Vertigo in seventy year olds may be caused by otolithiasis, vestibular neuritis, transient ischemic attack and so on. 1. Otolithiasis: Otoliths are dislodged due to trauma, structural deterioration, etc. Changes in the position of the otoliths may induce rotational vertigo and cause otolithiasis, resulting in the symptom of vertigo, which will be relieved on its own after a period of attack. 2. Vestibular neuritis: vestibular neuron damage may induce vestibular neuritis, nerve inflammation stimulation can cause sudden vertigo disease, causing vertigo in the elderly. 3. Transient ischemic attack: when patients suffer from atherosclerosis, altered blood flow dynamics and other conditions, it may lead to transient ischemia of the brain, inducing vertigo, which will affect the brain tissues if not treated in time. Vertigo in seventy-year-olds may also be caused by other reasons, such as Meniere’s disease, cerebral hemorrhage, etc., should go to the hospital in a timely manner to clarify the cause of the disease, and standardize the treatment under the advice of the doctor.
