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.

B.

C.

D.

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.
