Your brain is ageing.
In fact, it began in your early 20s but will only manifest later on, usually in your 40s, and accelerate in your 60s.
“During this gradual decline, you will experience greater difficulty in learning, memory and multi-tasking. To slow this process, it is crucial to maintain a healthy brain and lifestyle,” says Shawn Watson, neuroscientist and chief executive officer of Senescence Life Sciences.
What happens when the brain ages
As you get older, your brain cells slow down. Consequently, they don’t respond as much to stimuli as young brain cells, so the electrical signal sent to other brain cells is weaker. Shawn says the weakened connections impair the storage of new information as well as the recall of information already stashed in your head.
“The popular belief is that our brain cells start dying off as we age. That isn’t true in the case of natural ageing. The death of cells in the brain is only associated with pathological diseases like Alzheimer’s disease,” Shawn points out.
How to stay mentally sharp
While there are several risk factors associated with Alzheimer’s disease or dementia, including smoking, high blood pressure, diabetes and obesity, here’s the good news: “Genes are a very poor predictor of dementia,” says Shawn.
In reality, there is a very low risk of getting Alzheimer’s based on family history alone – even though many people fear inheriting the disease from their parents,
“Your brain health is very closely tied to your body’s health,” says Shawn. “In order to keep your brain in tip-top condition, you should keep your body well too.” Here are some ways.
