Definition
Disorders of the Nervous System: The disorders of the nervous system may be classified as vascular, infectious, structural, functional and degenerative. While classifying, the site of involvement is also considered.

Infectious — due to infection
Structural — due to structural abnormalities
Functional — due to functional abnormalities
Degenerative — due to degeneration
Core Concept

Infectious disorders = caused by infectious agents
Structural disorders = abnormal mass of neurological cells
Functional disorders = pain without structural cause
Degenerative disorders = degeneration of nervous system
Stroke = vascular disorder
