It is not uncommon for men and women who are afflicted with a psychological disorder to also have a co-occurring alcohol and drug abuse issue. In truth, it is more common than one would think and quite a few people currently in alcohol and drug rehabilitation centers in Catheys Valley, California may have mental health issues which are often undiagnosed. Rehab specialists at proven drug and alcohol treatment centers in Catheys Valley know how to identify persons with co-occurring psychological and substance abuse disorders so that these two issues can be handled simultaneously while the person is in rehab. Because both must be resolved, the individual must remain in treatment until they are mentally stable, not just abstinent.
