OBJECTIVE: Increasing evidences suggest that patients with Alzheimer's disease (AD) show not only cognitive impairment but also physical disorder including cardiac dysfunction and sarcopenia. In this study, we investigated whether central angiotensin II, inducer of oxidative stress, led to the organ dysfunction in a mouse model of AD. DESIGN AND METHOD: 5XFAD which is an animal model of AD and C57BL/6 (WT) were each assigned to 1) normal saline and 2) angiotensin II (20 mg/kg/h) groups...

INTRODUCTION: Worldwide, countries are calling for a chronic disease management approach to people with dementia. In response, 'living well' with dementia and 'supported self-care' frameworks are being adopted by advocacy and volunteer organizations, and more attention is being directed towards health and wellness promotion as a critical component for 'living well'. This exploratory study examined the health and wellness self-management behaviors of patients attending a rural and remote memory clinic; and relationships between engaging in health and wellness behaviors and psychological and neuropsychological function, independence in daily activities, and balance...

BACKGROUND: Down's syndrome (DS) is caused by either complete or partial triplication of chromosome 21, affecting approximately 1/1000 live births, and it is widely accepted that individuals with DS are more likely to develop dementia of Alzheimer's disease (DAD) compared with the general population. Recent collaborative genome-wide association studies of large case control data sets of individuals with and without Alzhemier's disease (AD) have revealed new risk variants for dementia, as well as confirming previously identified risk variants...

Recent studies have reported that a rare mutation of triggering receptor expressed on myeloid cells 2 gene (TREM2 [rs75932628-T]) has significantly increased the risk of late-onset Alzhemier's disease (LOAD) in European-descendent population. To date, no study has investigated the association between rare mutations of TREM2 and LOAD risk in non-European population. Here, we sequenced exon2 of TREM2 in the northern Han Chinese population consisting of 1133 patients with LOAD and 1159 control subjects. Although, 4 novel mutations (c...

Polyglutamine diseases are a class of neurodegenerative disorders characterized by expansion of polyglutamine repeats, protein aggregation and neuronal cell death in specific regions of the brain. The expansion of a polyglutamine repeat in the TATA binding protein (TBP) causes a neurodegenerative disease, Spinocerebellar Ataxia 17 (SCA17). This disease is characterized by intranuclear protein aggregates and selective loss of cerebellar neurons, including Purkinje cells. MicroRNAs are small, endogenous, regulatory non-coding RNA molecules that bind to messenger RNAs with partial complementarity and interfere in their expression...

The review focuses on current data on Alzhemier's dementia, a clinical syndrom characterised with acquired deterioration of cognitive functioning and emotional capacities, which impaires everyday activity and quality of life. Alzheimer's dementia is the most common type of dementia in clinical surveys. The diagnosis of Alzheimer's dementia is primarily based on symptoms and signs and memory impairment is clinically most significant. Cholinesterase inhibitors -donepezil, rivastigmine and galantamine are considered to be the first line pharmacotherapy for mild to moderate Alzheimer's disease...

Alzhemier's disease (AD) is a common form of dementia in the ageing population which is characterized by depositions of amyloids and a cholinergic neurotransmission deficit in the brain. Current therapeutic intervention for AD is primarily based on the inhibition of brain acetylcholinesterase (AChE) to restore the brain acetylcholine level. Cryptotanshinone (CT) and dihydrotanshinone (DT) were diterpenoids extracted from Salvia miltiorrhiza Bge. having anti-cholinesterase activity. Here we characterized the inhibition property of these two diterpenoids towards human AChE and butyrylcholinesterase (BChE)...

A pathogenetic feature of Alzhemier disease is the aggregation of monomeric beta-amyloid proteins (Abeta) to form oligomers. Usually these oligomers of long peptides aggregate on time scales of microseconds or longer, making computational studies using atomistic molecular dynamics models prohibitively expensive and making it essential to develop computational models that are cheaper and at the same time faithful to physical features of the process. We benchmark the ability of our implicit solvent model to describe equilibrium and dynamic properties of monomeric Abeta(10-35) using all-atom Langevin dynamics (LD) simulations, since Alphabeta(10-35) is the only fragment whose monomeric properties have been measured...

Pseudoexfoliation syndrome (PEX) is a systemic disorder characterized by the deposition of an abnormal fibrillar material in ocular and various extraocular tissues. It represents the most common identifiable cause of glaucoma (PEX glaucoma = PEXG). Due to similar pathogenetic mechanisms, glaucoma has been called "ocular Alzheimer's disease". PEXG and Alzheimer's disease share common associations such as the higher prevalence of hyperhomocysteinemia in both disorders. In order to investigate the cause of hyperhomocysteinemia in PEXG, we evaluated B-vitamin levels (folate, B12, B6) and their associations with homocysteine (Hcy) in plasma of 70 PEXG patients and 70 control subjects...

Oxidative stress has been implicated in the development of many neurodegenerative diseases such as Parkinson and Alzhemier's disease and is also responsible for aging, artherosclerosis, rheumatoid arthritis and carcinogenesis. Olefins such as dehydroalanines have been shown to inactivate free radicals by forming stabilized free radical adducts. Among these molecules N-acyl dehydroalanines react with and scavenge oxygen and hydroxyl radicals. This study describes the synthesis, characterization and in vitro effects on rat liver lipid peroxidation levels, and DPPH free radical scavenging activities of some N-acyl dehydroalanine derivatives...

Age is the biggest risk factor for the development of neurodegenerative diseases. Consequently, as the population ages it becomes more critical to find ways to avoid the debilitating cost of neurodegenerative diseases such as Alzheimer's. Some of the non-invasive strategies that can potentially slow down the mental decline associated with aging are exercise and use of multi-sensory environmental stimulation. The beneficial effects of both exercise and multi-sensory environmental stimulation have been well-documented, thus it is possible that these strategies can either provide neuroprotection or increase resistance to the development of age-related cognitive problems...

OBJECTIVE: To study the role of beta-amyloid protein 1-42 (A beta 1-42) content in the cerebrospinal fluid (CSF) of Alzheimer disease (AD) patients. METHODS: A beta 1-42 levels were measured with the ELISA method in AD (n = 30), non-AD (NAD, n = 25) and non-dementia (ND, n = 21). RESULTS: The A beta 1-42 mean value for AD was (109.91 +/- 58.78) fmol.L-1. In ND, the A beta 1-42 mean value was (242.40 +/- 142.58) fmol.L-1. The mean value for AD was significantly lower than that of ND...

Even though state governments assume public responsibility for persons with dementia, formal analysis of state laws concerning individuals with Alzhemier's disease and other forms of dementia has been rare. We responded to this by collecting and evaluating state legislation targeted towards individuals with dementia. These laws were collected by searching online statutory archives and were defined by the type of action, year of passage, and legislative purpose. Our research revealed that the legislatures have targeted an average of slightly more than five action towards persons with dementia...

The pathological hallmarks of Alzheimer's disease include neurofibrillary tangles, neuropil threads and neuritic plaques. Neurofibrillary tangles and neuropil threads are comprised of paired helical filaments which are themselves composed of a hyperphosphorylated form of the microtubule-associated protein tau. Neuritic plaques are extracellular deposits of aggregated beta amyloid associated with neurites containing hyperphosphorylated tau. The mechanisms by which the neurofibrillary tangles and neuritic plaques develop in Alzhemier's disease are not clear but it is hypothesized that sulphated glycosaminoglycans are important in their formation...

Pyruvate dehydrogenase complex (PDHc), a link between carbohydrate and acetylcholine metabolism, is a regulatory enzyme for glucose and neurotransmitter metabolism in the brain and is reduced in Alzheimer-diseased brain. To study functional consequences of an inhibition of PDHc on muscarinic receptor binding, bromopyruvate, a suicide inhibitor od PDHc, was injected intracerebroventricularly (icv) in rats. Bromopyruvate caused a reduction of PDHc activity in the 3 brain regions examined, however, reaching significance only in the cerebral cortex and the hippocampus and not in the striatum, 24 h after injection...

A clinicoanatomical study was conducted in 218 cases of atherosclerotic dementia. 12 cases (5,5% of the total amount) showed diagnostic errors. Atherosclerotic dementia with Alzhemier-like symptomatology during life was considered to be Alzheimers disease, while Alzheimers disease, complicated by cerebral atherosclerosis as atherosclerotic dementia. Some objective and subjective factors of diagnostic errors were established. Late detection of such patients is considered as one of the risk factors of diagnostic errors during life...
