<s>[INST] Hi, I have been experiencing sever memory loss for example when I am in the shower I forget if I have washed my hair... I forget which streets to turn down that I drive on ever day.. I forget what I eat for lunch and I forget names and faces and while conversations quite regularly. I am only 21 years old so not sure what could be wrong, I also get very often headaches. [/INST] Hi, For any age, memory loss is not normal. So, for a 21 year old also, it is abnormal. You need further evaluation to determine the cause of memory impairment. This would include neuropsychological assessment, brain scan, vitamin B12 and thyroid blood tests. Hope I have answered your query. Let me know if I can assist you further. Take care. Regards, Dr. Sudhir Kumar, Neurologist </s>
