ElectroEncephaloGram

ElectroEncephaloGram (EEG) is a harmless and painless investigation of the tiny natural electrical patterns from the brain that may be changed by certain disorders. The signals are monitored after we place 24 pads on the head and connecting them to a computer, the results then being saved onto disc. The recording is made by a clinical physiologist and later interpreted by a consultant neurophysiologist who specialises in reading EEGs.

Definition of physiological measurement (EEG)

The recording of those electrophysiological parameters appertaining to neurological function with a view to either aid diagnosis, monitor progress, or screen for a wide range of medical and psychiatric conditions.

The whole investigation usually lasts about 30 minutes during which time the patient will be asked to remain still and relaxed with the eyes closed, also possibly to take deep breaths for a short time and/or look at a flickering light. The trace is then analysed and we send a report to the referring doctor within a few days. There are no after-effects and the patient is free to return to their home or ward straight away.

The test

The test is performed on people of all ages to assess brain function. This means that a whole range of conditions fall within our scope and includes:

• Epilepsy
• Migraine
• Dementia
• Cerebrovascular accident (stroke)
• Cerebrovascular disease
• Head injuries
• Blackouts
• Headaches
• Brain infection
• Neurological disorders
• Encephalopathies

This list is not exhaustive - much EEG work is undertaken to exclude clinical possibilities rather than find them.

Mission statement

We aim to work as a team to provide a high quality service, to ensure that the client receives maximum care and attention by the efficient use of resources, and in order to optimise the information available to aid diagnosis.

Our services

We are open Monday to Friday from 8.45am until 5.30pm. An answer phone is available out of hours. Appointments are usually offered within two weeks of referral by the doctor. Reports are sent out within 24 hours of the record being read by the consultant. We also offer private patient recordings and direct access for GPs.

Specialist services

• Extra departmental (portable) recordings.
• Sleep deprived recordings.
• Sleep recordings (natural and drug-induced).
• Videometry
• Paediatric recordings

Our core standards for our patients

• Patients wherever possible shall be informed about procedures and treated with respect and dignity.
• All patients will receive prompt attention upon arrival at the department; the ultimate aim is to see all our patients on time.
• Information packages are sent to each patient with their appointment.
• The appointment system is flexible within the defined hours.
• Appointments are available as follows:
  Outpatients: Two weeks
  Inpatients: 48 hours
  Emergencies: 24 hours
• Reports are dispatched within 24 hours of the record being read by the consultant neurophysiologist.
• When the consultant neurophysiologist’s report is unavailable interim technical reports may be provided upon request. 
• No patient will have cause to return for a repeat recording due to technical incompetence.
• All staff working within the department hold professional qualifications and work to high standards.
• The safety of patients, visitors and staff is paramount.
• All procedures or methods of working are adhered to as defined by existing trust policies and professional guidelines.

Our staff

• EEG service manager or chief clinical physiologist (Neurophysiology).
• Senior clinical physiologist (neurophysiology).
• Consultant neurophysiologist (adult EEG).
• Consultant paediatric neurologist (children).
