Only those with the sharpest eyesight can spot the incorrect word

There are many different ways to stimulate the mind in a fun and entertaining, but one of the easiest is to do a brainteaser.

The three most common types of brainteasers are observational, analytical, and mathematical. Mathematical brainteasers come in the form of tricky maths-based puzzles whilst analytical brainteasers are intricate word puzzles.

Observational brainteasers, such as the one above by Quizgecko, are often the most common type of brainteaser.

In this brainteaser, the user is faced with row upon row of the word ‘Summer’, but their task is to try and spot the odd word as out as soon as possible.

Did you spot the odd word out? No worries if not, the answer is circled above. The odd word out can be spotted in the third column on the right in the ninth row from the bottom.

Brainteasers like this one are a great way to exercise the mind in the same way running, cycling, or swimming can be used to help the muscles in the arms and legs.

This can sometimes contribute to neurological health and the healthier the mind is, the less likely someone might be to develop a neurological condition such as dementia.

This doesn’t mean that brainteasers can stop someone from developing dementia, but they could help keep someone’s mind sharper for longer.

Dementia is one of the most devastating neurological conditions someone can develop and every year it destroys thousands of lives. However, in recent years new treatments have been developed to fight the disease and diagnose someone sooner so those treatments can be more effective.

Earlier this year, scientists revealed a revolutionary new jab that could remove toxic proteins from the brain had been developed before they became Alzheimer's, the most common form of dementia. If the jab passes clinical trials, experts believe it could be ready for the general public within five years.

Alzheimer’s expert at Cambridge University, Dr Shahid Zaman said: “We finally have something that targets the amyloid protein and clears it. We can be very optimistic this vaccine will prevent or delay the onset of Alzheimer’s.”

Chief executive of AC Immune, the company which developed the vaccine, Dr Andrea Pfeifer, said: “This could absolutely be a game-changer.

“This could ultimately treat a population of hundreds of millions of people who develop this terrible disease which causes so much suffering to patients and their loved ones.”
