甲基苯丙胺和顱內出血之间的区别

甲基苯丙胺 vs. 顱內出血

基苯丙胺或甲基安非他命（英語：Methamphetamine，全名是)）是強效的中樞神經系統刺激劑，主要被用於娛樂用途，較少被用於治療注意力不足過動症和肥胖症，即便有也被當成第二線療法。甲基苯丙胺是在1893年發現，有二種对映异构：分別是左旋甲基苯丙胺（levo-methamphetamine）及右旋甲基苯丙胺（dextro-methamphetamine）。「甲基苯丙胺」一般是指左旋甲基苯丙胺及右旋甲基苯丙胺各佔一半的外消旋混合物。甲基安非他命較少被醫師處方，因為可能會，以及有用作春藥和欣快感促進劑等風險。而且已有療效相同，而對人體危害風險更低的替代藥物。 在美國能直接在市面上購買主成分為左旋甲基苯丙胺的吸入型因為它被視為非处方药。 甲基苯丙胺常因為它們的藥效動力學屬性而被非法交易，用於娛樂用途。非法使用甲基苯丙胺在亚洲部分地区、大洋洲和美国最为普遍。在美国，消旋以及左旋、右旋甲基苯丙胺均为。 Levomethamphetamine is available as an over-the-counter (OTC) drug for use as an inhaled in the United States. Internationally, the production, distribution, sale, and possession of methamphetamine is restricted or banned in many countries, due to its placement in schedule II of the United Nations Convention on Psychotropic Substances treaty. While dextromethamphetamine is a more potent drug, racemic methamphetamine is sometimes illicitly produced due to the relative ease of and limited availability of chemical precursors. In low doses, methamphetamine can elevate mood, increase alertness, concentration and energy in fatigued individuals, reduce appetite, and promote weight loss. At higher doses, it can induce, breakdown of skeletal muscle, and bleeding in the brain. Chronic high-dose use can precipitate unpredictable and rapid s, (e.g., paranoia, hallucinations, delirium, and delusions) and violent behavior. Recreationally, methamphetamine's ability to has been reported to lift mood and increase sexual desire to such an extent that users are able to engage in sexual activity continuously for several days. Methamphetamine is known to possess a high addiction liability (i.e., a high likelihood that long-term or high dose use will lead to compulsive drug use) and high dependence liability (i.e. a high likelihood that withdrawal symptoms will occur when methamphetamine use ceases). Heavy recreational use of methamphetamine may lead to a, which can persist for months beyond the typical withdrawal period. Unlike amphetamine, methamphetamine is to human midbrain neurons. It has also been shown to damage serotonin neurons in the CNS. This damage includes adverse changes in brain structure and function, such as reductions in grey matter volume in several brain regions and adverse changes in markers of metabolic integrity. Methamphetamine belongs to the and. It is related to the other s as a positional isomer of these compounds, which share the common chemical formula:. 顱內出血（ICH）是頭部颅骨內出血。這種情況可能導致血液或血塊壓迫到腦神經造成腦神經壞死。顱內出血包含：s 和s)、蛛网膜下腔出血、、和硬膜下血肿。 顱內出血致死率非常高，是一個，必須立即送醫，分秒必爭。.

高血壓

血压（Hypertension (HTN)或high blood pressure），全稱动脉高血压（Arterial hypertension），是一种动脉血压升高的慢性病。血压的升高使心脏推动血液在血管内循环时的负担增大。血压有两种，收缩压和舒张压，分别为心脏跳动时肌肉收缩（systole）或舒张（diastole）时的测量值。正常静息血压范围为收缩压90–139mmHg（最高读数）和舒张压60–89mmHg（最低读数）。血压持续等于或高于140/90毫米汞柱mmHg时则为高血压。 高血压分为或。约90–95%的病例为"原发性高血压"，即没有明显病因的高血压。 其余5–10%的病例由影响肾脏、血管、心脏或内分泌系统的其它病症引发（继发性高血压）。 高血压是中风、心肌梗塞（心梗）、心衰竭、动脉瘤（如主动脉瘤）及外周动脉疾病等重症的主要之一，也是慢性肾病的起因之一。即使轻度的动脉血压升高也能缩短期待寿命。改变饮食及生活方式可以改善对血压的控制并减少相关的健康风险。但如果生活方式改变没有起效或效用不佳则这些患者常需要使用药物治疗。 高血壓類性疾病名列中華民國十大死因之一。.
