Moya Moya Patients: Stroke Recovery And Rehabilitation

Moyamoya disease is a rare, chronic and progressive condition of the arteries in the brain. It is caused by blocked arteries at the base of the brain, which leads to narrowing and blockages that can eventually cause ischemic strokes, hemorrhagic strokes, and seizures. While there is no medication that can stop or reverse the progression of the disease, treatment involves managing symptoms, improving blood flow to the brain and controlling seizures. The most effective treatment for Moyamoya is revascularization surgery, which has a good long-term outlook, especially for children. However, postoperative stroke is a common complication in patients with Moyamoya, and the risk factors for this are still being determined.

Surgery can help moya moya patients recover after a stroke

Moyamoya disease is a rare, chronic and progressive condition of the arteries in the brain. The name "moyamoya" means "puff of smoke" in Japanese and refers to the appearance of the tangle of small blood vessels that form to compensate for the blockage. This blockage can lead to strokes, which are a common symptom of moyamoya.

While there is no medication that can stop or reverse the progression of moyamoya disease, surgery can help moya moya patients recover after a stroke. Surgery is the preferred treatment for moyamoya disease. The goal of surgery is to bypass the blockage and allow new blood vessels to develop, bringing blood and oxygen to the brain. This is known as revascularization surgery and is the most effective treatment for moyamoya.

There are several surgical procedures that can be used to treat moyamoya disease, including Encephaloduroarteriosynangiosis (EDAS), Encephalomyosynangiosis (EMS), and Superficial temporal artery-middle cerebral artery (STA-MCA). These procedures involve either freeing up a scalp artery or a muscle from the temple region of the forehead and placing it in contact with the brain surface, or directly suturing a scalp artery to a brain surface artery. Over time, new blood vessels will form, improving blood supply to the brain.

Full recovery from surgery may take six to twelve months, but many patients see an improvement in their symptoms almost immediately. It is important to note that deficits from previous strokes are unlikely to improve with surgery.

Recovery time varies from patient to patient

The recovery time for moya moya patients after a stroke varies from person to person. While some patients may see an improvement in their symptoms almost immediately, full recovery from surgery can take anywhere from six to twelve months. It is not uncommon for patients to experience persistent symptoms for several weeks after surgery. Most patients experience a gradual recovery over the course of several weeks.

It is recommended that patients take off approximately four to six weeks from work for surgical recovery. During this time, patients should be patient with themselves and give their bodies adequate time to heal. Over-exertion can result in a feeling of low energy.

While surgery is the preferred treatment for moya moya, medication may be used as an alternative when surgery is not an option. Medications such as aspirin may reduce the risk of a damaging stroke, but they cannot prevent the narrowing of arteries.

Moya moya patients should avoid certain medications

Moyamoya patients should avoid certain medications, as some drugs can increase the risk of bleeding or impair blood flow through the bypass graft. Here are some medications that moya moya patients should typically avoid:

• Oral birth control pills or hormone replacement therapy: These medications have a higher risk of causing blood clots, which could potentially block the bypass graft and trigger a stroke.
• Anticoagulants: While anticoagulants like lovenox or coumadin can be used in rare instances to treat unstable patients with frequent symptoms, they are generally avoided as long-term measures due to the risk of cerebral bleeding.
• Calcium channel blockers: While these drugs can help reduce headaches and transient ischemic attack symptoms, they can also lower blood pressure, which may increase the risk of stroke.
• Excessive caffeine: Caffeinated drinks can cause increased urination, leading to fluid loss. However, caffeine is not entirely prohibited and can be consumed in moderate amounts.

It is important for moya moya patients to consult their doctors or specialists before taking any medication to ensure their safety and effectiveness.

There are minimal lifestyle limitations after bypass surgery

Moyamoya disease is a rare, chronic and progressive condition of the arteries in the brain. It is caused by blocked arteries at the base of the brain, which leads to narrowing and blockages, and can eventually cause ischemic stroke, hemorrhagic stroke, and seizures. The name "moyamoya" means "puff of smoke" in Japanese, describing the appearance of the tiny vessels that form to compensate for the blockage.

While there are no medications that can stop or reverse the progression of moyamoya disease, there are surgical treatments available. Surgery is the most effective treatment for moyamoya and involves rebuilding the blood supply to the underside of the brain. The goal of surgery is to bypass the blockage and allow new blood vessels to develop, bringing blood and oxygen to the brain.

Following surgery, there are minimal lifestyle limitations for patients. They should avoid wearing anything tight around the area in front of the ears that might constrict the grafts. There are no other specific limitations. Most patients experience a gradual recovery over several weeks, and it is recommended that they take off approximately 4-6 weeks for surgical recovery.

Full recovery from surgery may take six to twelve months, though many patients see an improvement in their symptoms almost immediately. If major bleeding into the brain has occurred, the damage may be permanent, and prompt treatment is important to preserve brain function.

Medication can help reduce the risk of a damaging stroke

Moyamoya disease is a rare, chronic and progressive condition of the arteries in the brain. It is caused by blocked arteries at the base of the brain, resulting in a reduced blood supply to the brain. The name "moyamoya" means "puff of smoke" in Japanese, describing the appearance of the tiny vessels that form to compensate for the blockage.

While there is no medication that can stop or reverse the progression of moyamoya disease, medication can help reduce the risk of a damaging stroke. For those experiencing strokes and TIAs (transient ischemic attacks or "mini-strokes"), medications such as aspirin may reduce the risk of a damaging stroke. Blood thinners can also help avoid clots and blockages, but they can also increase the risk of bleeding. The doctor will carefully assess each patient's unique situation when recommending any medicines. It is important to note that research has shown that aspirin alone is ineffective in treating moyamoya.

In addition to medication, revascularization surgery is an important treatment option for moyamoya disease. The goal of surgery is to bypass the blockage and allow new blood vessels to develop, bringing blood and oxygen to the brain. Surgery is generally recommended for moyamoya patients with recurrent or progressive TIAs or strokes.

The prognosis for patients with moyamoya is challenging to predict, as the disease's natural history is not well understood. However, early surgical treatment before a disabling stroke occurs can significantly improve the prognosis.
