小脑卒中

定义

A cerebellar 中风 happens when 血液供应 to the cerebellum is stopped. This part of the brain helps with body movement, eye movement, 和 balance.

There are two main types of 中风: 缺血性 和 出血性. An 缺血性 中风 is the most common type.

Medical care is needed right away. Cells in the brain die if they are without oxygen for more than a few minutes. 这可能是致命的.

原因

An 缺血性 中风 happens when blood flow is blocked. 这可能是由于:

• A clot from another part of the body that breaks off 和 gets trapped in a blood vessel supplying the brain
• A clot that forms in an artery that supplies blood to the brain
• A tear in an artery supplying blood to the brain

A 出血性 中风 is caused by a burst blood vessel. Blood pools in the brain. This slows or stops the flow of blood 和 causes a buildup of pressure on the brain.

风险因素

This problem is more common in older adults 和 people with a family history of 中风.

Problems that affect blood vessel health 和 blood flow can raise the risk of 中风. 一些例子是:

• 的历史 transient 缺血性 attacks (TIA)
• Lack of physical activity
• 吸烟
• 酒精 使用障碍
• 肥胖 or 代谢 并发症状
• 2型糖尿病 或前驱糖尿病
• 高血压
• 高胆固醇
• Heart issues such as previous heart attack, atrial fibrillation or enlarged heart
• Diseases of blood vessels such as 颈动脉狭窄 or 动脉粥样硬化
• 物质使用 of 可卡因, amphetamines, or heroin

Daily habits can also play a role. 一些例子是:

• 吸烟
• A diet that is high in saturated fat, trans fat, cholesterol, 和 sodium
• 缺乏身体活动
• Cocaine, amphetamines, or heroin use

症状

症状突然出现. A person with a cerebellar 中风 may 有:

• Problems moving or walking
• A feeling of spinning when they are still or having balance problems
• Muscle weakness or tremors
• 头疼
• Problems chewing, swallowing, 和 speaking
• Problems sensing pain 和 temperature
• 恶心和呕吐
• Hearing 和 vision problems
• 失去知觉

诊断

A 中风 needs to be diagnosed fast. The doctor will ask about symptoms 和 health history. A physical exam will be done. The doctor will look for signs of nerve or brain problems.

Blood tests may be done to look for clotting problems.

Images may be taken of the brain. 这可以用:

• CT扫描
• 血管造影—to look at the heart 和 its 血液供应
• CT血管造影
• 核磁共振成像扫描
• Magnetic resonance angiography (MRA)
• 多普勒超声

Heart function will be checked. 这可以用:

• 心电图 (ECG)看一下 heart's electrical activity
• 超声心动图 去看心脏 肌肉运动

治疗

Emergency care will be needed. The heart 和 lungs may need help A tube may also be placed to help with breathing. 其他选择包括:

药物

For an 缺血性 中风, medicine may be given to:

• Dissolve clots 和 stop new ones from forming
• 薄血

For a 出血性 中风, medicine may be given to:

• Work against any blood-thinning drugs a person has been taking
• Reduce how the brain reacts to bleeding

手术

Options to treat an 缺血性 中风 are:

• Embolectomy—a tube is passed through blood to remove a clot or deliver medicine to break it up
• Vertebrobasilar 血管成形术 和 支架—a major artery to the brain is widened 和 a mesh tube is left there to help keep it open

康复

Therapy may be needed to regain lost skills. 选项有:

• Physical therapy—to help with movement
• Occupational therapy—to help with daily tasks 和 self care
• Speech therapy—to help with swallowing 和 speech
• Psychological therapy—to provide support after the 中风

预防

The risk of 中风 can be lowered by:

• Managing long term health problems, such as high blood pressure 和 diabetes
• Keeping a healthy weight through diet 和 exercise
• Eating a diet that is low in fat 和 cholesterol 和 rich in whole grains, fruits, 和 vegetables
• 不 吸烟、呼吸 others' smoke, or vaping
• 限制酒精
