摘要
Brain phosphorus metabolism was measured by P-31-MRS in 15 patients with bipolar II disorder (BP II) and 14 patients with bipolar I disorder (BP I). Phosphocreatine (PCr)levels were significantly lower in patients with BP II in all three psychiatric states compared to 59 normal controls (PCr (%) was 13.5 +/- 1.5 (mean +/- SD) for controls, and 12.2 +/- 1.7, 12.1 +/- 1.3, 12.0 +/- 1.9 for hypomanic, euthymic and depressed bipolar II patients respectively). High values of phosphomonoester (PME) were found in BP II patients in the hypomanic and depressive states, but PME values in the euthymic state did not differ significantly from controls. Intracellular pH of BP II patients in all three psychiatric phases was similar to control values, whereas euthymic BP I patients had lower pH values. These results suggest that brain high energy phosphate metabolism may be impaired in BP II and that there may be pathophysiological differences between BP I and BP II.
