[|Human|] My sister used to fell down while walking when she was 17 years old. She also started to forget things. she used to blame others like why you said this to me. After 7 or 8 months she was having seizuers. After that she went in coma and she came out of coma after almost 6 months with the help of brain specilist. Before that she did not had any brain specilist traetment because everyone was suggesting diffrent treatments. When she came out of coma she forgot every thing and she was like a kid(3 years old). Her hands were closed and she wasnt standing straight. With time she remembred some things like her dogs name but she doesnot now about toilet or bathroom. Some times she goes by herself.  Now its been one and a half year she is having same symptoms and doctor said her br.ain is not draining a water back and she need an operation. Could you please tell me more about this we are so worried and do not have enough money
[|AI|]  Hello and welcome to Chat Doctor. Thanks for your query. I understand that you are concerned about your sisters problems. From the description of her symptoms, this appears to be a serious neurological problem, but with the limited information that you have provided, it is not possible to pinpoint a definite diagnosis. So, I would suggest that you take her to a neurologist for a detailed evaluation and an opinion on further management. You have mentioned that you have already seen a doctor and that she was advised surgery. If so, it is better to have surgery at the earliest in order to prevent further complications. Wish you all the best.
