Epidemiological studies have reported associations between alcohol consumption or abuse and occurrence of delusional disorder (F.22) rather than in general population. Alcohol has not been described as the main cause of the delusional idea, but is an enhancer factor which would inhibit behavioral brake and executive function in prefrontal cortex facilitating the development of the existing delusional idea.

We want to confirm this association in our influence area so this study aims to report compared frequency of alcoholism in DD versus a control group published in andalusian population.

To review the literature on the potential links between alcohol abuse and delusional disorder and this relationship in general population.

This poster presents a brief but updated systematic literature review on the associations between DD and alcohol abuse. We will also present data from a relatively large case-mix of 2049 patients with the diagnosis of delusional disorder resulting from a thorough retrospective, medical-record based, assessment of patients attended in our clinical catchment area.

In our sample, alcohol abuse and other drugs consumption was significantly less common in Delusional Disorder than in other psychoses.

This result suggests that alcohol and other drugs consumption can be a greater importance parameter in other psychoses correlates than in delusional disorder.
