[Sleep disorders and addictions: Impact on quality of life and relapse vulnerability].

There is a bidirectional association between sleep disorders and addiction. Sleep problems negatively impact the quality of life of subjects with addictions (psychological state, pain perception, drug use). Sleep disorders are associated with a higher risk of relapse among sujects with addiction. The association between sleep disorders and relapse may be related to poor quality of life or to a higher level of craving. Maintaining abstinence and reducing craving episodes among subjects with addiction is the first-line treatment to reduce sleep disorders. Specific interventions focused on sleep disorders are needed when sleep disorders persist during abstinence and may improve global addiction outcome.
