Epilepsy is a neurological condition characterised by a continuing tendency to experience unprovoked seizures. Diagnosis involves detailed symptom history, witness descriptions and selected investigations such as electroencephalography and brain imaging. Treatment commonly includes appropriate anti-seizure medication, education about seizure safety and regular follow-up to monitor control and adverse effects.
Focal seizures begin within a particular network in one part of the brain. Symptoms may include unusual movements, altered sensations, changes in awareness or temporary difficulty responding. Evaluation aims to identify seizure characteristics and potential underlying causes. Treatment is selected according to the seizure type and individual medical history.
Generalised seizures involve brain networks on both sides of the brain from their onset. Symptoms vary and may include loss of awareness, muscle stiffening, jerking movements or brief interruptions in activity. Diagnosis involves clinical history and appropriate testing. Treatment depends on the specific seizure syndrome and individual patient needs.
Absence seizures cause brief interruptions in awareness that may appear as staring episodes or sudden pauses in activity. They can sometimes be mistaken for inattention, particularly in children. Evaluation may include a detailed description of events and EEG testing. Treatment depends on the diagnosis and the specific epilepsy syndrome.
Tonic-clonic seizures may involve loss of consciousness, muscle stiffening and rhythmic jerking of the limbs. They can occur in different epilepsy syndromes and may create a risk of injury. Management focuses on identifying the cause, selecting appropriate medication, educating families about seizure first aid and monitoring recurrence.
Recurrent seizure-like episodes require careful assessment because similar symptoms may arise from epilepsy, fainting, sleep disorders or other conditions. Evaluation considers the timing, duration, triggers and nature of each episode. EEG and imaging may be recommended when appropriate to help establish the diagnosis and guide treatment.
Drug-resistant epilepsy is generally considered when seizures continue despite adequate trials of two appropriately selected and tolerated anti-seizure medication regimens. Specialist evaluation may review the original diagnosis, medication history and possible treatment alternatives. Selected patients may benefit from referral to a comprehensive epilepsy centre for further assessment.
Anti-seizure medications are used to reduce the likelihood of seizures in patients with epilepsy. Selection depends on seizure type, other medical conditions, possible interactions and patient-specific considerations. Follow-up includes reviewing seizure frequency, adverse effects and adherence. Patients should not change or discontinue prescribed medication without medical advice.
Electroencephalography records electrical activity from the brain using electrodes placed on the scalp. EEG may help classify seizures and provide information relevant to epilepsy diagnosis. Results must be interpreted alongside the patient's history because a normal EEG does not exclude epilepsy and abnormal findings require clinical correlation.
Video EEG monitoring combines prolonged recording of brain electrical activity with video observation. It may help clinicians distinguish epileptic seizures from other episodes and classify seizure types. The need for monitoring and its duration depend on clinical circumstances. Availability at the selected hospital must be confirmed.
A first suspected seizure requires medical assessment to determine whether the event was epileptic and identify possible triggers or underlying causes. Investigations may include blood tests, brain imaging and EEG, depending on the circumstances. Treatment decisions consider recurrence risk, investigation findings and the individual's overall health.
Brain imaging, particularly MRI, may be recommended during epilepsy evaluation to identify structural abnormalities that could contribute to seizures. Imaging findings are reviewed alongside the neurological examination and seizure history. Not every patient requires the same imaging approach, and treatment decisions depend on the overall clinical assessment.
Seizure safety counselling helps patients and families reduce injury risks and understand appropriate first aid. Discussions may include medication adherence, sleep, known seizure triggers and safety around swimming, heights or driving. Advice should be tailored to seizure control, individual circumstances and applicable local regulations.
General neurology consultation evaluates symptoms related to the brain, spinal cord and peripheral nervous system. Patients may present with headaches, weakness, altered sensation, abnormal movements or changes in awareness. Assessment begins with a detailed medical history and neurological examination, followed by targeted investigations when clinically indicated.
