[|Human|] I am from Bangladesh. My father s problem is when he walk he feel vertigo. He feels uneasy to keep walking due to vertigo. His BP is normal,no diabetics, He feel uneasy to stand on foot for long time. He is 64 years old. We consult with Bangladeshi doctors. They told he is well, there may be slight problem in Vestibulocochlear Nerve. One of the doctor identified it is as a peripheral vertigo. Now I am worried about it. Why he is not recovering???Please help Sir.
[|AI|]  Hello, There is a condition called BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV) which could be correctly referred to as a "peripheral" vertigo.  It is common in all people above age 55.  It is as a result of some degeneration in the INNER ear apparatus where balance is executed and signals sent to the brain via the VESTIBULOCOCHLEAR nerve.  There is a set of exercises you could look up on the internet on YouTube called the Brandt-Daroff Exercises.  They will show you exactly how you can help your father (or how a specialist such as a neurologist or neurobiologist or even ENT specialist) without much effort though you have to follow the instructions carefully and perform these exercises for at least 7-10 days before your father may experience full relief.  Also, in 50% of cases the condition may return after successful treatment in which case you need to repeat the whole set of exercises for another 7-10 days and so forth. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
