Background: Neuropsychological tests, including tests of language ability, are frequently used to differentiate normal from pathological cognitive aging. However, language can be particularly difficult to assess in a standardized manner in cross-cultural studies and in patients from different educational and cultural backgrounds. This study examined the effects of age, gender, education and race on performance […]
Diagnostic performance of cerebrospinal fluid total tau and phosphorylated tau in Creutzfeldt-Jakob disease: results from the Swedish Mortality Registry

Importance: Identifying a clinical distinction between the invariably lethal prion disease Creutzfeldt-Jakob disease (CJD) and nonprion rapidly progressive dementias is important and sometimes difficult; thus, reliable tools for diagnosis are in great demand.; Objective: To test the diagnostic performance of dementia cerebrospinal fluid (CSF) biomarkers total tau (T-tau), phosphorylated tau (P-tau), and the T-tau to […]
Alzheimer’s disease (AD) and executive dysfunction. A case-control study on the significance of frontal white matter changes detected by diffusion tensor imaging (DTI)

Englund, Elisabet,
Passant, Ulla
White matter (WM) changes are frequently seen on structural imaging in AD but the clinical relevance of these changes is uncertain. Frontal WM pathology is often observed upon neuropathological examination in AD. Since frontal cortical/sub-cortical pathology is known to relate to executive dysfunction, the aim was to elucidate if frontal WM changes in AD correlated […]

Objective: To determine the prevalence of cognitive complaints and HIV-associated neurocognitive disorders (HANDs) in a cohort of aviremic HIV-positive patients. To evaluate the relevance of the HIV dementia scale to detect HANDs.; Design: Assessment of HANDs with neuropsychological tests.; Methods: Two hundred HIV-infected patients with undetectable HIV-1 RNA concentrations in the plasma, no history of […]
Longitudinal progression of cognitive decline correlates with changes in the spatial pattern of brain 18F-FDG PET

Claassen, D.,
Kang, H.,
Ding, Z.,
Rogers, B.,
Mishra, A.,
Riddle, W. R.
Unlabelled: Evaluating the symptomatic progression of mild cognitive impairment (MCI) caused by Alzheimer disease (AD) is practically accomplished by tracking performance on cognitive tasks, such as the Alzheimer Disease Assessment Scale’s cognitive subscale (ADAS_cog), the Mini-Mental Status Examination (MMSE), and the Functional Activities Questionnaire (FAQ). The longitudinal relationships between cognitive decline and metabolic function as […]

The close correlation between abnormally low pre-mortem cerebrospinal fluid (CSF) concentrations of amyloid-β1-42 (Aβ(1-42)) and plaque burden measured by amyloid imaging as well as between pathologically increased levels of CSF tau and the extent of neurodegeneration measured by MRI has led to growing interest in using these biomarkers to predict the presence of AD plaque […]

Objectives: To evaluate the performance of a one-minute screening test measured against a validated 10-minute screening test for mild cognitive impairment (MCI) in detecting CI in patients aged > or = 65 years with two or more vascular risk factors (VRF).; Methods: Patients (n=1523) aged 65 years or older without documented CI symptoms or dementia […]

Six young related pre-symptomatic carriers of a His163Tyr mutation in the presenilin 1 gene who will develop early onset familial Alzheimer’s disease (eoFAD), and a control group of 23 non-carriers underwent (18)F-fluorodeoxyglucose positron emission tomography (FDG PET). The mutation carriers were followed-up after 2 years. Multivariate analysis showed clear separation of carriers from non-carriers on […]
Additional use of Aβ₄₂/Aβ₄₀ ratio with cerebrospinal fluid biomarkers P-tau and Aβ₄₂ increases the level of evidence of Alzheimer’s disease pathophysiological process in routine practice

Escanyé, Marie-Christine,
Olivier, Jean-Luc,
Malaplate-Armand, Catherine
Background: Cerebrospinal fluid (CSF) biomarkers have recently been included in the criteria for the diagnosis of Alzheimer’s disease (AD). Since interpretation of CSF profile requires the combination of three parameters, biological data are not always conclusive and isolated elevation of phosphorylated tau (P-tau) or reduction of amyloid-β (Aβ)42 alone can be observed. In these cases, […]
