Background: Peripheral arterial disease (PAD) was reported to increase the risk of dementia(s) even more than stroke. We assessed prevalence PAD in a group with definite diagnosis dementia. Methods: Patients aged 65 years or older Alzheimer’s (AD), vascular dementia (VaD), AD-VaD were enrolled (n = 162, mean age: 78.87 [6.05] years). An age- and gender-matched control also included 190). diagnosed by ankle–brachial index. Results: Frequency among patients without 35.2% 16.3%, respectively (...

The main aim of this study is to evaluate the role blink reflex for early diagnosis cranial neuropathy in diabetic patients with or without polneuropathy. Ninety-five were included present evaluation reflex. divided into two groups according having not. Both R1, R2i and R2c latencies all polyneuropathy prolonged relative controls differences statistically significant (p < .001). R1 These findings presumably reflect that facial nerve severly involved polyneuropathy. Finally value detection...

Polycystic ovary syndrome (PCOS) was linked to increased lifetime risk of cardiovascular disease. A low ankle–brachial index (ABI) is associated with accelerated atherosclerosis. The ABI value and the conditions in women PCOS were searched present study. measured using a handheld Doppler device calculated both standard modified definitions. Women (n = 103, mean age 24.9 ± 5.9 years) had 1.10 0.10. (≤0.9) 2.9% 14.6% definitions, respectively. Mean correlated negatively body weight, BMI, waist...

Cushing's syndrome increases the risk of cardiovascular disease. The triglyceride-glucose (TyG) index has been linked to an increased cardiometabolic disorders. Whether patients with non-functioning adrenal incidentaloma (NFAI) or cortisol-secreting (CSAI) have altered TyG is unknown. Therefore, we aimed investigate between and controls.
