Epilepsy is the most common neurological disorder, affecting about 4% of Australians (Epilepsy Foundation 2019a).
What is Epilepsy?
Epilepsy is a chronic neurological condition that causes an individual to experience recurrent seizures (WHO 2019; Epilepsy Action Australia 2020).
It is important to note that the term epilepsy refers to a range of disorders that can cause seizures; it is not a singular condition. For this reason, people with epilepsy have varying experiences (Healthdirect 2019a; Epilepsy Action Australia 2020).
While epilepsy can affect anyone, people are more likely to be diagnosed in childhood or older age (Epilepsy Action Australia 2020).
Epilepsy may eventually stop with age or be a life-long condition, but seizures can often be controlled using medication (Epilepsy Action Australia 2020).
Epilepsy v Seizure
These two terms are related but not interchangeable.
A seizure is a sudden neurological event in which the electrical impulses in the brain are disrupted by an uncontrolled surge of electrical activity (Epilepsy Action Australia 2020; Better Health Channel 2019a).
This may result in symptoms such as:
Loss of consciousness;
Loss of awareness or blank staring;
Convulsions and involuntary movements;
Confusion or disorientation;
(Epilepsy Action Australia 2020; Epilepsy Foundation 2019a; Healthdirect 2019b)
Seizures vary in severity and usually last for up to two to three minutes (Epilepsy Action Australia 2020).
While epilepsy causes an individual to experience seizures, having a seizure does not necessarily mean an individual has epilepsy. Epilepsy is generally diagnosed if someone has had at least two unprovoked seizures, but about half of the people who have one seizure will never experience another one (Healthdirect 2019a; WHO 2020).
Causes of Epilepsy
Only about half of people with epilepsy are able to have the cause of their condition identified (Epilepsy Action Australia 2020). Potential causes include:
Head injury (e.g. due to trauma, an accident or a fall);
Stroke or brain hemorrhage;
Lack of oxygen to the brain for a long period of time (e.g. birth trauma, cardiac arrest, drowning, drug overdose);
Brain infection (e.g. meningitis, encephalitis or brain abscess);
Brain abnormalities at birth;
Degenerative conditions that affect the brain (e.g. dementia); and
Heavy alcohol or drug use.
(Epilepsy Action Australia 2020; Healthdirect 2019a)
The following factors (depending on the individual) may trigger people with epilepsy to have a seizure:
Low blood glucose;
Emotional and physical stress;
Missing or changing medicines;
Certain recreational and prescription drugs;
Flickering lights or patterns;
Illness, especially if the individual is experiencing diarrhoea or vomiting; and
Significant changes to body temperature.
(Better Health Channel 2019a; Epilepsy Foundation 2019a)
The Impact of Epilepsy on the Individual
Epilepsy may significantly affect an individual’s quality of life (Vaurio, Karantzoulis & Barr 2016).
People who are newly diagnosed with epilepsy may have difficulty adjusting, particularly if they need to take new medicines or make changes to their lifestyle (Epilepsy Action Australia 2019).
Mental illness is prevalent among people with epilepsy, with about 50% experiencing depression (two to three times more than the general population) and 20% experiencing anxiety (Beyond Blue 2010).
While about 70% of people with epilepsy are able to control their seizures with medication, those who still experience seizures or have untreated or poorly-controlled epilepsy are at risk of injury, falls and even death, especially if seizures occur without notice (Better Health Channel 2019b).
People with epilepsy are also up to three times more likely to suffer premature mortality (WHO 2020).
Epilepsy may have a variety of other impacts, including:
Loss of functional capacity and independence (e.g. not being able to drive);
Practical Tips for Caring for Clients With Epilepsy
The following are some tips for caring for clients who have epilepsy, especially in aged care settings:
If the client is taking AEDs, these may interact with other medicines and treatments. Always assess the potential for interaction before administering a medicine or treatment.
If a client who takes AEDs is required to fast for a particular procedure, the first step is to liaise with medical staff and ensure they are aware that the client requires AEDs. You should discuss whether it is appropriate to withhold the AEDs during the fasting period.
If a client is experiencing seizures, document the duration of symptoms, the frequency of the seizures and the ways in which the seizures are affecting the client. Consider filming the seizure as a video record (only with the client’s consent). Consider having a discussion upon the client's admission or at an appropriate time to establish consent for filming if a seizure was to occur.
Ensure clients are getting adequate sleep, nutrition, exercise and stimulation.
Consider devices and assistive technologies (e.g. medical bracelets, ID cards, fall detector pendants) that will help ensure the client’s safety.
Bathe clients in the shower rather than the bath, as this is safer. Use a shower chair if possible.
Consider softer floor surfaces such as soft wool carpeting or cushioned linoleum, as these are safer in the event of a fall.
Remove clutter and tripping hazards.
Provide clients with firm pillows rather than soft pillows, as these are less likely to cause suffocation in the event of a seizure.
Ensure you are appropriately trained in seizure first aid and know how to keep the client safe during a seizure.
Support any required interventions (e.g. psychotherapy, support groups) and refer the client if necessary.

While epilepsy can often be managed, seizures have the potential to result in serious harm. Therefore, understanding this condition and knowing how to keep a client safe in the event of a seizure is essential.
