Question
T/F: Examining brain tissue from a deceased individual is crucial for a definitive diagnosis of chronic traumatic encephalopathy (CTE)?
T/F: If tau is detected in the cerebrospinal fluid (csf) of a patient, the patient is diagnosed with chronic traumatic encephalopathy (CTE).
One technique that may allow scientists to find tau in living brain tissue of a living person is positron emission tomography (PET). Accurate radiotracers are needed in order for this technique to work well. What would be a characteristic of a good radiotracer for detecting chronic traumatic encephalopathy (CTE)? Select ALL that apply.
compound binds specifically to tau tangles
compound binds to microtubules of axons
compound does not emit positrons
compound can be easily taken up neuronal tissues
compound is not toxic to healthy cells
A.compound binds specifically to tau tangles
B.compound binds to microtubules of axons
C.compound does not emit positrons
D.compound can be easily taken up neuronal tissues
E.compound is not toxic to healthy cells
Explanation / Answer
.:- True .. Because there's no diagnosis for CTE .. Only known method is diagnosing the tissue after the death .
2:- False :- If tau is detected in CSF, it indicates Alzhemer's disease.
3:- Option A:- Bcoz scientist study the moving path of radio tracers in the brain which eventually binds up with tau.
