Accumulating data suggest that elevated cerebrospinal fluid (CSF) neurofilament light (NfL) and neurogranin (Ng) levels are associated with cognitive decline and may be useful markers of neurodegeneration. However, to our knowledge, previous studies have not assessed these CSF markers in the community, evaluated them with regards to risk of mild cognitive impairment (MCI), or compared their prognostic value with CSF total tau (T-tau) or phosphorylated tau (P-tau).

The relationship of cerebrospinal fluid (CSF) extracellular vesicles (EVs) to neurocognitive impairment (NCI) in HIV-infected individuals is unclear. Here, we characterize CSF EVs and their associatio...
Neurofilament light (NFL) is a well-validated biomarker for neuronal injury and neurodegeneration. Increased cerebrospinal fluid (CSF) levels have been shown after stroke, as well as in patients with ...
Delirium is associated with new-onset dementia, suggesting that delirium pathophysiology involves neuronal injury. Neurofilament light (NFL) is a sensitive biomarker for neuroaxonal injury.
Cerebrospinal fluid (CSF) markers of neurodegeneration [neurofilament light chain (NFL), total Tau (T-Tau)], tau pathology [phosphorylated tau (p-Tau)], glial cell damage or activation [glial fibrilla...
Central nervous system (CNS) inflammatory demyelinating disease (IDD) is an immune-mediated disease that is pathologically characterized by demyelination and inflammatory infiltration in the CNS and i...
The purpose of this study is to investigate if B vitamin substitution have effect on NFL (neurofilament light protein) plasma levels and neurocognitive performance in HIV-infected individu...
In this project we are collecting cerebrospinal fluid and blood from patients at Vanderbilt Medical Center who have a subarachnoid hemorrhage which has followed the rupture of a brain aneu...
The purpose of this study is: 1. To identify specific set of proteins in the cerebrospinal fluid (fluid surrounding the brain and the spinal cord), that are believed to be seen in ...
Patients with a thoracoabdominal aortic aneurysm in need of an endovascular or open operative restructuring will be asked to participate in this study. After obtaining written consent a ce...
This research will be achieved by the assessment of p75NTR-ECD expression (total and linked to different species of Aβ (Aβ1-40 and Aβ-1-42)) within the cerebrospinal fluid (CSF) of pati...
Discharge of cerebrospinal fluid through a hole through the skull bone most commonly draining from the nose (CEREBROSPINAL FLUID RHINORRHEA) or the ear (CEREBROSPINAL FLUID OTORRHEA).
Proteins in the cerebrospinal fluid, normally albumin and globulin present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. (Brain and Bannister's Clinical Neurology, 7th ed, p221)
Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.
Type III intermediate filament proteins that assemble into neurofilaments, the major cytoskeletal element in nerve axons and dendrites. They consist of three distinct polypeptides, the neurofilament triplet. Types I, II, and IV intermediate filament proteins form other cytoskeletal elements such as keratins and lamins. It appears that the metabolism of neurofilaments is disturbed in Alzheimer's disease, as indicated by the presence of neurofilament epitopes in the neurofibrillary tangles, as well as by the severe reduction of the expression of the gene for the light neurofilament subunit of the neurofilament triplet in brains of Alzheimer's patients.

Discharge of cerebrospinal fluid through the nose. Common etiologies include trauma, neoplasms, and prior surgery, although the condition may occur spontaneously. (Otolaryngol Head Neck Surg 1997 Apr;116(4):442-9)
