Transient Ischemic Attack (TIA)

What is a transient ischemic attack?

A transient ischemic attack (TIA), often called a “mini-stroke,” occurs when blood circulation to the brain is briefly interrupted, typically because of a blocked artery or ruptured blood vessel. The signs are the same as a stroke, but they are usually only present for a few minutes. A TIA is considered a warning sign that a full stroke could occur in the future.

We work in multidisciplinary teams of specialists and therapists that share insights, leading to better treatment decision-making and outcomes, as well as lower costs and time savings. Throughout the treatment process, we will work closely with the doctor who referred you to ensure a smooth transition back to your regular care. While you are with us, you will receive expert care, excellent communication, and genuine compassion.

短暂缺血性攻击的原因

The majority of TIAs and strokes are considered preventable and most of the risk factors can be managed. People who are overweight, inactive, or heavy drinkers or smokers are at a higher risk for having a stroke. People with diabetes, high blood pressure, high cholesterol, obstructive sleep apnea, or heart disease are at higher risk.

Signs of a transient ischemic attack

The most noticeable symptoms of a TIA include a sudden, severe headache,视力问题,difficulty speaking, and sudden paralysis or numbness of the face, arms,or legs on one side. Coordination problems are also common. Someone who has suffered a transient ischemic attack might have confusion, memory loss, and difficulty reading or writing. Unlike a full-blown stroke, these symptoms usually disappear within about five minutes.

Diagnosis

Once a person has suffered a TIA, their risk of a stroke increases as much as 80% so it’s important to see your doctor immediately. Your doctor can order a brain imaging test, including a CT scan or MRI, to identify whether damage was done. A Computer Tomography(CT)scan uses radiation to create a picture of the brain. It can help determine the cause, location, and extent of brain injury.Magnetic Resonance Imaging (MRI)可以用于更详细的图像。可能使用的其他诊断工具包括颈动脉超声，脑血管造影，超声心动图或血流测试。

治疗

Several medications are available to help prevent a patient from suffering a future stroke. Anticoagulants and anti-platelet drugs, such as aspirin, may be recommended to reduce the risk.

Doctors may decide to perform a procedure to reduce the risk of future strokes, such as removing plaque blocking a carotid artery. An angioplasty might also be used to insert a stent to support an opened artery.

Risk factors for future stokes should be mitigated through lifestyle and diet changes.
