Pure O is sometimes mistakenly seen as a “less severe” form of OCD.

For those who experience symptoms of this disorder, the characteristic intrusive thoughts can be very disruptive and distressing.

Many experts think the term “pure O” is a misnomer.

Symptoms of Pure O

Obsessive-compulsive disorder itself involves having reoccurring obsessions and behaviors (compulsions).

According to the DSM-5-TR, OCD is characterized by obsessionsand/orcompulsions.

Compulsions are clearly excessive or not connected in a realistic way to the problem they are intended to address.

This can be problematic because many patients may not even recognize it as a compulsion.

What Causes Pure O?

Later, research further divided aggressive obsessions into fears over impulsive harm and unintentional harm.

Psychotherapy

Research suggests that cognitive-behavioral therapy can be very effective at treating pure O.

The goal of such therapy is to teach patients how to manage their symptoms without acting upon compulsions.

This increases distress in the short term but can improve symptoms and behaviors over time.

Second-generation antipsychotics, also known as atypical antipsychotic medications, are also used to augment SSRIs.

The specific treatment (or combination of treatments) depends on a patient’s particular needs.

They can help you understand your symptoms and find the best treatment to meet your needs.
