Wernicke-Korsakoff syndrome (WKS) is a serious brain condition due to a thiamine deficiency (i.e., vitamin B1) that is primarily caused by chronic alcohol consumption and malnutrition. WKS consists of two stages. First, the acute phase (i.e., Wernicke's encephalopathy) is characterized by confusion, indifference, and delirium. Second, the chronic phase (i.e., Korsakoff's syndrome) is marked by memory problems (e.g., amnesia and confabulation), executive function deficits (e.g., decision-making), and disinhibition. These symptoms increase the risk of problematic behaviors and involvement in the criminal justice system. Because these symptoms also make it difficult to navigate legal processes (e.g., waiving legal rights, participating in one's defense, and complying with the court conditions), greater awareness of WKS among criminal justice and mental health professionals is imperative. Developed for professionals in criminal justice, legal, and forensic settings, this innovative training introduces the symptoms, causes, warning signs, co-occurring conditions, and consequences of Wernicke-Korsakoff syndrome. Attendees will learn evidence-based practices and approaches for interviewing, screening and assessment, and intervention and management of individuals with WKS. Cutting-edge research in forensic neuroscience and neurocriminology will be highlighted throughout the training to reinforce key learning objectives.
