At times, your legs stop working and you seem to forget important events like birthdays, etc. You are suffering from forgetfulness. You are suggested to stay mentally and physically active. Take quality sleep at night. Lack of proper sleep will trigger forgetfulness. Avoid sedentary life, socialize and get more organized. The treatment of forgetfulness depends on the treatment of the cause, if it is due to stress, stress is managed. Forgetfulness due to PTSD can be reversed but if it is due to dementia, blood pressure, blood glucose level, depression, anxiety, stress should be controlled at all cost. Smoking , alcohol, drugs or addiction if any should be stopped. You are suggested to get clinically examined by a GP, get all routine tests and investigations done for a complete medical check up.
