Causes, Risk Factors, And Complications Of Progressive Supranuclear Palsy

Increased Risk Of Injuries

One of the earliest symptoms reported in progressive supranuclear palsy is a loss of balance when they are trying to walk. The risk of injuries is increased in affected individuals because when they experience a fall, it tends to occur in the backward direction. Progressive supranuclear palsy patients also tend to have issues with their behavior and abnormally poor judgment skills. Some may act recklessly or take unnecessary risks. Some individuals affected by progressive supranuclear palsy may experience the manifestation of the involuntary movements of particular parts of their body, which can put them at an increased risk of injury when they attempt to use tools, scissors, utensils, and other objects. Blurry or double vision in an affected individual due to their disorder can put them at a higher risk of injury if they attempt to operate machinery or drive a vehicle.

Trouble Looking At Lights

The ocular and visual symptoms that present in affected individuals are the main distinguishing factor of this disorder, as Parkinson's disease patients have many of the same symptoms. There are several reasons why an affected individual may have trouble looking at lights, including the impaired ability to move the eyelids at the proper times. Excessive dryness due to a reduced rate of blinking of the eyes can cause an individual with progressive supranuclear palsy to be extra sensitive to lights. A progressive supranuclear palsy patient can experience problems with looking at lights after they have developed an increased sensitivity due to problems with gaze control. When an affected individual cannot shift their gaze out of bright lights properly, they may sustain damage to the parts of the eye responsible for adjustments to brighter lighting conditions.
