Simultagnosia is a Visual Processing Disorder (VPD) wherein the brain struggles to interpret visual information despite normal eyesight, impacting reading, writing, and spatial awareness. It exists in the tension between the global and the local.
Dorsal
Difficulty perceiving multiple objects simultaneously. Airports, train stations, and grocery stores become visually exhausting rather than functional.
Ventral
Difficulty integrating parts of a single object into a coherent whole. You see components clearly but cannot assemble the complete entity.
Those with this condition often describe the world as filled with visual pollution—a relentless roar of flyers, ads, stickers, labels, and warnings. Backgrounds drown foregrounds. The familiar becomes uncanny. You feel "lost in space" even with perfect vision.
"I never considered myself disabled. Just... different."
