Diagnosis

• Primary care investigations
  Chest X–ray to rule out malignancy. Blood tests (eg. full blood count, erythrocyte sedimentation rate, electrolytes, renal function, liver function, calcium, and glucose) could show an underlying disorder or metabolic disturbance.
• Secondary care investigations
  Such as electroencephalography, neuroimaging, and metabolic screening in children, may aid seizure classification and help to determine the aetiology but they have limitations.
• Magnetic resonance imaging (MRI)
  Can better define the structures of the brain in three dimensions and can look at discrete areas of brain activation.
• Computed axial tomography (CAT)
  Has a role in the urgent assessment of seizures or when MRI is contraindicated, but it is less effective in detecting lesions.
• Electroencephalography (EEG)
  The EEG is not foolproof. It can only measure abnormal electrical activity that occurs during the test period and should not be performed to 'exclude' a diagnosis of epilepsy but should be used to support the classification of epileptic seizures and epilepsy syndromes when there is clinical doubt.
• Positron emission tomography (PET)
  Scanning is a highly specialized, expensive and largely unavailable technique that detects cerebral blood flow and metabolism.
• Single proton emission computerized tomography (SPECT)
  scanning is much cheaper and technically simpler than PET scanning it shows the areas where blood flows through your brain.
