There is currently no quantitative measure of sleep propensity
to assess how well the patients are sleep derived. Researchers
using the NeuroScope™ have recently observed large
increases in the level of cardiac vagal tone in sleep deprived patients
and have recommended it as a quantitative measure of sleep
propensity. The NeuroScope™ can therefore be used to
assess sleep propensity during clinical investigation of sleep
disorders. There are sudden and extreme changes in the level
of cardiac vagal tone in tonic clonic or generalised epileptic
seizures. Such autonomic changes are suspected to be the cause
of sudden deaths in epilepsy. The NeuroScope™ is being
used as a non-invasive brain stem probe to assess the vulnerability
of various epileptic patients to brain stem seizures. There
is currently no such probe in the market and doctors rely
on speculations.
