Hello,
Thank you very much for posting this question in HCM
Let me tell you that any symptom in medicine can be due to various causes and the primary objective of the rerating doctor is to establish the cause and deal accordingly. Apart from that the presence or absence of certain symptoms, age of the patient, gender, weight and other co-morbid medical conditions (For example
diabetes, blood pressure, kidney problem, past history of
stroke in heart/ brain, psychiatric disorder etc) can help us narrow down the possibility.
Let us see your problem. I have noted your problem. One definite possibility of stroke is there. If the stroke is early, it may not be seen by
CT scan. Better to get MRI scan brain to rule out stroke. Stroke is a medical emergency. If MRI scan is normal, the other possibility could be
myasthenia gravis.
Basically your father needs clinical evaluation by a
neurologist who can determine the neurological deficits and plan the tests accordingly. Note that the management of these two conditions are different
So you need urgent medical attention by a neurologist
Hope these will help you
