Chapter 15, Problem 2CCS
Summary Introduction
Case summary:
Brian Rhen was suffered from repeated episodes of vertigo. The diagnosis was done with benign paroxysmal positional vertigo that can be caused by head trauma. He experienced vertigo whenever rolled over a bed or turning his head side by side. The diagnosis of BPVV was confirmed by using a test called Dix-Hallpike maneuver.
Characters in the case:
Brian Rhen and a neurologist.
Adequate information:
Nystagmus was observed during the test for diagnosis of BPVV that involves the involuntary jerking eye movements whenever the head is subjected to the specific rotational changes.
To determine:
The explanation for Mr. Rhen’s condition.
