The Aspergillus galactomannan test was performed on cerebrospinal fluid and serum samples from 5 patients with probable cerebral aspergillosis and from 16 control patients. Cerebrospinal fluid galactomannan levels were significantly higher in aspergillosis patients, and most galactomannan was produced intrathecally. Comparison of serum galactomannan values in pulmonary and cerebral aspergillosi...

Synaptic dysfunction is linked to cognitive symptoms in Alzheimer's disease. Thus, measurement of synapse proteins in cerebrospinal fluid may be useful biomarkers to monitor synaptic degeneration. Cerebrospinal fluid levels of the postsynaptic protein neurogranin are increased in Alzheimer's disease, including in the predementia stage of the disease. Here, we tested the performance of cerebrosp...

Reduced cerebrospinal fluid amyloid-β42 and increased retention of florbetapir positron emission tomography are biomarkers reflecting cortical amyloid load in Alzheimer's disease. However, these measurements do not always agree and may represent partly different aspects of the underlying Alzheimer's disease pathology. The goal of this study was therefore to test if cerebrospinal fluid and posit...

Reduced cerebrospinal fluid amyloid-b42 and increased retention of florbetapir positron emission tomography are biomarkers reflecting cortical amyloid load in Alzheimer’s disease. However, these measurements do not always agree and may represent partly different aspects of the underlying Alzheimer’s disease pathology.

Selective brain cooling is a system in a human that protects the brain from hyperthermia. Cool venous blood from head skin and upper respiratory tract drains into intracranial dural sinuses. In that region, cool blood in the dural sinuses decreases the temperature of the cerebrospinal fluid. Cerebrospinal fluid provides brain cooling. All cortical arteries to the brain pass the cerebrospinal fl...
