Blood clot in front lobe of brain.

My grandfather became unconscious on 29 jan and fell on the floor,had 2 stitches above his left eyebrow on head. We consulted the doctor and blood test and CT scan was done.The doctor told there is an old blood clot in brain front lobe whose symptoms didn't appear earlier and that now it has affected my grandfather.After that the doctor prescribed medicine and told us to consult neurosurgeon.The neurosurgeon told that the cure is only through medicine.My grandfather was fine before he fell on the floor. After he fell he was a bit unsound from his mind . He wasn't able to sleep properly and was thinking too much unnecessarily After taking medicine for some days his mind is stable but he is not able to walk properly and his legs and hands are not  coordination properly. Today he was more weak. Please suggest which medicine to take and other measures.As you can see from the attached file, among the two sets of prescriptions we are currently taking palampur civil hospital medicine
