My father, 84 years old, has been experiencing on-again / off-again dizzy spells; he s on seizure medication for late-stage epilepsy (which has the side effect of causing dizziness) but it s odd to me that one day he can be fine and the next incapacitated?
Thank you for asking Chat Doctor.  My name is Chat Doctor.  As your father is known patient of seizures kindly get followup checkup every 03 months to revise medicine dosage.  As the age of father is 84,no need to worry if he experiences these type of symptoms. Just give him proper diet, timely medicine so that symptoms can be controlled. Also get check blood valproate level for the concentration of seizure medicine. His symptoms are controllable. Hope this may help you. Let me know if anything is not clear. Thanks.
