Hello there.  I can understand your concern.  For the further line of treatment, you need to give a better history. What do you mean by stroke? For you is it related to brain or something else like a heat stroke? What first line of treatment have you given? What medications is he on currently? Whats his blood pressure and sugar levels like now? Do yourself a favor and consult a MD consultant physician in person for further evaluation and management. Best regards. Dr. Anil kumar jain.
