A stroke is defined as a neurological deficit of sudden onset which is caused by cerebrovascular disease and persists for longer than 24 hours. The consequences of stroke can include disability and early death. Approximately 80% of first strokes are ischaemic (i.e. due to the thromboembolic or thrombotic occlusion of an intracranial artery). Primary haemorrhage (haemorrhagic stroke) and subarachnoid haemorrhage constitute 10% and 5% of strokes, respectively.
In general, acupuncture is believed to stimulate the nervous system and would cause the release of neurochemical messenger molecules. The resulting biochemical changes affect the body’s homeostatic mechanisms, thus encouraging physical and emotional well-being. There have been many physiological studies on acupuncture and stroke, mostly from China. They indicate multiple possible mechanisms by which acupuncture treatment may benefit in the management of stroke:
After the treatment of acute stroke, patients are advised of lifestyle changes that can help to avoid a further vascular events. These consist of smoking cessation, weight loss for those who are overweight, decreasing dietary salt intake, regular exercise, and avoiding excessive alcohol. They are also considered for drug therapy like antiplatelets, a statin and antihypertensives to further prevent vascular events.
中風可定義為由腦血管疾病引起的突發性神經功能缺損，持續時間超過 24 小時。中風的後果可以包括殘疾和過早死亡。大概 80% 的首次中風都是屬於缺血性的（即由於顱內動脈的血栓栓塞或血栓性閉塞）。原發性出血（即出血性中風）和蛛網膜下腔出血分別佔中風的10%和5%。
