It is quite common for individuals who are afflicted with a psychological issue to also struggle with a co-occurring alcohol and drug abuse disorder. Frankly, it is more widespread than one would imagine and many men and women currently in alcohol and drug rehabilitation facilities in Littleton may have mental health disorders which are often undiagnosed. Rehab specialists at successful alcohol and drug rehabilitation centers in Littleton know how to identify individuals with co-occurring mental and substance abuse disorders in hopes that both concerns can be simultaneously addressed while the individual is in rehabilitation. Because both need to be addressed, the individual should not leave rehabilitation until they are psychologically stable, not just abstinent.
