TIA (Transient ischaemic attack)
A transient ischaemic attack (TIA), or 'mini-stroke', is caused by a temporary fall in the blood supply to part of the brain, leading to a lack of oxygen to the brain. This can cause symptoms that are similar to a stroke, although they don't last as long. A TIA lasts only a few minutes and is usually resolved within 24 hours.
The main signs and symptoms of a TIA can be remembered by the word FAST: Face-Arms-Speech-Time:
Face. The face may have fallen on one side, the person may not be able to smile, or their mouth or eye may have drooped.
Arms. The person with suspected stroke may not be able to raise both arms and keep them there, due to arm weakness or numbness.
Speech. There may be slurred speech.
Time. It is time to call for an ambulance immediately if you see any of these signs or symptoms.
If signs and symptoms last longer than 24 hours, it is regarded as a full stroke.
Unconsciousness following a TIA would indicate an immediate urgent need to seek medical attention. However, falling unconscious does not always occur.
How common are TIAs?
It's difficult to know exactly how common TIAs are, as many people who have TIA symptoms do not seek medical help. Approximately one person per 1,000 in the population is thought to suffer a TIA each year. On average, a doctor sees three to five cases per year, and an average hospital manages around 1,000 cases.
A TIA is a true medical emergency
If you have the symptoms of a TIA, seek medical attention urgently. TIAs are a warning sign that further TIAs, or a full stroke, may be imminent.
Without treatment, there is a one in 10 chance that you will have a full stroke within four weeks of having a TIA. A stroke is a serious condition and can cause permanent disability. In some cases, strokes can be fatal.
As TIAs are serious, it is important that they are always investigated so that appropriate treatment can be given quickly. With treatment, the risk of a further TIA or a full stroke can be greatly reduced.

A seizure is caused by excessive electrical activity in the brain. A transient ischaemic attack is due to a problem in the blood supply to the brain. They are two very different kinds of problems. A seizure would not cause a problem in the blood supply to the brain and so it would not cause a TIA.
Normal saline is usually used when the reason of unconsciousness is unknown. The use of fluids is limited to normal saline and ringers lactate, or lactated ringers is used for fluid replacement in the case of blood loss as it acts as a volume replacement, keeping the blood pressure up.
Usually in the United States have the most earthquakes but, if you live there, don't worry 'cause they're usually harmless.
Usually cooling will cause solids to contract. That is, they will get slightly smaller.
Yes, TIA (transient ischemic attack) can sometimes cause temporary unconsciousness, which typically lasts for a short period of time, often just a few seconds or minutes. It is considered a warning sign of a potential stroke and should be evaluated by a healthcare provider.
TIA does not cause unconsciousness.

Yes, Tia is a Spanish name. It means "aunt" in Spanish.
Tia isn't a Dutch name or word, so it doesn't mean anything in Dutch.Tia is usually a short form of names ending with -tia, such as Letitia or Clementia. Tia is also the word aunt in Spanish and Portuguese.
Unconsciousness, also known as passing out, knocked out, or blacked out, is a state in which the rational mind cannot receive sensory input, or interact with others through the normal means of communication. Although the autonomic bodily functions (heartbeat, breathing) may continue, there is no conscious or willful control of the muscular system. Usually there are no memories formed during actual unconsciousness. It can be caused by physical problems in the brain, by concussion, or by the use of drugs. A sustained period of unconsciousness is called a "coma".
Alcohol can cause these three symptoms, if the dose is sufficient.
Anticoagulants serve to prevent clots from forming or becoming larger. During a TIA, a small blood clot has usually gotten itself stuck somewhere in the brain. TIA's usually pass, but without an anticoagulant it is possible that the clot could "snowball" into something much larger that could become stuck and cause a full on ischemic stroke. Therefore, anticoagulants help prevent TIA's & Strokes, and also minimize their effects to some extent.
