US Presidential Election 2024: Age and mental health have become a major issue in the US presidential race. However, this issue has been in the limelight before between 81-year-old President Joe Biden and his rival 78-year-old Donald Trump. The issue has reached a decisive turn after Biden's weak performance in the presidential debate last month.

Biden is the oldest president in American history and, if Trump is elected, he will be the second-oldest.

During an interview with ABC News, Biden declined to take a cognitive test. He said he has a cognitive test "every day" and that his doctors say he doesn't need one.

Trump claims he has completed cognitive tests, one while he was president and one more recently. He says he passed both tests.

Do you know what that test is why it is conducted and is it difficult to pass it?

What do cognitive tests reveal?

There are different tests available to measure how well the brain is working. According to the Cleveland Clinic, they do not diagnose a specific disease but help indicate if additional tests are needed for a diagnosis.

Typically, cognitive testing is needed when a person has problems with memory, personality changes, or balance, or is repeating himself, forgetting parts of his past, or having trouble understanding information.

According to Sanford Medicine, one of the most widely used tests is the Montreal Cognitive Assessment (MoCA), which is a quick way to 'assess cognitive skills in people with suspected deficits.'

The assessment checks orientation, memory, attention the ability to name objects, and the ability to follow verbal and written commands. It is also available online.

This is generally easy for a normal person, but difficult for mentally weak people.

The test's creator, Canadian neurologist Ziad Nasreddine, told the BBC he thinks the test could be good for Biden. It could be helpful in reassuring Americans or spotting if he has a problem.

What does a cognitive test consist of?

In a short cognitive test, medical professionals ask patients a series of questions related to learning and memory. A longer clinical evaluation includes cognitive tests as well as a physical and neurological examination and a complete patient history.

Often medical professionals start with a short test like the MoCa, and if their score is lower than expected, they move on to more extensive testing. More intensive testing assesses language, executive function, and visual-spatial abilities.

For example, a medical professional may read a story to a patient and then ask him or her to recall parts of the story to test memory and learning abilities. A patient may be asked to recall a list of words, name objects in pictures, or name objects that begin with a specific letter.

Apart from questioning the patient, experts suggest talking to people who regularly spend time with the patient to detect signs of cognitive decline. According to experts, it is important to see if a person's abilities have changed over time. A one-time assessment can be misleading.
