脑出血为什么会极度兴奋~

那要看情况严重程度拉 `
脑子的问题可大可小的`有的时候随便碰下就没了``有的时候硬敲都不一定有事`
先看看医生怎么说吧`

一个人极度兴奋和高兴时的表现可以用 一个成语来形容“手舞足蹈”
手舞足蹈 [ shǒu wǔ zú dǎo ]
基本释义 详细释义
[ shǒu wǔ zú dǎo ]
双手舞动,两脚跳跃。形容高兴到了极点。《诗经·大序》:“永(咏)歌之不足,不知手之舞之,足之蹈之也。”
出 处
《孟子·离娄上》:“乐则生矣;全则恶可已也。恶可已;则不知足之蹈之;手之舞之。”

兴奋和紧张都是由交感神经传输的,在正常的情况下,不会引起人的不正常反映.但交感神经受到的刺激过大.就会出现了.不同的刺激会产生不同的症状.你说的情况不具体,不能确定,可能是你的血压高,或血管壁比较薄,极度兴奋和紧张会强烈的刺激神经,加速血液的循环.由血管压迫神经而引起的.建议一下查一下血压和血液的粘稠度,还有注意一下心态的平衡.长时间下去,容易的中风和脑血栓.有问题可以在问

温馨提示:回复只是给您提供参考意见,不能代替临床诊断。最后确诊还请到相关医院就诊:

那是得了胆碱能性荨麻疹 ,胆碱能性荨麻疹是荨麻疹的一种,建议去皮肤科去治疗! 自己治疗的话可以服些抗过敏的药,如西替利嗪1片/日+雷尼替丁1粒/2/日+Vc片2 片2/日.

胆碱能性荨麻疹,属于人们常说的风疹块的一种。当受热、精神紧张、摄入热的食物或饮料,或在运动后,体温略增,增热的血流刺激大脑体温调节中枢,兴奋胆碱能性神经并释放乙酰胆碱,正是因为机体对乙酰胆碱这种化学物质过敏,我们将过敏引起的症状称之为胆碱能性荨麻疹。

胆碱能性荨麻疹的症状特征

①不会出现皮疹,但明显感到有针刺、剧痒感。
②多发生于青年期,一般在遇热(热饮、热水浴)、情绪激动和运动后出现。当停止运动或平静以后,症状即可消退,严重的话,症状完全消退可能要经过数月或数年不等。
③常在躯干和肢体近端皮肤(腋、掌跖除外)出现红色的、2毫米左右的风团,这种风团速来速去不留痕迹。严重者可能伴有消化道症状,如腹痛、腹泻等。
多发生于青年期,在遇热刺激、情绪激动和运动后出现.

保持一个姿势久了,身体就会有发麻的感觉。当你改变姿势的时候,会感到非常的难受:刺痛、痉挛,然后是慢慢恢复知觉。这种发麻的滋味还真不好受。那么,为什么我们的身体会发麻呢?看了下面这篇文章你就会有所了解了。

The unnerving, separate sensations we feel when a body part "falls asleep" truly result from nerves under pressure.

Scientists, using the arm as an example of a limb that has fallen asleep, explain that the person, most likely, slept on the arm. This sleeping position exerted pressure on the nerves, which squeezed them and, thus, inhibited the messages the nerves carry to the brain and to the rest of the body. If sleeping on the arm also squeezed the blood vessels, oxygen normally carried to the nerves by these vessels never made it to its destination.

The nerves themselves comprise bundles of single celled fibers, with each fiber conveying a different sensation or message to the brain. The fibers vary in thickness and in the amounts of myelin, a protective sheath, surrounding them. These two variables determine the sensitivity of the nerve fiber to pressure and to oxygen deprivation. As a general rule, the thicker the fiber, and the larger the myelin sheath, the more sensitive it is.

When one removes the pressure on the nerves and on the blood vessels, in this case by a change in sleeping position, the nerve fibers awaken in order of their thickness and of the thickness of their myelin sheaths. Hence, the thickest and most protected ones awaken last. This gradual awakening process causes the different sensations we experience as the affected body part returns to its functional state.

The first sensation we experience is a tingling sensation, followed by a burning sensation, as the fibers that control pain and temperature now function and are again able to transmit these messages to the brain. Not until later, does the numbness we feel disappear, simply because the fibers that control touch and position are thicker fibers with thicker myelin sheaths. Similar fibers, known as motor neurons, travel in the same nerves, but take direct orders from the brain to the spinal cord to the muscles, and awaken shortly after those controlling touch and position. For this reason, after the numbness disappears, we regain our ability to move the affected body part, and life is finally backed to normal.

人体的大脑是人体最复杂的地方,我们通过听,看等方式接收外界的信息,当一部分信息传递到大脑时,有可能就会使我们的大脑产生共鸣,这样,大脑就会本能的发布一定的信息,就会刺激到我们的神经,就产生了那种麻的感觉了。而人在极度兴奋或极度紧张的状态下,神经处于紧绷的状态,对大脑的刺激也是最厉害,就会出现那种情况了

极度兴奋或极度紧张的状态,肾上腺皮质激素分泌增多,由于激素刺激引起,有时候还可以出现尿意感,是人体的一种应激反应,没有关系的.
