<unk>  is the branch of medicine dealing with mental disorders attributable to diseases of the nervous system.
It preceded the current disciplines of psychiatry and neurology, in as much as psychiatrists and neurologists had a common training (Yodofsky and Hales, 2002). However, neurology and psychiatry subsequently split apart and are typically practised separately. Nevertheless,<unk>  has become a growing subspecialty of psychiatry and it is also closely related to the field of Behavioral Neurology, which is a subspecialty of Neurology that addresses clinical problems of cognition and/or behavior caused by brain injury or brain disease. 'Behavioral Neurology /<unk> ' fellowships are jointly accredited through the United Council for Neurologic Subspecialties (UCNS), in a manner similar to how the specialties of psychiatry and neurology in the United States have a joint board for accredidation, the American Board of Psychiatry and Neurology (ABPN).
