Epilepsy is a condition in which excessive electrical activity in one part of the brain manifests as a seizure.

Seizures are not only the kind where consciousness is lost and the person collapses — briefly blanking out and becoming unresponsive, or one side twitching on its own, are seizures too. The person does not remember them, so they are easily overlooked.

EEG identifies abnormal electrical activity while brain MRI looks for a structural cause capable of provoking seizures, together narrowing down the seizure type and site of onset.

As seizures recur, ordinary moments — driving, swimming, stairs — become hazardous, and using medication without knowing the seizure type can actually increase their frequency. If you have had even one seizure, start by finding out why.

About electroencephalography

Electroencephalography (EEG)

An EEG records the brain's minute electrical activity by attaching electrodes to the scalp and amplifying the signal, allowing changes in brain function over time and across states to be observed. It can be performed awake or asleep, and because it involves only attaching electrodes, it is painless and straightforward.
EEG is used to diagnose and differentiate epilepsy, and it may also be performed in diagnosing a range of brain disorders including stroke, brain tumor, encephalitis, and declining brain function.

How is the test performed?

1. Lie comfortably while electrodes are attached to the scalp.
2. The basic study performed while awake is done lying flat and at rest; if you become sleepy during it, letting yourself sleep actually helps the examination.
3. During the EEG you follow the examiner's instructions, such as "close your eyes" or "take a breath in."

The duration differs between the basic study and the sleep study, and Usually 30 minutes to 1 hour for the basic study is the time required.

We recommend this for

  • Those who have lost consciousness and collapsed
  • Those who have had a seizure with stiffening or shaking
  • Those with recurring episodes of briefly blanking out and becoming unresponsive
  • Those with involuntary twitching in a particular area
  • Those who have had episodes they cannot remember afterwards
  • Those on epilepsy medication who need regular assessment

Advanced Equipment

  • SIEMENS3T AI MRIWe add AI imaging (Deep Resolve) to a proven Siemens 3T MRI to examine neurological conditions faster and more clearly.
  • MRACerebrovascular and carotid MRAIt accurately evaluates the degree of atherosclerosis, stenosis, structural abnormality, and the presence of aneurysm in the vessels of the brain and neck.
  • Carotid USCarotid UltrasoundCarotid wall thickness and plaque are examined to assess stroke risk.
  • NCS / EMGNerve conduction studiesNerves in the arms, legs, and face are safely stimulated electrically and the responses recorded, establishing whether peripheral nerve damage is present and how severe it is.
  • EPEvoked potential testBy safely stimulating the visual and auditory pathways electrically, damage to the cranial nerves can be identified.
  • EEGAI digital EEGBeyond the conventional identification of epileptiform waveforms, quantitative EEG with the latest AI software aids in assessing brain function in headache, anxiety, and depression.
  • VNGVideo nystagmographyBy recording and analyzing involuntary eye movement on video, this test is useful for distinguishing dizziness disorders such as BPPV and Meniere's disease.
