A Short Note On Transient Ischemic Attack

An ischemic stroke is typically caused by a thrombosis, which is a blood clot or an embolism, when the blood clot detaches and infiltrates the blood stream.

In many cases, strokes can be diagnosed, prevented and treatable. Symptoms of a stroke can occur quickly and may cause: sudden numbness, tingling, or weakness, or paralysis in your face, arm, or leg, especially on one side of your body. Sudden: vision changes, trouble speaking (slurred speech), confusion or trouble understanding simple statements, problems with walking or balance, severe headache. It's recommended to call a doctor or 911 even if these symptoms last for a short amount of time because a transient ischemic attack, or mini stroke may have occurred. The transient ischemic attack may be a precursor to a stroke occurring soon. Catching these symptoms can dramatically increase chances of prevention additional damage to the body (2).

A stroke occurs when the blood supply to the brain is blocked. The tissue does not get enough of oxygen and nutrients within minutes, the brain cells begin to die. A stroke is a medical emergency, and prompt treatment is crucial. The good news is a stroke can be treatable and is more preventable. More people live longer now than in the past years. Stroke is known as the silent killer. Many people ignore the symptoms and cause more damage to their body. People with stroke have trouble speaking and understanding, paralysis or numbness of the face arm or leg. If you ever encounter anyone with these systems, please call 911 imminently for help.

Often times, doctors will typically call a stroke a “brain attack” because the events that transpire resemble those that occur during a heart attack (Wang and Aamodt, 2010). Blood supplies a constant source of oxygen to the brain. However, a stroke occurs when that blood supply to any given part of the brain is suddenly ceased. If the blood supply to the brain is suddenly interrupted this leads to the deprivation of oxygen and glucose to that area. The brain cells that are prevented from acquiring these substances, especially oxygen, will be quickly killed off. Strokes can be categorized into two classes: Ischemic and hemorrhagic strokes (Lindley, 2008).

Sometimes known as a brain attack, a stroke occurs when blood flow to the brain stops. Brain cells immediately start to die due to the lack of oxygen and nutrients they need to function. There are two types of strokes. The most common type, called ischemic stroke, is caused by a blood clot that blocks a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke is the fourth leading cause of death for Americans ("What You Need to Know About Stroke," 2013). In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year ("Stroke Facts," 2015). A stroke can cause great damage in the brain and lead to mild or severe

A brain attack and a Transient Ischemic Attack are two things that should not be taken differently. They both have things in common, and they also have their differences. They both are types of strokes, but one is slightly different. A brain attack is a normal stroke, and has the normal side effects, but a TIA is called a “mini stroke” (. "Transient Ischemic Attack (TIA).") A TIA is a really quick thing, and does not cause any serious damage ("Transient Ischemic Attack (TIA).".

A Transient Ischemic Attack, generally referred to as a TIA, is a type of stroke that only last a few minutes. They are sometimes called ¡§mini-strokes.¡¨ The term transient is used to describe a condition that lasts only a short amount of time. Ischemic describes an inadequate blood flow. Therefore, TIA is a deprivation of blood to the brain for a short period of time.

A stroke can cause great damage in the brain and lead to mild or severe disabilities to the entire body such as paralysis, difficulties with

The cause of a stroke could be an artery that is blocked. It is also referred to as an ischemic stroke. A stroke could also be caused by a blood vessel that has burst or is leaking, which is known as a hemorrhagic stroke. Some can experience an interruption in blood flow through their brain, which is known as transient ischemic attack (TIA). Ischemic strokes are the most common. When an ischemic stroke happens, arteries to the brain get narrowed or blocked, which causes a dramatic reduction of blood flow. There are two types of ischemic strokes. One of them is called a thrombotic stroke. A stroke that is thrombotic takes place when a blood clot forms in an artery

Episode of cerebrovascular insufficiency with temporary episodes of neurologic dysfunction lasting less than 24 hours and often less than 15 minutes. Most TIA symptoms resolve within 3 hours. Symptoms lasting longer than 24 hours are classified as a stroke. TIAs are thought to be caused by microemboli that temporarily occlude blood flow resulting in ischemia of brain tissue. Often occurs in patients with carotid artery stenosis.

On July 12, Mrs. Smith had severe pain in the left side of her head while at work. She was not speaking coherently and eventually lost consciousness for a few minutes. She was taken to her physician’s office by a co-worker. Mrs. Smith’s physician suggested that she get some imaging tests at the hospital’s outpatient imaging center to rule out a transient ischemic attack. A medical assistant at the imaging center told Mrs. Smith that her tests could not be scheduled until July 14.

Recently, there has been a surge in reports of TIAs in rare instances such as healthy, young women. With lack of full understanding as to the reasoning behind this, research found that strokes are not a geriatric disease as once believed (stroke association.org). Accordingly, Steven J. Kittner, M.D., director of the Maryland Stroke Center at the University Of Maryland School Of Medicine in Baltimore declares that strokes can affect anyone at any age (2004). Furthermore, he states that although there are common risk factors, some of the more hidden ones are the most dangerous, especially for women under 55 (Kittner, 2004). He claims, matching other reports that these hidden risk factors leading to increased strokes include: migraines, oral contraceptives,

Transient ischemic attack (TIA) is a transient cerebral blood flow disruption, which affects a focal portion of the brain. TIA’s are brief temporary episodes of neurologic loss of vision, motor, and or sensory function that can last from a few minutes up to 24 hours. It cause by temporary obstructions of blood flow to the brain, and can be a warning sign of an impending cerebrovascular accident (CVA). Patients who experience a TIA will go on to have a completed stroke but having TIA increases the risk of stroke. Symptoms of TIA’s mirror those of a stroke but are temporary in nature and do not cause any irreversible damage. Signs and symptoms include a sudden weakness or parethesia on one side of the body, abrupt dimness or loss of vision especially

Based on the information in the case study, it is likely that Mrs Tim has suffered a Transient Ischaemic Attack (TIA). A TIA is when there is a temporary restriction to blood flow in the brain, which causes a deficit in neurological function (Koutoukidis, Stainton, & Hughson, 2013). The duration is anywhere between a couple of minutes through to 24 hours. The main causes of TIA’s are: an occlusion caused by a micro-emboli; arteriole spasm (Chang, Daly, & Elliott, 2006); or a small brain haemorrhage. Without the blood flowing, the brain cannot get the oxygen it needs and brain cells begin to die. However, once the blood flow is restored, oxygen is distributed and brain function is once again restored (National Stroke Foundation - Australia,

As briefly defined above, a cerebrovascular event or stroke is a disruption of blood supply to the brain. It is characterised by sudden and rapid developing signs of the affected artery or the disturbance of cerebral functions (Wiley-Blackwell, 2011). There are two types of stroke: Ischaemic and Haemorrhagic. Ischaemic stroke is caused by an obstruction of a blood vessel that supplies the brain, either by an in-situ thrombus or embolus from a site elsewhere, most common in the carotid artery (Wiley-Blackwell, 2011). Haemorrhagic stroke is
