The Neuropsychiatry Special Interest Group (NSIG) was established at the WPA Congress in Vienna in September 2023. It is a forum for the interchange of the latest developments in the diagnosis and management of neuropsychiatric disorders. It endeavours to embed neuroscientific principles in the practice of psychiatry in general by disseminating educational material and organising seminars, symposia and webinars. It will foster greater collaboration between Psychiatry and Neurology, Neuropsychology and other medical disciplines to foster a holistic view of mental illness.
