What neurological disorder is characterized by the gradual loss of motor function?

Parkinson's Disease is recognized as a neurological disorder marked by the gradual degradation of motor functions. This condition primarily affects movement control, leading to symptoms such as tremors, stiffness, slowness of movement, and balance problems. The hallmark of Parkinson's is its progressive nature, meaning that motor function tends to decline over time, often impacting daily activities and quality of life.

In contrast, epilepsy is primarily characterized by recurrent seizures due to abnormal electrical activity in the brain, while meningitis involves inflammation of the protective membranes surrounding the brain and spinal cord, and narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks, rather than a gradual loss of motor function.
