This consists of an accumulation of blood in the cerebral vessels. The countenance is flushed, the eyes suffused, light becomes intolerable, and there is singing in the ears, vertigo, momentary loss of speech, and sometimes delirium. Simple congestion is merely a functional affection, and in a slight or moderate degree involves no immediate danger. It may, however, produce apoplexy and sudden death. It is caused by any mechanical impediment to the return of blood from the head, as tumor of the neck, heart disease, etc. It is a concomitant to nearly every inflammatory cerebral affection.
