Many people in Denison who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who suffer with mental health issues in Denison, Iowa also become involved in substance abuse at some time in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to ease the symptoms of an underlying psychological condition. Some addicted individuals aren't even diagnosed with a psychological condition, and only when they make it to a drug treatment facility 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 disorders so that they have a strong chance of remaining clean and sober and psychologically stable in the future.
