NCT03164798

Brief Summary

This study aims to develop the quantitative biomarker to establish the individualized strategy in stroke rehabilitation. Brain-derived neurotrophic factor (BDNF) acts on certain neurons of the central nervous system (CNS) helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses. BDNF in CNS can be assessed by analysing serum BDNF. The final objective of this study is to demonstrate a role of biomarker of BDNF in stroke rehabilitation to establish the individualized strategy.
