    Mini Strokes Can Cause Brain Damage, Lead To Dementia And Cognitive Impairment: Study

    Chances are if you're a senior managing your health, you've already had a conversation with your doctor about stroke risk. While many patients know the warning signs of stroke -- slurred speech, weakness on one side of the body, coordination problems, double vision, and headaches -- health care providers often fail to educate patients about their risk for silent or mini-strokes, which can cause progressive, permanent damage and lead to dementia.

    A new study published in the Journal of Neuroscience, examined the effects of these so-called mini-strokes. They frequently are not diagnosed or detected by a doctor because a patient does not immediately present with stroke signs. Mini-strokes may lead to permanent neurological damage and increase risk for full blown stroke.

    Maiken Nedergaard, MD, lead author of the study and professor of neurosurgery at the University of Rochester Medical Center, says at least half of individuals over the age of 60 will experience one mini-stroke in their lifetime. She calls the prevalence of mini-strokes "an epidemic."

    Study Details Brain Damage Triggered by Mini-Strokes

    A new study appearing today in the Journal of Neuroscience details for the first time how "mini-strokes" cause prolonged periods of brain damage and result in cognitive impairment. These strokes, which are often imperceptible, are common in older adults and are believed to contribute to dementia.

    "Our research indicates that neurons are being lost as a result of delayed processes following a mini-strokes that may differ fundamentally from those of acute ischemic events," said Maiken Nedergaard, M.D., D.M.Sc., the lead author of the study and professor of Neurosurgery at the University of Rochester Medical Center. "This observation suggests that the therapeutic window to protect cells after these tiny strokes may extend to days and weeks after the initial injury."

    Scientists Create Endless Supply of Myelin-Forming Cells

    In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potential human stem cell therapies; ensuring that an abundant supply of cells is available to study and ultimately treat people with diseases.

    One of the major factors that will determine the viability of stem cell therapies is access to a safe and reliable supply of cells, said University of Rochester Medical Center (URMC) neurologist Steve Goldman, M.D., Ph.D., lead author of the study. This study demonstrates that – in the case of certain populations of brain cells – we now understand the cell biology and the mechanisms necessary to control cell division and generate an almost endless supply of cells.

    Scientists Discover Previously Unknown Cleansing System in Brain

    A previously unrecognized system that drains waste from the brain at a rapid clip has been discovered by neuroscientists at the University of Rochester Medical Center. The findings were published online August 15 in Science Translational Medicine.

    The highly organized system acts like a series of pipes that piggyback on the brain's blood vessels, sort of a shadow plumbing system that seems to serve much the same function in the brain as the lymph system does in the rest of the body – to drain away waste products.

    “Waste clearance is of central importance to every organ, and there have been long-standing questions about how the brain gets rid of its waste,” said Maiken Nedergaard, M.D., D.M.Sc., senior author of the paper and co-director of the University's Center for Translational Neuromedicine. “This work shows that the brain is cleansing itself in a more organized way and on a much larger scale than has been realized previously.

    We're hopeful that these findings have implications for many conditions that involve the brain, such as traumatic brain injury, Alzheimer's disease, stroke, and Parkinson's disease, she added.

    Funding Awarded to Senior Design Project

    The UR Technology Development fund has decided to invest approximately $50,000 toward the development of a product designed by a Senior Design Team in Biomedical Engineering. Benjamin Horowitz, Megan Makarski, William Sipprell, and Robert Handzel (Biomedical Engineering, '09), working with Strong Neonatologists Timothy Stevens, M.D., and Patricia Chess, M.D., designed and prototyped a respiration monitor for use on very low birth weight newborns. With this funding, which was awarded to Scott Seidman, Ph.D., Associate Professor of Biomedical Engineering and Neurobiology & Anantomy, a second-generation prototype ready for introduction into the Neonatal Intensive Care Unit will be constructed and tested, with the clear aim of getting this life-saving technology onto the market.

    Once Considered Mainly ‘Brain Glue,’ Astrocytes’ Power Revealed

    A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier cells known as neurons, wields more power in the brain than has been realized, according to new research published today in Science Signaling.

    Neuroscientists at the University of Rochester Medical Center report that astrocytes are crucial for creating the proper environment for our brains to work. The team found that the cells play a key role in reducing or stopping the electrical signals that are considered brain activity, playing an active role in determining when cells called neurons fire and when they don't.

    That is a big step forward from what scientists have long considered the role of astrocytes – to nurture neurons and keep them healthy.

    Astrocytes have long been called housekeeping cells – tending to neurons, nurturing them, and cleaning up after them, said Maiken Nedergaard, M.D., D.M.Sc., professor of Neurosurgery and leader of the study. "It turns out that they can influence the actions of neurons in ways that have not been realized."

    Each Flick of a Digit Is a Job for All 5

    You may think you're pretty familiar with your hands. You may think you know them like the back of your hand. But as the following exercises derived from the latest hand research will reveal, your pair of bioengineering sensations still hold quite a few surprises up their sleeve.

    Our fingers can seem like restless Ariels, so fast and dexterous you'd think they had plans and options of their own. Yet as scientists who study the performance, circuitry and evolution of the human hand have lately determined, the appearance of digital independence is deeply deceptive.

    Even when you think you're moving just one finger, said Marc H. Schieber, a professor of neurology and neurobiology at the University of Rochester Medical Center, you're really controlling your entire hand. The pianist playing Ravel or the typist clacking on Blogspot? People tend to think, they're hitting one key at a time, so they must be moving one finger at a time to hit that key, Dr. Schieber said. But really, all the fingers are in motion all the time.
