Neuroprotection: approaches, evidence and risks

Neuroprotection aims to reduce secondary damage following the initial spinal cord injury. The initial mechanical damage and the subsequent biological response are separate stages of injury.

Inflammation, swelling, impaired blood flow, and related processes can damage additional nerve tissue. Inflammation can aid healing, but excessive or prolonged responses can also injure healthy tissue.

Medications and other approaches are under investigation; most remain experimental. Approaches include medicines and cooling, alongside treatments studied for specific injury mechanisms.

Complex injury mechanisms and lengthy testing make effective treatments difficult to establish. Animal findings must translate into safe human treatments through several phases of clinical research, requiring considerable time and resources.
