Brain Stroke

What is a stroke?

A brain stroke or a brain attack is a medical emergency and one of the most disabling diseases that are preventable in many forms. It is said that 1 in every 6 or more Indians is at risk of brain stroke.

Earlier, we used to see strokes to be more common in the elderly but unfortunately, now, it is not the same as it used to be and we are seeing more younger people also being affected by it. 

A stroke occurs because of stoppage of blood flow to a certain region of the brain which may be due to:

  • Ischemic stroke: It happens when a blood vessel is blocked by a blood clot or a buildup of fatty deposits and cholesterol.
  • Hemorrhagic stroke: When a blood vessel bursts in the brain it causes blood spilling into nearby tissues. Due to this, pressure builds up in the nearby brain tissue causing damage and irritation.

 Since constant blood flow is needed for brain cells (neurons) to function, even a few minutes, as less as 3-5 minutes without adequate blood and oxygen to neurons can kill them. Due to neuronal death, the function they are responsible for also gets lost.

Brain Stroke can affect parts of the brain responsible for essential functions like breathing and blood pressure control besides other vital control centers and thus, if they are involved, it can cause death. 

Stroke is the second leading cause of death worldwide. While the number of people affected by stroke is increasing, the deaths are reducing in places with good medical care facilities. 

Who is at an increased risk of a brain stroke?

Various factors increase the risk of having a stroke:

  • High blood pressure
  • Heart disease
  • Diabetes
  • Smoking
  • Medications like birth control pills
  • High Blood Cholesterol
  • Lack of Exercise
  • Alcohol and Illicit Drug Use
  • Hereditary Causes of Genetic Mutations
  • Older Age Groups
  • Having a Previous Stroke
  • Aneurysm in Brain
  • Arteriovenous Malformation in Brain
  • A clot in veins of Brain (Venous Sinus Thrombosis)

What happens in a stroke?

The effects of stroke are wide depending upon the area of the brain affected and the severity of the stroke. It may impair your ability to:

  • Move
  • Speak
  • Eat
  • Think and remember
  • Control your bowel and bladder
  • Control your emotions
  • Control other vital body functions

Other less common symptoms of stroke may include:

  • Sudden nausea or vomiting not caused by a viral illness
  • Brief loss or change of consciousness, such as fainting, confusion, seizures, or coma
  • Transient Ischemic Attack (TIA), called a mini-stroke. A TIA can cause many of the same symptoms as a stroke. But TIA symptoms are passing. They can last for a few minutes or up to 24 hours. It may be a warning sign that a stroke is about to occur. But not all TIAs are followed by a stroke.

How to identify a brain stroke?

Unfortunately, life and optimum function can be saved in this catastrophic event only by early recognition followed by rapid and adequate treatment, at a centre equipped for stroke with a well-trained stroke team. 

The patients do not seek medical attention on their own because they lose the appreciation that something is wrong with them or they lack the knowledge of how acute treatment can be beneficial for them. 

It is often a family member or a bystander who calls for help. Therefore, please recognize early signs, as it may help a victim in your known circle, or even a bystander. Remember, A stroke can happen to anyone at any time.

  1. Imbalance 
  2. Sudden blurring of vision
  3. Asymmetric of face
  4. Acute onset weakness of arm or legs
  5. Slurring of speech

What are the treatments for a stroke?

A brain stroke requires proper medical evaluation and timely treatment. Taking a prompt treatment action for a stroke is vital for recovering from it. As per the American Heart Association, “Time lost is brain lost.” 

Dr. Vikas Gupta is one of the first neurosurgeons in the country with 20 years of experience in leading a stroke team to adapt new scientific methods after worldwide trials* to successfully treat stroke which involves opening up blocked artery in a neurovascular cath lab to open the blocked artery in an ischemic stroke (clot in an artery) called mechanical thrombectomy or block the ruptured brain artery by filling it and blocking it with coils, flow diverters and flow disruptors. 

Dr. Gupta says that when a victim of acute stroke reaches in the window period, he/she is rapidly evaluated and various imaging and brain scans were done using different modalities are employed to decide the appropriate therapy depending on the type of stroke (ischemic or hemorrhagic). The exact site affected is identified along with the blood vessel involved and the severity of the stroke. According to these factors and the standard scientific treatment guidelines, the patient is given intravenous thrombolytic (a clot-busting drug given via veins) or mechanical thrombectomy is done by an endovascular surgeon in the Neurovascular Cath lab. 

Along with specific treatment, utmost care is taken by the specialized and dedicated team to prevent further damage to the brain by giving neuroprotective medicines, decreasing the increased pressure in brain and brain swelling, preventing seizures and taking care of vital functions like breathing (with help of a ventilator), blood flow across the body, blood pressure, fluid and nutritional needs of the patient. 

Dr. Gupta truly believes that timely treatment is a game-changer in this disease with grave outcomes of probably a life of physical dependence or even death, to very gratifying outcomes.

Time being the key, the patient should reach the right hospital at earliest for the treatment to show optimum results. With every minute of delay, outcomes become worse.

What is life after a stroke-like?

The impact of a stroke depends on part of the brain affected and the amount of damage occurred. A team of different specialists including physiotherapists, psychologists, psychiatrists, speech and language therapists, dieticians helps the patient rehabilitate after the stroke.

Many people who have a stroke are left with paralysis of one of their limbs or improper speech. 

Other problems can include having trouble with:

  • Thinking
  • Speaking and understanding
  • Reading 
  • Eating by themselves
  • Swallowing
  • Doing simple calculations
  • Dressing themselves
  • Showering
  • Going to the bathroom
  • Control of bladder and/or bowel

Some people may need lifelong assistance to carry out their daily activities and take care of their hygiene.

Dr. Vikas Gupta is a very good neurosurgeon. We are very satisfied with his stroke treatment for my mother. We were scared initially when our mom suffered from a brain stroke but Dr. Vikas assured us that with the help of surgery, she would be better. It’s been 3 months since her surgery and she is recovering well.

Dr. Vikas is one of the best neurosurgeons that I know of. I visited him for my father’s brain surgery and like always, Dr. Vikas didn’t disappoint. The surgery was successful and my father has almost recovered from it. Thank you doctor for your guidance and support.
