BACKGROUND: Research suggests that measurable change in cerebrospinal fluid (CSF) biomarkers occurs years in advance of the onset of clinical symptoms (Beckett 2010). In this review, we aimed to assess the ability of CSF tau biomarkers (t-tau and p-tau) and the CSF tau (t-tau or p-tau)/ABeta ratio to enable the detection of Alzheimer's disease pathology in patients with mild cognitive impairment (MCI). These biomarkers have been proposed as important in new criteria for Alzheimer's disease dementia that incorporate biomarker abnormalities...

BACKGROUND: Hospitalization is an opportunity to address various aspects related to management of dementia, including the goals of care to avoid futile care. We studied the prevalence of these factors when patients with dementia are hospitalized. DESIGN: One hundred and thirty-one charts of patients with dementia admitted to a single university-based hospital were retrospectively reviewed. Data were collected and analyzed for age, gender, the severity of dementia, co-morbidities, co-existing vascular dementia, reversible causes of dementia, mental status scores, medications, consultations, procedures, complications, availability of advance directives, decision-maker, code status, and goals of care discussion...

BACKGROUND: Driving in persons with dementia poses risks that must be counterbalanced with the importance of the care for autonomy and mobility. Physicians often find substantial challenges in the assessment and reporting of driving safety for persons with dementia. This paper describes a driving in dementia decision tool (DD-DT) developed to aid physicians in deciding when to report older drivers with either mild dementia or mild cognitive impairment to local transportation administrators...

Mutations in the SNCA gene, which encodes the α-synuclein protein, were the first discovered genetic causes of familial parkinsonism with Lewy pathology. To date, six different SNCA missense mutations as well as multiplications are known to cause parkinsonism. For this review, we performed a literature search to identify all published cases of SNCA-related parkinsonism to provide an updated summary of the clinical and neuropathological features of parkinsonism due to SNCA mutations. Familial parkinsonism associated with SNCA is rare, but α-synuclein aggregation is a core feature of sporadic parkinsonism, including Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy...

Diabetes mellitus (DM) is the most commonly occurring cause of neuropathy around the world and is beginning to grow in countries where there is a risk of obesity. DM Type II, (T2DM) is a common age-related disease and is a major health concern, particularly in developed countries in Europe where the population is aging. T2DM is a chronic disease which is characterised by hyperglycemia, hyperinsulinemia and insulin resistance, together with the body's inability to use glucose as energy. Such metabolic disorder produces a chronic inflammatory state, as well as changes in lipid metabolism leading to hypertriglyceridemia, thereby producing chronic deterioration of the organs and premature morbidity and mortality...

Geissoschizine methyl ether (GM) is one of the indole alkaloids in Uncaria hook, and an active ingredient of yokukansan (YKS) that improves behavioral and psychological symptoms of dementia (BPSD) in patients with several types of dementia. The pharmacological action of GM has been related to various serotonin (5-HT) receptor subtypes. Here we describe previous findings and our own data to review the binding characteristics of GM to the 5-HT receptor subtypes. Competitive receptor-binding assays showed that GM bound the following 5-HT receptor subtypes: 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT4, 5-HT5A, 5-HT6, and 5-HT7...

Certain cellular proteins normally soluble in the living organism under certain conditions form aggregates with a specific cross-β sheet structure called amyloid. These intra- or extracellular insoluble aggregates (fibers or plaques) are hallmarks of many neurodegenerative pathologies including Alzheimer's disease (AD), Huntington's disease, Parkinson's disease, prion disease, and other progressive neurological diseases that develop in the aging human central nervous system. Amyloid diseases (amyloidoses) are widespread in the elderly human population, a rapidly expanding demographic in many global populations...

The use of biomarkers (BMs) for accurate diagnosis of Alzheimer's disease (AD) has been proposed by recent diagnostic criteria; however, their maturity is not sufficient to grant implementation in the clinical routine. A proper diagnostic process requires not only confirmation of the disease but also the exclusion of similar disorders entering differential diagnosis, like dementia with Lewy bodies (DLB). This review is aimed at evaluating the clinical validity of (123)I-ioflupane brain single photon emission tomography and (123)I-MIBG cardiac scintigraphy as imaging BMs for DLB...

The use of Alzheimer's disease (AD) biomarkers is supported in diagnostic criteria, but their maturity for clinical routine is still debated. Here, we evaluate brain fluorodeoxyglucose positron emission tomography (FDG PET), a measure of cerebral glucose metabolism, as a biomarker to identify clinical and prodromal AD according to the framework suggested for biomarkers in oncology, using homogenous criteria with other biomarkers addressed in parallel reviews. FDG PET has fully achieved phase 1 (rational for use) and most of phase 2 (ability to discriminate AD subjects from healthy controls or other forms of dementia) aims...

White matter lesions (WMLs), also known as leukoaraiosis (LA) or white matter hyperintensities (WMHs), are characterized mainly by hyperintensities on T2-weighted or fluid-attenuated inversion recovery (FLAIR) images. With the aging of the population and the development of imaging technology, the morbidity and diagnostic rates of WMLs are increasing annually. WMLs are not a benign process. They clinically manifest as cognitive decline and the subsequent development of dementia. Although WMLs are important, their pathogenesis is still unclear...

In addition to the deposition of β-amyloid plaques, neurofibrillary tangles composed of aggregated hyperphosphorylated tau are one of the pathological hallmarks of Alzheimer's disease and other neurodegenerative disorders. Until now, our understanding about the natural history and topography of tau deposition has only been based on post-mortem and cerebrospinal fluid studies, and evidence continues to implicate tau as a central driver of downstream neurodegenerative processes and cognitive decline. Recently, it has become possible to assess the regional distribution and severity of tau burden in vivo with the development of novel radiotracers for positron emission tomography (PET) imaging...

The present chapter will review the role of σ1 receptor in learning and memory and neuroprotection , against Alzheimer's type dementia. σ1 Receptor agonists have been tested in a variety of pharmacological and pathological models of learning impairments in rodents these last past 20 years. Their anti-amnesic effects have been explained by the wide-range modulatory role of σ1 receptors on Ca(2+) mobilizations, neurotransmitter responses, and particularly glutamate and acetylcholine systems, and neurotrophic factors...
