title: Neuropsychiatric features associated with nutritional and metabolic status in a gastric bypass patient.
abstract: Bariatric patients may present for psychiatric evaluation due to exacerbation of preexisting psychiatric disorders, new onset psychiatric disorders and/or neuropsychiatric complications associated with abnormal nutritional and metabolic states following the surgical procedure. These neuropsychiatric complications can be insidious, and clinical manifestations may vary, possibly due to the individual central nervous system (CNS) vulnerability to nutritional decline. Lack of awareness of these complications and their symptoms can result in delays in diagnosis and treatment. Identifying and correcting underlying pathophysiologic processes that lead to such neuropsychiatric syndromes can be challenging. We report a case of a patient who developed a protracted course of mood and cognitive disorder after gastric bypass surgery, which illustrates some of the complexities encountered in diagnosing and managing these patients.
