Psychosis is one of the most common conditions in later life with a lifetime risk of 23 %. Despite its high prevalence, late-onset psychosis remains a diagnostic and treatment dilemma. There are no reliable pathognomonic signs to distinguish primary or secondary psychosis. Primary psychosis is a diagnosis of exclusion and the clinician must rule out secondary causes. Approximately 60 % of older patients with newly incident psychosis have a secondary psychosis. In this article, we review current, evidence-based diagnostic and treatment approaches for this heterogeneous condition, emphasizing a thorough evaluation for the "six d's" of late-life psychosis (delirium, disease, drugs dementia, depression, delusions). Treatment is geared towards the specific cause of psychosis and tailored based on comorbid conditions. Frequently, environmental and psychosocial interventions are first-line treatments with the judicious use of pharmacotherapy as needed. There is an enormous gap between the prevalence of psychotic disorders in older adults and the availability of evidence-based treatment. The dramatic growth in the elderly population over the first half of this century creates a compelling need to address this gap.

Introduction: Detecting cognitive impairment in diverse, health disparities communities is an urgent health care priority. Methods: The Brooklyn Cognitive Impairments in Health Disparities Pilot Study investigated quantitative aspects and liking of a computerized cognitive performance assessment, Cognigram, among individuals 40 years in traditional and nontraditional primary care settings. Results: Cognigram was piloted in the Emergency Department, Family Medicine, and Geriatric Psychiatry clinics: 58 adults (23 men, 35 women), 67.9 6 9.8 years (range 43-91), completed the Cognigram and 5-item liking survey. The observed liking range was 2 to maximum score 5 (67% scored 4-5; no sex or age differences).Discussion: The Cognigram was well liked in waiting rooms of primary care settings. Assistance from a trained adult and clinic endorsement were keys to success. How the Cognigram performs in a geographically compact, population-dense global setting, such as Brooklyn with high vascular disease risk and a plethora of health disparities, is being tested.
