Many individuals in Harleysville, Pennsylvania who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in Harleysville, Pennsylvania also become involved in substance abuse at some time in their lives. These dual diagnosis clients frequently turn to drugs or alcohol to self medicate in an attempt to relieve the symptoms of an underlying psychological disorder. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug rehabilitation center is this sort of psychological condition discovered. This alone can sometimes help resolve addiction issues and put the individual in a position to get rehabilitation for both conditions so that they have a strong chance of remaining abstinent and mentally healthy in the future.
