Peripheral neuropathy, a condition characterized by damage to the peripheral nervous system (PNS), disrupts the vital communication between the brain, spinal cord, and the rest of the body. This leads to sensory deficits, motor impairment, and autonomic dysfunction. The PNS comprises a network of neurons outside the central nervous system (CNS), which control numerous bodily functions through intricate synaptic relationships. Historically, the brain has been recognized as a critical organ, with evidence of early interventions such as trepanation from prehistoric periods, indicating attempts to address neurological symptoms. Early anatomical descriptions provided insights into CNS functions, highlighting structures like the meninges and cerebrospinal fluid (CSF), essential for cognition, movement, and sensation. In diagnosing PNS disorders, symptom variation depends on the nerve damage's location and nature. Magnetic Resonance Imaging (MRI) is commonly employed to visualize nerves and detect abnormalities, with specific sequences such as diffusion-weighted imaging (DWI) or T2-weighted sequences optimized to enhance detection sensitivity. These abstract highlights advanced imaging methods and contrast agents in medical imaging for evaluating PNS conditions and monitoring nerve regeneration considering their pharmacotherapeutics.
