Seizures: seizures are a rare outcome of anaphylaxis, but result when the brain function is severely impaired. The disturbance in neurological conduction causes the muscle to act in a rapid, uncontrollable, uncoordinated fashion.
Sequels: survivors of anaphylaxis or shock may have permanent or temporary neurological deficits. This can manifest as blurred vision, and tremors which may affect fine, coordinated movements.
