Can damaged neurons regenerate after a stroke?

 While damaged neurons in the brain generally do not fully regenerate after a stroke,the brain can partially repair itself through a process called neuroplasticity,where existing neurons can sprout new connections to take over functions of the damaged area,allowing for some recovery of function;however,most experts agree that completely replacing  dead neurons with new ones is not possible in the adult brain.

                      Axonal sprouting:Healthy neurons near the damaged area can extend new projections to connect with other neurons,contributing to functional recovery.

                         More recent research also suggests that the brain may actually create nerve cells through a process called neurogenesis.There is a lot that still has to be discovered and researched in this domain.
