Neurological Sequelae After Electrical Injury

Electrical injuries are often evaluated based on visible burns or musculoskeletal damage. However, from a neurological perspective, electrical exposure represents a significant neurobiological insult that can result in lasting dysfunction—even when external injuries are minimal and imaging studies appear normal.

Electrical current interacts directly with excitable tissues, particularly neurons. Unlike blunt trauma, electrical injury may disrupt neurological function without producing overt structural lesions.

Key mechanisms include:

• Disruption of neuronal cell membranes

• Altered ion channel function affecting signal transmission

• Excitotoxic injury from abnormal neurotransmitter release

• Metabolic dysfunction impairing neuronal recovery
  

These mechanisms closely resemble those seen in traumatic brain injury (TBI), especially in mild and moderate cases.

Can affect both:

• Central nervous system (CNS): leading to cognitive, balance, and behavioral symptoms

• Peripheral nervous system (PNS): resulting in sensory changes, neuropathic pain, weakness, or autonomic dysfunction
  

Symptoms may be delayed, evolve over time, or fluctuate, reflecting ongoing neuroinflammatory and metabolic processes rather than a static injury.

Why Imaging May Appear Normal

CT scans and standard MRI are designed to detect macroscopic structural damage. Electrical injuries, however, frequently produce microscopic and functional abnormalities—disrupted neural connectivity and metabolic impairment—that fall below the resolution of routine imaging.

As a result, normal imaging does not rule out neurological injury following electrical exposure.

Common Neurological Sequelae

Patients may experience:

• Cognitive slowing and impaired concentration

• Memory disturbances

• Chronic headaches

• Sensory abnormalities or neuropathic pain

• Balance or coordination difficulties

• Mood or behavioral changes

• Mental fatigue and sleep disturbances
  
  

These symptoms can significantly affect daily functioning and long-term outcomes.

Electrical injury cases require specialized neurological evaluation. When objective findings are subtle, accurate interpretation depends on clinical correlation, symptom progression, and established neurobiological mechanisms—not imaging alone.

Understanding functional neurological injury is essential for informed clinical and legal assessment.
