Stem cell therapy for sequelae of cerebral infarction is aimed at the lasting effects that remain after the acute event, such as weakness, sensory change, or difficulty with speech. This is a different question from acute stroke treatment, and the research addressing it is at an earlier stage than emergency care protocols.
Ask which specific effect the proposed treatment is intended to address, since sequelae vary widely between individuals. Ask also how long after the original event treatment is usually given, as studies differ on this point substantially. The interval since your stroke may affect whether a clinic considers you a candidate.
Assessment deserves particular attention here, because change in function can be gradual and difficult to judge subjectively. Ask what measures would be used, who performs them, and at what intervals. Continue rehabilitation alongside any treatment, and keep your neurologist informed so that progress is evaluated against your existing care record. Ask what would be documented before treatment begins, since without a recorded baseline any later comparison rests on recollection rather than measurement.
