头昏——不清晰感持续的头脑昏昏沉沉的不清晰感为主,多伴有头重、头闷、头胀、健忘、乏力.·不伴随神经系统定位体征;·不受视觉和听觉的影响;·由于神经症或慢性躯体疾病所致头晕(dizziness)——头重脚轻头晕无自身或外界物体旋转感,常表现以间歇性或持续性的头重脚轻和摇晃不稳感、行走不稳为主症,多于行立起坐中或用眼时加重.
·前庭阵发症是周围性眩晕常见的病因之一,国外文献报道,约占眩晕门诊的4％.认识的历史·一些反复发作性眩晕,由于发作时间很短(往往数秒),一天发作多次,发作间歇期无症状,临床评估困难,所以诊断无从下手.最早于1975年由Jannetta医生发现并命名为失能性位置性眩晕(disabling positional vertigo),主要表现为短暂性的眩晕发作,可能源于神经血管之间的压迫,致病机制极其类似
