Shy-Drager syndrome is a degenerative neurological disorder that
affects your brain and other parts of your central nervous system.
It causes a drop in blood pressure when standing up, bladder
dysfunction and other Parkinson's-like symptoms, such as slowness
of movement, muscle rigidity and poor balance. Shy-Drager syndrome
develops in adulthood, beginning at an average age of 50 years, and
is gradually progressive and usually fatal. A rare condition,
Shy-Drager syndrome occurs about two to three times more frequently
in men. Shy-Drager syndrome is named after two researchers who
first described it in 1960. It's commonly referred to as multiple
system atrophy (MSA).
