BACKGROUND: HIV+ patients on highly active antiretroviral therapy (HAART) with suppressed viral loads have a low incidence of HIV-associated dementia, but increased prevalence of milder forms of HIV-associated neurocognitive disorders (HAND). These milder forms of HAND are often associated with minimal histological abnormalities, and their pathophysiology is unclear. Comorbidities, altered amyloid metabolism, accelerated brain aging, and activated interferon responses are suspected to play a role in HAND pathogenesis in HAART-treated persons...

Some observational studies raised concern that statins may cause memory impairment, leading to a US Food and Drug Administration warning. Similar questions were raised regarding proprotein convertase subtilisin/kexin-type 9 inhibitors (PCSK9i) and neurocognitive function. No prospectively designed study has evaluated the relationship between long-term PCSK9i use and cognition changes. Patients with prior cardiovascular disease treated with maximally tolerated statin enrolled in FOURIER (the randomized, double-blind, placebo-controlled cardiovascular outcome study of the PCSK9i evolocumab) could participate in this prospective assessment of cognitive function (EBBINGHAUS)...

Multimorbidity and polypharmacy are increasingly prevalent across healthcare systems and settings as global demographic trends shift towards increased proportions of older people in populations. Numerous studies have demonstrated an association between polypharmacy and potentially inappropriate prescribing (PIP), and have reported high prevalence of PIP across settings of care in Europe and North America and, as a consequence, increased risk of adverse drug reactions, healthcare utilization, morbidity and mortality...

BACKGROUND: Alzheimer's disease (AD), the most common disease causing dementia, is linked to increased mortality. However, the effect of antipsychotic use on specific causes of mortality has not yet been investigated thoroughly. METHODS: Utilizing the Danish nationwide registers, we defined a cohort of patients diagnosed with AD. Utilizing separate Cox regressions for specific causes of mortality, we investigated the effects of cumulative antipsychotic dosage after diagnosis and current antipsychotic exposure in the time period 2000-2011...

BACKGROUND: Studies indicate that people with dementia do not receive the same amount of analgesia after a hip or pelvic fracture compared to those without cognitive impairment. However, there is no systematic review that shows to what extent drug-based pain management is performed for people with dementia following a hip or pelvic fracture. The aim of this systematic review was to identify and analyse studies that investigate drug-based pain management for people with dementia with a hip or pelvic fracture in all settings...

Whether antiplatelet agents have a preventive effect on cognitive function remains unknown. We examined the potential association between the use of cilostazol, an antiplatelet agent and cyclic adenosine monophosphate phosphodiesterase 3 inhibitor, and the risk of dementia in an Asian population. Patients initiating cilostazol therapy between 1 January 2004 and 31 December 2009 without a prior history of dementia were identified from Taiwan's National Health Insurance database. Participants were stratified by age, sex, comorbidities, and comedication...

PURPOSE: Previous studies suggest an association between use of anticholinergic drugs in elderly patients and cognitive impairment. However, there are still limited data on the association of anticholinergic drug use and cognitive impairment as well as contribution of individual drugs to anticholinergic load using large, well-documented patient cohorts treated in geriatric units from Europe. METHODS: We investigated 797,440 prescriptions to 89,579 hospitalized patients treated in geriatric units within the GiB-DAT database...

BACKGROUND: Neuropsychiatric symptoms of dementia are often treated through the prescription of one or more psychotropic medications. However, limited efficacy and potential harmful side-effects has resulted in efforts to reduce the use of psychotropic medication in this population, particularly for those living in long-term care. OBJECTIVES: This study sought to describe the pattern of central nervous system medication usage in older adults with dementia living in long-term care; assess the appropriateness of prescribing against Beers criteria; and detect potential drug interactions from co-administered medications...

Agitation and aggression in adult psychiatric patients with psychoses and in persons with dementia increase the burden of disease and frequently cause hospitalization. The implementation of currently available management strategies and the development of new ones is hindered by inconsistent terminology that confuses agitation with aggression. This confusion is maintained by many rating scales that fail to distinguish between these two syndromes. We review the frequently used rating scales with a particular focus on their ability to separate agitation from aggression...

Dementia of Alzheimer disease (AD) type affects memory, thinking and behavior. Researchers believe that changes in the brain may begin 10-20 years before symptoms appear and AD is diagnosed. The need to diagnose and treat the devastating disease at an early stage is critical to manage and treat AD. Unfortunately, the lack of validated biomarkers limits the possibility of the earlier stages of AD. The advance of nanotechnology could offer huge opportunities in early-stage diagnosis and well treatment of AD. Biocompatible nanoparticles with diameter in the range of 1-100 nm could be used as targeted delivery system for drugs (e...

Alzheimer's Disease (AD) is a global health issue given the increasing prevalence rate and the limitations of drug effects. As a consequent, non-pharmacological interventions are of importance. Music therapy (MT) is a non-pharmacological way with a long history of use and a fine usability for dementia patients. In this review, we will summarize different techniques, diverse clinical trials, and the mechanisms of MT as it is helpful to the cognition in AD, providing reference for future research. Many articles have demonstrated that MT can reduce cognitive decline especially in autobiographical and episodic memories, psychomotor speed, executive function domains, and global cognition...

BACKGROUND: Alzheimer's disease (AD) is one of the most common lethal neurodegenerative disorders having impact on the lives of millions of people worldwide. The disease lacks effective treatment options and the unavailability of the drugs to cure the disease necessitates the development of effectual anti-Alzheimer drugs. Several mechanisms have been reported underlying the association of the two disorders, diabetes and dementia, one among which is the insulin-degrading enzyme (IDE) which is known to degrade insulin as well beta-amyloid peptides...

The chromosome 9 open reading frame 72 (c9orf72) gene contains a hexanucleotide (GGGGCC) repeat expansion responsible for many cases of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The mutant intronic RNA forms "foci" within nuclei, but the connection between transcript expression, foci, and biochemical disease mechanisms is unclear. Knowing the absolute numbers of cellular RNAs, in any system, is important for understanding the molecular mechanisms of natural physiology, disease, and drug action...

Proton pump inhibitors (PPI) are among the safest class of drugs used by all care providers, including gastroenterologists. They are the mainstay in treatment of acid-related disease, in particular, gastroesophageal reflux disease. Without them, many patients would experience a major decrement in their quality of life. However, no drug is without side effects or adverse events. In the past decade, numerous reports, principally case control studies and meta-analyses, have raised questions about important adverse events related to the use of PPIs...

OBJECTIVE: Among elderly individuals with dementia, the use of antipsychotics has been associated with serious adverse events including ischemic stroke and death. Multiple medications can interact with antipsychotics and increase the risk of such adverse events. The purpose of this retrospective, longitudinal cohort study was to estimate the prevalence of potential antipsychotic drug interactions and their effect on increasing the risk of death among cognitively impaired elderly individuals treated with antipsychotics...

To investigate the role of the P2X7 receptor in learning and memory dysfunction induced by HIV-1 envelope glycoprotein gp120 (gp120), we established HIV-1-associated dementia (HAD) animal models by intracerebroventricular (ICV) infusion of gp120 in rats. We observed gp120-induced cognitive dysfunction in the radial arm water maze test. Results showed that rats in the gp120 groups had longer escape latencies and more errors compared to those in the control group. For example, the average trial time in the 50-ng/day-gp120 group on day eight (16...

The current pharmacological approach to Alzheimer's disease (AD) treatment, mostly based on acetylcholinesterase inhibitors (AChEIs), is being revisited, especially in terms of the temporal frames and the potential benefits of their noncanonic actions, raising the question of whether inhibitors of AChE might also act in a disease-modifying manner. Besides, in the last decades, the pharmacophoric moieties of known AChEIs have been covalently linked to other pharmacophores in the pursuit of multitarget hybrid molecules that are expected to induce long-lasting amelioration of impaired neurotransmission and clinical symptoms but also to exert disease-modifying effects...

BACKGROUND: The use of antipsychotic medications (APMs) in nursing home residents in the U.S. is an increasingly prominent issue and has been associated with increased risk of hospitalization, cardiovascular events, hip fractures, and mortality, among other adverse health events. The Food and Drug Administration has placed a black box warning on these drugs, specifying that they are not meant for residents with dementia, and has asked providers to review their treatment plans. The purpose of this systematic PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses)-based review was to summarize original research studies on facility level characteristics contributing to the use of antipsychotics in nursing homes across the United States, in order to investigate the variation of use...
