The IDS-TILDA Wave 3 report shows increased rates of health screening, contrasted by increases in chronic health conditions and emerging social isolation issues.
The brain's complex network of neurons enables us to interpret and effortlessly navigate and interact with the world around us. But when these links are damaged due to injury or stroke, critical tasks like perception and movement can be disrupted. New research is helping scientists figure out how to harness the brain's plasticity to rewire these lost connections, an advance that could accelerate the development of neuro-prosthetics.
Houston Methodist is making mini brains from human stem cells, putting researchers on a fast track to repair the nervous system after injury or disease of the brain and spinal cord. Researchers have developed a new system to reduce the time it takes to grow these brain models, which will give them the ability to screen drugs and study what's behind disease-causing mutations more quickly. The findings appear Dec. 12 in Stem Cell Reports.
The first child to undergo a successful hand transplant also is the first child in whom scientists have detected massive changes in how sensations from the hands are represented in the brain. The brain reorganization is thought to have begun six years before the transplant, when the child had both hands amputated because of a severe infection during infancy. Notably, after he received transplanted hands, the patient's brain reverted toward a more typical pattern.
A study led by Indiana University researchers found a previously undetected link between the gene that causes fragile X syndrome and increased tissue growth in the intestines of fruit flies modified to model the disease.
Female Parkinson's disease patients are much less likely than male patients to have caregivers, despite the fact that caregivers report greater strain in caring for male patients. The findings come from a large study reported today in Neurology by researchers at the Perelman School of Medicine at the University of Pennsylvania. According to the researchers, the disparity between female and male patients probably derives in part from the fact that women tend to outlive their most likely potential caregivers: their husbands.
Researchers using CT scans and 3-D printing have created accurate, custom-designed prosthetic replacements for damaged parts of the middle ear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA). The technique has the potential to improve a surgical procedure that often fails because of incorrectly sized prosthetic implants, researchers said.
High-tech prosthetics allow amputees to engage more fully in everyday life, even to compete in sporting events. Researchers from the University of Houston have demonstrated how brain activity is used to identify different terrains -- level ground and stairs, for example -- a key step in developing prosthetics that allow the user's prosthesis to automatically adjust to changing ground conditions in real time.
A new Tel Aviv University study suggests that a therapy that combines Virtual Reality and treadmill exercise dramatically lowers the incidence of falling among Parkinson's patients by changing the brain's behavior and promoting beneficial brain plasticity, even in patients with neurodegenerative disease.
Buttock augmentation is one of the fastest growing aesthetic procedures in the United States. According to the American Society for Aesthetic Plastic Surgery (ASAPS), more than 20,000 procedures were performed in 2016 alone, (a 3,267% increase compared to 2002, when ASAPS first began tracking statistics for buttock augmentation). ASAPS began tracking fat grafting to the buttocks in 2015, and for the two years it has collected that data, an average of 91% of all buttock augmentation procedures have consisted of fat grafting. Recently, The Aesthetic Surgery Education and Research Foundation (ASERF) formed the Gluteal Fat Grafting Task Force to investigate the risks associated with this increasingly popular procedure.
