I also had a brain stem stroke 15 years ago, and suffer from vertigo. unfortunatey, this feeling hasnt gone away up to now, but I can say that it definately improves with time.
Hello Dear,
Episodic vertigo frequently occurs in patients suffering from ischemia in the distribution of the vertebrobasilar circulation. Vertigo is caused by disruption of the vestibular systems of the peripheral ear or the brainstem,cerebellum. The brain stem is the area of the brain that controls all of our involuntary, "life-support" functions, such as breathing rate, blood pressure and heartbeat. The brain stem also controls abilities such as eye movements, hearing, speech and swallowing. You should consult a neurologist about the vertigo as it is not good to get repeated vertigo attacks.
