INTRODUCTION: The clinical meaningfulness of Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) subscore change is disputed. We compared 2- to 4-point ADAS-Cog changes with changes in Goal Attainment Scaling (GAS) and everyday function across initial ADAS-Cog scores and treatment responses. METHODS: This exploratory analysis evaluated mild-moderate Alzheimer's disease patients treated with donepezil (12 months) or galantamine (8 months). Clinical meaningfulness was defined as concomitant ADAS-Cog and GAS changes of ±3 points and/or functional improvement...

Magnetic particles (MPs) have been widely used in biological applications in recent years as a carrier for various molecules. Their big advantage is in repeated use of immobilized molecules including enzymes. Acetylcholinesterase (AChE) is an enzyme playing crucial role in neurotransmission and the enzyme is targeted by various molecules like Alzheimer's drugs, pesticides and warfare agents. In this work, an electrochemical biosensor having AChE immobilized onto MPs and stabilized through glutaraldehyde (GA) molecule was proposed for assay of the neurotoxic compounds...

BACKGROUND: Treatment for neuropsychiatric symptoms (NPS) in dementia is insufficient. Antipsychotics and acetylcholinesterase inhibitors are used generating symptomatic improvements in behavior and cognition, but few studies have investigated their effect on Alzheimer's disease (AD) biomarkers in cerebrospinal fluid (CSF). OBJECTIVE: This is a secondary analysis based on an earlier clinical trial comparing the treatment effects on NPS. The aim of this study was to examine whether treatment with risperidone and galantamine affect levels of the biomarkers T-Tau, P-Tau, Aβ1-42, and Aβ42/40-ratio in CSF...

The aging world population had led to an increase in the prevalence of Alzheimer's disease (AD). The drugs used to slow down the onset of AD, galantamine, donepezil, rivastigmine and memantine, are generally well-tolerated. However, drug interactions between these drugs and other drugs are an important aspect of patient safety that should be borne in mind, particularly given the high burden of polypharmacy in the elderly. The aim of this review is to provide an updated review of clinically significant drug-drug interactions concerning drugs approved for AD...

INTRODUCTION: Delayed encephalopathy due to carbon monoxide (CO) poisoning can even occur in patients with mild symptoms of acute CO poisoning. Some cases taking conventional hyperbaric oxygen (HBO) therapy or steroid-pulse therapy may be insufficient, and AchEI may be effective. PATIENT CONCERNS AND DIAGNOSES: We report two cases of delayed encephalopathy after acute CO poisoning involving two women aged 69 (Case 1) and 60 years (Case 2) whose cognitive function improved with acetylcholinesterase inhibitor (AchEI) treatment...

Behavioral and psychological symptoms of dementia (BPSD) occur in up to 80% of AD patients and represent one of the largest factors contributing to caregiver burden. To analyze the effect of galantamine on BPSD and caregiver burden, we treated a total of 50 patients with mild AD for 12 weeks and evaluated them using the Neuropsychiatric Inventory (NPI) and Japanese version of the Zarit Caregiver Burden Interview (ZBI). We also performed regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) at baseline using three-dimensional sterotatic surface projections...

Culinary mushroom Pleurotus pulmonarius has been popular in Asian countries. In this study, the anti-oxidant, cholinesterase, and inflammation inhibitory activities of methanol extract (ME) of fruiting bodies of P. pulmonarius were evaluted. The 1,1-diphenyl-2-picryl-hydrazy free radical scavenging activity of ME at 2.0 mg/mL was comparable to that of butylated hydroxytoluene, the standard reference. The ME exhibited significantly higher hydroxyl radical scavenging activity than butylated hydroxytoluene. ME showed slightly lower but moderate inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase than galantamine, a standard AChE inhibitor...

A novel series of tacrine derivatives containing sulfonamide group were synthesized and their inhibitory effects on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) were evaluated. The result showed that all the synthesized tacrine-sulfonamides (VIIIa-o) exhibited inhibitory activity on both cholinesterases. VIIIg showed the highest inhibitory activity on AChE IC50=0.009μM. This value is 220-fold greater than that of galantamine (IC50=2.054μM) and 6-fold greater than tacrine (IC50=0.055μM). VIIIf displayed the strongest inhibition of BuChE (IC50=2...

Emma L Wightman
Our current therapeutic drugs for Alzheimer's disease are predominantly derived from the alkaloid class of plant phytochemicals. These drugs, such as galantamine and rivastigmine, attenuate the decline in the cholinergic system but, as the alkaloids occupy the most dangerous end of the phytochemical spectrum (indeed they function as feeding deterrents and poisons to other organisms within the plant itself), they are often associated with unpleasant side effects. In addition, these cholinesterase inhibiting alkaloids target only one system in a disorder, which is typified by multifactorial deficits...

BACKGROUND: Cholinesterase inhibitors (ChEIs) are prescribed to dementia patients despite their poor tolerance. Low tolerability potentially reduces persistence and adherence, while inducing switching between medications. Comparisons of these utilization measures contribute to knowledge of the relative tolerability of these medications. AIM: The aim was to compare persistence, adherence, and switching between donepezil, galantamine, oral rivastigmine, and rivastigmine patch...

OBJECTIVES: In this work, we hypothesized whether galantamine could interact with the cholinergic anti-inflammatory pathway and modulate immunity this way. BACKGROUND: Galantamine is a drug used for the therapy of Alzheimer disease. The drug inhibits enzyme acetylcholinesterase in the central nervous system, which causes better availability of neurotransmitter acetylcholine. METHODS: In the experiment, we immunized BALB/c laboratory mice by keyhole limpet hemocyanin (KLH) in combination with galantamine in a dose 0...

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)...

OBJECTIVES: Urinary incontinence (UI) is more prevalent in the elderly populations with dementia than without dementia, and Alzheimer's disease (AD) is the most common cause of dementia. Urinary incontinence may complicate AD morbidity and mortality. Therefore, this study aimed to evaluate the prevalence and annual incidence and determine the risk possibility of UI, which is the main type of incontinence in patients with AD in Taiwan. METHODS: A total of 933 patients with AD were included in the study cohort, and a total of 2799 patients without AD by 1:3 proportion compared to the study cohort were used as a matched cohort...

BACKGROUND: Alzheimer's disease (AD) therapy is based on several natural and synthetic compounds that act as acetylcholinesterase (AChE) and N-methyl-D-aspartate receptor (NMDA) ligands that have limited efficiency in relieving AD symptoms. Recent studies show that inhibitors isolated from Mentha spicata L. subsp. spicata are promising for AD therapy. OBJECTIVE: We aimed to identify novel and more potent phytopharmaceutical compounds for AD treatment by taking into account the compounds from Mentha spicata L...

AIM: To evaluate the therapeutic effects of switching from one acetylcholinesterase inhibitor (ChEI), donepezil, galantamine or rivastigmine, to another in Alzheimer's disease patients. METHODS: We retrospectively enrolled 171 Alzheimer's disease patients, whose ChEI medication was changed. The patients were evaluated on three major aspects of dementia - cognitive, affective and activities of daily living (ADL) measures - at 6 months (M) before the drug switch, at the time of drug switch (baseline), and at 3 M and 6 M after the drug switch...
