Vision, one of our most essential senses, is often thought of in purely mechanical terms: light enters the eye, the brain processes the image, and we see. But when the brain begins to deteriorate—as it does in neurodegenerative conditions like Alzheimer’s disease—the impact on vision can be profound and multifaceted. While memory loss tends to dominate conversations around Alzheimer’s, emerging research reveals that visual processing issues may serve as some of the earliest signs of cognitive decline. Recognizing these symptoms is crucial for early intervention. Indeed, weird vision problems in early Alzheimer patients are no longer considered anomalies, but increasingly understood as indicators of deeper neurological dysfunction.
