Can untreated high blood pressure increase your risk of Alzheimer’s disease later in life? Yes. Absolutely.

Untreated high blood pressure throughout life damages your brain by causing “hardening of your blood vessels” and increasing the number of abnormal #Alzheimer’s plaques; and that is why you will be more likely to become demented in your 80s.

Could wearing a tight neck tie reduce blood flow to your brain and cause hypertension? Yes. Absolutely.

New research shows that wearing a tight neck tie can reduce blood flow to the brain by 7.5%. This is significant and can contribute to high blood pressure. 

If you are a man that has to wear neck ties every day, please check your blood pressure. If you do have high blood pressure every day, then consider wearing loose ties or to say goodbye to your ties.

Does our brain go through a remodeling during teenage years? Yes. Absolutely.

Our brain keeps making new cells and remodel pathways for balance, memory, and emotional control during early childhood. The last set of pruning, updating, and renovation of these neuronal pathways happen during teenage years. These substantial changes in the brain structure account for why teenagers may experience turmoil in their behavior and do things that don’t always make sense. Once these changes our completed, our brains are in top notch condition in our 20s. Beyond that, our brain maintains its ability for plasticity and repair; it changes for better or for worse, but not to the same degree that happens in our teenage years. 

Given that anatomical changes happen to the brains of teenagers, we (as parents) need to be patient with them. We need to allow them to find their new pathways in life and guide them to make good decisions. Also, we need to help them eat well, sleep well, and exercise a lot. And of course, we should help them avoid concussions or drug abuse.

Our brains go through major remodeling during our teenagers.

Knowing the brain trauma associated with professional hockey, would I let my kids play it? No. Absolutely not.

A couple of minor bangs to your head would not cause long term neurological tragedies. But banging your head thousands of times during a career in professional hockey (or professional football) sure cause tragic damage to the brain. In my practice, I have seen several retired players with dementia. They have a hard time driving, keeping track of their medications, or figuring out a tip in a restaurant (and they are in their 60s). 

People who choose to engage in sports with high risk of brain damage (such as boxing, hockey, or football) need more education about the long term consequences they will face. Would you like to be demented or have behavioral problems (such as anger management) that shatter your life in your 60s?

It is about time that folks who make millions off the brains of young players acknowledge the link between concussions and dementia in late life, and to do something to remedy the situation.

Is the simplistic concept that too much amyloid causes late-life Alzheimer’s correct? No. Absolutely not.

In 1960’s some researchers proposed the hypothesis that too much accumulation of a protein called Amyloid can cause shrinkage in the brain which then leads to dementia (called Amyloid Cascade Hypothesis).  Initially, it looked like we were finally going to cure Alzheimer’s disease once and for all. But more and more research failed to show that amyloid plaques “cause” brain shrinkage. Pharmaceutical companies spent billions of dollars on finding drugs that reduce levels of amyloid in the brain. They were successful in doing this, but the patients who took the drug did not improve. Many pharmaceutical companies finally realized that amyloid may not be the key target for prevention or treatment of Alzheimer’s disease, but the research community in this field keeps pushing the cascade hypothesis. 

I think Amyloid is likely a marker for damage to the brain, more so than being the culprit itself; it is the smoke, not the fire. Lack of sleep, concussion, and vascular risk factors have all been associated with too much amyloid in the brain. We need to focus on factors that have been shown to improve brain health, such as exercise, diet, and quality sleep for ways we can prevent late-life cognitive decline.

Can too much alcohol prime your brain for getting Alzheimer’s disease? Yes. Absolutely.

Too much alcohol can shrink your brain. It can also impair your brain’s ability to clear the accumulation of toxic Alzheimer’s protein called amyloid, which will put you at risk for becoming demented.

Drinking one or two glasses of alcoholic beverages (maximum of one per day for women and two per day for men) can have some anti-inflammatory benefits for the brain and the heart. You should only consider drinking 1-2 glasses daily if you already exercise at least 45 minutes 4 times a week, sleep well 8 hours a night, have a low stress lifestyle, and keep challenging your brain on a daily basis. If you are not doing these things, then you should limit your drinking to social occasions on weekends only. 

If already have memory problems, you should not drink even one drop of alcohol. It will expedite the rate of your memory loss with aging.

Is there a link between frequent violent hits in hockey and risk of dementia late in life? Yes. Absolutely.

To say there is no link between severe concussions in hockey and risk of #dementia late in life (#CTE) is like saying there is no link between smoking and lung cancer. We need new rules to stop the violent hits in hockey.  Thousands of hit to the brain, in any sport, can lead to dementia later in life. I respectfully disagree with the NHL commissioner, Mr. Bettman.

Can catching up with sleep during weekends help you live longer? Yes. Absolutely.

Your body and brain keep  track of how many hours of sleep you have missed during the week.  This “sleep deficit” adds up over time and can lead to a wide range of brain problems such as Alzheimer’s disease, depression, and fatigue. Catching up with sleep during weekends is an excellent way to pay your “deficit” and stay healthy. By doing so, you will also live longer.
