Short answer

Tick paralysis is a rare neurological condition caused by toxins in the saliva of certain feeding female ticks, producing progressive weakness that can move upward through the body.

At a glance

It is not an infection, and recognising and removing the responsible tick is central to management, but respiratory support may be needed.

Key takeaways

• Progressive weakness is urgent.

• Search the entire scalp and body.

• People and animals need professional care.

The attached tick may be hidden

Small ticks can be concealed in hair, behind an ear or in skin folds. Weakness can resemble other neurological emergencies, so diagnosis must not be attempted at home.

Different regions involve different ticks

Australian paralysis ticks are particularly important for pets and can affect people. Clinical management and antiserum availability differ by country and species.
