Headshaking Syndrome in Horses: Welfare and Management

Equine headshaking syndrome is a distressing neurological condition causing involuntary head movement and facial pain that severely impacts the welfare of affected horses and their ability to be ridden.

Key Facts

Headshaking affects approximately 1 in 100 horses and is most commonly trigeminal neuralgia-based
Signs include violent upward head flicks, nose rubbing, snorting, and apparent facial pain
Seasonal photic headshaking is triggered by bright light through activation of the trigeminal nerve
Many horses are retired or euthanised due to the severity of symptoms and management difficulty
Surgical and pharmaceutical options provide relief in some but not all cases

Welfare Considerations

Horses with headshaking syndrome experience chronic facial pain and discomfort that makes riding impossible in severe cases, and affects quality of life even at rest. The involuntary nature of the head flicking, combined with the distress responses horses show during episodes, indicates significant suffering. Many cases go undiagnosed or are misinterpreted as behavioural problems, leading to inappropriate training pressure on horses in pain. Welfare-centred management includes accurate diagnosis, avoidance of known triggers, appropriate analgesia, and realistic assessment of workload.

What You Can Do

Seek referral to an equine neurologist if your horse shows signs of trigeminal neuralgia-based headshaking
Use UV-blocking nose nets and dark visors during turnout and exercise in sunny conditions
Avoid riding in bright conditions if photic headshaking is confirmed, and allow rest periods in shade
Engage with the Equine Headshaking Trust for owner support and evidence-based management resources
