Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative, clinically heterogeneous syndrome pathologically overlapping with frontotemporal dementia. To date, therapeutic trials in animal models have not been able to predict treatment response in humans, and the revised ALS Functional Rating Scale, which is based on coarse disability measures, remains the gold-standard measure of disease progression. Advances in neuroimaging have enabled mapping of functional, structural, and molecular aspects of ALS pathology, and these objective measures may be uniquely sensitive to the detection of propagation of pathology in vivo...

PURPOSE: Insomnia is problematic for older adults. After behavioral modifications fail to show adequate response, pharmacologic options are used. The pharmacokinetics of agents used to treat insomnia may be altered. This review focuses on the safety and efficacy of medications used to treat insomnia. METHODS: A literature search of Medline, PubMed, and Embase was conducted (January 1966-June 2016). It included systematic reviews, randomized controlled trials, observational studies, and case series that had an emphasis on insomnia in an older population...

At the First WHO Ministerial Conference on Global Action Against Dementia in March, 2015, 160 delegates, including representatives from 80 WHO Member States and four UN agencies, agreed on a call for action to reduce the global burden of dementia by fostering a collective effort to advance research. To drive this effort, we completed a globally representative research prioritisation exercise using an adapted version of the Child Health and Nutrition Research Initiative method. We elicited 863 research questions from 201 participants and consolidated these questions into 59 thematic research avenues, which were scored anonymously by 162 researchers and stakeholders from 39 countries according to five criteria...

Clinical treatment for vascular dementia still remains a challenge mainly due to Blood-Brain Barrier (BBB). Here, a micelle based on polysialic acid (PSA) which is a hydrophilic and endogenous carbohydrate polymer, was designed to deliver calmodulin antagonist for therapy of vascular dementia. PSA was firstly chemically conjugated with octadecylamine (ODA), and the obtained PSA-ODA copolymer could self-assemble into micelle in aqueous solution with a 120.0 μg/mL critical micelle concentration. The calmodulin antagonist loaded PSA-ODA micelle, featuring sustained drug release behaviour over a period of 72 h with 3...

Gastrodin (GAS), which is extracted from the Chinese herbal medicine Gastrodia elata Blume, has long been used to improve stroke, epilepsy, dizziness and dementia. However, the effects and underlying mechanisms of GAS on subacute phase cerebral ischemia‑reperfusion (I/R) injury remain unknown. The aim of the present study was to investigate the effects and mechanisms of GAS on cerebral I/R injury in rats. The rats were pretreated with GAS by gavage for 7 days followed by I/R surgery, and were then treated with GAS for 7 days after I/R surgery...

INTRODUCTION: Cannabis use is very frequent in bipolar disorder and has been found to increase the duration and frequency of manic symptoms while decreasing those of depression. Bipolar patients who use cannabis were shown to have poorer compliance to treatment, more symptoms that are psychotic and a worse prognosis than patients who do not. In this study, we have evaluated the importance of cannabis use among bipolar patients admitted to the Psychiatric Hospital of the Cross, Lebanon (Hôpital Psychiatrique de la Croix [HPC]) as well as the clinical differences between cannabis users and non-users...

In the late 1980s, several observational studies and meta-analyses suggested that hormone replacement therapy (HRT) was beneficial for prevention of osteoporosis, coronary heart disease, dementia and decreased all-cause mortality. In 1992, the American College of Physicians recommended HRT for prevention of coronary disease. In the late 1990s and early 2000s, several randomized trials in older women suggested coronary harm and that the risks, including breast cancer, outweighed any benefit. HRT stopped being prescribed at that time, even for women who had severe symptoms of menopause...

Sex-steroid hormones are primarily involved in sexual differentiation and development and are thought to underlie processes related to cognition and emotion. However, divergent results have been reported concerning the effects of hormone administration on brain structure including side effects like brain atrophy and dementia. Cross-sex hormone therapy in transgender subjects offers a unique model for studying the effects of sex hormones on the living human brain. In this study, 25 Female-to-Male (FtM) and 14 Male-to-Female (MtF) subjects underwent MRI examinations at baseline and after a period of at least 4-months of continuous cross-sex hormone administration...

OBJECTIVES: Behavioral and psychological symptoms have a high prevalence in dementia. They include mood disorders, psychotic disorders and behavioral disorders such as aggression or screaming. Despite a number of side effects and an increased mortality, antipsychotic drugs are widely prescribed for treatment of this disorder. In France, this increased risk of mortality led in 2009 to the adoption of guidelines concerning all antipsychotics. The guidelines propose a sensible use of antipsychotics after the establishment of non-pharmacological measures...

OBJECTIVES: Optimal selection of idiopathic normal pressure hydrocephalus (iNPH) patients for shunt surgery is challenging. Disease State Index (DSI) is a statistical method that merges multimodal data to assist clinical decision-making. It has previously been shown to be useful in predicting progression in mild cognitive impairment and differentiating Alzheimer's disease (AD) and frontotemporal dementia. In this study, we use the DSI method to predict shunt surgery response for patients with iNPH...

It cannot be assumed by healthcare providers that transgender people routinely receive care and treatment that is of the quality and sensitivity that should be expected. In particular there are concerns from within the transgender community that they experience discrimination and disrespect from both individual practitioners and the healthcare system as a whole. This causes an avoidance of contact that is undesirable for both users and providers of healthcare services. Older transgender people are vulnerable to a range of mental health problems and, like all elderly, increasingly to dementia; failure to access specialist services in a timely manner may result in unnecessary distress and potentially to crisis...

Importance: A growing body of evidence supports a link between androgen deprivation therapy (ADT) and cognitive dysfunction, including Alzheimer disease. However, it is currently unknown whether ADT may contribute to the risk of dementia more broadly. Objective: To use an informatics approach to examine the association of ADT as a treatment for prostate cancer with the subsequent development of dementia (eg, senile dementia, vascular dementia, frontotemporal dementia, and Alzheimer dementia)...

Objective Limitation of Medical Treatment (LMT) forms are an essential element of end-of-life care. Decision making around LMT is complex and often involves patients with dementia. Despite the complexity, junior doctors frequently play a central role in completing LMT forms. The present study sought perspectives from a range of stakeholders (hospital clinicians, medical education personnel, legal and advocacy staff) about junior doctors' roles in completing LMT forms in general and for patients with dementia...

Nowadays more than 24 million people suffer from Alzheimer's disease (AD) that is the most common progressive cause of dementia. Molecular mechanisms of neurodegeneration in Alzheimer's disease is closely link with accumulation of misfolded proteins in the lumen of the endoplasmic reticulum (ER). Deposition of senile plaques is one of the main feature of Alzheimer's disease as well as is strictly correlated with impairment of cognitive abilities. The accumulation of misfolded proteins in the lumen of the ER triggers activation of the ER stress, and subsequently unfolded protein response (UPR) signaling branches, which consists of a cascade of events on the molecular level of nerve cell...

Cholinesterases (ChE) are common targets of organophosphate (OP) pesticides and play a critical role in the pathology of some dementias. While chlorpyrifos (CPF) remains one of the most commonly used OPs in the world, numerous investigations have reported its neurotoxic potential and highlighted behavioral disturbances upon its administration. Rivastigmine currently serves to treat Alzheimer's disease, but it may induce cholinergic overstimulation in non-demented individuals. The present investigation aimed to compare the acute and delayed effects caused by both ChE inhibitors in adult C57BL/6 male mice...

Type 2 diabetes (T2D) is a highly concerning public health problem of the twenty-first century. Currently, it is estimated that T2D affects 422 million people worldwide with a rapidly increasing prevalence. During the past two decades, T2D has been widely shown to have a major impact in the brain. This, together with the cognitive decline and increased risk for dementia upon T2D, may arise from the complex interaction between normal brain aging and central insulin signaling dysfunction. Among the several features shared between T2D and some neurodegenerative disorders (e...
