Other Names: Mini stroke

A transient ischemic attack (TIA) is a stroke that comes and goes quickly. Occurs when a blood clot blocks a blood vessel in the brain. That makes the blood supply to the brain to pause. Symptoms of a TIA are similar to symptoms of a stroke or a stroke, but its duration is less. Occur suddenly and include:

* Numbness or weakness, especially on one side of body
* Confusion or trouble speaking or understanding
* Trouble seeing in one or both eyes
* Loss of balance or coordination of movements

Most TIA symptoms disappear within an hour but can last up to 24 hours. Because you can not tell if symptoms are due to a TIA or stroke, you should go to a hospital quickly. TIAs are often a warning sign of future spills. Taking medicines such as anticoagulants, may reduce the risk of stroke. The doctor may also recommend surgery.

A stroke is a medical emergency. Strokes occur when blood flow stops the brain. In just a few minutes, brain cells begin to die. There are two types of stroke. The most common type, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a ruptured blood vessel that bleeds down into the brain. The “mini-strokes” or transient ischemic attacks, occur when the blood supply to the brain is briefly interrupted.

The symptoms of a stroke are:

* Sudden numbness or weakness in the face, arm or leg (especially on one side of the body)
* Sudden confusion, trouble speaking or understanding
* Sudden trouble seeing in one or both eyes
* Sudden trouble walking, dizziness, loss of balance or coordination of movements
* Sudden headache with no known cause, severe

If you have any of these symptoms, you should quickly go to a hospital to get treatment. Acute therapy for stroke is to stop the spill dissolving the clot or bleeding control. The post-stroke rehabilitation helps individuals overcome disabilities caused by the spill. Drug therapy with anticoagulants and antiplatelet agents is the most common treatment for stroke.

A cerebral aneurysm is a widening in the wall of an artery in the brain. Sometimes they are so small as a raspberry. Most cerebral aneurysms do not show symptoms until they become large, begin to bleed or rupture.

If a cerebral aneurysm presses on the nerves in his brain, can cause symptoms. These may include:

* A drooping eyelid
* Double vision or other vision changes
* Pain above or behind the eye
* A dilated pupil
* Numbness or weakness on one side of the face or body

Treatment depends on the size and location of the aneurysm, if it is infected or has ruptured. If a cerebral aneurysm ruptures, symptoms may include sudden headache, nausea and vomiting, stiff neck, loss of consciousness and signs of a stroke. Any of these symptoms requires urgent medical attention.

There are four main types:

* Expressive aphasia: the patient knows what you mean, but has difficulty to say or write
* Receptive aphasia: voice is heard or read a form, but does not find meaning to what they read or hear
* Anomic aphasia: has difficulty using the right words to describe objects, places or events
* Global aphasia: a patient can not speak, understand what they are told, read or write

Some people recover from aphasia without treatment. However, most need speech therapy as soon as possible.
