10 Best Spinal Deformity Correction doctors in Sector 120

my grandmother went into a coma caused by hepatic encephalopathy. she was completely fine until her hands started trembling and she started vomiting one morning. there were no symptoms before that. she does have liver cirrhosis. she was taken to a hospital approximately 12 hours after this happened and placed into an ICU with a ventilator. she regained consciousness in about 24 hours, after the ammonia had been flushed out from the brain and the chest. she was in critical condition, but has been recovering well. now off the ventilator she does have noticeable personality changes yet good memory. this to me is extremely scary. she also seems less aware of the environment and takes longer to answer. could these affects be temporary or permanent?
