2. Benign paroxysmal positional vertigo: when the head suddenly changes position, it is easy to cause otoliths to fall off, which may appear as dizziness and blurred vision, accompanied by nystagmus, blurred vision and other manifestations.
3. Insufficient cerebral blood supply: If there is insufficient cerebral blood supply, such as vertebral artery type cervical spondylosis patients, due to cervical degenerative changes, osteophytes and other reasons leading to vertebral artery compression, in the up, due to the position of a sudden change in the cerebral blood supply is easy to aggravate the insufficient cerebral blood supply, may lead to dizziness and blurred vision.
