1. Stroke - by Wikipedia Indonesia
Stroke (bahasa Inggris: stroke, cerebrovascular accident, CVA) adalah suatu kondisi yang terjadi ketika pasokan darah ke suatu bagian otak tiba-tiba terganggu. Dalam jaringan otak, kurangnya aliran darah menyebabkan serangkaian reaksi biokimia, yang dapat merusakkan atau mematikan sel-sel saraf di otak. Kematian jaringan otak dapat menyebabkan hilangnya fungsi yang dikendalikan oleh jaringan itu. Stroke adalah penyebab kematian yang ketiga di Amerika Serikat dan banyak negara industri di Eropa (Jauch, 2005). Bila dapat diselamatkan, kadang-kadang penderita mengalami kelumpuhan di anggota badannya, hilangnya sebagian ingatan atau kemampuan bicaranya. Beberapa tahun belakangan ini makin populer istilah serangan otak. Istilah ini berpadanan dengan istilah yang sudah dikenal luas, "serangan jantung". [...]
2. Stroke - by Wikipedia (B. Inggris)
A stroke, sometimes referred to as a cerebrovascular accident (CVA), is the rapid loss of brain function due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism), or a hemorrhage. As a result, the affected area of the brain cannot function, which might result in an inability to move one or more limbs on one side of the body, inability to understand or formulate speech, or an inability to see one side of the visual field.
A stroke is a medical emergency and can cause permanent neurological damage and death. Risk factors for stroke include old age, high blood pressure, previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, tobacco smoking and atrial fibrillation. High blood pressure is the most important modifiable risk factor of stroke. It is the second leading cause of death worldwide.
An ischemic stroke is occasionally treated in a hospital with thrombolysis (also known as a "clot buster"), and some hemorrhagic strokes benefit from neurosurgery. Treatment to recover any lost function is termed stroke rehabilitation, ideally in a stroke unit and involving health professions such as speech and language therapy, physical therapy and occupational therapy. Prevention of recurrence may involve the administration of antiplatelet drugs such as aspirin and dipyridamole, control and reduction of high blood pressure, and the use of statins. Selected patients may benefit from carotid endarterectomy and the use of anticoagulants. [...]
A stroke is a condition in which the brain cells suddenly die because of a lack of oxygen.
A stroke can be caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain.
The patient may suddenly lose the ability to speak, there may be memory problems, or one side of the body can become paralyzed.
This Medical News Today information article provides details on the two types of stroke, who are at risk, what its causes are, its symptoms, how a stroke is treated, and how strokes can be prevented. [...]
