Tick paralysis
Tick Paralysis
Tick paralysis is a condition caused by the bite of a female tick, typically of the species Ixodes holocyclus or Dermacentor andersoni. It is characterized by an acute, ascending, flaccid motor paralysis that can lead to respiratory failure if not promptly treated.
Pronunciation
Tick paralysis: /tɪk pɑːrəlaɪsɪs/
Etymology
The term "tick paralysis" is derived from the Old English ticcen meaning "tick" and the Greek parálysis meaning "disablement of the side".
Symptoms
The symptoms of tick paralysis may include fatigue, numbness of the lower extremities, muscle pains, and paralysis that ascends to the upper body. In severe cases, it can lead to respiratory failure and death.
Causes
Tick paralysis is caused by a neurotoxin produced in the tick's salivary gland. During a blood meal, the tick transmits the toxin to its host.
Diagnosis
Diagnosis is typically based on the presence of a tick, the characteristic progression of symptoms, and the rapid recovery following tick removal.
Treatment
The primary treatment for tick paralysis is the removal of the tick. In severe cases, supportive care such as respiratory support may be required.
Prevention
Prevention strategies include avoiding tick-infested areas, using tick repellents, and performing regular tick checks.
