Ranchi, the capital of Jharkhand, is currently experiencing a significant increase in brain stroke cases, with major hospitals reporting a surge in admissions attributed to the prevailing intense cold wave. Hospitals like Rajendra Institute of Medical Sciences (RIMS) are witnessing 10 to 15 brain stroke patients daily, a substantial rise from the 2 to 4 cases observed before winter. Similarly, Sadar Hospital has seen a 20% to 30% increase in stroke cases during the cold spell. Neurology experts emphasize that negligence in managing hypertension during extreme cold conditions is proving fatal. The sudden drop in temperature causes blood vessels to constrict, leading to elevated blood pressure and a heightened risk of serious complications such as brain stroke and cardiac events. Cold temperatures can also thicken the blood, further increasing the risk of clot formation and reducing oxygen delivery to the brain. A concerning trend highlighted by medical professionals is the rising incidence of strokes among younger individuals, specifically those aged 25 to 45 years. Previously, strokes were more commonly observed in people above 45. This shift is linked to uncontrolled hypertension, elevated cholesterol, and unhealthy lifestyle choices. Authorities in Jharkhand, including the Ranchi district administration and the India Meteorological Department (IMD), have issued cold wave advisories and yellow alerts for various districts, confirming the severity and persistence of the cold conditions. Doctors urge the public, especially those with pre-existing conditions like hypertension, diabetes, and heart disease, to take preventive measures, including staying warm, managing chronic conditions, and seeking immediate medical attention for any stroke symptoms, recognizing the critical 'golden hour' for treatment.
