According to the Health Service Executive (HSE), a stroke occurs when blood flow to part of the brain is either blocked or interrupted by a ruptured blood vessel. Without oxygen, brain cells begin to die within minutes, potentially leading to permanent disability or death. Medical experts stress that rapid treatment significantly reduces the risk of long-term damage.
In a recent social media advisory, the HSE reminded the public that stroke affects as many as one in four people at some point in their lifetime and can happen at any age. “The second you suspect a stroke is the second you dial 999 or 112,” the agency warned, urging people to remember the FAST method for identifying symptoms.
FAST refers to four major warning signs. Face drooping on one side, difficulty smiling, or a sagging eyelid may indicate a stroke. Arms weakness or numbness can make it difficult to lift or hold up both arms. Speech may become slurred, garbled, or completely impaired. Time is critical — emergency services should be contacted immediately if any of these signs are present.
Health authorities emphasize that recognising these symptoms is especially important for those caring for people in high-risk groups, including older adults and individuals with diabetes or high blood pressure.
In Ireland alone, approximately 7,500 people suffer a stroke each year. Despite this, fewer than half of patients reach hospital within three hours of symptom onset — a crucial window for treatments that can save lives and reduce disability. Medical data shows the brain loses around two million cells for every minute it is deprived of oxygen.
There are two main types of stroke: ischaemic, caused by a blood clot blocking a vessel, and haemorrhagic, which occurs when a blood vessel supplying the brain bursts. A transient ischaemic attack (TIA), often referred to as a “mini-stroke,” involves a temporary interruption of blood flow and can last from minutes to several hours.
Treatment options vary depending on the type and severity of the stroke, but may include medication to dissolve clots, control bleeding, manage blood pressure, and reduce cholesterol. Health officials continue to stress that speed is critical, urging the public not to delay seeking help if a stroke is suspected.
