Changes in key biomarkers of Alzheimer's disease during midlife may help identify those who will develop dementia years later. The study found that drops in amyloid beta 42 levels among cognitively normal participants are linked to the appearance of plaques in brain scans years later.
Researchers found a network of lymphatic vessels in the meningeal linings of the brain, directly connected to systemic lymphatic networks. This discovery raises new questions about fundamental brain functions and mechanisms of brain diseases.
A portable ultrasound device has been developed to diagnose bacterial meningitis in babies, replacing painful and time-consuming lumbar punctures. The device uses high-resolution imaging and algorithms to detect cellularity in cerebrospinal fluid, indicating infection within seconds.
A global research team led by Case Western Reserve scientist discovered a genetic dysfunction connected to hydrocephalus, illustrating how one error can contribute to excessive cerebrospinal fluid. The study found that Dvl genes regulate the placement and alignment of cilia in ependymal cells, essential for efficient fluid movement.
A study published in JAMA Neurology found that inosine treatment increases blood and cerebrospinal fluid urate levels in early Parkinson disease patients, suggesting a potential strategy to slow disability progression. The treatment was also shown to be safe and tolerable, with minimal serious adverse events.
Measuring changes in proteins in people with amyotrophic lateral sclerosis (ALS) may better predict disease progression, according to scientists at Penn State College of Medicine. Biomarkers from plasma and cerebrospinal fluid identified as useful in predicting disease duration.
Researchers analyzed cerebrospinal fluid biomarkers in patients with early-stage Parkinson's disease (PD) and healthy controls. Lower levels of Alzheimer's beta-1-42 and tau proteins were found in PD patients, associated with motor severity. The study suggests that these biomarkers have prognostic potential for early-stage PD.
A study found that decreased Aß42 and increased phosphorylated tau181 levels in spinal fluid are linked to reduced default mode network integrity. This association suggests that these biomarkers could be used to detect Alzheimer's disease pathology before symptoms appear.

Research suggests that cerebrospinal fluid biomarkers can identify individuals at high risk for Alzheimer's disease up to 5-10 years before symptoms appear. Studies found reduced Aβ42 and elevated T-tau and P-tau levels in patients with mild cognitive impairment who later developed Alzheimer's.
Researchers identified a signature of three biomarkers in cerebrospinal fluid that can correctly classify patients with Alzheimer's disease. The study suggests that these biomarkers can detect the pathogenic process of Alzheimer's disease at an early stage, potentially leading to earlier diagnosis and treatment.
A new study finds that X-ray-guided spinal tap procedures fail in about 60% of young infant cases and cause bleeding in 25% of infant cases. For patients over 80, the risk of bleeding doubles, but can be reduced by inserting the needle in the middle of the lower back.
Researchers identified a genetic variation associated with an earlier age of onset in Alzheimer's disease, which affects the brain's tau protein levels. The study suggests that these variations lead to higher tau levels in cerebrospinal fluid and earlier cognitive problems once amyloid plaques form.
