Transient ischemic attacks, or TIAs, are mini-strokes caused by decreased blood flow to the brain. They are often warning signs of an impending stroke. TIA symptoms can range from mild changes in speech and mental acuity to obvious loss of sensation or coordination. The heart cannot function properly because of decreased blood flow, and if it does, it can’t pump enough blood to the brain and body.

The strokes caused by hemorrhage are called intraacerebral and intraventricular hemorrhages. Subarachnoid hemorrhages, on the other hand, result from bleeding outside of the brain tissue. These blood clots can travel through the aorta or through the patent foramen ovale, a hole between the left and right upper chambers of the heart.

Post-stroke care can be extensive, and patients may require physical and speech therapy. Some patients may even require a feeding tube. Rehabilitation often begins in the hospital, and can continue in a rehabilitation facility. Speech pathologists, physiotherapists, and occupational therapists can help patients get back to normal. People with stroke often suffer from depression and are not motivated to complete physical rehabilitation. They may have personality changes as well, which can be distressing for family members.

The early diagnosis of a stroke is vital. The earlier treatment begins, the less likely the patient is to suffer severe brain damage. A doctor will be able to confirm the type of stroke and its symptoms. Once the diagnosis is confirmed, a stroke treatment plan can be designed and implemented. The sooner a stroke is treated, the more likely the patient will be able to regain function and normal life. This is possible through a combination of lifestyle changes, anticoagulant medications, and diet changes.

Some stroke warning signs include a drooping face, unusual smile, difficulty speaking, and speech problems. If you notice any of these symptoms, call 9-1-1 immediately. Stroke symptoms often occur suddenly and without warning. Patients may lose consciousness, develop a drooping face or arm, or lose control of their legs. Symptoms of a stroke may also include changes in vision, speech, or sensation.

The first test that doctors will perform after a stroke is a Cerebral Computed Tomography (CT) Scan. This scan uses X-rays to show the structure of the brain and to identify any bleeding. The scan will also determine the type of stroke and which part of the brain is affected. This type of imaging will allow doctors to determine the proper treatment and determine whether the symptoms are related to another illness. Other symptoms that mimic a stroke include migraine, seizures, and heart arrhythmias. The treatment options depend on the cause and can be short-term or long-term.

There are two types of stroke. One type occurs when a blood clot blocks a blood vessel in the brain. The clot can form in a blood vessel elsewhere in the body or within the brain itself. In ischemic stroke, the blood flow to the brain stops. The other type is hemorrhagic, which is caused by a burst blood vessel. The rupture of the blood vessel causes more damage to nearby brain tissue.

TIA symptoms are common and can occur months before the onset of a full-blown stroke. Although TIA symptoms are short-lived, they are warning signs of a potentially serious condition. If a TIA occurs, it’s imperative to seek medical attention immediately. A stroke is life-threatening and it’s important to act quickly. For example, if you feel numbness in one arm or leg, you may have a CVA stroke.

A stroke happens when a blood vessel in the brain bursts or narrows, preventing oxygen and nutrients from reaching the brain. During a stroke, the brain cells are not getting enough oxygen or nutrients, and begin to die after a few minutes of being without blood. It’s important to seek immediate medical attention, as these symptoms can lead to permanent brain damage. While many factors can increase your risk for a stroke, a healthy lifestyle and regular checkups can help minimize your risk.
