There is still hope for healing after a stroke. Even the aged and the sick who have had a stroke can recover. Early rehabilitation, comprising physical, occupational, and speech treatments, yields the best results. After rehab is completed, further treatment may be needed to improve function or prevent future problems. For example, patients may need medications to reduce the risk of another stroke or dementia. Stroke is one of the leading causes of death in the world. It is also one of the most disabling conditions. Although research has made progress in understanding the disease and improving treatment options, no cure exists. However, with proper treatment, most people who suffer a stroke can regain some degree of movement or ability to speak again. People who have never had a stroke cannot understand how devastating it can be. The brain is a very complex organ and losing part of it can cause paralysis on one side of the body or even of both sides. In addition, many people who have had a stroke feel depressed because they are no longer able to do the things they loved doing before their attack. Their family and friends can help them get back to work or take care of themselves by giving them support during this difficult time. Stroke is a common term for any injury to the brain caused by blocked arteries breaking down causing a clot to form.
