Ultrasound Brain Tissue Pulsatility is decreased in middle aged and elderly type 2 diabetic patients with depression.

Abstract We used Tissue Pulsatility Imaging (TPI) to compare the Brain Tissue Pulsatility (BTP) in depressed ( n  = 11) and non-depressed ( n  = 13) type-2 diabetic non-demented patients aged 50 years and older. Both maximum and mean BTP were significantly decreased in depressed diabetic subjects compared to non-depressed diabetic subjects.
