Low-flow cerebrospinal fluid in Huntington’s disease: study

Vanderbilt researchers found reduced net flow of cerebrospinal fluid in Huntington’s disease, which could contribute to mutant protein retention and altered responsiveness to medications delivered via the spinal cord.

Neurofluid flow and Alzheimer’s disease

Vanderbilt researchers used novel MRI methods to noninvasively quantify measures of neurofluid circulation and found that hypertrophy of a site of cerebrospinal fluid egress may be related to amyloid-beta retention in Alzheimer’s disease.

Survey identifies factors in reducing clinical research coordinator turnover

Strong, collaborative relationships with principal investigators are a key factor of longevity in clinical research coordinator positions — an essential, but increasingly transient job in executing treatment-advancing clinical trials, Vanderbilt University Medical Center researchers found.
