The main objective is to demonstrate the effects of early dopaminergic activation on the autonomic nervous system in subjects with newly diagnosed vs. established type 2 diabetes. The primary endpoint is the effect of Bromocriptine QR on changes in autonomic function measured by assessing sympathetic and parasympathetic function using conventional measures of autonomic function, including power spectral analysis of heart rate as well as peripheral autonomic function using sudorimetry and laser scanning of peripheral microvascular autonomic control.
