During the last two decades, neuropathological examination of the brain has evolved both technically and scientifically. The increasing use of immunohistochemistry to detect protein aggregates paralleled a better understanding of neuroanatomical progression of protein deposition. As a consequence, an international effort was achieved to standardize hyperphosphorylated-Tau (phospho-TAU), ßAmyloid (Aß), alpha syncuclein (alpha-syn), phosphorylated transactive response DNA-binding protein 43 (phospho-TDP43) and vascular pathology detection. Meanwhile harmonized staging systems emerged in order to increase inter rater reproducibility. Therefore, a refined definition of Alzheimer's disease was recommended., a clearer picture of the neuropathological lesions diversity emerged secondarily to the systematic assessment of concomitant pathology highlighting finally a low rate of pure AD pathology.. This brings new challenges to laboratory medicine in the field of cerebrospinal fluid (CSF) markers of Alzheimer's disease: how to further validate total Tau, phospho-TAU, Aß40 and Aß42 and new marker level cut-offs while autopsy rates are declining?

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 neurodegenera...
Due to its protected anatomical location, cerebrospinal fluid (CSF) is a very stable fluid which undergoes comparatively little change in the early post-mortem phase. While many immunohistochemical ma...
Chronic immune activation in the blood and central nervous system are consequences of HIV infection that contribute to disease morbidity, and can occur despite virally-suppressive antiretroviral thera...
Dementia of Alzheimer's type (AD) is related to decreased survival. It is not clear whether also biological markers of AD are related to mortality. Low levels of amyloid beta-42 (Aβ42) and high level...
Mortality is increased in parkinsonian disorders; moderately in Parkinson's disease (PD) but markedly in atypical parkinsonian disorders (APD), including multiple system atrophy (MSA), progressive sup...
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 ...
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...
The primary goal is to quantify cerebrospinal fluid (CSF) volume, diffusion characteristics and mechanical properties of brain tissue at two states of arousal.
Cerebrospinal fluid is a clear, colorless fluid that circulates in the cranial and spinal subarachnoid spaces, located between the pia and arachnoid matters. It is mainly produced by the c...
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).
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.
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)
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)
Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.

Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
