VDRL testing can be performed on blood or spinal fluid. Treponemal antibody tests detect antibodies produced by the body only after infection with the bacteria that causes syphilis. This type of antibody is detectable in the body earlier than nontreponemal antibodies and typically remains indefinitely...
Participants were categorized as having MCI if they performed worse than −1.5 s.d. in any cognitive domain according to age and education stratified test norms, as previously described58. AD dementia was diagnosed if the individual was Aβ positive by PET or CSF and met the Diagnostic ...
Affirmative tests for syphilis serology for all cases were performed every two weeks. On follow-up, the expected range (95% CI) for seroconversion was between 9.25 and 10.49 weeks. Most cases (25 cases) completely returned to the VDRL non-reactive stage within 10 weeks; three cases completely...
Groupperformed significantly worse than grouppatients—especially on Stroop tests—but showed post﹕urgery improvement on only the Stroop colour‐naming test. Conclusions The 4 neuropsychological tests of the EU﹊NPH﹕cale can help predict iNPH comorbidities and evaluate the prognosis of CSF shunting....
Tap test Tap tests were performed with the paramedian punc- ture technique, using a 19-gauge spinal tap needle to collect 30 ml of CSF [7]. The gait was assessed using the Timed Up and Go Test (TUG) before and on the 1st, 3rd, and 7th days after the spinal tap. This test was ...
Plasma and CSF Procedures Blood samples were collected at the same time as CSF samples, and the collection was performed in the morning with participants not fasting. Blood samples were collected and analyzed according to a standardized protocol. For each study participant, blood was collected in...
Molecular tests: detection of a specific fungus with a molecular test indicates a likely infection with that fungus if the test was performed on a sample from a sterile body site, such as blood, CSF or tissue. Is there anything else I should know? If a fungus that is causing an infecti...
The three layers of protective membranes around the brain and spinal cord are known as meninges. The innermost layer is called the pia mater; the middle layer is called the arachnoid; and the outermost layer is called the dura mat...
