Quantitative Schizophrenia Evaluation
A method has been developed that quantitatively evaluates neurological conditions, such as schizophrenia. Hypofunction of N-methyl-D-Aspartate (NMDA) receptors in the brain have been demonstrated to be correlated with the presence of schizophrenia. Moreover, dysfunction in the central nervous system should be mirrored in the retinal synaptic systems. Visually evoked responses have produced unique retinal signatures of NMDA receptor activation that can serve as a biomarker or classifier of schizophrenia. Specific metrics based on the unique signatures recorded using pattern electroretinography (pERG) have been demonstrated to classify patients into schizophrenia and control groups with high statistical significance.

Applications for Schizophrenia Biomarker
Schizophrenia affects approximately 1% of the global population. The capability to make early diagnosis before the disease manifests itself, provides the opportunity to head off non-reversible brain damage. Currently schizophrenia treatments are directed at treatment of symptom suppression after irreversible damage has occurred. With a new quantitative diagnostic tool and biomarker, early intervention and improved clinical outcome may be possible.
BENEFITS AND FEATURES OF QUANTITATIVE SCHIZOPHRENIA DIAGNOSTIC:
- Quantitative diagnostic of schizophrenia presence
- Potential to identify dysfunction prior to the occurrence of symptoms and irreversible brain damage
- Leverages capabilities of electroretinography (ERG) services, which are used clinically
Phase of Development Human studies of 23 schizophrenia subjects and 23 health controls with a p-value of 0.01
