The symptoms described are consistent with early signs of amyotrophic lateral sclerosis (Lou Gehrig's disease), which is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to muscle weakness, stiffness, and eventually, paralysis. Parkinson disease typically presents with tremors, rigidity, and bradykinesia, while Huntington disease affects cognition and behavior as well as motor function. Alzheimer disease primarily affects memory and cognitive function, not motor function.
