What is pyramidal syndrome? what causes it?

Neuromuscular: Pyramidal tract is the nerve highway of the body controlling most volantary muscle functions. Tumor, Bleeding, thrombosis, injury can cause disruption of the tract leading to dysfunction. Certain demyelenating / immunologic disease can cause short circuits in the tract also.

Resending answer:): The pyramidal tracts are tracts of nerve fibers that run from the brain to the brain stem or spinal cord to control muscle function in the body. If injured or altered, muscles show spasticity/spasm and weakness/wasting. Injury may be caused by stroke, brain hemorrhage, tumor, infection, inflammation such as from meningitis or multiple sclerosis, or trauma.
