Akinetopsia
Akinetopsia (pronounced: a-kin-e-top-sia) is a rare neuropsychological disorder that affects the visual system. It is characterized by an inability to perceive motion in the visual field, despite being able to see stationary objects without issue.
Etymology
The term "Akinetopsia" is derived from the Greek words "a" meaning "without", "kine" meaning "to move", and "opsia" meaning "seeing". Thus, it literally translates to "without seeing movement".
Symptoms
People with Akinetopsia often describe their visual experience as akin to seeing the world in a series of still frames, much like a stop-motion film. This can make it difficult for them to perform tasks that require the perception of motion, such as crossing the street or pouring a cup of tea.
Causes
Akinetopsia is most commonly caused by damage to the middle temporal visual area (MT) of the brain, which is responsible for processing motion. This damage can occur as a result of stroke, brain injury, or certain neurological conditions.
Treatment
There is currently no cure for Akinetopsia, but treatment typically involves managing the symptoms and learning coping strategies. This may include occupational therapy to help with daily tasks, and the use of assistive devices such as walking sticks.
