Stroke also referred to as ‘Cardiovascular Accident’, is a type of a medical condition involving brain function disturbance due to lack of blood flow to the brain. There can be a number of causes that lead to a stroke, like blockages and hemorrhages.
This is a high level medical emergency that can be fatal. There is a high risk of a stroke to people of old age, diabetic patients, people who take high cholesterol diet, consumption of alcohol and smoking. Stokes should be taken seriously as it is considered to be the second leading cause of death in the world.
When a person survives a stroke there is always a risk of further repercussions that might include a second stroke, decreased brain functions, temporary loss of dexterity and paralysis. Hence, special care should be given not only in the hospital but at home as well, so we discuss home care tips for stroke patients. Read the rest of this entry »

Sleep deprivation has become a terrifying problem in our on-the-go society, where working more and sleeping less can be seen as a badge of honor. But even nodding off momentarily can have disastrous results, as we saw in graphic news reports of the December Bronx Metro-North train derailment.
“I was in a daze,” engineer William Rockerfeller told investigators about the moments leading up to the crash. “I don’t know what I was thinking about, and the next thing I know, I was hitting the brakes.”
Sleep scientists think Rockerfeller may have slipped into what’s known as microsleep, when parts of the brain are awake and parts just doze off for a few seconds. But his momentary lack of attention before approaching a dangerous curve too fast derailed more than just the train; it also ended the lives of four people, injured more than 70 others, and probably cost Rockerfeller his career.
Short sleep, or getting less than 6 hours when 7-9 hours is recommended, drastically dampens our attentiveness and reaction times, as well as our health overall. While I’ll describe the negative effects of Short sleep, this article is really about the positive benefits of Restorative sleep, and it concludes with an excellent speech on the topic by Arianna Huffington. I hope it motivates you to add a New Years’ resolution — get more sleep. Read the rest of this entry »
This article explores advances in neural engineering research and is based on my interview with Dr. Metin Akay, Founding Chairman of the new Biomedical Engineering Department and the John S. Dunn professor of biomedical engineering at the University of Houston. His discipline unites the fields of engineering, computer science, physics, chemistry, and mathematics with cellular, molecular, cognitive and behavioral neurosciences.
One expected result of these fields converging is to lower health care costs. Another is to extend life, but as Dr. Akay put it, “While it’s very important to live longer, it’s much more important to have quality of life.” Read the rest of this entry »

Two years ago, IBM’s Watson computer shocked the world when it beat two past grand champions on the TV quiz show Jeopardy!
Watson isn’t playing around anymore.
Watson and the technological leaps forward that made it so revolutionary — the ability to understand human speech, make sense of huge amounts of complex information in split seconds, rank answers based on probability, and learn from its mistakes — are being put to work.
In health care, Watson is helping doctors tailor medical treatment to every patient’s situation in a time when the amount of medical information is doubling every five years. Read the rest of this entry »
This article is about the power of the Internet as a learning and research tool, and the role that young, Internet-savvy innovators are playing as they develop the future of healthcare.
Easton, a 17-year old inventor, spoke recently at TEDxMileHigh about his 3D printing & animatronics project and the future of prosthetic & animatronic limbs. He started this work at age 14 and used the Internet to research and learn about electronics & sensor technologies, programming & modeling software, 3D printing & industrial design, and wireless networking. He’s now living in Houston and working at NASA on robotics projects. Read the rest of this entry »
If you are a family caregiver, think about how much time do you spend, and if you’re feeling overwhelmed. Some 65 million unpaid family caregivers look after elderly or disabled loved ones, averaging 20 hours/wk. AARP did a study that put the 2009 annual burden on unpaid family caregivers at $480 billion/year, including lost worker productivity, reduced earning capacity & retirement income, and increases in their own physical & emotional health and related costs. It’s more than the $361B in Medicaid spending and nearly as much as the $509B in Medicare spending.
The infographic below, from Top10OnlineColleges.org, identifies JOB stress as a leading factor in poor health, but so is not getting enough sleep. Of course the two are closely related. After the infographic and listed highlights (for blind people using a screen reader) are related infographics and articles on both Stress and Sleep. Enjoy, but don’t stress out.

The Impact of Mindset on Quality of Life…
and What Healthcare Providers and Patients Can Do About It
by Samantha Rodgers
Many factors impact a person’s quality of life. Often we focus primarily on physical health and, while that certainly plays a role, it’s not the only component impacting life quality. Healthcare providers and researchers have studied the effect of mindset over the past years, and have learned that what a person thinks or believes and how he or she feels emotionally also plays a role in quality of life.
According to a study conducted by the Department of Healthcare Management and Hacettepe University in Turkey, happiness or a lack thereof has a definite impact on the quality of a person’s life as they age. Similar to improving physical health with medical treatments, healthcare providers and their patients are now also working together to improve quality of life by changing thoughts and attitudes, and boosting emotions.

In this amazing feat of engineering, a person’s thoughts are used to navigate a robot, which makes us wonder about other applications in the future.
Using a brain-computer interface developed by University of Minnesota biomedical engineering professor Bin He, several students learned to steer a robotic quadcopter with just their thoughts. As shown in the video, they navigated the craft around a gym, making it turn, rise, dip, and even sail through a ring.
Similar technology may someday allow disabled people to regain speech or mobility lost due to disease or injury. They may be able to control a variety of devices with just their thoughts, including lights, TV remotes, artificial limbs and wheelchairs. The solution is completely noninvasive: brain waves (EEG) are picked up by electrodes in a cap worn on the scalp, not requiring a chip implanted in the brain.
On the first day of CES I attended a Digital Health Summit panel discussion hosted by Arianna Huffington of The Huffington Post. To introduce the discussion, she described Americans’ increase in antidepressants, sleep medications, and stress, and how 75% of healthcare spending is spent on preventable diseases, and 80% of medications are for pain. All of these conditions are preventable through other means, she said.
The panel discussed a perfect storm of multiple trends: (1) stress (and I’d add sleep deprivation) is a killer, (2) our broken & expensive sick care system, and (3) technology & wearable devices that can help us focus on health & wellness. Market researchers note that 30 million wearable devices shipped in 2012, going to 60 million in the next year. In addition, 44 million health apps will be downloaded to smartphones and tablets this year.
