Why The South Has A Worst Memory Than The North?

People living in the America South have been known to have a higher chance of having a stroke and to be more likely to die from them than the rest of the U.S. For this reason, you will sometimes find the South be referred as the "stroke belt".

A new large national study in the U.S. has found that people who lived in the Southern states of the country not only had this greater risk of stroke but also a higher chance of cognitive decline than people living in the North over several years. People in the South might face a faster failing memory, slow thought processes and orientation.

Researchers at the University Of Alabama found that people who live in eight southeastern states have a 18% higher risk of developing decline than the rest of the country. The study had about 24,000 participants who where asked to name familiar items in the grocery store or to remember words from  a list that was read earlier.

The researchers believe than a probable reason for this difference is the higher rate of hypertension that can found in the Southern states. It appears to be a link between heart health and brain health as high blood pressure can cause small blood vessel change in the brain. Other reasons for this difference could also be the higher rate of obesity in the South, the fact that people tend to smoke more and that they exercise less which all have a correlation with high blood pressure.

One of the other conclusion that can be drawn from this study is how clearly your brain health also depends of your overall health condition. By exercising, eating correctly and training your brain, you can start improving your brain health and help prevent memory problems that could lead to more serious conditions such as Mild Cognitive Impairment (MCI), dementia or Alzheimer's disease (AD).
