Mental disorders, such as depression, anxiety disorders, addiction and schizophrenia are the core challenge of most health care systems around the world. In the EU alone, each year 27% of the total adult population - this corresponds to 83 Million citizens - suffer from mental disorders. Depression alone affects almost 20 million ranking in the EU as the most disabling disorder of all diseases. Binge eating and temper tantrums could become conditions if physicians adhere to the new manual of mental health disorders. Only about half of American children and teenagers who have certain mental disorders receive professional services, according to a nationally representative survey funded in part by the National Institute of Mental Health (NIMH). The survey also provides a comprehensive look at the prevalence of common mental disorders.
