The common cause of dizziness with head tilt is cervical spondylosis. Cervical flexion and extension activities can stimulate the vertebral artery, resulting in spastic narrowing of the vertebral artery, causing cerebral blood supply insufficiency and symptoms such as dizziness, nausea, chest tightness and panic. Treatment methods include the following: first, external fixation of the cervical brace, so that the cervical spine is braked to avoid cervical rotation and flexion-extension activities. Even when resting in bed, the fixation should be clamped on both sides of the neck, which can avoid adverse stimulation of the vertebral artery and relieve the symptoms of dizziness. Second, cervical traction, by increasing the cervical spine gap, relieves cervical disc herniation and reduces vertebral artery spasm, thus relieving the symptoms of dizziness. Third, oral administration of vasodilator drugs such as flunarizine hydrochloride can restore blood supply to the vertebral artery and the brain by dilating the vertebral artery.
