Tests & Diagnosis
Progressive supranuclear palsy (PSP) is often hard to diagnose because its symptoms can mimick those of other, more common movement disorders. It may also be hard to diagnose because some of the most characteristic symptoms may develop late, or not at all. The key to diagnosing PSP is identifying early gait instability and difficulty moving the eyes (the hallmark of the disease), as well as ruling out other conditions, some of which are treatable.

- Visual complaints including blurred vision, difficulty looking up or down, double vision, light sensitivity, burning eyes, or other eye problems
