Obsessive-Compulsive Disorder (OCD) is a persistent and disabling mental health disorder that affects approximately 1.2% of individuals in the United States.² Despite its frequency, OCD is frequently underdiagnosed or complicated by comorbid psychiatric conditions. Symptoms commonly emerge during adolescence or early adulthood, with an average onset age of 19.5 years, though nearly 25% of cases appear before age 14. While spontaneous remission in adulthood may occur, many individuals continue to experience substantial impairment in daily life, personal relationships, and overall well-being. Suicidal ideation affects over half of individuals with OCD, with as many as 25% attempting suicide. Prompt identification and treatment are critical for reducing the disorder’s disabling effects and improving prognosis. This course provides an in-depth overview of OCD, including clinical features, causes, diagnostic criteria, therapeutic interventions, and strategies for long-term management. It also includes nursing perspectives informed by recent research and best-practice guidelines to help healthcare professionals deliver effective care and support for individuals affected by OCD.
To understand Obsessive-Compulsive Disorder (OCD), it is important to recognize its close connection with generalized anxiety disorders (GAD), as these conditions share overlapping features.²⁰ Anxiety disorders represent a significant mental health concern characterized by excessive and persistent worry over various life domains. In the United States, approximately 0.9% of adolescents and 2.9% of adults are affected by GAD, with women being twice as likely to be diagnosed as men.² The highest prevalence of GAD occurs between the ages of 45 and 60, followed by a gradual decline in older age groups. Unlike normal, manageable worry, GAD is marked by chronic, uncontrollable anxiety that is disproportionate to the actual likelihood or consequences of feared events.⁵ Individuals with GAD often struggle to regulate their concerns, which tend to shift across multiple topics, and this mental preoccupation can significantly hinder concentration and daily functioning. In adults, common concerns include health, work, financial matters, and family, while children may worry excessively about performance or competence. Physical manifestations of GAD include restlessness, fatigue, difficulty focusing, muscle tension, irritability, and disrupted sleep patterns.
Although the exact cause of GAD is not fully understood, several contributing factors have been identified.⁵ These include:
- Environmental influences
- Genetic predisposition
- Neurobiological irregularities
- Psychological components
Research indicates a hereditary component, as those with a family history of anxiety disorders face an increased risk of developing GAD. Dysregulation in neurotransmitter systems—particularly serotonin, norepinephrine, and gamma-aminobutyric acid (GABA)—plays a central role in the pathophysiology of GAD. Neuroimaging studies have also shown both structural and functional anomalies in brain regions responsible for emotion regulation and threat detection.¹⁴ Maladaptive cognitive processes, such as persistent rumination, intolerance to uncertainty, and attentional bias toward perceived threats, can intensify and sustain anxiety. These cognitive vulnerabilities may be compounded by environmental stressors, such as traumatic experiences, chronic stress, or early life adversity. Even in the absence of a genetic predisposition, prolonged exposure to such stressors may increase susceptibility to GAD and contribute to the development of maladaptive coping mechanisms.
As outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), obsessive-compulsive disorder (OCD) is a mental health condition characterized by the presence of obsessions, compulsions, or both, which may vary in intensity and often worsen during periods of stress.² Obsessions are recurrent and intrusive thoughts, urges, or images that provoke significant anxiety or distress. These intrusive thoughts tend to follow specific thematic patterns, with the most commonly observed themes including:²
- Aggressive thoughts toward oneself or others
- Persistent doubts and uncertainty
- Fear of contamination
- Fear of losing control
- Fear of forgetting, losing, or misplacing items
- Forbidden or taboo thoughts involving sex
- Thoughts of harm
- Religious preoccupations
- A need for symmetry or exactness
Compulsions are repetitive physical behaviors or mental acts that individuals feel compelled to perform in response to their obsessions. These behaviors are aimed at reducing anxiety or preventing perceived negative outcomes, even though there is no actual connection between the compulsive act and the feared event. Importantly, compulsions provide only temporary relief and are not pleasurable. Examples include excessive handwashing due to contamination fears, repeatedly checking locks, or mentally counting in specific patterns to prevent harm. Adults with OCD may recognize the irrationality of these compulsions, while children may lack such insight and fear negative consequences if rituals are not performed.
It is crucial to differentiate between true obsessions and everyday recurring thoughts, and between compulsions and habitual behaviors.² OCD goes beyond eccentric or quirky behaviors; those affected struggle to suppress obsessions or avoid compulsions, often experiencing physiological symptoms common to anxiety disorders. The mental strain from persistent obsessions and compulsions can result in increased arousal and stress responses, such as irritability, muscle tension, difficulty focusing, and restlessness.²³ Over time, the cumulative burden of OCD may lead to fatigue and disrupted sleep. Individuals with OCD often dedicate substantial time to managing symptoms, and in severe cases, this can interfere with personal, academic, or occupational responsibilities. Some may avoid triggers altogether or turn to maladaptive coping strategies, such as substance use. For instance, someone with harm-related obsessions may withdraw from close relationships, fearing they may inadvertently hurt others, while someone obsessed with symmetry might struggle to complete tasks, resulting in poor academic or job performance. Contamination fears may also cause individuals to avoid medical environments, hindering essential healthcare access.
Obsessive-Compulsive and Related Disorders
Several disorders fall within the obsessive-compulsive spectrum and share a focus on specific obsessions or compulsive behaviors.² These include:
- Body dysmorphic disorder
- Excoriation (skin-picking) disorder
- Hoarding disorder
- OCD symptoms triggered by another medical condition
- Substance- or medication-induced OCD
- Trichotillomania (hair-pulling disorder)
Comorbidities are common in individuals with OCD. Up to 76% of those diagnosed also have an anxiety disorder, and approximately 63% have a coexisting depressive or bipolar disorder, with major depressive disorder being the most frequent, affecting 41% of cases. A significant proportion—around 30%—have a history of tic disorders, which are characterized by sudden, repetitive movements or vocalizations.²³ Motor tics may include eye blinking, shoulder shrugging, or head jerking, while vocal tics can present as grunting, sniffing, or throat-clearing.¹⁰ Tic disorders are particularly prevalent in males with early-onset OCD, and the nature of their OCD symptoms tends to differ from individuals without tic histories. It is not uncommon for individuals to have multiple coexisting conditions, such as mood and anxiety disorders. Determining whether OCD is the cause or consequence of these comorbid conditions remains a challenge.²¹
The precise etiology of obsessive-compulsive disorder (OCD) remains unclear, but growing evidence suggests that a complex interplay of genetic, neurological, environmental, and psychological influences contributes to its onset.²¹,²³ Family and twin studies strongly support the heritability of OCD, revealing a significantly higher prevalence of the disorder among first-degree relatives of those affected compared to relatives of unaffected individuals. While no single gene has been conclusively linked to OCD, the condition is believed to be polygenic, involving the combined effect of multiple genes on susceptibility.
Neuroimaging research has identified notable structural and functional differences in the brains of individuals with OCD compared to those without the disorder.²¹,²³ These studies have consistently highlighted dysfunction in the orbitofrontal cortex, anterior cingulate cortex, and striatum. The orbitofrontal cortex (OFC), located in the frontal lobes, plays a vital role in behavioral inhibition, decision-making, and reward processing. Abnormalities in this region may impair the ability to evaluate and dismiss intrusive thoughts, reinforcing compulsive behaviors. The anterior cingulate cortex (ACC) is involved in error detection, emotional regulation, and cognitive control. Altered functioning in the ACC has been associated with impaired emotional regulation and difficulty suppressing intrusive thoughts and rituals. The striatum, particularly the caudate nucleus and putamen, is a subcortical structure responsible for habit formation, reward processing, and motor control. Dysregulation within the striatum may lead to the compulsive behaviors and ritualistic actions commonly observed in individuals with OCD.
Environmental influences, particularly early life experiences, trauma, and chronic stress, also play a significant role in the development of OCD.²¹,²³ Experiences such as physical or sexual abuse, neglect, exposure to violence, or the unexpected death of a loved one can profoundly affect psychological development and coping strategies. Such events may impair the formation of adaptive emotional regulation skills and contribute to maladaptive responses, such as obsessive-compulsive behaviors. Chronic exposure to stress can also lead to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system. This dysregulation may alter neurotransmitter activity, immune function, and neuroendocrine signaling—all of which are factors implicated in OCD. Stressful life events may also increase reliance on compulsive rituals or avoidance behaviors as a method of anxiety relief and perceived control.
Certain psychological characteristics may further predispose individuals to OCD.²¹,²³ For instance, personality traits such as perfectionism, high conscientiousness, elevated anxiety, intolerance of uncertainty, and exaggerated responsibility beliefs are commonly found in individuals with obsessive-compulsive tendencies.² Those with perfectionistic traits may fixate on achieving flawless performance and fear making mistakes, prompting compulsions designed to prevent perceived failure or error. Individuals high in conscientiousness may exhibit obsessive attention to order, control, and symmetry, which can evolve into compulsive rituals aimed at maintaining structure. A low tolerance for uncertainty can lead to persistent concerns over hypothetical dangers or negative outcomes, resulting in compulsive behaviors to alleviate the discomfort of ambiguity. Finally, individuals with inflated responsibility beliefs may develop rituals in response to perceived threats, engaging in compulsions as a means to prevent imagined catastrophes. These cognitive distortions perpetuate the cycle of obsessions and compulsions and reinforce the use of maladaptive coping strategies.
Multiple risk factors have been identified as contributing to the onset of obsessive-compulsive disorder (OCD), encompassing genetic, biological, temperamental, and environmental domains.²³ Recognizing these risk factors enables healthcare professionals to pinpoint individuals at heightened risk and take proactive steps toward early intervention, potentially reducing the severity and duration of symptoms. However, the presence of one or more risk factors does not guarantee the development of OCD. The disorder is thought to result from a multifaceted interplay of various influences rather than a single cause.
A strong genetic component is evident in OCD, as individuals with a first-degree relative—such as a parent or sibling—with the disorder have a significantly elevated risk of developing it themselves. Although specific genes responsible for OCD have not yet been pinpointed, this familial link underscores a notable hereditary influence. Biological risk factors also contribute, including structural and functional abnormalities in the brain. Dysfunctional neural circuits, especially those involving the orbitofrontal cortex, anterior cingulate cortex, and striatum, have been associated with OCD. Imbalances in key neurotransmitters—particularly serotonin and dopamine—may further exacerbate susceptibility. Additionally, congenital anomalies, localized brain lesions, or a history of traumatic brain injury affecting these regions may increase vulnerability to OCD.
Temperamental characteristics evident in early childhood may also increase the likelihood of developing OCD. Children who display inhibited behavior, high levels of anxiety, perfectionistic tendencies, or persistent negative emotions are considered at higher risk. These personality traits may interact with other risk factors and contribute to maladaptive responses under stress, setting the stage for the development of OCD symptoms later in life. Comorbid psychiatric conditions also elevate risk. Individuals diagnosed with mood disorders such as depression, other anxiety disorders, or tic disorders including Tourette syndrome are more likely to experience OCD. The overlap in symptoms and neurobiological mechanisms between these conditions suggests shared pathways that may contribute to their co-occurrence.
Environmental stressors, particularly those encountered in early life, are significant contributors to OCD risk. Traumatic experiences in childhood—including physical, emotional, or sexual abuse; neglect; or prolonged exposure to instability—can impair emotional regulation and increase the likelihood of developing OCD. Stressful life changes or transitions, such as relocation, job changes, or the breakdown of significant relationships, may act as catalysts, triggering or intensifying OCD symptoms in predisposed individuals. These environmental influences often interact with genetic, biological, and temperamental vulnerabilities, highlighting the complex and multifactorial nature of OCD development.
Diagnosing obsessive-compulsive disorder (OCD) requires confirming the presence of obsessions, compulsions, or both, in alignment with five specific criteria established by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)²:
- Obsessions and compulsions are time-consuming, often taking up more than one hour per day, and significantly interfere with the individual’s daily functioning.
- Obsessions are intrusive, unwanted, and distressing, prompting the individual to attempt to suppress or neutralize them through compulsions.
- Compulsions are repetitive behaviors or mental acts aimed at preventing or reducing distress or a feared event, but they are not realistically connected to the intended outcome.
- Symptoms are not attributable to substance use or medication, ensuring the behaviors are not a side effect of drugs or medical treatment.
- Symptoms are not better explained by another mental or medical disorder, such as schizophrenia, autism spectrum disorder, or body dysmorphic disorder.
In children, diagnosis is often centered on compulsions, as they are easier to observe, and children may struggle to verbalize their obsessions. Symptom patterns may vary with age. Adolescents more commonly report religious or sexual obsessions, while children are more likely to express fears of harm or catastrophic events involving themselves or loved ones.
A critical component in OCD diagnosis involves evaluating insight—how well the individual understands the irrational nature of their symptoms.² Insight may vary:
- Good or fair insight: The person recognizes that their beliefs are probably not true but still feels compelled to act on them.
- Poor insight: The individual believes the obsessive fears are likely true, despite evidence to the contrary.
- Absent insight/delusional beliefs: The person holds firm convictions that their obsessive fears are entirely accurate and logical, without recognizing their irrationality.
This spectrum of insight can fluctuate over time and has implications for treatment planning and prognosis.
Differential Diagnosis
Differentiating OCD from similar mental health conditions is essential to avoid misdiagnosis and ensure appropriate care.² Commonly overlapping conditions include:
- Anxiety disorders: These may include repetitive behaviors like reassurance-seeking or avoidance, but they are generally centered on realistic concerns and do not involve compulsions.
- Specific phobias: These are narrowly focused fears, typically triggered by specific stimuli, whereas OCD-related fears are more persistent and wide-ranging.
- Major depressive disorder (MDD): MDD involves negative thought patterns, but these are not linked to compulsions or efforts to neutralize specific obsessions.¹²
- Eating disorders: Conditions like anorexia nervosa may include obsession-like concerns about food and body image, but they lack the broader thematic scope of OCD.¹⁷
- Tic disorders and stereotyped movements: Tics are brief, sudden, and repetitive motor or vocal actions not aimed at reducing anxiety. They are typically preceded by sensory urges, unlike compulsions, which follow obsessive thoughts.⁸
- Psychotic disorders: Conditions such as schizophrenia or schizoaffective disorder may involve irrational beliefs and hallucinations but lack the structured obsessions and compulsions seen in OCD.¹⁵
- Impulse-control disorders: Behaviors like compulsive gambling or hypersexuality may resemble compulsions but are driven by pleasure-seeking rather than anxiety reduction. These behaviors are typically resisted only because of their negative consequences.
- Obsessive-compulsive personality disorder (OCPD): Despite the similar name, OCPD is characterized by rigidity, perfectionism, and control, not by intrusive thoughts or ritualistic behaviors. It lacks the hallmark obsessions and compulsions found in OCD.
Treatment options for obsessive-compulsive disorder (OCD) are available across a range of severity levels and can provide significant relief from the distressing symptoms of the condition.²¹ ²³ While OCD cannot be cured, various interventions—such as psychotherapy, brain stimulation, medication, or a combination of these—can improve functioning and enhance quality of life.
Psychotherapy
Two specific types of psychotherapy have demonstrated effectiveness in treating OCD: cognitive behavioral therapy (CBT) and exposure and response prevention therapy (ERP). CBT is widely recognized as the “gold standard” and is used for both children and adults with mild to severe OCD.²² CBT focuses on the cognitive (thought-based) and behavioral components of the disorder. Through cognitive restructuring, individuals learn to identify distorted thoughts, assess their validity, and replace them with more realistic beliefs. For example, a person afraid of contamination from touching doorknobs may, through CBT, recognize that the perceived threat is minimal.
CBT also includes practical strategies such as:
- Thought stopping, where individuals interrupt obsessive thought patterns by mentally saying “stop” or redirecting their attention.
- Response prevention, which teaches tolerance of obsessive discomfort without acting on compulsions.
- Behavioral experimentation, which involves testing irrational fears by facing triggers without resorting to compulsions, helping reduce anxiety over time.
ERP, a specialized form of CBT, is particularly useful for those who do not respond to medications alone.⁹ In ERP, patients are gradually exposed to stimuli that trigger obsessive thoughts while being prevented from performing compulsions. For instance, someone with contamination fears may be encouraged to touch a dirty object and refrain from washing their hands. Repeated exposure reduces anxiety and decreases the frequency of compulsive behaviors. Though initially challenging, ERP helps individuals regain control and diminish OCD symptoms over time.
Brain Stimulation
Two brain stimulation techniques are used to treat severe cases of OCD:
- Repetitive transcranial magnetic stimulation (rTMS)
rTMS is a non-invasive procedure that uses magnetic pulses to stimulate targeted areas of the brain.¹ Approved by the FDA in 2018 for treatment-resistant OCD, rTMS modulates activity in brain regions such as the prefrontal cortex. It is often combined with psychotherapy and medication for enhanced outcomes. - Deep brain stimulation (DBS)
DBS is a surgical procedure involving implanted electrodes that send electrical impulses to brain regions involved in OCD, such as the internal capsule or nucleus accumbens.¹¹ While DBS is FDA-approved for certain neurological conditions, its use for OCD remains under investigation.¹⁹ Under a Humanitarian Device Exemption, DBS may be used in individuals with severe, treatment-resistant OCD who have not improved with other options.⁶ Though promising, DBS is invasive and carries risks, and research is ongoing to assess its long-term efficacy and safety.
Medication
The primary medications used to manage OCD symptoms include selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs).²³ SSRIs, such as fluoxetine, sertraline, and fluvoxamine, are the first-line treatment.¹⁶ These medications increase serotonin levels, which help regulate mood, anxiety, and obsessive thoughts. When SSRIs are not effective or not tolerated, TCAs such as clomipramine and imipramine may be prescribed. These medications also elevate serotonin and norepinephrine levels, contributing to reduced OCD symptoms.
Antidepressants often take up to 12 weeks to begin showing benefits, and optimal improvement may take six months. Approximately 60% of individuals experience some relief from their first course of antidepressants, but fewer than 20% achieve full remission with medication alone.¹⁶ Medications tend to be more effective when combined with psychotherapy.
Side effects are more common in OCD treatment due to the higher doses of antidepressants required. These may include nervousness, insomnia, nausea, dizziness, restlessness, and diarrhea. These symptoms often diminish as the body adjusts over time.
Additional medications include:
- Low-dose neuroleptics (antipsychotics) for individuals with OCD and coexisting tic disorders.
- Glutamate modulators such as memantine, ketamine, and glycine, which may help regulate glutamate activity—a neurotransmitter thought to play a role in OCD. Further research is needed to confirm their efficacy.
Once OCD symptoms are significantly reduced following an initial course of treatment, long-term management focuses on maintaining progress and preventing relapse.⁴ Because OCD is a chronic disorder prone to recurrence, healthcare providers recommend follow-up visits at least once a month for the first six months post-treatment. Ongoing care should continue for at least a year before considering the tapering or cessation of medications or therapy. Consistent monitoring helps assess symptom severity, level of insight, and functional status, enabling early intervention if signs of relapse appear. For most individuals, continuing psychotherapy—whether in individual or group settings—remains beneficial. These sessions reinforce coping strategies, maintain treatment gains, and address lingering symptoms or triggers.
Long-term management may also require medication adjustments.¹⁸ If individuals experience significant symptom improvement or reach stable remission, providers may consider gradually discontinuing medication. The standard tapering protocol involves reducing the dose by 25% at a time, with two-month intervals to observe patient response before further reduction. This cautious approach minimizes the risk of relapse and ensures symptoms are closely monitored. However, individuals with frequent OCD relapses—such as two to four severe episodes or three to four milder ones—may require prolonged or lifelong medication to maintain stability and reduce exacerbations.
A healthy lifestyle plays a key role in sustaining long-term mental well-being.⁷ Regular physical activity can lessen anxiety and depressive symptoms that commonly co-occur with OCD. Ensuring adequate sleep is crucial, as poor sleep can heighten OCD symptoms. Stress reduction techniques—such as deep breathing, mindfulness meditation, and relaxation exercises—help mitigate emotional distress. A nutritious diet supports brain health and emotional regulation. Additionally, engaging in meaningful hobbies and maintaining social relationships provide fulfillment and distraction from obsessive thoughts. These positive outlets help reduce compulsive behaviors and promote overall quality of life. Emotional support from family, friends, and support groups is especially helpful for those navigating ongoing OCD challenges.
For children with OCD, family involvement is vital for effective long-term management.²¹ ²³ Parents and caregivers are encouraged to take an active role in therapy, reinforce behavioral strategies at home, ensure adherence to medication regimens, and provide emotional support. Helping children build healthy habits—such as consistent exercise, sleep, and nutrition—supports mental wellness. Collaboration with school staff ensures children receive appropriate accommodations, such as extended time on tasks, modified assignments, or access to counseling. Since children’s symptoms and needs can change frequently, treatment plans should be flexible and regularly re-evaluated by healthcare providers to ensure optimal symptom control and support.
When providing care to individuals diagnosed with OCD, nurses serve a pivotal role in ensuring effective management. A holistic assessment is essential, encompassing the patient’s physical, psychological, social, and environmental status.¹³ Nurses should begin by evaluating the patient’s physical health and identifying any existing medical conditions or medications that could influence OCD symptoms or interfere with treatment. This includes a focused assessment of the type, severity, and impact of obsessions and compulsions, as well as the level of insight the patient has regarding their condition. Concurrent mental health issues—such as anxiety, depression, or other psychiatric disorders—should also be assessed to provide integrated care. In addition, understanding the patient’s social support network, including relationships and home environment, can help reveal stressors or triggers that may aggravate OCD symptoms. Evaluating functional impairments—such as difficulties in daily tasks, work performance, academic responsibilities, and social engagement—further informs treatment planning and goal-setting.
Cultural sensitivity is crucial when assessing and planning care. Patients’ cultural backgrounds, beliefs, and values may shape their perceptions of OCD and influence their willingness to seek treatment or adhere to recommendations. Nurses must document all assessments thoroughly and accurately to ensure continuity of care. Establishing a therapeutic alliance with the patient is also a core nursing responsibility. Demonstrating empathy, active listening, and emotional validation encourages open communication.²¹ ²³ Patients with OCD may feel guilt or shame about their symptoms; therefore, nurses must maintain a compassionate, nonjudgmental stance that fosters a supportive environment and reinforces the message that OCD is a medical condition, not a personal failure.
Education plays a central role in empowering both patients and their families.¹³ Nurses should explain the nature of obsessions and compulsions, and how they interfere with everyday life. Educating families about the genetic, biological, environmental, and psychological factors that contribute to OCD helps demystify the condition and may alleviate misplaced guilt or stigma. Nurses must also provide detailed information about treatment options, including medications like selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, and adjunctive agents. The effectiveness and mechanisms of cognitive behavioral therapy (CBT) and exposure and response prevention (ERP) should also be discussed, emphasizing how these therapies help individuals manage symptoms and reduce distress over time.
During treatment, nurses are responsible for administering prescribed medications and monitoring for adverse reactions or side effects to ensure patient safety and efficacy.²⁴ Patient and family education should underscore the importance of adhering to the prescribed treatment plan and address any misconceptions or fears about therapy or medications. In times of crisis or severe distress, nurses are key to providing emotional support and implementing de-escalation strategies. They help patients manage acute symptoms, reduce anxiety, and prevent self-harm or harm to others by creating a calming and safe environment.
Ongoing monitoring is vital to track the patient’s response to treatment and adjust interventions as needed. Nurses must assess the effectiveness of both pharmacological and non-pharmacological approaches and document observations, treatments, and outcomes meticulously in the medical record. Accurate documentation ensures that the entire healthcare team is informed and aligned in delivering coordinated, effective care.
Obsessive compulsive disorder (OCD) is a multifaceted psychiatric condition shaped by genetic, biological, temperamental, and environmental factors. It impacts individuals across diverse populations, often disrupting daily functioning and diminishing quality of life. Due to its symptom overlap with other psychiatric disorders, precise diagnosis and differentiation are critical for establishing an effective treatment plan. Although OCD is not curable, a range of therapeutic options—including psychotherapy, pharmacological interventions, and brain stimulation therapies—can significantly reduce symptom burden and enhance functioning when used independently or in combination.
Ongoing management is essential for sustaining improvements made during active treatment and minimizing the risk of relapse. This requires routine monitoring, flexible treatment adjustments, and support in adopting lifestyle practices that contribute to long-term mental health. Nurses are integral to the care of individuals with OCD, conducting thorough assessments, educating patients and families, administering treatments, responding to crises, and collaborating with interdisciplinary teams. Through a comprehensive, multidimensional approach that integrates biological, psychological, social, and environmental considerations, healthcare professionals can support individuals with OCD in achieving symptom control, maintaining functional stability, and improving their overall quality of life.
