There is an increase in cardiovascular risk factors in polycystic ovarian syndrome (PCOS) compared with BMI matched controls. Almost all women with PCOS are insulin resistant and increased cardiovascular risk is commonly attributed to insulin resistance (IR). However, it is unclear if cardiovascular risk differs in women with PCOS compared to equally insulin resistant women. We performed a case–control study (n=56 pairs) of women with PCOS (NIH criteria) compared t...

Women with polycystic ovary syndrome (PCOS) have an increased prevalence of cardiovascular risk factors. Insulin resistance (IR) is believed to be an important factor in the pathogenesis of both PCOS and cardiovascular disease and thus provides a plausible link between these two conditions. An exaggerated post-prandial triglyceride (TG) response is thought to be one of the mechanisms through which IR is associated with atherosclerosis. The aim of this study was to compare fast...

The neuropsychological mechanism underlying cognitive impairment in hypothyroidism is poorly understood. It is not known whether cognitive impairment resolves following L-Thyroxine (LT4) replacement. It is also unknown whether similar neuropsychological abnormalities occur in patients with sub-clinical hypothyroidism (SCH). To address these questions, we performed neuropsychological tests in 17 patients with hypothyroidism (age 45±3 years; mean±S.E.M.)...

Memory formation largely depends on normal function of the temporal lobes (particularly the hippocampal complex) and prefrontal cortex. Evidence from animal studies suggests abnormal hippocampal function in hypothyroidism1. We hypothesized that specific defects in hippocampal-dependent memory would be observed in hypothyroid patients. Patients with overt (n=17) and subclinical (n=17) hypothyroidism underwent neuropsychological testing at baseline, 3 an...
