This test is a simultaneous video and EEG recording of
the patient. This monitors and records the brain’s
activity and the physical manifestations of a seizure or
attack. Video EEG recording may be necessary for a few hours
to few days, depending on the indication.
The Jaslok Telemetry Unit: A special dedicated
monitoring room has been set up in the Neurology ICU located
on the 14th floor of the Jaslok Hospital. It is equipped
with a state of the art 128 channel digital EEG recording
machine linked to a digital infrared video camera. This
equipment is capable of recording non-stop for 72 hours
(three days). An EEG technologist, an ICU nurse and a doctor
are present round the clock in this unit. This ensures patient
safety and prompt therapy when seizures occur during telemetric
recordings.
The recording machine is located by the patient’s
bedside. However, the patient’s freedom to move around
in the room, watch television, and interact with family
members is unhampered. This unit is linked via a fast local
area network to a review station located in the Neurophysiology
department on the second floor.
Indications for prolonged
video EEG/telemetry:
-
Differentiating between seizures and
`pseudo-seizures’ – the latter do not arise
from the brain and usually have a psychological cause.
They can be a cause for the epilepsy becoming `poorly
controlled or intractable’. 
-
For classifying the
seizure type(s). This helps the Neurologist in selecting
the appropriate drug for the treatment of epilepsy.
-
Pre-surgical evaluation
of patients with poorly controlled epilepsy e.g. detecting
the epileptic focus in the brain prior to epilepsy surgery
such as temporal lobe epilepsy surgery or lesion removal.
-
Evaluating complex/unusual
paediatric epileptic syndromes, e.g. juvenile
absence epilepsy, eyelid myoclonia with absences, electrical
status in slow wave sleep.
