At Caribbean Neurology Services, we provide Neurophysiology Services which aim to assist Neurologists and Physicians in making a diagnosis. These tests are performed across all ages.

Electroencephalogram (EEG)

This is a test where we look at the brain waves. It is useful in the following conditions:

How To Prepare For Your EEG Test:

NOTE: We encourage patients to stay awake, the entire night before the procedure and to not sleep prior to the test. At a very minimum, patients must be awake fully for at least 4 hours prior to the test.


Different Types Of EEGs:

In most instances, your Physician would prescribe a routine EEG. However a sleep deprived EEG gives more information than a routine EEG as tiredness may change the brain waves giving us more information and some patients have seizures (events) in sleep.

In some instances your referring Physician may opt to request a sleep deprived EEG as the first line investigation.

In routine EEG’s and sleep deprived EEG’s, the total recording time varies from 20-40mins. There’s a high probability that abnormal waveforms may be missed on these recordings. Additionally, the triggers for your events may not be reproducible at the institution where the test is being performed or you may not have slept long enough on the recording to pick up the data. This is where an overnight, home based, roughly 24 hour recording is useful. It increases the detection rate.

At the moment this service is only offered in patients aged 14 years and older for the ambulatory home EEG. We provide our ambulatory EEG’s in partnership with Nyota-Tano diagnostics:


EEG testing & monitoring


Nerve Conduction Studies/Electromyography

This is a useful test whenever evaluating the peripheral nervous system (PNS). The major components of the PNS are nerves and muscles. Many patients present with weakness with may be progressive, fluctuating or long term. After a clinical examination, the referring Physician may want added information on whether your problem is originating from the nerves or muscles and if so, which ones.

The test starts with a brief clinical review where we take a history and brief targeted examination to assess the limbs required for the study. After this, we then proceed to the Nerve Conduction Study (NCS). This is where electricity is pulsed through a stimulator device at points in your hands or legs and recorded via electrodes. In some instances, we may need to deliver multiple shocks/pulses known as Repetitive Nerve Stimulation (RNS).

The next part of the test is the Electromyogram (EMG). This consists of a needle electrode inserted into the muscle. You will be asked to initially relax the muscle while we record and then contract the muscle at varying strengths for further information. Most tests require multiple needle sticks across multiple muscles for accurate recordings.
