According to the World Health Organization, stroke is the second leading cause of death in the world. It occurs due to rupture or blockage of blood vessels that disrupts blood flow to the brain. Scientists investigated why some patients experienced faster cognitive recovery.
Yulia Stankevich, senior researcher at ITC SB RAS, said that the brain is affected as a whole, and not in separate parts as previously thought. The changes affect cognitive, motor and psycho-emotional functions, as well as blood flow in the brain. Within three months, changes in the affected hemisphere stabilize and perifocal areas return to normal. Brain activity decreases at the stroke site, but nearby areas partially recover.
