Acute central nervous system (CNS) injury refers to sudden damage affecting the brain or spinal cord due to trauma, stroke, or other events. It can lead to neurological deficits and life-threatening complications. Causes include head injuries, strokes, spinal cord trauma, infections, or tumors. Symptoms vary widely depending on the type and location of the injury but may include paralysis, loss of sensation, impaired cognitive function, or altered consciousness. Diagnosis involves imaging tests, neurological assessments, and sometimes invasive procedures. Treatment aims to stabilize the patient, minimize further damage, and rehabilitate affected functions through medications, surgery, or rehabilitation therapy. Early intervention is crucial for improving outcomes.
