Neuropsychology Clinical Training Sites:   1) MGH Psychology Assessment Center (PAC), established in 1997, at Massachusetts General Hospital, combines assessment specialists from the Departments of Neurology, Psychiatry and Pediatrics. By coming together in one center, it is now possible for allied professionals to address these different aspects of psychological functioning, and discuss their findings concerning the patient. In doing so, we provide a better assessment, both to the patient and to the referring physician, school or family. The faculty of the Psychology Assessment Center is also dedicated to research that furthers our understanding of disorders that we assess and the training of practitioners to provide care for patients seeking such services. The PAC is staffed by 13 psychologists representing child, developmental, clinical and neuropsychology. Interns and post-doctoral fellows are trained in personality, educational, emotional and neuropsychological assessment depending on their training track or post-doctoral program.   2) Acute Psychiatry Service (APS). The APS is the largest and busiest 24 hour emergency psychiatric service in the metropolitan Boston area. Interns provide 4 hours of coverage every week in the APS evaluating and assessing emergency walk-in patients. On-site supervision and training are provided by attending psychiatrists. Interns collaborate and work closely with psychiatry residents in assessing and establishing appropriate treatment dispositions for patients in acute distress.   3) Inpatient Psychiatric Unit (Blake 11). Blake 11 is a 24 bed locked unit. The patient population of Blake 11 is quite varied, although certain classes of patients tend to predominate: patients with complex medical/psychiatric illnesses, geriatric patients posing difficult differential diagnostic questions, such as depression vs. dementia, patients with chronic treatment resistant mental illnesses who require periodic acute psychiatric care, patients suffering from eating disorders and patients with Axis II conditions resulting in instability and the need for close supervision.
