Thyroid MIBG uptake in Parkinson's disease with diabetes mellitus

초록

In our work, we investigated thyroid and cardiac MIBG uptake as potential differential markers. We observed reduced cardiac uptake of MIBG in PD and diabetic CAN, in agreement with the previous studies. However, there was a significant difference between the PD and diabetic cardiac autonomic neuropathy groups with respect to early and delayed thyroid MIBG uptake, in that reduced thyroid MIBG uptake was seen in PD but not in diabetic autonomic neuropathy. We therefore propose that this parameter could be a marker for identifying parkinsonism when it presents together with DM.
