# Impact of addictive comorbidity on bipolar disorder type I

## TL;DR

This study examines how addiction affects people with bipolar disorder type I, finding that addiction is common and linked to worse outcomes like poor treatment compliance.

## Contribution

The study provides new insights into the prevalence and impact of addictive comorbidity in BD I patients in a specific clinical setting.

## Key findings

- Substance use disorder was reported in 31% of BD I patients.
- Addictive behavior was significantly linked to poor treatment compliance and irregular follow-up.
- No association was found between substance use and suicidal behavior or disease progression.

## Abstract

Among all mental pathologies, bipolar disorder (BD) is the one in which addictive comorbidity is most frequent.

Recent studies suggest that this comorbidity has harmful consequences, threatening patients’ quality of life.

Describe addictive comorbidity and determine its prevalence in a population of patients with BD I.

Study the impact of addictive comorbidity on the evolution of BD I.

A cross-sectional, comparative study was conducted over a six-month period in the after-care unit of psychiatric wards at Razi Hospital, including patients treated for BD I according to DSM 5 criteria and stable on treatment.

The study included two phases: first, sociodemographic, clinical and therapeutic characteristics were collected using a pre-established form. The CAGE, DUDIT and MARS scales, validated in Arabic, were then administered.

We included 100 patients (60 men and 40 women) with a mean age of 43.55 years.

Substance use disorder (SUD) was reported in 31% of our population; 22 alcohol users with a mean CAGE score of 1.23 (0-3), while psychoactive substance use was reported in 19 patients with a mean DUDIT score of 13.37 (0-28).

Forensic history was higher in the group of patients with comorbid SUD (p<0.001). Poor compliance with treatment and irregular follow-up were also significantly more associated with addictive behavior, respectively p=0.008 and p=0.048.

We found no association between SUD and suicidal behavior or evolutionary symptoms of the disorder.

SUD are generally factors in the poor prognosis of BD. It is important to identify the determinants of this comorbidity, so that these risk factors can be appropriately targeted through appropriate therapeutic interventions and thus limit these negative consequences.
