Recent research on monkeys indicates one brain cell may have the power to restore voluntary movement of paralyzed muscles. Nearly every neuron tested by scientists demonstrated the ability to activate muscles immobilized by drugs in monkeys.
Some suggest that if a monkey can learn how to harness the power of a single neuron to activate muscles that have paralysis, the effect should be even more powerful in humans. This research finding has significant implications for the hundreds of thousands of people with spinal cord injuries annually.
It is thought that some types of spinal cord injuries result in paralysis in which the person is fully conscious inside a body that does not respond to commands. While the brain activity that would normally result in voluntary movement is still present, the directions for such movement do not reach the muscle.
The current research on monkey brain cells suggests a potential therapeutic mechanism by bypassing the type of nerve damage that can result in such paralysis. The brain can learn to control new cells and use them to generate movements quickly. Creating electrical stimulation from new neuronal activation in muscles that are paralyzed represents a future oriented treatment direction for those who suffer paralysis.
When I present my keynote address on Brain Health I try to provide the audience with a glimpse of how complicated and miraculous the human brain really is. I typically make a statement that one day the human brain will be able to fix the maladies of the human body and that one day the human brain will communicate with other brains without opening the mouth.
While this may sound a bit science fiction I believe it to be true. A recent report provides yet more support for where our planet is heading. The automaker Honda has been funding research and development into the ability of the human brain via thoughts to relay commands to a robot that will alter the function of the car. If one wants the air conditioner turned on he or she can complete this by simply thinking the wish and the brain signals will trigger a robot mechanism to make the command happen.
In the near or distant future we will be able to conduct our basic daily functions from mental energies that will enable a much more efficient use of time and energy. It represents a true technological advancement based from the brain. Ultimately, this use of energy will be from brain to brain.
A recent report indicates aspirin and non-steroidal antinflammatory drugs seem to have the positive and perhaps unexpected benefit, of cutting a person’s risk of developing AD.
Researchers at John’s Hopkins reviewed data from 13,499 cases to measure the protective effect from these commonly used drugs on AD risk. Over the course of the studies 820 people developed AD. However, those who used the non-steroidal drugs including aspirin, Ibuprofen (Advil, Motrin and other brands) and Naproxen together had a 23% lower risk for AD than those who did not use such medications.
Researchers stated that while the different types of medications have different properties, they seemed to deliver the same level of protection. This study and others in the past underscore the probable contribution of an inflammatory process related to AD.
This study and the others do not suggest everyone should start taking these medications, but it might be a good topic to discuss with your doctor.
The summer months bring warm weather, blue sky, and plenty of sunshine. For some, if not most, we may notice our mood becomes a bit happier. Is there a relationship between the sunshine and our mood? Probably, but why?
Some studies have reported a relationship between Vitamin D that is derived from sunshine and different physiological measures in the human body. Sunlight has also been related to mood with a disorder known as “Seasonal Affective Disorder” in which those not exposed to enough sunlight can become depressed. Indeed, special lights have been prescribed for those with seasonal affective disorder to help their brains gain more ultraviolet exposure to lift their mood.
Sunshine also tends to come with blue sky, relates to an increased ability to get outside and move about in nature, and to recreate more. Each of these factors is important and is related indirectly to mood enhancement.
It is important to pay attention to your own mood and determine what environmental factors may help you feel happier. If sunshine and blue sky lift your spirits try to prescribe yourself increased time outside. You may feel more energy, higher sense of self and increased productivity.
Recent data indicates Americans are living longer than ever before as life expectancy hit 78.1 years in 2006. Rates for 14 of the top 15 causes of death fell in 2006 according the US Centers for Disease Control and Prevention. The most significant decline in cause of death was attributed to influenza and pneumonia that fell nearly 13% from the previous year.
Life expectancy of 78.1 is up from 77.8 years in 2005 representing a continued rise over the past decades. Women have a life expectancy of 80.7 years while men remain somewhat behind at 75.4 years. Racial disparities also exist with white women’s life expectancy at 81 years compared to 76.9 for black women. White men’s life expectancy was 76 years and black men at 70.
The top two causes of death include heart disease and cancer followed by stroke, chronic lower respiratory diseases such as emphysema and then accidents. Alzheimer’s disease, the most common form of dementia, is now the sixth leading cause of death in the U.S.
Gains made in life expectancy represent an opportunity for continued years of quality of life. Getting started earlier in life with a proactive lifestyle (physical activity, brain fitness, brain games etc.) including that designed for the heart and brain can help to maximize the quality with the increased quantity of life.
