Horse Headshaking Trigeminal Neuralgia Welfare

Headshaking syndrome causes severe facial pain in horses through trigeminal neuralgia, significantly affecting welfare and rideability.

Key Facts

Headshaking affects approximately 4% of horses in seasonal and perennial forms
Trigeminal nerve irritation from light, heat, pollen, and exercise triggers attacks
Horses flip their heads violently and may rub their faces on objects to relieve pain
Cyproheptadine and carbamazepine provide partial relief in some horses
Photoperiod management and nose nets can reduce trigger exposure in seasonal cases

Welfare Considerations

Headshaking causes severe episodic facial pain that is distressing and unpredictable. Affected horses cannot consent to work during painful episodes, and welfare requires either effective treatment or reduction in work demands during symptomatic periods.

What You Can Do

Seek specialist neurological assessment if your horse shows headshaking symptoms
Explore all management options including photoperiod and trigger reduction
Consider retirement from ridden work if headshaking cannot be adequately controlled
