-audible inspiration
-short phrases
-hypernasal, nasal emission
-rapid and progressive weakness with use; recovery with rest
Spastic Dysarthria
Damage: bilateral damage to upper motor neurons

-Decreased swallowing, drooling
Hyperkinetic Dysarthria
Damage: Basal ganglia
Characteristics: forced and sudden inspiration or expiration
voice tremors, inconsistent articulation problems: impercise consonants, distorted vowels
-Facial tics, chorea, severe contracting spams, dystonia
Ataxic Dysarthroa
Damage: Cerebellar System
