Which type of dysarthria is often linked with neurological disorders like ALS?

• A. Flaccid dysarthria
• B. Spastic dysarthria
• C. Ataxic dysarthria
• D. Hyperkinetic dysarthria

Answer: (B)

Spastic dysarthria is correctly identified as being associated with neurological disorders like Amyotrophic Lateral Sclerosis (ALS). This type of dysarthria results from bilateral damage to the upper motor neurons, leading to increased muscle tone and spasticity. The characteristics of spastic dysarthria include a strained-strangled voice quality, imprecise articulation, and difficulties with prosody. These features stem from the overactivity of muscles involved in speech production, which can occur in conditions that affect the central nervous system, including ALS.

In the context of ALS, as motor neurons degenerate, the resulting impact on muscular control aligns with the characteristics observed in spastic dysarthria. This makes it essential to recognize and understand the implications of spastic dysarthria for effective assessment and intervention in patients with such neurological conditions.
