15 Warning Signs Of Cerebellar Degeneration

8. Dysarthria

Dysarthria refers to slurred or slowed speech caused by weakened or uncoordinated muscles used in talking. When the cerebellum can’t properly regulate the timing and strength of the tongue, lips, and vocal cords, speech becomes uneven—often described as “scanning” or “explosive.” Patients might speak in irregular bursts, have variable volume, or pause unexpectedly. Speech therapy is the cornerstone of management, teaching techniques to control breath support, pacing, and articulation. Augmentative communication devices can also aid those with severe dysarthria to ensure effective interaction.
