In 'Ek Din', released on May 1, Sai Pallavi portrays Meera, who experiences Transient Global Amnesia (TGA) after an accident. TGA is a rare condition marked by sudden memory loss, where individuals cannot form new memories (anterograde amnesia) or recall recent events (retrograde amnesia). The Cleveland Clinic notes that TGA episodes typically last between one to ten hours, with some lasting up to 24 hours. Affected individuals can still recognize family and friends and perform daily tasks but may appear confused and repeatedly ask the same questions. Common triggers for TGA include sudden immersion in water, strenuous physical activity, emotional distress, and certain medical procedures. While the condition mainly affects those aged 50 and above and those with a history of migraines, it does not lead to serious complications or long-term memory loss. Understanding TGA can help demystify its portrayal in films like 'Ek Din'.
