Example Question #31 : Defining And Diagnosing Disorders

What age of Alzheimer's diagnosis is considered to be early onset?

Possible Answers:

\(\displaystyle 70\textup{ and younger }\)

None of these

\(\displaystyle 30\textup{s}\)

\(\displaystyle 40\textup{s} \textup { to } 50\textup{s}\)

\(\displaystyle 60\textup{s}\)

Correct answer:

\(\displaystyle 40\textup{s} \textup { to } 50\textup{s}\)

Explanation:

The lines are rather blurry, but cases are considered early onset Alzheimer's when diagnosis occurs in the 40s or 50s. Along with the age of onset, early-onset diagnosis is based on symptomatic criteria. Unfortunately, the only way to determine the exact class of dementia, an autopsy is required to examine brain tissue.
