Gabapentin might help in several ways: 1. Reduces neural over-excitability → smoother signal flow in speech-motor networks. 2. Calms autonomic arousal → lowers the internal “pressure” that can trigger breath-holding or blocking. 3. Decreases muscle tone and spasm → especially in laryngeal and respiratory muscles. 4. Improves sleep and anxiety → indirectly improves fluency by stabilizing neurotransmitter balance.
