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

Petersén Å, Wörtwein G, Gruber SH, El-Khoury A and Mathé AA.Neuroscience Letters 451(2): 148-151 (2009)AbstractA prevailing hypothesis is that neurogenesis is reduced in depression and that the common mechanism for antidepressant treatments is to increase it in adult hippocampus. Reduced neurogenesis has been shown in healthy rats exposed to stress, but it has not yet been demonstrated in depresse

Petersén Å, Wörtwein G, Gruber S and Mathé A.Neuroscience letters 436(3): 305-308 (2008)AbstractHippocampal neurogenesis is potentially implicated in etiology of depression and as the final common mechanism underlying antidepressant treatments. However, decreased neurogenesis has not been demonstrated in depressed patients and, in animals, reduced cytogenesis was shown in healthy rats exposed to s
