Services

Doppler

Outpatient Doppler services are provided for investigation of cerebrovascular disturbances, including stroke, with the use of a non-invasive procedure.

Electroencephalography (EEG)

Electroencephalography records the electrical activity of the brain. Its is useful for the investigation and management of choice for patients suspected of suffering from epilepsy and other neurological dysfunction.

First Seizure Clinic:

A specialized service is provided for patients who have recently had their first ever seizure. The EEG test is most helpful if performed within 24 hours of the seizure, although there is still value, if this is not feasible, in performing it later. Appointment information is given to each patient about the ‘First Seizure Clinic' at the Heidelberg Repatriation Hospital where the patient is seen by a Neurologist/Epileptologist. If you wish to refer for a "first seizure" EEG from another hospital, the Austin Epilepsy registrar must first be contacted through switchboard on 03 9496 5000 to discuss the timing of the EEG and attendance at the ‘First Seizure Clinic'".

 

Routine Electroencephalography:

A routine EEG takes approximately 45 minutes to perform. Electrodes will be applied on your head to record EEG. Video will also be recorded to monitor any clinical seizure. You will be asked to close your eyes almost throughout the test. The EEG scientist will also ask you to do some deep breathing for three minutes and to watch a flashing light. You will be required to be relaxed and still for the test.

For further information, please refer to patient information.

 

Sleep deprived EEG:

Patient may be referred for sleep deprivation test if the initial EEG is negative, an EEG performed after a night of sleep deprivation may increase the ‘pick up' rate to support a diagnosis of epilepsy.

 

Day monitoring EEG:

This new service is to diagnose or quantify events that occur at least a few times per day. It may be useful to diagnose brief staring spells where epilepsy is suspected or to help determine if someone with known absences may be safe to drive.

 

Long term EEG monitoring:

Long term EEG monitoring is an inpatient EEG service designed to cater for 2 situations:

  • The patient suspected of having epilepsy with frequent events where the routine or sleep deprived EEG tests have been normal. A period of video-EEG monitoring over several days is performed in the hope of capturing an event to determine whether the cause is epilepsy or not.
  • The patient with continued seizures despite anticonvulsant treatment. A prolonged period of video-EEG monitoring over several days is performed in the hope of capturing seizures. This is used to determine whether the cause is focal or generalised epilepsy and whether or not the patient may be a candidate for epilepsy surgery to remove the seizure focus.

Patients who undergo this test require a consultation with an Austin Neurology consultant to be referred for Long term EEG monitoring.

 

Electromyography & Nerve Conduction studies (EMG/NCS)

EMG /NCS are performed to check overall integrity of nerves and muscles. This test remains the best initial test for the diagnosis of peripheral nerve and muscle disorders.

Common entities diagnosed using this test include nerve entrapments (carpal tunnel syndrome, ulnar nerve lesion at the elbow), nerve root compression due to herniated lumbar or cervical disc, peripheral neuropathy and muscle disorders such as muscular dystrophy, polymyositis and vasculitis amongst others.

Neuro-otology

Neuro-otological investigations are primarily designed for the diagnosis of the ‘dizzy patient'. Various central and peripheral causes of vertigo can be diagnosed with the aid of these investigations, leading to selection of appropriate treatment.

Evoked potential

Evoked potential studies are designed to aid in the diagnosis of problems involving the central nervous system affecting sensation, vision or hearing.
