Electroencephalography (EEG)

• Routine digital EEG recordings on patients over 5 years of age
• Sleep deprived EEGs can also be recorded

Reasons for referral can include:

1. To detect epileptiform or epileptic activity in patients with or suspected to have epilepsy.

    Can be helpful in classifying a patients epilepsy syndrome.

2. To detect evidence of cerebral dysfunction in a wide range of clinical scenarios such as viral   

    encephalitis, spongiform encephalopathy, metabolic encephalopathy and dementia.

Nerve Conduction and Needle EMG studies

Studies are carried out by clinicians qualified in the field of Neurography and Electromyography. Most investigations last approximately 30 minutes. Complicated cases may take longer.

Reasons for referral can include detection of:

• Peripheral Neuropathies: Can be considered as either generalized or local. Generalised includes sensory-motor peripheral neuropathy and anterior horn cell disorders. Focal/multifocal includes entrapment neuropathies such as carpel tunnel syndrome, radiculopathy, mononeuropathies and mononeuropathy multiplex.

• Myopathic disorders e.g. inflammatory myopathies and muscular dystrophies.

• Disorders of Neuromuscular transmission e.g. Myasthenia Gravis and Lambert-Eaton Myasthenic Syndrome.
