relieve anxiety.
Washing/scrubbing:
- Engaging in excessive cleanliness to manage fears of contamination.
Praying/chanting:
- Repeating prayers or phrases as a method of anxiety reduction.

OCD is diagnosed when thoughts or behaviors become consuming, interfering with:
- Personal functioning
- Social interactions
- Occupational roles
Patients often recognize the irrationality of their thoughts and behaviors but feel unable to control them.

Typical onset:
- May begin in early childhood, but in females, it commonly starts in their 20s.
Symptoms can lead to periods of waxing (increasing) and waning (lessening) throughout an individual's lifetime.
Differences in onset:
- Early-onset OCD: More severe presentations and a higher likelihood of family history.
- Late-onset OCD: Varies in severity compared to early-onset type.

Self-soothing behaviors:
- Excoriation (Dermatillomania): Skin picking behavior.
- Trichotillomania: Hair-pulling disorder.
- Onychophagia: Chronic nail-biting disorder.
- Body Dysmorphic Disorder (BDD): Preoccupation with perceived flaws in physical appearance.
- Hoarding Disorder: Excessive saving behaviors leading to clutter.
Reward-seeking behaviors:
- Kleptomania: Compulsive stealing of items.
- Oniomania: Compulsive buying.
- Body Integrity Identity Disorder (BIID): Contemplation of perceiving oneself as having a disability.

Cognitive model:
- Based on Aaron Beck's cognitive approach to emotional disorders, focusing on childhood experiences and environmental factors.
Heredity:
- Complex genetic networks may contribute to hereditary risk factors for developing OCD.

OCD symptoms show relatively universal patterns globally, but expression may vary by culture.
Highly religious individuals (Christian and Muslim) may experience heightened personal guilt related to their obsessions.
Some cultures may attribute OCD symptoms to supernatural causes.
Pharmacologic treatment: Varied significantly across cultural contexts.

Medications:
- First line:
- Selective Serotonin Reuptake Inhibitors (SSRIs)
  - Examples: Fluoxetine, Fluvoxamine, Sertraline.
- Second line:
- Serotonin-Norepinephrine Reuptake Inhibitor (SNRI)
  - Example: Venlafaxine.
- For treatment-resistant OCD:
- Second-generation antipsychotics (e.g., Risperidone, Quetiapine, Aripiprazole).

Exposure Therapy:
- Involves deliberately confronting situations and stimuli that the client typically avoids.
Response Prevention:
- Focuses on delaying or preventing the performance of compulsive rituals, thereby helping individuals tolerate anxiety and reduce compulsive behaviors.

Screening Tool:
- Utilizing a screening tool for OCD to effectively measure implications for the patient (refer to Box 15.1).
Patient Assessment Scale: Key areas for assessment include:
- History:
- Examine general appearance, motor behavior (tense, anxious), and mood (overwhelming anxiety).
- Evaluate thought processes and content, identifying obsessions (e.g., contamination, religious preoccupations, self-doubt).
- Judgment and Insight:
- Patients may recognize their obsessions as irrational but feel unable to stop them.
Self-concept:
- Assess feelings of powerlessness, low self-esteem, and desires for greater willpower.
Roles and relationships:
- Examine declines in roles and interpersonal relationships.
Physiological and self-care considerations:
- Issues may include sleeping problems, changes in appetite and weight, with possible weight loss and neglect of personal hygiene noted.

Anxiety:
- A common presentation in patients with OCD.
Ineffective Coping:
- Related to difficulties in managing compulsions and obsessions.
Fatigue:
- Resulting from the stress of OCD symptoms.
Situational Low Self-Esteem:
- Related to feelings of powerlessness.
Impaired Skin Integrity:
- Related to dermatillomania (skin picking behaviors).

Interventions:
- Implement therapeutic communication and relaxation techniques.
- Utilize behavioral techniques.
- Assist in the completion of daily routines.
- Provide education to clients and families about OCD.

Educate about OCD:
- Importance of discussing obsessions and compulsions openly.
- Stress the significance of medication compliance as part of treatment.
- Behavioral techniques aimed at decreasing the intensity of OCD symptoms and effectively managing anxiety.

Avoid giving advice:
- Discourage attempts to “fix” the patient’s issues.
Be patient:
- Monitor anxiety levels among family members to assist in managing the situation.
Encourage breaks:
- Provide permission for family members to take breaks from stressful situations when needed.

Mental health professionals must recognize that clients suffering from OCD cannot simply stop their behaviors.
It is a chronic condition wherein clients are aware that their thoughts and rituals significantly interfere with their lives.
Professionals should avoid attempts to fix the patient’s issues, allowing them to seek control through appropriate treatments.
