Co -occurring Mental Disorders among In-patients in a Substance use Disorder Treatment Center in Plateau State, Nigeria

Patients with psychoactive substance use disorders (SUD) often have co- occurring medical and mental disorders. This occurs as a result of a number of factors, for instance, drug abuse may facilitate the full expression of a latent psychiatric disorder; mental disorder may lead to SUD (drugs used for self- medication; or both SUD and mental disorders are caused by the same underlying brain deficit such as genetic vulnerability, neurotransmitter abnormality, structural or functional abnormality, and so on. After obtaining ethical clearance, the case notes of all patients who were admitted in the Centre for Addiction Treatment and Research, (CATR) Vom, Plateau state throughout the first quarter of year 2019 were traced. A systematic random sample of every third consecutive patient was selected beginning with the first patient admitted and relevant data were collected and analyzed. A total of fourty- eight (48) in-patients were analyzed. Ninety -four percent (94%) of the patients were males, the mean age of 23.6 + 5 years with 46% being below 25 years of age. Fourty-six percent (46%) had cannabis as their primary drug followed by alcohol (32%) and opioids (28%). Only 1 % had a history of injecting drug use. Twenty-nine percent (29%) of the SUD patients had co-occurring depression, nine percent (8%) had anxiety disorder, and five percent (4%) had Post Traumatic Stress Disorder (PTSD) in addition to their substance use disorder. In line with sustainable development goals (SDG) goal 3.5 which seeks to “strengthen prevention and treatment of substance abuse including narcotics drug abuse and harmful use of alcohol”; identifying co-occurring mental disorders among patients with substance use disorders is one way of moving closer towards achieving this SDG.
