Patients who become dizzy when they lift their heads and have dizziness attacks related to changes in the position of the head should mainly consider the following two aspects: 1. If patients become dizzy when they lift their heads, accompanied by brief visual rotation and rotational nystagmus of the eyeballs for no more than one minute, they should consider benign paroxysmal positional vertigo, which is also caused by otoliths. It can be clarified by doing positional test and treated by manual repositioning. 2. If dizziness occurs when the patient raises his head and the degree of dizziness persists, it should be considered cervical vertigo caused by cervical spondylosis. When the head is tilted back excessively or turned to a certain orientation, it may cause the protruding cervical disc to compress the vertebral artery, which may easily cause the patient to have dizziness symptoms. Patients may also experience stiffness, pain, discomfort or numbness in the neck.
