Dual diagnosis is given to those who are suffering from both substance abuse and mental illness. Individuals begin with one disorder; then the other develops, often as a result of the first disorder. In order for treatment to be effective, it must take into account both aspects of the comorbid disorders in the dual diagnosis.
Mental Illness and Drug or Alcohol Use
Patients suffering from mental illness often turn to drugs or alcohol in the hopes that using these substances will make them feel better. For a short time, these drugs have the desired effect. Drugs or alcohol can improve mood, increase energy, and increase a sense of well-being. Sometimes this process is referred to as "self-medicating," as the individuals attempt to feel better by the use of substances instead of seeking treatment for their mental illness symptoms. That is, until the body develops a tolerance for the drug. Then more of the drug is needed to obtain the desired effect. Long-term use and increased tolerance can lead to addiction, either physical, psychological, or both.
Drug or Alcohol Use and Mental Illness
Drug and alcohol use cause changes in the brain over a period of time. This is due to a flood of dopamine brought on by many substances that can damage brain cells and nerve receptors. Over time, production of several types of neurotransmitters can decrease resulting in many problems, including those affecting mood and personality. These changes to the brain can result in many symptoms associated with mental illness. These symptoms include:
- Depression
- Mania
- Anxiety
- Aggressive or violent behavior
- Delusional thoughts
- Hallucinations
- Paranoia
How Prevalent is Dual Diagnosis
People receive a dual diagnosis quite frequently. According to statistics provided by Mental Health America, dual diagnosis occurs at the following prevalence rates:
- Alcohol abusers: 37 percent also have a mental illness
- Drug Abusers: 53 percent have a mental illness
- Those diagnosed with mental illness: 29 percent abuse drugs or alcohol
Increased Risk of Drug Use Depending on Mental Illness
Most people with mental illness actually have an increased risk of developing drug or alcohol abuse, more so than those without mental illness. This is due to chemical imbalances in the brain that need to be handled with medical treatment. Some mental illnesses carry a greater risk of developing substance abuse than others. For example, those who suffer from schizophrenia, bipolar disorder, and antisocial personality disorder are over ten times more likely to suffer from dual diagnosis than the general population. Those with anxiety, panic disorder, and severe depression are approximately four times more likely than the general population to suffer dual diagnosis.
Which Came First?
Doctors cannot always pinpoint whether the mental illness or the substance abuse problem came first, though through a lot of questions and answers there is usually some clue when making that diagnosis. However, it is important that individuals are off of the drugs or alcohol before a doctor can make an accurate diagnosis and begin proper treatment for both problems.
Treating Those with Dual Diagnosis
After detoxification from substances, those with dual diagnosis should receive treatment for both, their mental illness and substance abuse issues. Medication may be necessary to treat the symptoms of the mental illness, depending on the diagnosis. Individual and group counseling can be effective for both getting
addiction help and dealing with mental illness.
