Abstract
- Tick paralysis is caused by a neurotoxin secreted by female tick. Characteristic initial manifestation is bilateral flaccid ascending paralysis similar to Guillain-Barr? syndrome. The predominant electrophysiological abnormality is a reduction in complex muscle action potentials. Here, we present a 62-year-old man who initially experienced a sudden biting pain on his scalp. Subsequently he developed bilateral lower extremity paralysis that ascended symmetrically involving the upper extremities. Within 2 weeks, the patient showed a full recovery without treatment.
