At Haven House Treatment Center, a dual diagnosis treatment center in Los Angeles, we understand the critical importance of proper assessment for co-occurring issues and we offer a full range of inpatient services to treat even the most complex diagnosis. Research from the National Alliance on Mental Illness (NAMI) has confirmed the strong correlation between addiction and co-occurring mental health disorders. In fact, their recent studies have shown that approximately one third of all clients who abuse alcohol and 50% of clients who abuse drugs are simultaneously experiencing a mental health disorder. For anyone who has struggled with substance abuse or family members who love them, these statistics are highly significant as it is so often these untreated underlying issues that keep the addiction active. Addicts entering treatment so often report having spent years suffering from overwhelming feelings of anxiety or depression which made it virtually impossible to stop using drugs to self-medicate.
