Assessing the value of MRI for the diagnosis of tauopathies

MRI and tauopathies Progressive supranuclear palsy (PSP) and Corticobasal Degeneration (CBD) are two subtypes of Frontotemporal Lobular Degeneration characterized by cerebral accumulation of tau protein (tauopathies). These diseases present classically with motor symptoms that include postural instability, difficulty in ocular movements, and limb control. However, in recent years it has been shown that they can … Read more

Multimarker synaptic panels for FTD

Multimarker panels in FTD Frontotemporal dementia is the most common cause of early-onset dementia and the principal cause of FrontoTemporal Lobular Degeneration (FTLD). Approximately, 90–95% of FTLD cases are characterized by the accumulation in the brain of two different proteins – tau and transactive response DNA-binding protein-43 (TDP-43). These protein inclusions lead to a loss of … Read more

Stability of Alzheimer biomarkers in CSF

Alzheimer - Sant Pau Memory Unit - Barcelona

Alzheimer’s disease and its biomarkers in CSF Alzheimer’s disease is a chronic neurodegenerative disorder considered the most common cause of dementia in older people. Although clinical symptoms still form the core of diagnosis, imaging and cerebrospinal fluid biomarkers now play an important role in the diagnostic process. Two important neuropathological features of Alzheimer’s are the … Read more

Concordance between amyloid markers in CSF

Delaby Sant Pau Memory Unit - Barcelona

Amyloid peptides and tau markers in CSF Cerebrospinal fluid (CSF) biomarkers of Alzheimer’s disease (AD), such as β-amyloid 1-42 (Aβ1-42), total tau (tTau) and pTau181, have improved the management of patients with cognitive impairment. Although Aβ1-42 is considered a marker of amyloid pathology, a series of studies have shown that a decrease in CSF Aβ1-42 … Read more

GFAP in blood helps predict the evolution of frontotemporal dementia

GFAP and frontotemporal dementia Frontotemporal dementia is a heterogeneous entity with variable clinical manifestations. As a consequence, it can be confused with psychiatric diseases or other neurodegenerative diseases such as Alzheimer’s disease. Despite the advances in the diagnosis of frontotemporal dementia in the last two decades, we still do not have a precise marker for … Read more

New plasma biomarker to detect Alzheimer’s disease in Down syndrome individuals

Down Alzheimer - Plasma Markers - APOE

Plasma biomarkers Scientists worldwide are immersed in the race for accurate, non-invasive and accessible biomarkers to detect and diagnose Alzheimer’s Disease. To date, major scientific advances allowed the identification of several biomarkers in cerebrospinal fluid or using positron emission tomography (PET). Yet, these methods are either invasive or expensive and not easily accessible to all … Read more
