Observations on Glyoxylic Acid Reaction in Mental Disease. ∗

Conclusions

A positive result with glyoxylic acid test was obtained in 62.5% of schizophrenic patients, while only 8% of non-schizophrenics gave a positive test. Though non-specific the test affords a statistically significant distinction which cannot be explained by the non-experimental variables. Because of the chance that the test has a significant association with the disease, schizophrenia, further investigation seems warranted.
