[|Human|] I ve been experiencing sensations as if my brain is shaking inside. When this happens, I ve noticed that my vision is clearly moving in a rapid up and down motion. I had an MRI and CT and EEG, an there were no adnormalities. I have also been diagnosed with Vertigo resulting from the inner ear.
[|AI|]  Hello, You may have a condition known as OSCILLOPSIA which refers to fields of vision that are in motion with head movements.  The underlying pathological mechanism involves a loss of image stabilization by loss of reflex control of eye muscle control when a person has their gaze fixated.  Things such as toxicity, infection (most importantly meningitis) or side effects from antibiotics can cause the condition.  Desalinating disease such as MS can also cause this condition, as well as abnormal movements of the eyes referred to as nystagmus. I recommend you seek an opinion from a NEURO-OPHTHALMOLOGIST.  Vertigo from inner ear problems will not produce this phenomenon. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
