Regenerative Medicine for Neurological Diseases with the Use of Electrical Stimulation

In current clinical practice, tissue plasminogen activator (t-PA) is the gold standard drug to be administred within three hours after the onset of cerebral infarction. In the near future, it will become acceptable to administer it within 4.5 hours of onset. Even if t-PA administration cannot be utilized for cerebral infaction patients because of time window limitations, the intravascular technique using the Merci(R) retreiver and the Penumbra(R) system can be applied to some patients with cerebral infarction. Not all cerebral infarction patients can be saved by these clinical therapeutic methods. Despite surviving the acute phase of cerebral infarction as a result of these clinical therapeutic methods, some patients suffer from permanent hemipa‐ resis in the chronic phase. It is for this reason that regenerative medicine must play more important role in solving this problem.
