<s>[INST] I am having a problem with my memory . I am 73 yrs old and find in the morning my mind is foggy, I sometimes get confused and forgetful. I used to have a very good memory. I just bought a vitamin by Natrol called brain spped memory. Contains 50 MG thiamin, 125 mg niacin , 10MG B6,1,000 MG folic acid , 500 MG B12,125 pantothenic acid . My doctor does not believe in natural medications. What do you think? [/INST] Sir. There is no harm in taking the medications you have mentioned as all are vitamins. If you have disturbed sleep or obstructive sleep apnea because of which you have a disturbed sleep which may cause early morning confusions and somnolence. As you are 73 years old there can be changes in the brain at this age. So I would suggest you to consult a neurologist and may undergo few blood tests and an MRI brain to rule out dementia and other age related brain changes. You need to undergo a detailed neuropsychiatric evaluation and a sleep study. </s>
