Injuries After Seizures – Epilepsy: The Untold Side

Safety and recovery

Seizure-related injuries can range from minor bruises to fractures, burns, head injuries and shoulder dislocations. Some are obvious immediately. Others are missed because the person is confused, exhausted, amnesic or unable to describe pain clearly after the seizure.

Key point: postictal confusion can hide injury. If pain, swelling, weakness, vomiting, unusual drowsiness, reduced movement or another new symptom becomes apparent once the person is more awake, reassess rather than assuming it is just part of recovery.

Why injuries can happen during seizures

Injury may result from:

sudden loss of posture and a fall
forceful muscle contraction during a convulsive seizure
striking furniture, walls or flooring
contact with hot liquids, flames or appliances
falling down stairs or from height
seizures occurring in water
confused wandering or poor balance during recovery

The injury mechanism matters because a fracture or dislocation can occur even when there was no dramatic fall.

Postictal confusion can mask pain

Immediately after a seizure, a person may be confused, sleepy, agitated, unable to answer reliably or have little memory of what happened. They may not localise pain properly or may resist examination.

A useful approach is to reassess once the person is calmer and closer to their normal baseline. New pain, swelling, bruising, reduced movement or an unusual posture deserves attention even if it was not obvious immediately after the seizure.

Head injuries

Falls during seizures can cause scalp wounds, concussion, skull fracture or intracranial bleeding. Head injury assessment should follow standard head-injury guidance rather than assuming that confusion is entirely postictal.

Urgent assessment is especially important if there is:

persistent reduced consciousness
worsening confusion beyond the person’s usual recovery pattern
repeated vomiting
new weakness or another focal neurological deficit
suspected skull fracture
significant bleeding
a severe or worsening headache
a seizure that occurred after the head injury rather than causing it

NICE head-injury guidance uses specific criteria for urgent CT scanning, including reduced Glasgow Coma Scale, signs of skull fracture, focal neurological deficit, repeated vomiting and post-traumatic seizure.

The direction of events matters

There is an important distinction between:

a seizure that causes a fall and head injury
a head injury that is then followed by a post-traumatic seizure

These are clinically different scenarios and can affect emergency assessment and imaging decisions.

Shoulder dislocations are an important seizure injury

Powerful muscle contractions during tonic-clonic seizures can cause shoulder dislocation, sometimes without a major external impact.

Posterior shoulder dislocation is rare overall but is classically associated with seizures. A systematic review found seizures in about one-third of reported posterior shoulder-dislocation cases, and associated fractures or other structural injuries were common.

Warning signs include:

severe shoulder pain
inability to move the arm normally
the arm appearing fixed in an unusual position
swelling or deformity
pain that persists after the person becomes fully alert

Do not try to force a suspected dislocated shoulder back into place outside an appropriate clinical setting.

Fractures can occur from both falls and muscle contraction

Fractures may result from a fall, impact with furniture or the force of muscle contraction during a convulsive seizure. Shoulder fracture-dislocations are particularly well described, but wrist, arm, vertebral, hip and other fractures can also occur.

Consider fracture if there is persistent focal pain, swelling, deformity, inability to bear weight, reduced movement or pain on movement after the seizure.

Spinal injuries

Back or neck injury can occur during a fall or from forceful convulsive muscle contractions. Vertebral compression fractures have been reported after seizures.

New severe neck or back pain, limb weakness, numbness, altered sensation or loss of bladder or bowel control requires urgent assessment.

Cuts, bruises and soft-tissue injuries

Minor injuries are common: bruises, grazes, cuts, muscle strain and soft-tissue pain can occur from falls or contact with surrounding objects.

Clean minor wounds, control bleeding with direct pressure and monitor for infection. Larger wounds, deep cuts, uncontrolled bleeding or wounds involving the face, eye, hand or joint may need professional assessment.

Tongue and mouth injuries

Tongue biting, cheek biting, lip injuries and dental trauma can occur during seizures. Side-of-tongue biting is more associated with convulsive epileptic seizures than simple fainting, although it is not present in every seizure and is not diagnostic on its own.

Seek dental or medical review for:

deep tongue or mouth wounds
persistent bleeding
loose, broken or displaced teeth
difficulty swallowing
significant swelling

Burns and scalds

Seizure-related burns often occur in domestic settings, especially around hot drinks, cooking, heaters, baths and showers. Recent reviews continue to identify burns as an important preventable source of morbidity in epilepsy.

Older studies of burns-unit admissions found scalds to be particularly common and noted that some apparently small burns were deep and required surgery.

For a fresh thermal burn, cool the area with cool or lukewarm running water for 20 minutes as soon as possible, remove jewellery or clothing near the area if not stuck to the skin, and seek appropriate medical help for significant burns. Do not apply ice directly.

Water-related injury and aspiration

A seizure in water creates a drowning and aspiration risk. Even after apparently successful rescue, coughing, breathing difficulty, chest pain, low oxygen, unusual drowsiness or persistent respiratory symptoms require urgent medical assessment.

Aspiration can also occur when vomit or secretions enter the airway during or after a seizure, particularly when consciousness is impaired.

Breathing concerns after injury

Abnormal breathing after a seizure may be postictal, but it can also signal aspiration, chest injury, airway obstruction or another emergency.

Call 999 if breathing is severely abnormal, the person is blue or very pale, cannot maintain their airway, is not recovering as expected or has another major injury.

Incontinence is not an injury

Urinary or bowel incontinence can occur during seizures and should not be treated as evidence of trauma. However, wet floors can create a secondary slip risk for both the person and anyone helping them.

Preserve dignity, keep the area safe and assess separately for injury from any fall.

Delayed symptoms are important

Some injuries become obvious only after adrenaline, confusion and exhaustion have settled. Reassess later for:

new focal pain
swelling or bruising
reduced movement
difficulty walking
persistent headache
vomiting
new dizziness or neurological symptoms
pain when taking a deep breath

A person who cannot remember the seizure may not realise that they struck something hard or landed awkwardly.

When pain needs imaging

Imaging decisions depend on the injury, mechanism and examination. Persistent focal bone or joint pain, deformity, inability to bear weight, marked reduction in movement or neurological symptoms may justify X-ray, CT or other imaging.

In suspected shoulder dislocation, imaging is often needed because fractures and associated structural injuries are common.

Do not dismiss pain as “just muscle ache”

Generalised muscle soreness is common after tonic-clonic seizures, but localised severe pain, asymmetry, swelling or inability to use a limb normally should not be written off as routine postictal muscle pain.

Anticoagulants and bleeding risk

People taking anticoagulants or antiplatelet medicines may have a lower threshold for medical assessment after head injury because of increased bleeding risk. Current head-injury guidance includes medication-related risk factors in imaging decisions.

Bone health can change the injury risk

People with osteoporosis, older adults and those using some antiseizure medicines long term may have greater fracture risk. Recurrent falls and reduced bone density can compound each other.

What a witness should record after an injury

Useful information includes:

where and how the person fell
what they struck
whether the head hit the ground
which side of the body took the impact
whether there was bleeding
whether a limb looked abnormal immediately
when pain or swelling first became apparent
whether the person returned to their normal baseline

This can be especially useful when the person has no memory of the event.

When to call 999 after a seizure-related injury

Call emergency services when there is:

severe head injury or deteriorating consciousness
major bleeding
suspected spinal injury
obvious major fracture or dislocation with severe pain
severe breathing difficulty
significant burn
drowning or aspiration concern
a seizure emergency at the same time

Prevention should be proportionate

The goal is not to remove every activity from a person’s life. Practical risk reduction can include safer cooking methods, shower rather than bath where appropriate, reducing sharp furniture edges, avoiding unprotected heights, reviewing falls risk and improving seizure control.

The central point

Injury assessment does not end when the seizure ends. A person may initially look as though they are simply postictal, only for a fracture, dislocation, head injury or burn to become obvious later.

Compare recovery with the person’s usual baseline, reassess once they are more alert, and take persistent focal pain or new neurological symptoms seriously.
