Note:—Concentrations are reported in institutional units (IU). N-acetylaspartate (NAA), creatine and phosphocreatine (Cr & PCr), choline (Cho), myo-inositol (mIns), glutamate/ glutamine (Glx) concentration values are reported from the spectroscopy acquired at an echo time of 35 ms from the left frontal white matter. Lactate concentration values are reported from the spectroscopy acquired at an echo time of 288 ms from the left frontal white matter. Acquisitions used a repetition time of 2000 ms.
