Psychiatric disorders result from a complex interaction between biological (e.g., genetics), psychological (i.e., patterns of
thinking; life experiences), and social (e.g., relationships, work) factors resulting in altered brain function. Fortunately,
however, since the brain is highly plastic, as a growing body of scientific evidence has demonstrated, psychiatric disorders
are readily treatable. The goal of psychiatric treatment is to modify brain function, or rewire the brain, using a
combination of specific psychological and biological methods.
Effective treatment begins with a comprehensive diagnostic evaluation, investigating current symptoms and reviewing
past treatment history, medical history and recent test results, and family history. In addition, a careful exploration of
thoughts, behaviors and life factors contributing to maintenance of the symptoms will be undertaken.
Each patient will receive personalized treatment based on the information collected during the diagnostic assessment.
The treatment plan may include ordering additional diagnostic tests (blood tests, brain scans); evidence-based
psychotherapy (e.g., ERP for OCD; other specialized CBT approaches for depression, panic, ADHD); and/or medication
Treatment is most effective when there is a collaborative relationship between patient and doctor/therapist.
