Dr. Navdeep Kumar, MD(Medicine) DNB (Neurology)- Indogulf Hospital Noida

Stroke is a condition of brain and is often a misunderstood aspects in Neurology. When we say stroke, most consider it as Heart attack, but Stroke as a word is used to denote Brain stroke caused due to hidnerance of proper flow of blood in brain. Often Patients come and ask me many basic questions about stroke and I get tensed looking at the amount of wrong information they have about strokes. That’s why I am creating this short page description of the 4 key questions commonly asked and its point perfect answer. Hope it proves useful.

1. What is Stroke?

Strokes is attack in brain which occurs when the blood supply to the brain gets blocked. In the condition of stroke, the patient brain does not get enough oxygen or nutrient which it requires to function normally and the brain cells start to die. A stroke is a medical emergency that needs immediate medical attention.

2. What are the Various types of Stroked?

Strokes are divided into three main categories:
1. Hemorrhagic Stroke: When a weakened blood vessel ruptures and normally occur as a result of aneurysms or arteriovenous malformations (AVMs) it results into a Hemorrhagic stroke
2. Ischemic Stroke: The most common and widely affecting type of stroke is Ischemic stroke. During this ischemic stroke, a blood clot gets formed which hinders the normal flow of oxygen and blood to reach the brain. Ischemic stroke is caused because arteries which provide blood to brain starts getting blocked or starts narrowing resulting in a condition known as ischemic. Ischemia comes from a greek word iskhein: means keep back and Haima: means blood. Ischemic stroke as the doctors suggest is damage of brain cells due to severe reduction in blood flow. Fatty deposits within the arteries called plaque can cause clots that result in ischemia.
3. Transient ischemic attacks (TIAs): This has to do with the flow of blood to brain but not in the specific time. It’s also called mini stroke wherein normal blood flow resumes after a short gap and when it happens, the symptoms ceases to be visible.

3. What are the symptoms of Stroke?

Stroke appear without warning and one must take early precaution to get proper medical attention of it. The key symptoms of stroke are:
1. Inability to move specific part of leg, arm or face specially one side of body and or numbness in any specific part for prolonged period.
2. Issue with speaking, understanding and deciphering along with a sense of disorientation and confusion
3. a headache, possibly with altered consciousness or vomiting
4. Random dizziness, lack of coordination between body parts and facing some trouble walking normally.
5. The clarity in eyes gets a bit compromised - hazy visibility in one or both eyes.

Strokes usually end up as long term health issue and needs proper routine care. What is most crucial in condition of stroke and is often overlooked is the speed in which it is diagnosed and treated, because strokes can lead to permanent disability.

The following symptoms or problems are commonly seen in patients who suffered stroke.

  • Easily getting depressed and being sad.
  • Facing problems in expressing self, or controlling emotions which leads to emotional outbreak.
  • Pain in hand which change when temperature changes
  • Weakness or paralysis on one specific side of the body
  • Bowel control issues which can become acute.

4. What if you think the person is having Stroke?

Remember FAST

F- Face drooping: A slight droopiness in face- specifically on when side everytime the person smiles.

A- Arm Weakness: It’s advised to check the arm strength of the person who suffered stroke. When they will try to raise both their arms, one side of the arm will drift a little downwards.

S- Speech issue: A person who suffered a stroke will have their speech a little slippery and will face challenge in pronouncing the words correctly.

T- Time: Time is critical. The moment you witness these three symptoms- just contact the emergency service at your local city. If you are in Delhi NCR- You can contact - Indogulf Hospital by calling +91 9999369797


  • Physical examination: Take the patient and see a doctor. A good doctor will typically start by asking your medical history, what odd behaviours are visible and since when. The doctor will quickly check the vitals and do neurological checks.
  • Blood test: Complete blood test, blood count sugar test and other routine tests are advised. If the patient is young, a deeper probe is required to understand and identify the cause behind the stroke.
  • CT scan: CT - Computed Tomography, or CAT scans, are set of special X-ray tests that produce cross-sectional images of the body using X-rays and a computer. CT scans are also referred to as computerized axial tomography.What CT Scan does is shows conditions of tumors, hemorrhages, strokes, or any other conditions within the brain.
  • MRI scan: It uses magnetic radiations ( non harmful ) and different sequence to create images in various planes with high clarity. MRI usually identifies all types of strokes even when done within minutes of stroke. Indo gulf Diagnostics is considered among the best Diagnosis service in Delhi NCR and you can contact: 0120 475 2300 to enquire more about it or visit IndoGulfHospital
  • Carotid ultrasound: An ultrasound scan to check the blood flow in the carotid arteries and to see if there is any plaque present.
  • Cerebral angiogram: In Cerebral Angiogram, dyes are injected into the brain's blood vessels to make them visible under X-ray. This gives a detailed view of the brain and the blood vessels in the neck.
  • Echocardiogram: This creates a detailed image of the heart to check for any sources of clots that could have traveled to the brain to cause a stroke.
