Vertigo
a dizziness or giddiness in which the individual or the objects around the patient appear to be whirling about. The term is from the French, meaning a whirling. Scientists are pleased to say that when the patient seems to be himself whirling he has subjective vertigo, and objective vertigo when the surrounding objects seem to whirl. A very real imitation may be brought on by whirling rapidly until dizzy. Genuine vertigo may result from disorders of the heart or stomach or from a defect of the eye. Bright's disease is accompanied not infrequently by vertigo. Certain drugs, as hemp, opium, belladonna, nicotin, and digitalis, may bring on vertigo. The treatment for this affliction consists chiefly in ascertaining and removing the cause.
