Comorbilidad psicopatológica en consumidores de cocaína en tratamiento ambulatorio

Abstract

Cocaine addiction is a growing health problem and among its complications highlights the high prevalence of mental disorders co-occurring with abuse and dependence. This psychopathological comorbidity varies according to the time of consumption and the age of the patient. Early detection of psychopathological disorders associated with drug consumption is necessary to optimize health care and to improve the prognosis. The main aim of the present study was to estimate the prevalence and characteristics of psychopathological comorbidity in a population of subjects seeking outpatient treatment for cocaine use. We recruited 110 subjects using cocaine by nasal insufflations evaluated with the PRISM (Psychiatric Research Interview for Substance and Mental Disorders), a semi-structured diagnostic interview that differentiates primary mental disorders from those induced by the drug. This population presented 86.4% male and had a mean age of 36.5. They displayed a pathological use of cocaine of 7 years and the presence of psychopathology was associated with a higher number of DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders- IV-TR) criteria for substance dependence. The lifetime prevalence of some psychopathological comorbidity was 61.8%, highlighting mood disorders (34.5%), followed by anxiety disorders (22.7%) and psychotic disorders (15.5%). About 20% showed antisocial personality disorder and 21% borderline personality disorder. From among mood and psychotic disorders, the induced disorders were more frequent, while the primary disorders were more prevalent in anxiety.
