My father-in-law,M/68years/Non-Diabetic,suffering from left parietal ischemic infarcts,since 20th May,2013. He is at Nagpur,Maharashtra,and till to-date talks in monosyllables slurred speech.Before his walk was limped,but now improved by 30%.He can see-identify people,but when asked for the persons name,he seems to look hither-thither as if searching for information in his mind.Will he regain full speech, as he has lifestyle history of Cigarette Smoking since last 20 years.Please suggest Ayurveda medication to be taken to restore speech.
