BACKGROUND: Although people with intellectual disability (ID) and people with dementia have high drug prescription rates, there is a lack of studies investigating drug use among those with concurrent diagnoses of ID and dementia. AIM: To investigate the use of antipsychotics, benzodiazepine derivatives, and drugs recommended for dementia treatment (anticholinesterases [AChEIs] and memantine) among people with ID and dementia. METHODS AND PROCEDURES: Having received support available for people with ID and/or autism spectrum disorder (ASD) was used as a proxy for ID...

BACKGROUND: Parkinson's disease is the second most common neurodegenerative disorder for which old age is the best known risk. The proportion of elderly in the world is increasing, resulting in larger pool of people at risk for Parkinson's disease. Several other neurodegenerative disorders also produce Parkinson syndrome. Distinguishing between those variants is only possible with pathological examination of brain. No autopsy confirmed study of 80 years and older onset in parkinsonism cases has been reported...

The British Association for Psychopharmacology coordinated a meeting of experts to review and revise its previous 2011 guidelines for clinical practice with anti-dementia drugs. As before, levels of evidence were rated using accepted standards which were then translated into grades of recommendation A-D, with A having the strongest evidence base (from randomised controlled trials) and D the weakest (case studies or expert opinion). Current clinical diagnostic criteria for dementia have sufficient accuracy to be applied in clinical practice (B) and both structural (computed tomography and magnetic resonance imaging) and functional (positron emission tomography and single photon emission computerised tomography) brain imaging can improve diagnostic accuracy in particular situations (B)...

Recently, combination therapy involving cholinesterase (ChE) inhibitor with other neuroprotective agents has shown better desirable effect in the management/prevention of dementia but limited information is available on their effect with dietary polyphenols. Hence, this study sought to assess the combined pretreatment effect of curcumin, the major polyphenolic compound of turmeric (Curcuma longa) rhizomes, with donepezil, a cholinesterase inhibitor, on cognitive function in scopolamine-induced memory impairment in rats...

Alzheimer's disease (AD) is the primary cause of age-related dementia. Effective strategies to prevent and treat AD remain elusive despite major efforts to understand its basic biology and clinical pathophysiology. Significant investments in therapeutic drug discovery programs over the past two decades have yielded some important insights but no blockbuster drugs to alter the course of disease. Because significant memory loss and cognitive decline are associated with neuron death and loss of gray matter, especially in the frontal cortex and hippocampus, some focus in drug development has shifted to early prevention of cellular pathology...

Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...

Insulin is now considered to be a new drug candidate for treating dementias, such as Alzheimer's disease, whose pathologies are linked to insulin resistance in the brain. Our recent work has clarified that a noncovalent strategy involving cell-penetrating peptides (CPPs) can increase the direct transport of insulin from the nasal cavity into the brain parenchyma. The present study aimed to determine whether the brain insulin level increased by intranasal coadministration of insulin with the CPP penetratin has potential for treating dementia...

INTRODUCTION AND HYPOTHESIS: Anticholinergic medication is the medical treatment for overactive bladder (OAB). These drugs can act on the central nervous system and can lead to cognitive decline, dementia, and potentially death. Patients taking drugs with anticholinergic effects increase their anticholinergic burden-defined as the cumulative effect of taking one or more drugs that can have adverse effects. When prescribing anticholinergic medication for the elderly, we must choose the right drug...

Dementia is a major concern among growing chronic diseases in the aging society and its association with polypharmacy has not been adequately assessed. The objective of this study was to determine the association between polypharmacy and dementia through multiple statistical approaches. We conducted a nested case-control study for newly diagnosed dementia cases using the South Korean National Health Insurance Service sample cohort database (2002-2013, n = 1,025,340). Interactions between polypharmacy (an average use of ≥5 prescription drugs daily) and comorbidities or potentially inappropriate medications (PIMs) were tested...

Memantine, an uncompetitive N-methyl-D-aspartate receptor antagonist, and the cholinesterase inhibitor, donepezil, are approved in most countries for treating moderate-to-severe Alzheimer's disease (AD). These drugs have different molecular targets; thus, it is expected that the effects of combined treatment would be synergistic. Some reports do show memantine/donepezil synergy in ameliorating cognition in AD model animals, but their combined effects on behavioral and psychological symptoms of dementia (BPSD)-like behaviors have not been addressed...

BACKGROUND: Antipsychotics and other psychotropics are frequently used to treat neuropsychiatric symptoms in patients with dementia, even though the evidence for effect is limited. Concerns have been raised about the safety of antipsychotics, but concomitant use of multiple psychotropic drug classes (psychotropic polypharmacy) may also pose a risk for patients. OBJECTIVE: To investigate the prevalence and predictors associated with use of psychotropic polypharmacy in patients with dementia...

BACKGROUND: Citicoline can have beneficial effects both in degenerative and in vascular cognitive decline in a variety of ways (apoptosis inhibition, neuroplasticity potentiation, phospholipid, and acetylcholine (ACh) synthesis). Acetylcholinesterase inhibitors (AChEIs) have been used for treatment of Alzheimer's disease (AD). When co-administered with cholinergic precursors, they are able to increase the intrasynaptic levels of ACh more than when the single drugs given alone. OBJECTIVE: The aim of the present study was to show the effectiveness of oral citicoline plus AChEIs in patients affected with AD...

Impaired cholinergic neurotransmission associated with cognitive dysfunction occurs in various mental disorders of different etiologies including Alzheimer's disease and postalcoholic dementia and others. To address the question whether there exists a common endophenotype with a defined genetic and/or epigenetic signature causing mental dysfunction in these disorders, we investigated 2 generations of offspring born to alcohol-treated mothers. Here, we show that memory impairment and reduced synthesis of acetylcholine occurs in both F1 (exposed to ethanol in utero) and F2 generation (never been exposed to ethanol)...

BACKGROUND: Benzodiazepines are a widely used medication in developed countries, particularly among elderly patients. However, benzodiazepines are known to affect memory and cognition and might thus enhance the risk of dementia. The objective of this review is to synthesize evidence from observational studies that evaluated the association between benzodiazepines use and dementia risk. SUMMARY: We performed a systematic review and meta-analysis of controlled observational studies to evaluate the risk of benzodiazepines use on dementia outcome...

The objective of this study is to examine the frequency, development, concomitants, and risk factors of falls in a population-based incident Parkinson's disease (PD) cohort. One hundred eighty-one drug-naïve patients with incident PD and 173 normal controls recruited from the Norwegian ParkWest study were prospectively monitored over 7 years. Information on falls was obtained biannually from patients, and at baseline and after 1, 3, 5, and 7 years of follow-up in control subjects. Generalized estimating equation models for correlated data were applied to investigate concomitant features of falls and risk factors for incident falls during 7 years of follow-up in PD...
