For most of the major obsessive-compulsive and related disorders, there is an increased risk for the development of substance abuse. This may result in a diagnosis of a co-occurring substance use disorder.
Whenever someone is diagnosed with a substance use disorder and another mental health disorder, treatment becomes more complicated. Both disorders must be treated simultaneously in order for full recovery to be reached.
Types of Official Diagnoses
The Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition (DSM-5) is the go-to manual published by the American Psychiatric Association (APA) for diagnosing different forms of mental illness.
