Study Reveals Long COVID's Impact on IQ and Cognitive Decline
A study published in the New England Journal of Medicine has found that long COVID may lead to a reduction in IQ by up to six points, with those experiencing symptoms for around 12 weeks showing the largest decline. The research, conducted by experts at Imperial College London, revealed that cognitive deficits associated with COVID-19, commonly referred to as brain fog, can be objectively measured and may affect memory, reasoning, and executive function. The study also suggests that earlier cases of the virus or its alpha variant were associated with more significant cognitive decline, while vaccination may provide some cognitive advantage. Experts warn that even small cognitive deficits can have a substantial impact on individuals' ability to work and function, making the long-term effects of COVID-19 particularly worrisome.
