  • Abstract
  • Look Inside

We classify dysarthria into two forms; simple and special. The simple form of dysarthria shows consistent errors in articulation caused by motor paresis, while the special form of dysarthria shows intermittent or variable errors in articulation.

It is hypothesized that bilateral lesions in the lower motor cortex, which controls the oropharynx, larynx, and respiratory apparatus, interrupts movements of these muscle groups, resulting in simple form of dysarthria. It has not been firmly established, whether bilateral cortical lesions of the motor cortex alone produce the simple form of dysarthria.
