In the decade between 1996 and 2006 the use of anxiety medication, anti depressants, and antipsychotic drugs has increased by 73% in adults and by 50% in children. In those over 65, the use of the drugs has doubled in the same time period. In 2006 16% of the elderly were on some sort of psychotropic medication. In the same time period, the number of children diagnosed and treated for mental health conditions doubled. This data was obtained by researchers from the National Center for Health Statistics, the Agency for Healthcare Research and Quality, the Substance Abuse and Mental Health Services Administration and the Social Security Administration.
