Résumé :
Alzheimer’s disease (AD) is the most common form of dementia in old age, and is characterized by prominent impairment of episodic memory. Recent functional imaging studies in AD have demonstrated alterations in a distributed network of brain regions supporting memory function, including regions of the default mode network. Previous positron emission tomography studies of older individuals at risk for AD have revealed hypometabolism of association cortical regions similar to the metabolic abnormalities seen in AD patients. In recent functional magnetic resonance imaging (fMRI) studies of AD, co

Résumé :
Objective:In the field of neurocognitive disorders, the perspective offered by new disease-modifying therapy increases the importance of etiological diagnosis. The prescription of cerebrospinal fluid analysis (CSF) and imaging biomarkers is a common practice in the clinic but is often driven more by personal expertise and local availability of diagnostic tools than by evidence of efficacy and cost-effectiveness analysis. This leads to a widely heterogeneous dementia care across Europe. Therefore, a European initiative is currently being conducted to establish a consensus for biomarker-based di

Résumé :
Subcortical dementia refers to a clinical syndrome characterised by slowing of cognition, memory disturbances, difficulty with complex intellectual tasks such as strategy generation and problem solving, visuospatial abnormalities, and disturbances of mood and affect. The syndrome was first described by Kinnier Wilson, but further progress in development of the concept has occurred only within the past ten years.

Résumé :
Dementia occurs in up to 30% of people with Parkinson's disease and is a major cause of disability. Pathologically, Parkinson's dementia, where dementia follows the onset of parkinsonism by at least one year, overlaps with dementia with Lewy bodies. We review the functional impact, definitions, neuropsychology, epidemiology and pathophysiology of Parkinson's dementia, dementia with Lewy bodies and their overlap. Associated psychiatric and imaging findings are also considered. Lastly, current and emerging approaches to assessment and treatment in patients with these Lewy body associated dementi

Résumé :
In vivo functional brain imaging provides an opportunity to quantify and localize functional deficits associated with Alzheimer's disease (AD), in relation to dementia severity and heterogeneous cognitive profiles. Such imaging also provides a basis for distinguishing AD from other causes of dementia and for making an early diagnosis of disease. One imaging modality that can elucidate AD is positron emission tomography (PET), which is used to measure regional cerebral metabolic rates for glucose (rCMRglc) and regional cerebral blood flow (rCBF).

Résumé :
In the last decade, the differential diagnosis of dementia has become very challenging. Different clinical syndromes can in fact be associated with the same underlying pathology and different pathologies can be associated with the same clinical phenotype, making it very difficult to distinguish them in vivo. In the present project we focused on the differential diagnosis of cognitive syndromes affecting, at onset, posterior cerebral networks with particular reference to PCA, CBD and LBD, respectively.

In this regard, PD and MSA are defined as synucleinopathies due to the presence of synuclein aggregates; while PSP that is characterized by tau protein accumulations, is part of tauopathies.

Résumé :
The objectives were to explore cognitive function in older adults with Type 2 Diabetes Mellitus (T2DM) through two studies: 1) a pilot study involving the metabolic stress of glucose ingestion and the environmental stress of a functional magnetic resonance imaging (fMRI) environment and 2) an fMRI study exploring the neural mechanisms through hippocampal and prefrontal functional imaging during memory and executive functioning tasks. In T2DM subjects, environmental stress produced greater impairment in memory performance and metabolic stress produced overestimation of memory performance, with

Résumé :
Abstract Dementia syndromes in older adults can be secondary to a wide variety of causes (e.g. infections, exposure to toxic substances, medications, avitaminosis, head trauma, cerebrovascular disease, tumors, or neurodegenerative disorders). However, the most frequent cause is Alzheimer’s disease (AD), which has been reported in up to 10% of the population age 65 or older (Jorm and Jolley 1998). Therefore, there is a significant effort to develop medications that can treat or ameliorate AD symptoms. All suspected known mechanisms of the metabolic cascade of AD have been explored with specific

Perfusion-SPECT allows registration of regional cerebral blood flow (rCBF) which is altered in a characteristic temporal-parietal pattern in AD. Numerous studies have shown the diagnostic value of reduced CBF and metabolic changes using perfusion-SPECT and FDG-PET in AD diagnosis as well as in differential diagnosis against frontotemporal dementia (FTD), dementia with Lewy-Bodies (DLB), and vascular cognitive disorders.

Résumé :
Introduction: In the study of neurodegenerative diseases, Alzheimer’s disease (AD) has been classically considered with a typical presentation of cognitive symptoms and neuroanatomical changes. However, there are clinical phenotypes of AD whose neurobiological bases are similar to frontotemporal dementia (FTD). In this sense, the heterogeneity of these pictures leads to inaccurate evaluation and diagnosis processes, due to the scant knowledge about their neurocognitive symptoms. The early stages of Alzheimer’s-type dementia are classically characterized by memory impairment, whereas behavioral
