My father has been a chain smoker for many years. Recently, I have noticed that he has become very lethargic, has lost interest in daily activities, and is also showing signs of forgetfulness. Although he has reduced his smoking, he has not quit completely. I am concerned whether these symptoms could be a result of long-term smoking. Kindly advise.

Yes, chronic smoking can contribute to cognitive decline, oxygen deprivation, or even early dementia. Evaluation by a neurologist is advised.

I recovered from COVID 19 on 20th April and was treated with Fabiflu and Deflazacort tapering dose for 9 days along with blood thinners for 15 days. My blood report on 18th May showed SGPT at 153 and SGOT at 59. A follow up report on 18th June shows SGPT at 90 and SGOT at 55. I currently do not have any symptoms except mild burning and tingling sensations in my feet and legs. How long it usually takes for these liver enzyme levels to return to normal?
