Frailty is a state of reduced physiological reserve that makes a person more vulnerable to falls, illness, medication effects and loss of independence. In older adults with epilepsy, frailty can influence both seizure care and the consequences of seizures.
Frailty is not simply age
Two people of the same age can have very different levels of strength, mobility, cognition and resilience.
Frailty describes vulnerability across multiple systems rather than the number of years a person has lived.
Epilepsy and frailty can reinforce each other
Seizures can contribute to falls, injury, hospitalisation, fear of activity and functional decline.
At the same time, frailty can increase vulnerability to medication adverse effects, delirium, prolonged recovery and complications after a seizure.
Falls deserve special attention
Falls may be caused by seizures, syncope, balance problems, neuropathy, hypotension, sedating medicines or several factors at once.
Assuming every fall is epileptic can lead to unnecessary treatment, while assuming every fall is mechanical can miss seizures.
Medication tolerability becomes central
Older frail adults may be more sensitive to dizziness, sedation, gait disturbance and cognitive adverse effects.
Renal and hepatic function, body composition and other medicines can change drug exposure even when the prescribed dose has not changed.
Frailty can alter recovery
An older adult may take longer to regain mobility, orientation or confidence after a seizure or hospital admission.
Postictal recovery can overlap with delirium, infection and medication effects, so a new or prolonged change from baseline deserves assessment.
Treatment goals may be broader than seizure freedom
Reducing falls, maintaining independence, preserving cognition and minimising hospitalisation may be as important to the person as reducing seizure count.
This is why geriatric and epilepsy care sometimes need to be planned together.
Frailty assessment can improve context
Formal or informal frailty assessment can help clinicians understand baseline function and vulnerability.
Evidence in epilepsy is still developing, but recent reviews argue that frailty should be considered more explicitly in older-adult epilepsy research and care.
