A stroke occurs when blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and vital nutrients. In clinical neurology, we have a vital maxim: 'Time is Brain'. Immediate intervention directly dictates whether a patient makes a full recovery or suffers lasting disability.
Remember the 'BE-FAST' Warning Signs
- B (Balance): Sudden loss of balance, dizziness, or coordination difficulty.
- E (Eyes): Sudden blurriness or loss of vision in one or both eyes.
- F (Face Drooping): One side of the face sags or goes numb when attempting to smile.
- A (Arm Weakness): One arm drifts downward when both arms are raised.
- S (Speech Difficulty): Slurred speech, inability to articulate words, or strange phrasing.
- T (Time to Call): Rush immediately to a stroke-ready hospital equipped with emergency CT/MRI.
What is the 'Golden Hour'?
The first 4.5 hours from the initial onset of symptoms represent the clinical window for intravenous thrombolysis (clot-dissolving medication). Beyond this window, advanced neuro-interventional thrombectomy or surgical decompression may be necessary.
Never allow a stroke patient to 'sleep it off' hoping they will feel better in the morning. Immediate arrival at a 24x7 critical trauma facility saves precious lives.
