The blood-brain barrier is a selective permeability barrier that protects the central nervous system from potentially harmful substances in the bloodstream while allowing essential nutrients to pass through. It is crucial for maintaining the brain's stable environment, but it also poses challenges for drug delivery to treat neurological disorders.

The central nervous system (CNS) is the primary control center for the body, consisting of the brain and spinal cord, and it processes and coordinates sensory information and responses. It plays a crucial role in regulating bodily functions, cognition, and behavior, making it essential for survival and adaptation to the environment.

Neurological disorders encompass a wide range of conditions affecting the nervous system, including the brain, spinal cord, and peripheral nerves. These disorders can result from genetic, environmental, or unknown causes and may lead to a variety of symptoms such as cognitive impairment, motor dysfunction, and sensory disturbances.
