This 3-hour course addresses one of the most rapidly growing populations on the planet—the elderly. The World Health Organization reports that for the first time in human history, the elderly outnumber the young (children under five). This course reviews the physical changes associated with the aging process and how they influence medication effects and side effects. It uses case studies to distinguish between “the 3-D’s”: delirium, depression and dementia. The course reviews pharmacological and empirically supported nonpharmacological interventions for these conditions. The information is then integrated to assist the mental health professional in making informed decisions and recommendations regarding the unique health care needs of the elderly.
