Abstract
Neuropsychiatric symptoms in the acute thyrotoxic phase of Graves’ disease suggest involvement of brain processes. Short-echo-time proton MRS was used to measure the cerebral metabolite profile in newly diagnosed and untreated Graves’ disease. Sixteen patients with Graves’ disease and 18 age- and sex-matched healthy volunteers were studied. The patients had significantly reduced total choline and myo-inositol in the acute phase of Graves’ thyrotoxicosis compared with the healthy volunteers.
