Have you ever checked your door lock so many times that you nearly missed your bus, or washed your hands long after you stopped worrying about germs, and thought, "Am I just too anxious?" Those actions and persistent, bothersome thoughts might not just be unusual habits. They could indicate Obsessive-Compulsive Disorder (OCD), a condition that is one of the most challenging mental health issues but is often misdiagnosed. Why does this occur? One reason is that OCD used to be classified alongside anxiety disorders, and its signs are similar to those of various other issues, like ADHD, behaviors focused on the body, or even depression. Additionally, cultural norms that discourage sharing intrusive thoughts can make it easy for a doctor to overlook it. To clarify everything, let's thoroughly explore what OCD truly is (according to DSM-5), examine how its signs overlap with other conditions, understand why misdiagnosis is common, and provide useful tips for ensuring a correct diagnosis.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), describes OCD as having obsessions (persistent, unwanted thoughts, urges, or images that lead to considerable anxiety) and/or compulsions (repetitive actions or mental activities done to alleviate the anxiety from those obsessions), which consume time or cause significant distress or dysfunction. Simply put, imagine it as an anxiety cycle: obsessive worry leads to a repeated behavior, such as checking or cleaning, that gives temporary relief from anxiety but actually strengthens the cycle.

Symptoms And Types Of OCD:

OCD symptoms usually include:

Obsessions: such as fears of germs, needing things to be in a certain order, concerns about causing harm, inappropriate thoughts, or unwelcome images.
Compulsions: like washing hands, checking things, organizing, counting, or mental rituals such as praying or looking for reassurance.

OCD comes in different types, including:

Washing due to fear of contamination
Checking for harm
Obsessive thoughts without visible compulsions
Need for symmetry or order
Hoarding (which is now classified as a separate diagnosis in DSM-5).

Why OCD Symptoms Overlap With Other Disorders?

Here is where it becomes complicated. Since many mental health issues share similar signs, OCD is frequently confused with several other disorders.

ADHD can look like OCD: both can lead to excessive organizing or trouble paying attention, but ADHD is caused by impulsiveness, while OCD behaviors are fueled by anxiety and aim to prevent danger.

OCD is often found alongside anxiety, depression, or tic disorders, which adds to the confusion for doctors. In kids, sudden onset of OCD symptoms after a strep infection (PANDAS) may be wrongly seen as behavior problems.

Why Is Misdiagnosis So Frequent?

OCD often gets incorrectly diagnosed, and many studies highlight this issue. One review published in the Journal Of Obsessive-Compulsive And Related Disorders indicated that about 50.5% of OCD cases are wrongly identified. Another study in the Journal of Clinical Psychiatry shows that misdiagnosis happens more often when obsessions cover sensitive subjects like sex or violence. Lack of awareness among doctors and patients feeling uncomfortable sharing their symptoms also contribute. This leads to delays in treatment, inappropriate medications, and ongoing distress.

How Can Misdiagnosis Be Prevented?

Here are some useful tips for patients and healthcare providers to reach a more accurate diagnosis:
Be clear about your behaviors. Share details about your obsessive thoughts and the actions you take—how often they happen, how long they last, and the anxiety they cause.

Understand the differences between ADHD and OCD. Talk to your doctor about whether your behaviors come from anxiety-related rituals (OCD) or from impulsivity and poor attention (ADHD).

See a specialist. Clinical psychologists or psychiatrists who know about the different types of OCD and the DSM-5 categories can provide an accurate assessment.

Utilize structured tools. Methods like the Yale-Brown OCD Scale (Y-BOCS) help measure severity and monitor treatment progress.

Get a second opinion. If you think your concerns are not being understood, it's perfectly reasonable to seek another evaluation, especially before starting or stopping any treatment.

OCD might be masked by repetitive actions or bothersome thoughts, but its impact can be significant, especially when diagnosed incorrectly. By comprehending what OCD really is, recognizing shared conditions like ADHD, and openly discussing symptoms, individuals can help healthcare providers make correct diagnoses and provide prompt, effective assistance.
