Midlife changes in Alzheimer's biomarkers may predict dementia

Studying brain scans and cerebrospinal fluid of healthy adults, scientists have shown that changes in key biomarkers of Alzheimer's disease during midlife may help identify those who will develop dementia years later, according ...

Genes linked to Alzheimer's risk, resilience identified

An international team of researchers led by scientists at Washington University School of Medicine in St. Louis has identified a pair of genes that influence risk for both late-onset and early-onset Alzheimer's disease.

Decreased deep sleep linked to early signs of Alzheimer's disease

Poor sleep is a hallmark of Alzheimer's disease. People with the disease tend to wake up tired, and their nights become even less refreshing as memory loss and other symptoms worsen. But how and why restless nights are linked ...

The most important hair on your head is on the inside

Cells along the brain's cavities are equipped with tiny hair-like protrusions called cilia. Cilia are still poorly understood, but we know a few things about what can happen if they are not doing their job.

Cerebrospinal fluid

Cerebrospinal fluid (CSF), Liquor cerebrospinalis, is a clear bodily fluid that occupies the subarachnoid space and the ventricular system around and inside the brain. Essentially, the brain "floats" in it.

More specifically, the CSF occupies the space between the arachnoid mater (the middle layer of the brain cover, meninges) and the pia mater (the layer of the meninges closest to the brain). It constitutes the content of all intra-cerebral (inside the brain, cerebrum) ventricles, cisterns and sulci (singular sulcus), as well as the central canal of the spinal cord.

It acts as a "cushion" or buffer for the cortex, providing a basic mechanical and immunological protection to the brain inside the skull.
