Around minute twenty of reading, the lines start to swim and the same sentence gets read three times. That reading fatigue after 60 may be an early brain signal.
Most people blame their glasses or the lamp — and often that’s the real cause. But a 2001 autopsy study in Brain Research found the brainstem relay that drives your reading eye movements shows Alzheimer’s-related changes at the preclinical stage, before memory ever visibly fails. This video breaks down saccades, smooth pursuit, compensation under load, and the exact two-week log to bring to your physician.
