[|Human|] My grandfather suddenly fainted three days back..it seemed his hearbeat had stopped and his eyes rolled up.My aunt tried to revive him..and he was fine after that.We all thought it must be heart related but doctors ruled it out. MRI was done..and black spot on the left side of his brain.He also has constant pain in his left arm .Doctors have said he suffers from seizures.How serious it is?..my grandfather is 83 year old
[|AI|]  Hi Smith, Thanks for writing in. As per your description, it seems that your grandfather could have suffered from a stroke or an acute disorder in the blood level of certain substances. It can also be due to Alzheimer and several other conditions. This would be leading to the seizures. The outlook can be decided only once we identify the cause. At this stage, your grandfather needs a complete workup. Hope this helpsRegards
