The prevalence of psychiatric disorders in the population with Intellectual Disability varies considerably between different studies; however, all studies consistently report a much higher prevalence than in the normal population. Furthermore, individuals that receive a precise diagnosis of a mental disorder represent only a small part of all disabled people that come in contact with a psychiatrist. Like anyone else, a person with Intellectual Disability can present with emotional, behavioral, interpersonal or adaptive problems that do not constitute a real psychiatric disorder, yet they can still benefit from seeing specialist.
