The World Alzheimer Report 2016 estimated that 47 million people are living with dementia worldwide (Alzheimer's Disease International, 2016). In the inaugural World Health Organization Ministerial Conference on Global Action against Dementia, six of the top ten research priorities were focused on prevention, identification, and reduction of dementia risk, and on delivery and quality of care for people with dementia and their carers (Shah et al., 2016). While the Lancet Neurology Commission has suggested that even minor advances to delay progression or ameliorate symptoms might have substantial financial and societal benefits (Winblad et al...

Alzheimer's disease (AD) is a widespread form of dementia that is estimated to affect 44.4 million people worldwide. AD pathology is closely related to the accumulation of amyloid beta (Aβ) peptides in fibrils and plagues, the small oligomeric intermediate species formed during the Aβ peptides aggregation presenting the highest neurotoxicity. This review discusses the recent advances on the Aβ peptides electrochemical characterisation. The Aβ peptides oxidation at a glassy carbon electrode occurs in one or two steps, depending on the amino acid sequence, length and content...

Background: There are several existing systematic reviews of prevalence of dementia for mainland China, Hong Kong and Taiwan, but several studies have been newly reported. The aim of this study is to update prevalence data in this region and test for variation across geographical areas and time periods using the new dataset. Methods: Twenty prevalence studies identified from World Alzheimer Report 2015 (January 2011-March 2015) and an updated search (March 2015-February 2017) were added to the original dataset (N = 76)...

Pain assessment can benefit from observation of pain behaviors, such as guarding or facial expression, and observational pain scales are widely used in clinical practice with nonverbal patients. However, little is known about head movements and postures in the context of pain. In this regard, we analyze videos of three publically available datasets. The BioVid dataset was recorded with healthy participants subjected to painful heat stimuli. In the BP4D dataset, healthy participants performed a cold-pressor test and several other tasks (meant to elicit emotion)...

BACKGROUND: Sundown syndrome (SS) is the onset or worsening of behavioral symptoms in the evening in patients with dementia. OBJECTIVE: To identify the differential clinical profile of patients with dementia who present SS. METHODS: A cross-sectional, case-control observational study was conducted by retrospectively reviewing the medical records of patients with dementia in a specialized Memory Unit. We compared the characteristics of patients with and without SS, including sociodemographic variables, etiology, and severity of the dementia, behavioral symptoms, sleep disorders (considering insomnia and hypersomnia), other diseases and treatments employed...

A subset of C9orf72 repeat expansion-carrying frontotemporal dementia patients display an Alzheimer-like decrease in cerebrospinal fluid amyloid-β (Aβ) biomarker levels. We report that downregulation of C9orf72 in non-neuronal human cells overexpressing amyloid-β protein precursor (AβPP) resulted in increased levels of secreted AβPP fragments and Aβ, while levels of AβPP or its C-terminal fragments (CTFs) remained unchanged. In neuronal cells, AβPP and C83 CTF levels were decreased upon C9orf72 knockdown, but those of secreted AβPP fragments or Aβ remained unchanged...

Gamma oscillations that occur within the entorhinal cortex-hippocampal circuitry play important roles in the formation and retrieval of memory in healthy brains. Recent studies report that gamma oscillations are impaired in the entorhinal-hippocampal circuit of Alzheimer's disease (AD) patients and AD animal models. Here we review the latest advancements in studies of entorhinal-hippocampal gamma oscillations in healthy memory and dementia. This review is especially salient for readers in Alzheimer's research field not familiar with in vivo electrophysiology...

In the advanced stages of illness, patients often face challenging decisions regarding their treatment and overall medical care. Terminal ill patients are commonly affected by infections. However, in palliative care, the use of antimicrobials can be an ethical dilemma. Deciding whether to treat, withhold, or withdraw the antimicrobial treatment for an infection can be difficult. Antimicrobial administration can lead to adverse outcomes but the two main benefits, longer survival and symptom relief, are the main reasons why physicians prescribe antimicrobial when treating terminally ill patients...

BACKGROUND: Underlying psychiatric conditions may affect outcomes of surgical treatment for colorectal cancer (CRC) because of complex clinical presentation and treatment considerations. We hypothesized that patients with psychiatric illness (PSYCH) would have evidence of advanced disease at presentation, as manifested by higher rates of colorectal surgery performed in the presence of obstruction, perforation, and/or peritonitis (OPP-surgery). MATERIALS AND METHODS: Using data from the 2007-2011 National Inpatient Sample, we identified patients with a diagnosis of CRC undergoing colorectal surgery...

Dementia is any decline in cognition that is significant enough to interfere with independent, daily functioning. Dementia is best characterized as a syndrome rather than as one particular disease. The causes of dementia are myriad and include primary neurologic, neuropsychiatric, and medical conditions. It is common for multiple diseases to contribute to any one patient's dementia syndrome. Neurodegenerative dementias, like Alzheimer disease and dementia with Lewy bodies, are most common in the elderly, while traumatic brain injury and brain tumors are common causes in younger adults...

BACKGROUND: The relationship between dementia and type 2 diabetes mellitus (T2DM) in older adults is well established in the literature. However, there have been few studies on this relationship in older adults living in low- and middle-income countries, and most demographic projections predict that older adult population will increase substantially in these regions by 2050. METHODS: In this study, older adults with T2DM attending a tertiary health facility were examined and compared with community-dwelling older adults without T2DM...

Recent advances have led to a greater understanding of how alcohol alters the brain, both in acute stages (intoxication and alcohol withdrawal) and in chronic misuse. This review focuses on the current understanding of how alcohol affects the brain in cirrhosis patients with and without hepatic encephalopathy. Chronic alcohol use is associated with nutritional deficiencies, dementia, cirrhosis, and decompensating events such as hepatic encephalopathy. Direct toxicity on brain tissue, induction of neuro-inflammation, and alcohol's alterations of the gut microbiome are possible mechanisms for the clinical features of hepatic encephalopathy associated with alcohol use...

The Traditional Chinese Medicine (TCM) theory that "kidneys give rise to marrow, and the brain is the sea of marrow" has been a guide for the clinical application of kidney, qi and blood tonics for prevention and treatment of dementia and improvement in memory. As low resistance end-organs, both the brain and the kidneys are subjected to blood flow of high volumes throughout the cardiac cycle. Alzheimer's disease and vascular dementia are two common causes of dementia, and it is increasingly recognized that many older adults with dementia have both AD and vascular pathologies...

OBJECTIVES: An increased amount of functional dependence has been reported among residents living in nursing homes. Among others, feeding dependence is one of the most complex needs to satisfy: behind the attempt to personalise meals with individual preferences and clinical regimens, all residents require help at the same moment and for long periods of time, three or more times a day. With the intent of debating policy implications, the aims of this study were to advance the knowledge in the field of feeding dependence prevalence and predictors in Italy, a country where life expectancy is among the highest in the World...

The Alzheimer's Disease Assessment Scale's cognitive subscale (ADAS-Cog) has been widely used as an outcome measure in Alzheimer's Disease (AD) clinical trials. In its original form (ADAS-Cog11), the scale has been used successfully in mild-to-moderate AD dementia populations, but its use is more limited in the study of earlier disease (mild cognitive impairment [MCI] or mild dementia due to AD) owing to lack of appropriate sensitivity of some items. With recent focus on earlier treatment, efforts have focused on the development of more sensitive tools, including the Clinical Dementia Rating-Sum of Boxes (CDR-SB), a global assessment tool to evaluate both cognition and function...

Hypertension is a major risk factor for many common chronic diseases, such as heart failure, myocardial infarction, stroke, vascular dementia and chronic kidney disease. Pathophysiological mechanisms contributing to the development of hypertension include increased vascular resistance, determined in large part by reduced vascular diameter due to increased vascular contraction and arterial remodelling. These processes are regulated by complex interacting systems such as the renin angiotensin aldosterone system (RAAS), sympathetic nervous system, immune activation and oxidative stress, which influence vascular smooth muscle function...
