I was very proud of myself recently when I generated enough determination to quit my perceived addiction to caffeine in the form of coffee. While it is true that I only consumed one cup of coffee in the morning to get my jump on the day, it is also true that my brain demanded that one cup. I know this because when I stopped or missed my cup of coffee I felt a bit sluggish and then the headaches set in if I did not get the fix for several days. We refer to this as an addiction, though some do not like to hear that word to describe their (my) behavior.
After nearly one month of not consuming any coffee and getting through the withdrawal symptoms, I pick up a new research discovery in the Journal of Neuroinflammation (volume 6, 2008) that reports caffeine blocks disruption of blood brain barrier in a rabbit model of Alzheimer’s disease. It seems caffeine consumed in the equivalent of one cup of coffee daily protects against high cholesterol diet induced increases in disruptions of the blood brain barrier, and caffeine might be useful in the treatment of Alzheimer’s.
If high levels of serum cholesterol and disruption of the blood brain barrier are indeed underlying mechanisms in the pathogenesis of Alzheimer’s it suggests I need to reconsider starting my habit again!
The important message in the story is that we continue to monitor the new findings of lifestyle and brain health and change our behavior accordingly. This should not occur in an impulsive way. Rather, the negative effects need to be weighed against the positive effects of particular behaviors. For me, I think I will restart my consumption of coffee, but keep it to ½ cup a day. Moderation is typically a great idea. In the meantime, I will keep an eye out for replication of this finding on the relationship between caffeine and protection against Alzheimer’s.
Stroke is a clinical term that describes cell death in the brain. Stroke is a permanent and can result in significant functional impairment and even death. There are two types of strokes. The first is the most common and is referred to as ischemia. Nearly 80% of all strokes are ischemic and involves a blockage of blood flow that results in cell death. The other 20% of strokes are hemorrhagic that involves a bleeding outward from a weakened artery wall. As the blood gathers increased pressure can be placed on the surrounding brain tissue causing additional damage to the brain.
Both types of stroke are dangerous and can result in deficits of language, attention, information processing speed, and motor skills. Risk factors for stroke include advanced age, high blood pressure, diabetes, obesity, smoking, and poor diet. Typical preventative measures for stroke include the same protocol as used for the healthy heart. We have learned relatively recently how important blood flow to the brain is, particularly when we recognize that the brain commands 25% of the blood from every heart beat.
As part of our ongoing discussion on brain fitness (e.g. brain games) and health lifestyle I have proposed, it is now time to consider the fattiest part of you……your brain.
Your brain, the most miraculous system ever designed in the history of the universe, weighs between two and four pounds and is made up of 60% fat. As a system of your body, it is indeed your fattiest. It is important to understand the role of the fat and how you may keep the fat nice and robust.
One role for the fat in your brain is to insulate neural tracks of cells to propel the electrical impulse carrying information in a rapid way. Without the fat, the brain cells are not insulated and information processing will slow. Many of us complain about how slow our computer is; imagine how tough it must be to suffer a slowing of our own information processing speed.
Research suggests Omega 3 fatty acids are a good source to build or maintain the healthy fat in our system and brain. Indeed, research suggests consumption of Omega 3s can help to fight off dementia. Foods rich in Omega 3s include fish such as salmon, herring, tuna, and sardines. Unsalted nuts such as walnuts are also rich in Omega 3s. It is suggested that we increase our fish intake to several ounces several times a week.
Another important brain boosting food includes fruits and vegetables because they are rich in antioxidants. Antioxidants help to rid the body of oxygen based toxins known as free radicals thought to create breakdown in muscle and tissue. At least one national governing body indicates we should consume five servings of fruits and vegetables a day.
For the New Year consider increasing your intake of fish, fruits and vegetables. Your brain deserves it!
As we enter a new year, I like to reflect on the past year and what that means for the one ahead. It’s been five years that I have been developing the brain fitness market, and have seen a lot of changes – both positive and negative. When I first started, there was minimal interest in the concept of exercising your brain. In the last two years however, there has been an explosion in interest from adults of all ages and media coverage and I have been interviewed by leading publications such as the Wall Street Journal, NY Times, Women’s Health.
This has been great news for both the industry and the general public. We are witnessing a shift in society, and a general awareness about the importance of brain fitness. We saw a similar shift in the 1980s with the physical fitness movement. Researchers and the medical profession pushed the positive health benefits of physical activity, but it took a while for society to fully integrate physical exercise into daily life. Thanks to recent scientific research we now know that the brain is malleable and we can build brain connections at any age. Just ten years ago, this was not thought possible.
Nintendo has also helped open up the brain game market with their extremely successful Brain Age game. This has, of course, created numerous copycats and flooded the consumer market with one-off and weak products. Yet, I am thankful to Nintendo as they were able to bring awareness of brain games to the general public. They had seen the success of their game in Japan and realized there was an aging population worldwide. In addition, they had the resources to market Brain Age and tap into this underserved area. Many people in the scientific and brain fitness community scoff at their game, finding it scientifically weak and a disservice to the consumer. I would have to agree that their product is scientifically weak and I have many of my own complaints. However, Nintendo has hit on something that I understand. They implemented the concepts of “engagement” and “fun factor” and it is one of the main reasons for their success.
So, what does this mean for 2008 and the next five years? There are those who say that the brain fitness market is becoming saturated and is in its later stages. I have seen the market develop up until now, and couldn’t disagree more. Brain fitness is still in its infancy and will see real growth in the next five years. Awareness about brain fitness has now passed the tipping point but we are still falling short in the area of “adoption” into our daily lives. The companies that truly understand what individuals are looking for will be rewarded with enduring customer loyalty. For us at Fit Brains, we believe the “adoption” of brain fitness will be answered through “relevancy”, “motivation” and a “fun factor”. Yes, it is possible to have fun and be scientific too – it just hasn’t been done! Some doctors and people might argue this, but it’s the key to full integration into daily life. People don’t stick with things they don’t enjoy, especially things like long-term health goals that are often difficult to maintain. If we can make an important aspect of a daily routine more accessible and engaging, people will be more likely to do them.
The team here at Fit Brains is extremely excited about 2008! We plan to have our first launch very shortly. Fit Brains will provide a brain games, tools and features that is fun and engaging. We hope people of all ages adopt a brain fitness routine so that we can keep our most important asset strong and healthy!
I have proposed a five factor brain health lifestyle to include (1) Mental Stimulation (e.g. brain games), (2) Physical Activity, (3) Socialization, (4) Nutrition, and (5) Spirituality. For this blog I want to provide some information on the power of socialization.
Research teaches us that social isolation and segregation, particularly in the later years of life is related to increased risk of dementia. Dementia is a general clinical term that describes a decline in general intelligence, loss of memory, language or visuospatial deficit, change in personality, and decline in functional ability. Alzheimer’s Disease (AD) is the number one cause of dementia in the United States.
Other research indicates passivity in the forties is related to increased risk of dementia in later life. There is a relatively strong message to remain integrated and involved in something meaningful across your entire lifespan. It is also important to be engaged with other people and to develop strong relationships. A study this year taught us that loneliness actually increases the risk of dementia. It is not simply being with others, one needs to feel included and related to the group.
It is never too late to develop a personal inventory of your social network and relationships. Assess your life and determine if you are spending time doing the things that inspire you, more importantly that might inspire others. Socialization and all that is discussed in this blog is a brain health issue and one that should be taken seriously.
Our last blog on brain health discussed the importance of mental stimulation (e.g. brain fitness, brain games) as one factor in my five factor brain health lifestyle. Clearly FitBrains provides a fun and healthy brain fitness regiment that is considered mentally stimulating.
Similar to mental stimulation (e.g. brain games), your brain appreciates it when you are physically active. The reason is simple: every time your heart beats 25% of the blood output from that one heartbeat goes directly to your brain! I refer to this as “market share.” If your brain goes even several minutes without sufficient blood and the oxygen carried by the blood will suffer potential damage with functional and cognitive loss.
Research highlights specific physical activities that reduce the risk of dementia (promote brain health). These include:
- Walking on a daily basis
- Aerobic exercise three times a week
- Treadmill, Stepmaster, Stationary bike exercises
- Write with the non-dominant hand daily
Interestingly these activities employ both sides of the body, thereby stimulating both sides of the brain. An ambidextrous brain is probably a more adaptive brain than one that is highly specialized in one hemisphere.
Remember, the more active you are the more your brain will be nourished with the blood-glucose and oxygen it demands. You will have a happy brain!
By now you are well aware of the importance and power of “brain reserve,” the buildup of protective neuronal connections across the lifespan. Brain reserve is one outcome of brain health and is believed to be able to delay the onset of neurodegenerative disease such as Alzheimer’s Disease (AD). I have proposed a five factor brain health lifestyle that includes Socialization, Physical Activity, Mental Stimulation, Nutrition, and Spirituality. Each of these major factors is critical to the health of everyone. As an integrated and proactive lifestyle, the activities and behaviors within each factor can help to shape a healthy brain, beyond what is generated from a passive brain.Mental Stimulation (e.g. brain fitness) is one of the major brain health lifestyle factors. Most people think of the brain as a cognitive or thinking system. While this is certainly true, your brain is far more than simply a thinking system. Your brain is responsible for your emotions, movement, sense of well being, imagination, creative and artistic side and so much more. The brain as a thinking system is certainly well accepted and deservingly so.Research has underscored particular activities that reduce the risk of dementia (brain healthy) and fit well into the mental stimulation slice of my brain health lifestyle. These include:
- Fit Brains brain games
- Reading and writing
- Learning a second language
- Sign Language
- Board Game Playing
- Computerized Brain Exercises
- Musical instrument playing
Obviously, FitBrains provides an important tool and resource for you to stimulate your brain on an ongoing basis. The key element to making mental stimulation a brain health activity is to engage in the “novel and complex.” (e.g. brain games) Tasks that represent the novel and complex for you probably will stimulate your cortex and lead to the development of new neural connections. This is what leads to the buildup of brain reserve. In this scenario, brain fitness using activities such as FitBrains can be considered a health promoting activity, and one that should be included in a proactive brain health lifestyle.
