QEEG Guided Treatment of Coma/Minimal Consciousness
Serial QEEG studies and source localization (see above) have been
used to evaluate cognitive processing in patients who are persistent
vegetative state (PVS). QEEG abnormalities observed in these
patients are considered to reflect imbalances in brain
neurotransmitter availability. With the assumption that the brains
of patients in PVS have been down-regulated as an inherent
protective mechanism, decreasing responsiveness to external
stimulation which further adds to the down-regulation, medications
have been administered by the medical clinical team to block
inhibitory neurotransmitters. After optimal blockade of inhibition
has been achieved, as reflected in the QEEG features moving toward
normal, further improvement is sought by administration of
excitatory neurotransmitters. Patients are then placed on a
individualized optimal medication regimen to balance excitatory and
inhibitory influences. QEEG trajectories are constructed by regular
serial evaluations of brain function and cognitive status probed by
use of neurocognitive challenges. A number of patients considered
hopeless in their conventional hospital stay, have been transferred
to care under such a protocol in both acute and sub-acute settings,
have been restored to a minimally conscious state (MCS) or better.
