The symptoms of vertigo with low head are considered to be related to otolithiasis and cervical spondylosis, which should be analyzed with the form of patient onset: 1. Transient vertigo with visual rotation when the patient lowers his head is considered to be caused by otolithiasis, i.e. benign paroxysmal positional vertigo. The patient can be cured by manual repositioning, and the attack will be characterized by rotational nystagmus. 2. Consider it to be caused by cervical spondylosis, which belongs to vertebral artery type cervical spondylosis. When the patient lowers his head and other movements, it may cause the patient’s vertebral artery to be compressed by the intervertebral disc, causing the patient to have insufficient blood supply to the brain, and the patient will experience dizziness, visual rotation, nausea, cold sweat and other symptoms, accompanied by stiffness, pain and discomfort in the neck. In particular, dizziness will be aggravated when the patient makes movements such as turning the head.
