Common mood disorders include Major Depressive Disorder, Bipolar disorders, Persistent Depressive Disorder, and Seasonal Affective Disorder. Mood disorders are caused by a deficiency of serotonin in the brain. Someone struggling with this type of mood disorders have trouble feeling right about themselves, the direction of their life, and their ability to handle stressful life situations. Ironically, Alcohol, Opiates, Marijuana, and Benzodiazepines all cause the brain to make more serotonin. When someone with a mood disorder uses one of these drugs, they start to feel normal and their brain quickly makes the link that the individual needs this to function and be normal. Again, his behavior, unbeknownst to the individual, encourages self-medicating and later a destructive addiction that could rob them of their goals and aspirations.
Common anxiety disorders like Post Traumatic Stress Disorder, Obsessive-Compulsive disorder, and Generalized Anxiety Disorder can be diagnosed with a co-occurring disorder therapist. Anxiety Disorders are all caused by a deficiency of Dopamine in the brain. Someone with an anxiety disorder feels an impending sense of urgency or fear that something bad is going to happen causing a restless and uneasily feeling through-out their day to day. Alcohol, Opiates, Marijuana, Benzodiazepines, Cocaine, and Methamphetamines all cause the brain to make more dopamine. When someone with an anxiety disorder self-medicates with one of these drugs, they start to feel a sense of relaxation, relief and contentment with their current direction in life.
Psychotic disorders include Schizophrenia and Schizoaffective disorder are less common but still present in co-occurring disorders and substance abuse disorders. These types of disorders are caused by excessive amounts of dopamine in the brain. Since most drugs produce dopamine, an excessive amount can produce psychotic symptoms such as hallucinations, delusions and paranoia. The more dopamine the drug produces, the more likely it is to produce those symptoms pf psychosis. Flooding the brain with chemicals like dopamine and serotonin can have long lasting negative effects on the way the body functions.
