SYMPTOMS OF EAR DISEASE
virus infections of the middle and internal ear. In cases in which the bony
wall of the horizontal (lateral) semicircular canal is eroded by disease,
giddiness is experienced on stooping or on suddenly turning the head.
Neuritis of the vestibular nerve may be due to toxaemia. Tumours of the
eighth nerve, cerebellar lesions such as abscess or tumour and Meniere's
disease give rise to vertigo. Arteriosclerotic changes in the blood vessels of
the brain are a common cause of giddiness in old people. Vertigo may be
severe and of short duration, or it may be more or less constantly present in
which event it is usually less severe.
