Paroxismia vestibular (PV) é caracterizada por crises recorrentes de vertigem ou tontura, durando segundos a minutos, frequentemente várias vezes ao dia. Os ataques geralmente ocorrem espontaneamente, mas podem ocasionalmente ser induzidos por mudanças na posição da cabeça (que então precisa ser diferenciada da vertigem posicional paroxística benigna). Possíveis sintomas concomitantes são ataques curtos de tinnitus ou alterações na audição. No intervalo livre de crise podem ser observados comprometimentos leves a moderados da função vestibular ou audiológica. A compressão cruzada neurovascular do oitavo nervo é o mecanismo presumido. | |||
