What if your doctor prescribed heart medication without checking your blood pressure and pulse, performing an EKG or a cardiac ultrasound or any other objective measure?

The brain is the most important organ in the body, yet we gather the least amount of information about it before making therapeutic recommendations or medicating it.

Digital Electroencephalogram Spectral Analysis and Evoked Potentials

The DESA  The DESA was developed at Harvard’s Boston Children's Hospital.  The DESA objectively evaluates 6 neuroelectrical functions in real time: EEG, VER, AER, FMAER, P300 & Coherence utilizing a 32 electrode cap.  Compares all functions to a 15,000 person database.  Results are interpreted by a neurologist.  Provides a visual S-D comparison (Spectral Analysis).

EEG (QEEG) A measurement of the background brainwaves including Alpha, Beta, Theta and Delta

EEG Abnormal Spike Activity Left Temporal Spike & Poly Spike

EEGEEG Abnormal Normal

Visual Evoked Response VER A measurement of the brain’s processing of visual stimuli

VER Yellen/Schweller Effect NORMAL Early hyperreactivity followed by delayed visual response

Auditory Evoked Response AER A measurement of the brain’s processing of auditory stimuli

AER NormalAbnormal

Frequency Modulated Auditory Evoked Response FMAER A measurement of the brain’s processing of language frequency stimuli

FMAERFMAER NormalAbnormal Absent FMAER on Second Trial

P300P300 A measurement of the brain’s processing of auditory working memory, e.g. the brain’s recognition of sound change

P300 Abnormal Normal

CoherenceCoherence The synchronicity of brain region functioning

CoherenceCoherence Normal Abnormal

Sleep Waves

Applications of the Data 1.Validate diagnostic hypotheses; 2.Identify undetected brain abnormalities; 3.Cross-validate learning disabilities including ADHD; 4.Cross-validate auditory and/or visual processing deficits; 5.Provide bases for intervention in psychotherapy, educational therapy and speech and language therapy; and 6.Provide bases for pharmacological interventions.

SummarySummary A good, comprehensive neuroelectrical study must include evaluations of the EEG, VER, AER, FMAER, P300 and Coherence functions of the brain.

ConclusionConclusion Information without comparison to normative database does not produce objective data with which to map out interventions.
