Strictly speaking, each of the causes of vertigo can occur at all ages, but different diseases have a certain age spectrum, so for young people, the causes of vertigo have some characteristics of their own. Clinically, inflammation, trauma, poisoning, autoimmune diseases, congenital anomalies, etc. are more frequent. (1) For vestibular systemic vertigo, the following diseases may be more common: (1) Otogenic: external auditory canal stare, acute otitis media, eustachian tube obstruction, tympanic membrane entrapment, otosclerosis, labyrinthitis, inner ear complications of chronic otitis media (fistula formation), Meniere’s disease, motion sickness, benign episodic positional vertigo, inner ear concussion, etc. (2) Eighth to brain nerve damage: pontocerebellar horn tumor (e.g., auditory nerve sheath tumor), auditory neuritis, auditory nerve injury (rock cone fracture), drug (e.g., streptomycin, gentamicin) poisoning. (3) Brainstem damage: brainstem encephalitis, medullary cavitation, multiple sclerosis, vestibular neuronitis, fourth ventricle tumor, subclavian artery steal syndrome. (4) Cerebellar lesions: cerebellar earthworm tumor, cerebellar injury, cerebellar abscess. (5) Brain lesions: temporal lobe tumor, temporal lobe epilepsy. (6) Cervical spine lesions: cervical hypertrophic changes and cervical disc herniation. (7) Epilepsy: some vertigo is actually seizures, which can be unexplained or caused by some of the above diseases. (8) Congenital: such as skull base depression. (2) For non-vestibular systemic vertigo, the following diseases may be more common: (1) Eye diseases: extraocular muscle paralysis, refractive error, poor prescription, congenital visual impairment, etc. (2) Cardiovascular diseases: hypertension, hypotension, arrhythmia, heart failure. (3) Systemic diseases: intoxication (alcohol intoxication), metabolic disorders (hypoglycemia, hypothyroidism), infections, etc. (4) Hematologic disorders: such as anemia, etc. (5) Autonomic instability: such as erectile dysregulation, chronic fatigue syndrome. (6) Intracranial pressure changes: such as primary or secondary hypocranial pressure. (7) Drug side effects: such as side effects of carbamazepine, triazolam, etc. (8) Functional disorders: such as neurosis, hysteria, hyperventilation syndrome.
