 Hello everybody. I am Dr. Sivanand Pai, a consultant neurologist from KMC Mangalore. So today we will be talking about stroke. See stroke means it usually happens suddenly. It is also called cerebrovascular accident. Usually patients can have two types of stroke. One is a ischemic stroke and a hemorrhagic stroke. Hemorrhagic stroke means the blood pressure increases and the blood vessel ruptures and produces bleeding into the brain parankaima. Another is ischemic stroke. There is a reduced circulation to the brain parankaima. So we will be focusing on mainly ischemic stroke. If the patient comes very early to a stroke center, we can give an injection called thrombolytic injection or thrombolysis treatment and patient symptoms can be reversed and we can reduce the mortality as well as morbidity. So patients with the ischemic stroke do have symptoms of by a mnemonic called FAST. That is F stands for the facial asymmetry. A stands for arm weakness. Like when they ask to abduct their hand because of the loss of power, the arm falls down. This is A of FAST. S is speech where they have problems with talking. The speech becomes not clear or they are not able to understand the speech and T stands for time. Time is brain. So any person who are having these symptoms like facial asymmetry or weakness of any of the limbs, either upper limb or lower limb, hand or the leg or there is a difficulty in understanding speech or not able to articulate, they have to immediately rush to a place where they have the facilities for treating stroke. When the patient comes to us within say 4.5 hours or sometimes up to 6 hours, we give an injection called thrombolytic treatment where we are able to give an injection through the IV mode and the clot does get laced and the patient symptoms get reversed and patients morbidity and mortality can be reduced.
