Bessel van der Kolk is also a noted psychiatrist, author, researcher and educator based in Boston, USA. He states that there is a much higher incidence of psychiatrists administering prescribed medications among patients who have government insurance. Since most mental illnesses are trauma-induced, medication has little to no effect. Psychiatrists are supposed to rule out trauma before diagnosing but its more rare than not. Therefore, its often easier to be screened by a psychologist or therapist first. Van Der Kolk often suggests EMDR, meditation, neurofeedback, yoga, mindfulness, sensory integration, and the arts for treatment of trauma or PTSD. Symptoms of trauma are often manifested by anxiety, hypervigilance, depression and behavioral problems that medication really doesn't help on a long-term basis.
