Q: What is a stroke?
Ans: Stroke is a brain attack which occurs when there is a blockage in the blood supply to brain. Due to the interruption in blood supply, the brain does not get sufficient oxygen or nutrients which in turn cause the brain cells to die.
Q: How many types of Strokes are there?
Ans: There are mainly two types of strokes; Haemorrhagic or Ischemic. Haemorrhagic stroke is caused by a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. On the other hand, Ischemic stroke occurs when an artery to the brain that carries oxygen and nutrients through blood is blocked due to blood clot.

Q:What is Window Period?
Ans: Every second is important in stroke. Within a second billions of brain cells can get damaged and once they are damaged, they cannot be repaired fully. But remember, within 4 and half hours of stroke if you admit the patient to a proper set-up and start thrombolysis treatment, there are possible chances for less brain damage and lesser disability of the patient. This 4 and half-hour’ time period after stroke is known as Window Period.
Q: What is Thrombolytic Therapy?
Ans: In case of ischemic stroke, Tissue Plasminogen activator injection is administered within 4.5 hours of the onset of symptoms to dissolve the clots and revive the normal blood supply to brain with the clot busting injection, this is called Thrombolysis therapy. Giving thrombolysis in right time can help patient recover soon and limit damages and disabilities related to Stroke. Often pateints with paralysis too can be seen recovering from this therapy.
Q: Is there any connection between COVID 19 & Stroke?
Ans: Recent ICMR guidelines state that corona virus can also affect the central nervous system. A recent study from North-western University in the United States says that symptoms such as convulsions and strokes can also be seen in COVID positive patients.
Coronavirus is an RNA virus that infects the human body rapidly by increasing the ‘viral load’ and possibly leading to an ineffective immune response. This results in the dysregulated activation of Coagulation Cascade in the affected person’s body. In simple words, blood begins to clot in different parts of our body. Blood clots form in the veins and sub-veins of the lungs, heart and even the brain. As a result, older patients with COVID 19 infection often suffer from heart attacks, strokes or pulmonary thrombosis.
