BACKGROUND/AIMS: Reduced clinical effect on cognitive decline in dementia by acetylcholinesterase inhibitors (AChEIs) may be due to concurrent use of drugs with anticholinergic properties. The aim was to analyze the incidence of AChEI use and comedication with drugs with anticholinergic properties and other potential unfavorable effects. METHODS: A prospective study applying drug use data from the Norwegian Prescription Database. Anticholinergic Drug Scale (ADS) scores were used as a measure of overall anticholinergic burden...

Anticholinergic drug use is common in older adults and has been related to increased dementia risk. This suggests that users of these drugs may experience accelerated cognitive decline. So far, however, longitudinal data on this topic are absent and the available evidence is inconclusive with respect to effects on specific cognitive domains due to suboptimal control of confounding variables. We investigated whether anticholinergic medication use is associated with cognitive decline over 6 years in a population-based study of older adults (aged 60-90; n = 1473) without dementia...

BACKGROUND: Patients with psychotic disorders are often treated with numerous medications, many of which have anticholinergic activity. We assessed cognition in relation to the cumulative anticholinergic burden of multiple drugs included in treatment regimens of participants from the Bipolar-Schizophrenia Network on Intermediate Phenotypes (B-SNIP) study. METHOD: Clinically stable participants with schizophrenia (n=206), schizoaffective disorder (n=131), and psychotic bipolar disorder (n=146) were examined...

OBJECTIVE: The use of drugs with intrinsic anticholinergic properties is widespread among old age persons. A growing body of evidences suggest that a high anticholinergic burden is associated with physical and cognitive impairment. However, the association between anticholinergic drug use and functional status is still poorly investigated, particularly among subjects with initial cognitive impairment. DESIGN: Cross-sectional study examining the association between drug-related anticholinergic burden and functional status in cognitively healthy (CH) (n=691), mild cognitive impairment (MCI) (n=541) or mild Alzheimer's diseases (AD) (n=1127) subjects...

Assessments of total anticholinergic activity (SAA) in serum are of considerable interest for its potential involvement in cognitive impairment associated with polydrug states in the elderly and other populations. Such estimations have been based on the displacement of radioligand binding in rat brain tissues. The validity of such measurements has been questioned, as a potentially distorting effect of large serum proteins was identified. We sought to develop a modified assay that would be more efficient and free of this potential confound...

Urinary dysfunction (UD) is a common non-motor feature of Parkinson's disease (PD), and might be secondary to neurodegeneration involving cortical and subcortical brain areas. The possible link between UD and cognitive deficits has never been examined in frontal cortex impairment, and is still not completely understood in PD. In the present study, 94 PD patients underwent a comprehensive motor, cognitive and non-motor assessment. It was shown that 55.3% of patients reported UD, of which 17% needed specific urological treatment...

Delirium in older adults is associated with an increased risk for cognitive and functional decline. Multiple risk factors, such as underlying dementia, multiple comorbidities, anticholinergic medication or visual and hearing impairment foster the incidence of delirium. By identification of patients at risk and the initiation of a multiple component delirium prevention program delirium is preventable in 30-40% of all cases. There is broad evidence for comprehensive multicomponent delirium prevention strategies in patient care, but their implementation is still lacking in many hospitals...

Evidence for the efficacy and safety of intravesical onabotulinum toxin A (onabotA) injections has led to them being licensed in many countries, including Korea, for the treatment of patients with urinary incontinence due to neurogenic detrusor overactivity (NDO) resulting from spinal cord injury or multiple sclerosis who are refractory or intolerant to anticholinergic medications. OnabotA injections have an inhibitory effect on acetylcholine release for up to 10 months, with a recommended dose of 200 U. OnabotA treatment has a beneficial effect not only on urinary symptoms, but also on quality of life...

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...

BACKGROUND: Urinary incontinence (UI) is frequently observed in patients with Alzheimer's disease (AD). Although previous works highlight the association between frontal lobe-related function and UI, causal relationship is unclear. OBJECTS: To clarify the longitudinal association between frontal lobe function and the incidence of UI at 1 year in patients with AD. METHODS: The subjects were 215 continent AD patients who attended the Memory Clinic of the National Center for Geriatrics and Gerontology of Japan during the period from March 2011 to December 2014...

Acetylcholine is present in the peripheral and central nervous system, where it is involved in a number of fundamental physiological and biochemical processes. In particular, interaction with muscarinic receptors can cause adverse effects such as dry mouth, drowsiness, mydriasis and cognitive dysfunction. Despite the knowledge that exists regarding these common side-effects, little is known about how anticholinergic medications influence central motor processes and fine motor control in healthy individuals...

PURPOSE: The Drug Burden Index (DBI) is a non-invasive method to quantify patients' anticholinergic and sedative drug burden from their prescriptions. This systematic review aimed to summarise the evidence on the associations between the DBI and clinical outcomes and methodological quality of studies. METHODS: A search in PubMed and Embase (search terms: 'drug', 'burden', and 'index') was performed and experts were contacted. We excluded publications that did not report empirical results or clinical outcomes...

INTRODUCTION: Overactive Bladder (OAB) accounts for 40-70% cases of incontinence. The etiology is unknown though detrusor instability is found in urodynamic evaluation of almost all cases. Detrusor instability or hyperreflexia can be inhibited by direct inhibition of impulses in the pre-ganglionic afferent neuron or by inhibition of bladder pre-ganglionic neurons of the efferent limb of micturition reflex. Transcutaneous Electrical Nerve Stimulation (TENS) is based on the gate control theory of abolishing the local micturition reflex arc...

Antipsychotic medication is an essential component for treating schizophrenia, which is a serious mental disorder that affects approximately 1% of the global population. Olanzapine (Olz), one of the most frequently prescribed atypical antipsychotics, is generally considered a first-line drug for treating schizophrenia. In contrast to psychotic symptoms, the effects of Olz on cognitive symptoms of schizophrenia are still unclear. In addition, the mechanisms by which Olz affects the neural circuits associated with cognitive function are unknown...

BACKGROUND: Anticholinergic and sedating medications are generally contraindicated in those with cognitive decline. We examined trends in medication use by patients at initial presentation to a rural and remote memory clinic (RRMC) between March 2004 and June 2015 to determine whether patterns of medication use have changed. METHODS: The first 444 patients seen at the RRMC between 2004 and 2015 were included in this analysis. Medication lists were collected at the patient's initial visit, and it was noted whether patients were taking anticholinergic or potentially sedating drugs...
