Petersén Å, Hult S and Kirik D.Neurodegenerative Diseases 6: 154-164 (2009)AbstractHuntington's disease (HD) is a neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene. Although it is characterized by progressive motor impairments, cognitive changes and psychiatric disturbances are major components of the disease. In addition, recent studies have shown that other non-m
