BACKGROUND: After ischemic stroke, many factors influence the restitution of functions.
In particular they include the patient age, the initial stroke severity and the presence of cognitive and neuropsychological deficits.
In this study we investigated whether a polymorphism in the gene encoding for brain derived neurotrophic factor (BDNF) influences improvements of motor functions and everyday activities. METHODS: Patients with subacute ischemic stroke (n = 67) were examined at the beginning of an inpatient neurological rehabilitation, after 4 weeks of treatment and after 6 months. The Barthel index (BI) and the Rivermead motor assessment (RMA) were used to measure motor functions and everyday activities. Patients were allocated to three groups (valine [Val]/valine, val/methionine [Met] and Met/Met) depending on the BDNF polymorphism at codon 66. RESULTS: The 3 groups (Val/Val, n = 34 patients, Val/Met, n = 26 and Met/Met, n = 7) showed significant improvements in BI and RMA after 4 weeks and after 6 months as compared to the preceding measurements. The BI and RMA were positively correlated. The three groups did not differ with respect to the extent of improvement. CONCLUSION: After ischemic stroke, motor functions and everyday activities improved continuously over a period of at least 6 months. The BDNF polymorphism did not influence this development. |
