This article will help you understand their similarities and differences and how healthcare professional, like psychiatrists, can help.
Are OCD and ADHD related?
OCD and ADHD are distinct conditions that operate in different ways. ADHD is considered an externalizing disorder, meaning it affects the ways a person interacts with their environment. While OCD is an internalizing disorder, meaning that it affects the way a person relates to themself.
OCD is characterized by intrusive and obsessive thoughts and sometimes leads to repetitive behaviors (compulsions). People living with ADHD might experience difficulties with inattention, hyperactivity, and impulsivity.
While some people have both OCD and ADHD, and some research suggests they may have overlapping genetic and neurobiological factors, they are distinct conditions and there is no cause-and-effect relationship between these two disorders.
Because there is an overlap in symptoms between OCD and ADHD, it can be challenging for patients to accurately assess their own condition—that’s why speaking with a mental health professional about how you’re feeling is so important.
