Neurological complication and sequel
Seizures: seizures are a rare complication of anaphylaxis, but they occur when brain function is severely compromised. The disruption in neural conduction causes the muscle to act rapidly, uncontrollably, and incoherently.
Surviving anaphylaxis or shock may result in permanent or transient neurological impairments. This can manifest as blurred vision and tremors that can impair the coordination of delicate movements.
