Parkinson's disease announces its arrival through your vocal cords long before it ever shakes your hands. The neurodegenerative loss of dopamine damages the incredibly complex motor control required for speech before it impacts gross motor movements. Artificial intelligence can now analyze voice recordings to detect microscopic, imperceptible breathiness, tremors, and articulatory rigidity. By simply listening to a patient hold a vowel sound, algorithms can catch the basal ganglia dying years before traditional clinical symptoms emerge.
