老年人手抖是疾病先兆
<FONT size=4>冬天，有的老人会出现手反复发抖，多数人往往以为是天冷、年龄大、身体衰老的表现。专家介绍，事实并非如此。<BR><BR> 据马凯博士介绍，通常手抖分为生理性手抖和病理性手抖。正常人在某些情况下会出现生理性手抖，但<SPAN id=S__699_ADDIV_10 onmouseover="S__699.SHOWFLOW(不属于,10,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(不属于,10,event);" onmouseout="S__699.hidden(10);;this.style.textDecoration=underline;" oncontentextmenu="return false">不属于</SPAN>疾病，也不需要治疗。这种手抖的幅度小而速度快，多在安静时出现，是一种细小的、快速的、无规律的抖动，常与精神紧张、恐惧、情绪激动等有关。<BR><BR> 病理性手抖常是某些疾病的征兆，医学上称为震颤，是指手不随意地颤动，常反复出现，<SPAN id=S__699_ADDIV_4 onmouseover="S__699.SHOWFLOW(主要,4,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(主要,4,event);" onmouseout="S__699.hidden(4);;this.style.textDecoration=underline;" oncontentextmenu="return false">主要</SPAN>分为静止性手抖和<SPAN id=S__699_ADDIV_5 onmouseover="S__699.SHOWFLOW(运动,5,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(运动,5,event);" onmouseout="S__699.hidden(5);;this.style.textDecoration=underline;" oncontentextmenu="return false">运动</SPAN>性手抖两种类型。其中静止性手抖是在肌肉放松的情况下出现的手抖，这种手抖在运动时减轻或消失，睡觉时多数人可消失，典型的疾病如帕金森病；运动性手抖是指在运动时出现的手抖，手接近目标时抖动加重，安静时不太明显，常见于<SPAN id=S__699_ADDIV_8 onmouseover="S__699.SHOWFLOW(脑部,8,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(脑部,8,event);" onmouseout="S__699.hidden(8);;this.style.textDecoration=underline;" oncontentextmenu="return false">脑部</SPAN>病变，典型的疾病如原发性震颤。上述疾病如不能得到早期<SPAN id=S__699_ADDIV_7 onmouseover="S__699.SHOWFLOW(诊断,7,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(诊断,7,event);" onmouseout="S__699.hidden(7);;this.style.textDecoration=underline;" oncontentextmenu="return false">诊断</SPAN>、及时治疗，会完全失去自理能力。<BR><BR> 当然，单凭手抖是不能确定诊断的，出现手抖的疾病常见的也有十余种，这就需要专业医生结合其他表现综合判断，才能进行针对性地治疗。以帕金森病为例，它往往从一侧手指安静时抖动开始，缓慢发病，<SPAN id=S__699_ADDIV_0 onmouseover="S__699.SHOWFLOW(逐步,0,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(逐步,0,event);" onmouseout="S__699.hidden(0);;this.style.textDecoration=underline;" oncontentextmenu="return false">逐步</SPAN>侵犯一侧上肢、下肢，继而另一侧出现类似表现，还伴有肌肉僵硬，酸痛乏力，写字越写越小，精细动作难以完成，动作迟缓，走路呈小碎步向前冲，面部缺乏表情。部分病人还可有多汗、便秘、皮肤油腻等表现。<BR><BR> 目前，出现手抖的绝大多数疾病通过药物及手术治疗，都能获得<SPAN id=S__699_ADDIV_1 onmouseover="S__699.SHOWFLOW(良好,1,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(良好,1,event);" onmouseout="S__699.hidden(1);;this.style.textDecoration=underline;" oncontentextmenu="return false">良好</SPAN>效果。因此，如果您身边的老年朋友出现类似情况时，一定要到正规医院及时就诊。专家：北京市<SPAN id=S__699_ADDIV_6 onmouseover="S__699.SHOWFLOW(宣武,6,event);this.style.textDecoration=none;" style="CURSOR: pointer; COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick="S__699.SHOWFLOW(宣武,6,event);" onmouseout="S__699.hidden(6);;this.style.textDecoration=underline;" oncontentextmenu="return false">宣武</SPAN>医院功能神经外科研究所副主任医师马凯博士<!--advertisement code begin--><!--advertisement code end--></FONT> 学习了.谢谢. 学习了 老年人手抖是疾病，应格外注意。
