Symptoms of progressive supranuclear palsy (PSP) tend to start out subtly. Then over time they become more noticeable and severe. Often, the first sign is a problem with balance while walking. You may fall a lot or find that you feel a bit rigid or uncomfortable when you walk.
These are also early signs of PSP:
Becoming more forgetful and cranky
Having unusual emotional outbursts, like crying or laughing at unexpected times
Becoming angry for no real reason
Tremors in the hands
Difficulty controlling eye movements
Difficulty directing your eyes where you want them to go
Inability to control the eyelids, such as unwanted blinking or being unable to open your eyes
