Summary
CSF inositol was reported to be reduced in depression and inositol has been reported to be effective in treatment of depression. We studied CSF inositol in 18 drug-free depressed patients and 36 normal controls; the depressed patients then participated in an open trial of 18 gm daily inositol treatment for 4 weeks. There was no difference in pre-treatment CSF inositol between depressed patients and controls. CSF inositol levels did not predict response on the Hamilton Depression Scale to 4 weeks of inositol treatment.
