While some autoimmune disorders remain extremely rare, others largely predominate the epidemiology of human autoimmunity. Notably, these include psoriasis, diabetes, vitiligo, thyroiditis, rheumatoid arthritis and multiple sclerosis. Thus, despite the quasi-infinite number of "self" antigens that could theoretically trigger autoimmune responses, only a limited set of antigens, referred here as superautoantigens, induce pathogenic adaptive responses. Several lines of evidence reviewed in this paper indicate that, irrespective of the targeted organ (e...

Diabetes mellitus is associated with an elevated risk of cognitive impairment and dementia. Cerebrovascular disease and neurodegeneration are two major pathways that may explain the effect of diabetes on the brain and therefore deserve investigation. Neuroimaging provides an effective way to investigate the contribution of these pathways in vivo, guiding further mechanistic research and providing biomarkers for clinical correlation or interventional studies. In this paper, we present a narrative review of the state of play with neuroimaging evidence in studies of people with diabetes mellitus, how these data are useful in understanding mechanistic links between diabetes and brain impairment, and possible ways that the field may develop in the future...

Diabetic encephalopathy, a proven complication of diabetes is associated with gradually developing end-organ damage in the CNS increasing the risk of stroke, cognitive dysfunction or Alzheimer's disease. This study investigated the response of rat cortical mitochondria to streptozotocin-induced diabetes and the potential for fish oil emulsion (FOE) to modulate mitochondrial function. Diabetes-induced deregulation of the respiratory chain function as a result of diminished complex I activity (CI) and cytochrome c oxidase hyperactivity was associated with attenuation of antioxidant defense of isolated cortical mitochondria, monitored by SOD activity, the thiol content, the dityrosine and protein-lipid peroxidation adduct formation...

Identifying genes regulating the pace of epigenetic ageing represents a new frontier in genome-wide association studies (GWASs). Here using 1,796 brain samples from 1,163 individuals, we carry out a GWAS of two DNA methylation-based biomarkers of brain age: the epigenetic ageing rate and estimated proportion of neurons. Locus 17q11.2 is significantly associated (P=4.5 × 10(-9)) with the ageing rate across five brain regions and harbours a cis-expression quantitative trait locus for EFCAB5 (P=3.4 × 10(-20))...

The relationship between medical diseases and cognition has been a point of interest in the last decades. In recent years studies in this field have developed significantly applying various tools such as cognitive tests using psychometric assessments and brain imaging techniques. The main focus of cognitive function in this studies is the process through which this cognition is obtained. It seems a novel methodology is needed while assessing the impact of diseases such as diabetes on cognition based on heavenly religious teachings in which cognition is believed to be the main source of human bliss and not just some measurable quantitative components...

Defects in hippocampal synaptic plasticity and disorders of memory and learning are the central nervous system complications of diabetes mellitus (DM). Here, we used a streptozotocin-induced rat DM model to investigate the effects of long non-coding RNA H19 (lncRNA H19) on learning and memory and apoptosis of hippocampal neurons, and the involvement of the Wnt signaling. Our data demonstrate that lncRNA H19 is highly expressed in rats with DM. Over-expression of lncRNA H19 increased positioning navigation latency in DM rats and decreased duration of space exploration...

AIMS: Centrally administered insulin improves cognitive functions in patients with Alzheimer's disease; however, it remains unknown whether long-acting insulin analogs exert more pronounced effects than insulin. In the present study, we directly compared the effects of insulin and its analogs on neural functions in vitro and in vivo. METHODS: Cultured rat cerebral cortical neurons were treated with insulin, insulin glargine U100 (Gla), insulin detemir (Det), or insulin degludec (Deg)...

Background: Previous studies have shown that individuals with diabetes exhibit accelerated cognitive decline. However, methodological limitations have limited the quality of this evidence. Heterogeneity in study design, cognitive test administration, and methods of analysis of cognitive data have made it difficult to synthesize and translate findings to practice. We analyzed longitudinal data from the Ginkgo Evaluation of Memory Study to test our hypothesis that older adults with diabetes have greater test-specific and domain-specific cognitive declines compared to older adults without diabetes...

OBJECTIVES: Hypertension, dyslipidemia, diabetes, and obesity are well-established risk factors for cognitive impairment and dementia in older adults. In contrast, previous studies that have assessed the impact of vascular risk factors (VRFs) on cognition in Parkinson's disease (PD) have had methodological limitations and reported conflicting findings. We address this question in a large well-characterized cohort of de novo PD patients. METHODS: A total of 367 untreated and non-demented patients aged 50 years and older with early PD (H&Y = 1...

BACKGROUND: Depression is twice as common in diabetes mellitus (DM) as the general population and is associated with adverse health outcomes, but access to evidence-based therapies such as cognitive behavioral therapy (CBT) is limited in routine diabetes care. Past research has shown that generic Internet-based cognitive behavioral therapy (iCBT) is an effective treatment for depression in the general population, but it has never been evaluated in people with comorbid depression and DM...

The high prevalence of obesity is associated with an enormous medical, social, and economic burden. The metabolic dysfunction, dyslipidaemia, and inflammation caused by obesity contribute to the development of a wide variety of disorders and effects on the nervous system. In the CNS, mild cognitive impairment can be attributed to obesity-induced alterations in hippocampal structure and function in some patients. Likewise, compromised hypothalamic function and subsequent defects in maintaining whole-body energy balance might be early events that contribute to weight gain and obesity development...

INTRODUCTION: Preclinical studies demonstrate the potential of amylin in the diagnosis of Alzheimer's disease (AD). We aimed to lay the foundation for repurposing the amylin analog and a diabetes drug, pramlintide, for AD in humans. METHODS: We administered a single subcutaneous injection of 60 μg of pramlintide to nondiabetic subjects under fasting conditions. RESULTS: None of the participants developed hypoglycemia after the injection of pramlintide...

Type 2 diabetes (T2D) has been associated with cognitive decline, dementia and Alzheimer's disease (AD). Remarkably, the pathophysiological mechanisms behind this are still mostly unknown. Cognition and memory formation are associated with gamma oscillations in hippocampal neuronal networks and fast-spiking, parvalbumin-expressing interneurons (PV+ IN) play a key role in these processes.

OBJECTIVE: Hemoglobin A1c (HbA1c), a measure of average blood glucose level, is associated with the risk of dementia and cognitive impairment. However, the role of glycemic variability or glucose excursions in this association is unclear. We examined the association of glucose peaks in midlife, as determined by the measurement of 1,5-anhydroglucitol (1,5-AG) level, with the risk of dementia and 20-year cognitive decline. RESEARCH DESIGN AND METHODS: Nearly 13,000 participants from the Atherosclerosis Risk in Communities (ARIC) study were examined...

OBJECTIVE: We examined the association of the Diabetes Prevention Program (DPP) intervention arms (lifestyle intervention, metformin, and placebo) with cognition in the DPP Outcomes Study (DPPOS). We also examined metformin use, incident type 2 diabetes, and glycemia as exposures. RESEARCH DESIGN AND METHODS: The DPP lasted 2.8 years, followed by a 13-month bridge to DPPOS. Cognition was assessed in DPPOS years 8 and 10 (12 and 14 years after randomization) with the Spanish English Verbal Learning Test (SEVLT), letter fluency and animal fluency tests, Digit Symbol Substitution Test (DSST), and a composite cognitive score...

Diabetes comes with an additional burden of moderate to severe hyperlipidemia, but little is known about the effects of lipid-lowering therapy on diabetic complications such as diabetes-associated cognitive decline. Herein we investigated the effects of statins on memory impairment and neurotoxicity in streptozotocin-induced diabetic mice. Our data indicated that oral administration of simvastatin at 10 or 20mg/kg for 4weeks significantly ameliorated diabetes-associated memory impairment reflected by performance better in the Morris water maze and Y-maze tests...

BACKGROUND: In the "fourth stage" of epidemiological transition, the distribution of non-communicable diseases is expected to shift to more advanced ages, but age-specific changes beyond 80 years of age have not been reported. METHODS: This study aimed to evaluate demographic and health transitions in a population aged 80 years and over in the United Kingdom from 1990 to 2014, using primary care electronic health records. Epidemiological analysis of chronic morbidities and age-related impairments included a cohort of 299,495 participants, with stratified sampling by five-year age group up to 100 years and over...
