Parkinson's disease is classified as which type of disorder?

Parkinson's disease is classified as a neurological disorder because it primarily affects the nervous system, particularly the brain's ability to control movement. It is characterized by the degeneration of neurons that produce dopamine, a neurotransmitter crucial for transmitting signals that coordinate smooth and controlled movements.

Patients with Parkinson's experience symptoms such as tremors, stiffness, and bradykinesia (slowness of movement), which are all indicative of underlying neurological dysfunction. The progression of the disease leads to more pronounced motor difficulties, and it can also affect non-motor functions, including mood and cognition, further underscoring its classification within the realm of neurological disorders.

In contrast, cardiovascular disorders involve the heart and blood vessels, musculoskeletal disorders pertain to the bones, muscles, and joints, and endocrine disorders are concerned with hormone-related conditions. Therefore, the distinct nature and symptoms of Parkinson's disease directly align with it being categorized as a neurological disorder.
