<P> 焦虑症是一种以焦虑情绪为主的神经症,以广泛和持续性焦虑或反复发作的惊恐不安为主要特征,常伴有自主神经紊乱、肌肉紧张与运动性不安,临床分为广泛性焦虑障碍与惊恐障碍两种主要形式 。广泛性焦虑症大多起病于20-40岁,而惊恐发作多发生于青春后期或成年早期 。<BR> 广泛性焦虑障碍又称慢性焦虑症,是焦虑症最常见的表现形式 。
缓慢起病,以经常或持续存在的焦虑为主要临床相 。
1.精神焦虑<BR> 精神上的过度担心是焦虑症状的核心 。表现为对未来可能发生的、难以预料的某种危险或不幸事件的经常担心 。有的患者不能明确意识到部分他担心的对象或内容,而只是一种提心吊胆、惶恐不安的强烈的内心体验,称为自由浮动性焦虑 。有的患者担心的也许是现实生活中可能发生的事情,但其担心、焦虑和烦恼的程度与现实很不相称,称为预期焦虑 。
