What is Obsessive-Compulsive Disorder (OCD)?
Obsessive-Compulsive Disorder (OCD) is a common and highly treatable anxiety-related condition that affects children, teens, and adults. OCD involves a cycle of obsessions (distressing thoughts) and compulsions (behaviors or mental rituals) that can interfere with daily life, school, and family functioning.
Many children and adults experience occasional worries or habits—but OCD is different. A diagnosis is considered when these thoughts and behaviors:
- Take up significant time
- Cause distress, frustration, or emotional overwhelm
- Interfere with school, routines, friendships, or family life
For example, a child with OCD may have difficulty leaving the house due to rituals, repeatedly ask for reassurance, or avoid situations that trigger anxiety.
The good news is that OCD is very treatable, especially with evidence-based approaches like Cognitive Behavioral Therapy (CBT) and Exposure and Response Prevention (ERP). With the right support, children and adults can regain confidence, independence, and control over their lives.
What Are Obsessions and Compulsions?
At the core of OCD are obsessions and compulsions, which work together in a cycle that keeps anxiety going.
Obsessions are unwanted, intrusive thoughts, images, or urges that feel outside of a person’s control. These thoughts are often distressing and may cause feelings such as fear, guilt, shame, disgust, or a sense that things must feel “just right.”
Children and adults with OCD usually recognize that these thoughts don’t fully make sense—but that doesn’t stop the anxiety they cause. Over time, obsessions can become time-consuming and interfere with schoolwork, daily routines, and activities they enjoy.
It’s important to distinguish between everyday language (e.g., being “obsessed” with a hobby or show) and clinical obsessions. True obsessions disrupt functioning, rather than enhance enjoyment.
Common obsessions include:
- Fear of contamination (germs, illness)
- Fear of harm coming to self or others
- “Losing control” or acting inappropriately
- Unwanted sexual or intrusive thoughts
- Religious or moral concerns (scrupulosity)
- Need for symmetry, order, or things to feel “just right”
- Excessive doubt or need for certainty
- Superstitious or magical thinking
Compulsions are repetitive behaviors or mental acts that a person feels driven to perform in order to reduce anxiety or “neutralize” an obsession. While compulsions may provide short-term relief, they actually strengthen the OCD cycle over time, often becoming more frequent or intense.
Compulsions don’t always look obvious—avoidance (e.g., refusing to touch certain things or go to certain places) can also be a form of compulsion.
Not all repetitive behaviors are compulsions. The key difference is why the behavior is happening. Routines like bedtime habits or practicing a skill are purposeful and flexible. Compulsions, on the other hand, feel urgent, rigid, and difficult to resist.
Common compulsions include:
- Excessive washing or cleaning
- Checking (doors, locks, safety, health)
- Reassurance seeking (asking the same questions repeatedly)
- Mental rituals (counting, praying, reviewing events)
- Arranging or ordering until it feels “just right”
- Repeating actions (redoing, rereading, rewriting, or doing things in specific numbers)
Many individuals with OCD report that they don’t want to do these behaviors, but feel unable to stop because of the anxiety. This can be frustrating for both the individual and their family.
What Causes OCD?
The exact cause of Obsessive-Compulsive Disorder (OCD) is not fully understood, but research shows that it is related to a combination of brain-based, genetic, and environmental factors.
Studies suggest that OCD involves differences in how certain parts of the brain communicate with one another—particularly areas involved in decision-making, fear response, and habit formation. The neurotransmitter serotonin is believed to play an important role in this process. Both Cognitive Behavioral Therapy (CBT) and certain medications (such as SSRIs) have been shown to help regulate these brain circuits, which is why they are considered first-line treatments for OCD.
There is also a strong genetic component. OCD tends to run in families, meaning children may be more likely to develop OCD if a parent or close relative has experienced it. However, genetics alone do not determine whether someone will develop OCD.
In many cases, stressful life events, illness, or major transitions can trigger or worsen symptoms in individuals who are already vulnerable. For parents, this often looks like symptoms appearing or intensifying during periods of change (e.g., school transitions, illness, or increased stress).
What Are PANS and PANDAS?
Some children experience a sudden and dramatic onset of OCD symptoms, which may be related to medical or immune system factors. Two conditions often discussed in this context are PANS and PANDAS.
PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) is characterized by the rapid onset of OCD symptoms or severe eating restrictions, along with other changes such as:
- Increased anxiety
- Mood swings or emotional reactivity
- Irritability or oppositional behavior
- Decline in school performance
- Sleep disturbances
These symptoms are not better explained by another known medical or neurological condition.
PANDAS (Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections) is a specific subtype of PANS. It involves:
- Sudden onset of OCD symptoms and/or tics
- Typically younger age of onset
- Neurological changes (e.g., motor or behavioral symptoms)
- Symptoms that occur in connection with a strep infection (Group A Streptococcus)
For families, this often looks like a child who was previously functioning well and then abruptly develops OCD behaviors or tics “overnight.”
When Should I Seek an Evaluation for OCD?
It can be hard to know when typical worries or habits become something more. Many children go through phases of anxiety or routines—but it may be time to seek an evaluation if you notice:
- Symptoms are taking up a lot of time (e.g., rituals, reassurance, or avoidance lasting more than an hour a day)
- Your child is distressed, frustrated, or overwhelmed by their thoughts or behaviors
- Daily routines are disrupted, such as getting out the door, completing homework, or going to bed
- School is being affected, including avoidance, frequent nurse visits, or difficulty concentrating
- You are providing frequent reassurance or modifying routines to reduce your child’s anxiety
- Behaviors seem rigid or driven, rather than flexible or age-appropriate
- Symptoms appeared suddenly or escalated quickly, especially following illness or stress
Parents often describe feeling like they are “walking on eggshells,” adjusting family routines, or getting pulled into their child’s anxiety cycle. These are important signs that additional support may be helpful.
If you’re unsure, it’s always appropriate to seek a consultation early. OCD is highly treatable, and early intervention can prevent symptoms from becoming more entrenched.
What Are the Most Effective Treatments for OCD?
The most effective treatments for Obsessive-Compulsive Disorder (OCD) are Cognitive Behavioral Therapy (CBT)—specifically Exposure and Response Prevention (ERP)—and, in some cases, medication.
Exposure and Response Prevention (ERP) is the gold-standard treatment for OCD. It helps individuals gradually face the thoughts, situations, or triggers that cause anxiety (exposures) while learning to resist compulsive behaviors (response prevention). Over time, this process reduces anxiety, builds confidence, and helps the brain learn that feared outcomes are unlikely or manageable.
In some cases, a medical consultation may be recommended to provide additional support as part of a comprehensive treatment plan. Research shows that approximately 70% of individuals with OCD experience significant improvement with evidence-based therapy and/or medication.
Early, specialized treatment is key—and with the right approach, meaningful and lasting improvement is very achievable.
About Our OCD Treatment Program
At Mid Island Psychology Associates, we offer a specialized, individualized OCD treatment program designed to meet each patient’s unique needs.
The process begins with a comprehensive evaluation, where a licensed psychologist gathers information about symptoms, severity, and any co-occurring concerns (such as anxiety, depression, or autism). From there, we recommend the most appropriate level of care.
We offer:
- Traditional Outpatient Therapy
Individual sessions (typically 1–2 times per week, 45–60 minutes) focused on ERP and practical skill-building to manage OCD in daily life. - Intensive Outpatient Treatment (IOP)
A more structured option for moderate to severe OCD, where individuals work with a therapist or clinical team for multiple hours per day, across several days per week. This approach allows for more rapid progress and targeted support. Treatment intensity is tailored and adjusted based on individual needs.
Our approach is collaborative, structured, and family-inclusive, particularly for children and adolescents. We work closely with parents, schools, and other providers when appropriate to ensure consistency across environments and to support meaningful, real-world progress.
