Cardiovascular disease is currently a large killer of many people in the developed world. The brain is often the source of many of these blood flow problems. Being able to accurately detect and measure cerebral blood flow behavior plays an important role in understanding diseases of the brain. Currently brain measurements are done by x-rays, computer tomography or magnetic resonance imaging. However there are many limitation to these types of brain imaging techniques. These imaging techniques only enable doctors to see static images inside a person's head so they are of limited use.
Scientists have recently invented a new type of brain scan. It is powered by 20 different supercomputers that process data at a trillion calculations per second. This new type of brain scan actually generates a real time image of the human brain. In the near future, surgeons will likely be able to carry out a myriad number of brain surgeries with a much greater accuracy. It has been created by several researchers from the University College of London. This scan is called Genius (Grid-enabled neurosurgical imaging using simulation). This new scan essentially takes several different 2-D X-ray shots at a variety of different angles around a 180 degree arc. The supercomputers can then process all of the data that is collected.
This new type of scan has some really interesting properties. It would basically enable doctors to visualize all of the arteries inside a person's brain. This would be beneficial for various brain conditions that deal with altered blood flow such as aneurysms and atherosclerosis. Currently quite a few brain surgeries may result in a patient having a brain haemorrhage (bleeding of the brain). This type of haemmorrhage is extremely dangerous and can often be fatal for the patient. In the past, doctors often had to do many types of brain surgeries blind. Basically they couldn't visualize things in real time like they will be able to with this new scan. The scan will allow the creation of maps of the arrangement of the arteries inside a person's brain. This will enable surgeons to remove clots or other life-threatening conditions.
In the future, this knew brain scan may be coupled with NeuroArm. Neuroarm is actually a surgical robot that can perform neurosurgery inside a brain scanner. Researchers have recently successfully used this Neuroarm to remove a person's brain tumor. So this device could reduce the death rate of neurosurgery.
Scientists expect that the first trial run of "Genius" will occur sometime within the next year. It may go a long way in improving outcome among patients who have to undergo brain surgery. This new type of brain scan will certainly be revolutionary for the treatment of many brain based disorders. It may save the lives of quite a few people who currently have cerebral blood flow problems.
A New Brain Musical
Many publications haven't fully announced this yet, but we have an exciting initiative to report on. On June 10th, the National Brain Health Road Map was announced by the Center for Disease Control and Prevention and the Alzheimer's Association. The objective of the task forece is to maintain or improve the cognitive performance of all adults accross America, helping us all maintain memory, attention, and other important mental faculties.
I want to first share with you the 10 top actions proposed by this report, and then provide a quick glossary to explain the key words that you will hear more and more when discussing brain health.
Top recommendations:
1) To determine how diverse audiences think about cognitive health and its associations with lifestyle factors. This work has all-ready yielded in a phenomenal report on Baby boomers' current opinion of Brain Health and Fitness, that you can find in the website of the MetLife Foundation.
2) To disseminate the latest science to increase public understanding of cognitive health and to dispel common misconceptions. The discovery of lifelong neuroplasticity and neurogenesis (see glossary below) has given us a new positive view upon the human brain - This is still a concept not many know of. "Use it or lose it" and "Use It and Get More of It" needs to reach all people.
3) Help people understand the connection between risk and protective factors and cognitive health. Good lifestyle habits were superbly presented in the MacArthur study of successful aging: good nutrition, mental and physical exercise, stress management and social engagement.
4) Assess the literature on risk factors (vascular risk and physical inactivity) and related interventions for relationships with cognitive health. As Dr. Marilyn S. Albert at John Hopkins points it out: All the things that we know are bad for your heart turn out to be bad for your brain.
5) More scientific tests will be done to establish the impact of reducing vascular risk factors on lowering the risk of brain decline and improving mental function. Recent findings presented at International Conference on Prevention of Dementia are one big step in the right direction.
6) Further, more research will be conducted on other areas potentially affecting cognitive health such as nutrition, mental activity, and social engagement.
7) The last academic focus is on determining the impact of exercise on reducing the risk factors of brain decline and improving memory.
8) The government will develop a population-based surveillance system to measure the public health burden of cognitive impairment in the United States.
9) Launch public policy projects at all levels to promote brain health by engaging government officials.
10) Brain Fitness will be included in Healthy People 2020, a set of health objectives for the nation that will serve as the foundation for state and community public health plans.
This initiative will help people of all ages take more control of our brain health in the same way we care about our nutrition and body health.
Now let's review some of the most relevant concepts in this field. This vocabulary will become familiar to all of us during the next years::
Brain Fitness: the general state of good, sharp, brain and mind, especially as the result of mental and physical exercise and proper nutrition.
Brain Fitness Program: structured set of brain exercises, usually computer-based, designed to train specific brain areas and functions in targeted ways, and measured by brain fitness assessments.
Chronic Stress: ongoing, long-term stress. Continued physiological arousal where stressors block the formation of new neurons and negatively impact the immune system's defenses.
Cognitive training: variety of brain exercises designed to help work out specific "mental muscles". The principle underlying cognitive training is to help improve "core" abilities, such as attention, memory, problem-solving, which many people consider as fixed.
Cognitive Reserve: theory that addresses the fact that individuals vary considerably in the severity of cognitive aging and clinical dementia. Mental stimulation, education and occupational level are believed to be major active components of building a cognitive reserve that can help resist the attacks of mental disease.
fMRI: fMRI is a technique that enables scientists to observe images of changing blood flow in the brain and thereby know what part of the brain is getting activated when. This allows images to be generated that reflect which structures are activated (and how) during performance of different tasks.
Mindfulness-Based Stress Reduction (MBSR): yoga and meditation practices designed to enable effective responses to stress, pain, and illness.
Neurogenesis: the process by which neurons are created all throughout our lives.
Neuroplasticity: the brain's capacity to rewire itself by forming new connections throughout life.
PubMed: very useful tool to search for published studies. "PubMed is a service of the U.S. National Library of Medicine that includes over 16 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s."
Working memory: the ability to keep information current for a short period while using this information. Working memory is used for controlling attention, and deficits in working memory capacity lead to attention problems. Recent research has proven that working memory training is possible and helpful for people with ADD/ ADHD.
Exciting times ahead! We should all be looking forward what science will bring us to help develop and grow gracefully as we age.
