Do You know about TIS (Transient Ischemic Attack)?

 I have seen such a patient in Delhi when I took my MMA for a checkup purpose. During that period, my father's friend was in charge. Thus, I got to know about TIS. Uncle gave me a brief description of the TIS and made me understand the difference between TIS and Stroke. You will get to know about it, kindly read the whole blog.

Transient Ischemic Attack (TIS) is generally known as a ministroke. It is a brief episode of neurological dysfunction that is caused by loss of blood flow (ischemic) in the spinal cord, brain or retina, without any infarction (tissue death). TIS have a similar mechanism as an ischemic stroke because both are occurred by disruption in cerebral blood flow (CBF), or blood flow to the brain. TIA is generally classified by the duration of neurological symptoms.



It is quite odd to think out that sudden blockage of blood supply anywhere. As we know, from head to toe, our blood delivers oxygen to each part of our body, because it is essential to survive. If any case our blood flow gets blocked anywhere then it ultimately brings big trouble. One major serious effect of this situation is a transient ischemic attack (TIA for short).

 When anyone of us has a TIA, then the flow of the blood to our part of the brain gets blocked for a short period. It is known as a ministroke, but take it serious mini (TIA) because it can be a sign that a full-blown stroke is on the way. Almost 1 in 3 people suffers from TIA and go on to have a stroke, often within a year.

However, TIA is short that will not cause major damage but still need to treat as an emergency. This stroke is part of FABRY Disease.

Causes of TIA

TIA happens because the blood clot gets stuck in an artery that is responsible for supplying blood to the brain. In the absence of blood flow, a person brain with TIA starves for oxygen and cannot work promptly like it does. Just because of this they get symptoms like slurred speech or muscle weakness.



Clot refers to a build-up of a waxy or fatty substance known as plaque in arteries. They can take shape anywhere in the body and float anywhere until they get lodged somewhere. It is quite obvious if that somewhere happens to be an artery that directly goes to the brain, we can have a TIA.

Difference between TIA vs Stroke

I know now the question arises in your mind like how is a TIA different from the main stroke. I also had such a query when I was thinking about it. Let’s brief out--------------------------------------------------------------------------------------------------------

The major difference is that TIAs occurs only lasts a few minutes. The clot gets pushed along like a temporary clog in the artery or in other words, the chemical in the body quickly breaks it down. Thus, normal blood flow returns to the brain before any serious issue occurs. Such symptoms may last up to 24 hours but they generally go around within an hour.



On the other hand, strokes are do not go away too abruptly. There is some part of the brain that goes without oxygen and longer than last which brings more damage. While TIA comes on, goes away and does not leave any symptoms. Stroke generally bring long-lasting effects and can be life-threatening.

Symptoms of Mini-Stroke

·       ·       Trouble seeing in one or both eyes
·       Difficult in walking
·       Trouble in speaking or understanding
·       Loss of balance or coordination
·       Dizziness and numbness or weakness, especially on one side of the body

However, most of the symptoms of a TIA disappear within an hour, although it may last up to 24 hours. TIA is often a warning sign for future stroke, so, it is crucial to go to the hospital right away. Taking medication like blood thinner can decline the risk of a stroke.

Diagnosis and Tests

Carotid Ultrasound Imaging and Magnetic Resonance Imaging are the tests that are performed to check artery function, brain activity etc. Cardiac rhythm monitoring is also performed to understand blood flow in the whole body. In addition, these tests assist to capture blood clots, caused by ministroke takes place.

 

Treatment and Therapies

Antiplatelet medication This medication helps to stop stroke after the high risk of TIA within 10 to 21 days. Medications are aspirin in combination with extended-release clopidogrel.

In addition, anticoagulants, blood pressure control, cholesterol control and diabetes control are also used to reduce the risk of stroke or death after TIA.

 

TIA is highly prevalent for women who

·       Are pregnant, since pregnancy can raise their blood pressure, and make their heart work harder.

·       Take birth control pills, especially if they smoke or have high blood pressure

·       Use hormone replacement therapy to diagnose menopause symptoms.

 

Prevention of TIAs

To prevent TIAs, it is essential to bring fewer changes in our lifestyle such as

  • Numbness or weakness, especially on one side of the body
  • Trouble seeing in one or both eyes
  • Difficult in walking
  • Trouble in speaking or understanding
  • Loss of balance or coordination
  • Dizziness 

Such small changes help to reduce the risk of TIAs. Guys, I requested to all of you lease take of your health and bring several changes in our lifestyle to live healthy long-lasting.

 

Stay Happy! Stay Long Live

Best Wishes for the future! 😇😇😇😇✌

2021: Another year of triumph, or year of confusion?

    2021: Another year of triumph, or year of confusion? Is this the right title or not? As all we aware about 2020, it did not go away as we all planned. A worldwide covid-19 pandemic closed us in place, closing many businesses, social lives down and our businesses for good. Awfully, most of the people did not have any idea what to do with this situation or tackle this pandemic. Instead of amalgamating together as a country or more broadly as a world, we completed becoming even more isolated, due to several reasons i.e. nature of the virus itself, but merely because of the way that our political and cultural conversation has headed. As we were not enabled to put off these differences that’s why it cost us greatly. Just because of this, another year of our lives away from the family, another year of wasted time for most of us not to gain our defined goals. More shockingly, another year with the strange relationship between god and the temple. Temple is not required to co...

Do you know about Olfactory Neuroblastoma ?

Image
Olfactory neuroblastoma is a type of tumour that grows in the nasal cavity that is also known as esthesioneuroblastoma. The nasal cavity is one of the sensitive areas that contain nerves and other tissues which are responsible for the sense of smell. Such kind of tumour begins in the nasal cavity that grows into the nearby brain and eyes gradually. Tread his type of tumour can also spread to other body parts i.e. neck, lungs and bones. However, it is a rare type of cancer, making up only 3% of nasal cavity tumour cases. Such tumour affects only about 1 person per 2.5 million each year. It tends to occur in people between ages 10 to 20 years old and 50-60 years old. In the research, it has been found that adults are highly prevalent at risk because if they expose to harmful chemicals and specifically at work or in other ways. There are some possible causes include flour, nickel, cadmium dust, glues, formaldehyde, wood dust and other solvents. Tobacco and smoke are also risk factors for...

Extracorporeal membrane oxygenation (ECMO)

Image
Extracorporeal membrane oxygenation (ECMO )  is a cardiopulmonary support machine. It is quite similar to the heart-lung by-pass machine that is used in open-heart surgery. It is an artificial machine, by which patients’ blood pumps and oxygenates outside the body. It allows the lung and heart to rest. When any patient's heart is not capable to pump blood outside that situation, ECMO connects to the patient that assists in blood flowing through tubing to an artificial lung in the machine. Additionally, this machine adds oxygen and takes out carbon dioxide, later on, the blood warms to body temperature and pumps back into the body. Ty pes of ECMO Do you know? there are two types of ECMO i.e. VA ECMO and W ECMO. VA ECMO connects to both vein and artery. Now the question is what is the use of it. It uses when there is a problem with both the heart and lungs. On the other hand, W ECMO is used only in the lungs. This system connects to one or more veins, usually near the heart. What i...
