In elderly people with insomnia and dizziness, the first consideration is that some patients with cardiac neurosis often feel dizzy when there is a dysfunction of the vegetative nerves, accompanied by insomnia. Patients with degenerative diseases of the nervous system, such as chronic cerebral hypoperfusion, cerebellar lesions or chronic occupational brain lesions, may also experience insomnia and dizziness. For otogenic diseases, such as chronic otitis media, vestibular neuritis, and Ménière’s disease, dizziness and insomnia can be caused. Cardiovascular diseases, such as chronic hypertension, atherosclerosis, chronic heart failure, sinus bradycardia, hyperviscosity, and hyperlipidemia, can also cause insomnia and dizziness in the elderly. Finally, patients with long-term anemia may also have the above clinical manifestations.
