In a rare form of Alzheimer’s disease, people may go to the eye doctor first, complaining that they can’t see right. That’s because posterior affects areas in the brain that are responsible for spatial perception, and complex visual processing, as well s spelling and calculation.
Bob Yetz says reading is very difficult for him because sometimes the letters just kind of meld in together. But at UC Health Eye Center, Neuro-opthalmologistt Dr. Victoria Pelak says his eyes are healthy. His retina and optic nerve all look to be in good shape.
But Bob’s brain is not. He has Alzheimer’s disease, a rare form called posterior cortical atrophy or PCA. It affects the back part of the brain.
Dr. Pelak says, “Just like Alzheimers affects memory areas, that part of the brain that is important for vision is degenerating because of alzheimer’s disease
Bob has difficulty interpreting what he’s seeing. He struggles with judging distance and may walk into door frames. He has trouble finding things even though they’re in front of him, he has to be careful walking.
Bob remains positive and wants to share his struggle so others know they are not alone.
There’s no cure for Alzheimer’s or PCA. It’s estimated that PCA affects five percent of Alzheimer’s patients.
