Background Alterations in the CSF/serum albumin ratio (Qalb) is currently recognized as
one of the most reliable markers of blood–brain barrier impairment and blood-CSF barrier …

Background: Previous studies have shown an association between disruption of the blood-
brain-barrier (BBB) and dementias of different etiologies. The protein concentration of …

Background The cerebrospinal fluid (CSF)/serum albumin quotient (Q-Alb) is a marker of the
blood-CSF barrier (BCSFB) and possibly of the blood–brain barrier (BBB). The latter is …

Background: Studies have found a disruption of the blood-brain barrier (BBB) in patients
with Alzheimer's disease (AD), but there is little evidence of the changes in the BBB over …

A connection between dementias and blood-brain barrier (BBB) dysfunction has been
suggested, but previous studies have yielded conflicting results. We examined …

Objective: This study investigated whether α-synuclein and tau in cerebrospinal fluid (CSF)
can be used as biomarkers to diagnose dementia with Lewy bodies (DLB). Materials and …

Background Abnormal cerebrospinal fluid (CSF)/serum albumin ratio (Qalb) levels have
been observed in patients with cognitive impairment. Few studies have specifically focused …

Dementia with Lewy Bodies (DLB) is a common form of cognitive neurodegenerative
disease. Only one third of patients are correctly diagnosed due to the clinical similarity …

Background The cerebrospinal fluid (CSF)/serum quotient of albumin (QAlb) is the most
used biomarker for the evaluation of blood–cerebrospinal fluid barrier (B-CSF-B) …

Background: Cerebrospinal-fluid (CSF) Alzheimer's Disease (AD) biomarkers have been
extensively studied in Parkinson's Disease (PD). Although reduced CSF beta-amyloid1-42 …
