It is quite common for men and women who are afflicted with a mental health issue to also be plagued by a co-occurring alcohol and drug abuse disorder. In truth, it is more widespread than one would think and many people currently in drug and alcohol rehabilitation programs in Sunnyvale may have mental health disorders which are often undiagnosed. Treatment professionals at successful drug and alcohol rehab programs in Sunnyvale know how to identify persons with co-occurring mental and alcohol and drug abuse issues so that both issues can be handled simultaneously while the person is in rehab. Simply because both need to be addressed, the individual must remain in rehab until they are psychologically stable, not just abstinent.
