In childhood, we more frequently see OCD associated with ADHD in tic disorders, such as Tourette syndrome, a disorder that involves both vocal and motor tics for more than a year and is often associated with other psychiatric comorbidities in 60-80% of cases. The most specific and frequent comorbidity is ADHD, followed by OCD and ASD. Therefore, it is common to find children with tics, ADHD, and OCD in the context of a tic disorder like Tourette syndrome, especially around the age of 10-12 (the period of greatest tic exacerbation in chronic tic disorders or Tourette syndrome).

Regarding mood disorders, depression is the most common co-occurring condition with OCD (often as a consequence of the suffering caused by obsessions and the resulting impairment in daily functioning). Bipolar disorder can also occur, although less frequently than depression. In individuals with both OCD and bipolar disorder, proper management of medication is especially important, as the use of high doses of antidepressants (common in OCD) can increase the risk of manic decompensation in bipolar disorder (episodes of euphoria). It is essential to ensure adequate treatment with mood stabilizers (such as lithium or valproate) and to maximize the use of behavioral therapy to reduce the need for combining high doses of antidepressants.
