Genetic factors might be involved in stroke prognosis, however the role of brain-derived neurotrophic factor (BDNF) in stroke recovery is unknown. We have studied BDNF -196 G>A and -270 C>T polymorphisms in ischemic and hemorrhagic stroke and their impact on stroke prognosis. There was higher occurrence of BDNF -270 CC genotype in patients with hemorrhagic than ischemic stroke (96% versus 86%, p=0.0495). In hemorrhagic stroke BDNF -196 GG carriers scored better in NIHSS at admission (14.23 versus 21.00, p=0.0192) and after 7days (8.60 versus 15.00, p=0.0408) of onsets. None of the determined polymorphisms had any impact on 30-day early outcome in ischemic and hemorrhagic stroke.
