The eyes may reveal how experiences are recalled, according to new Baycrest research that suggests that shifts in eye movements play a critical role in memory retrieval. The findings offer new insight into how memory works and how it may change with brain disease. https://medicalxpress.com/news/2026-02-eye-movements-memory-recall.html Mon, 09 Feb 2026 16:54:31 EST news689878442 There is no known cure for Huntington's disease. A genetic mutation creates harmful proteins that accumulate and cause the disease's typical symptoms. A team from the Department of Human Genetics at Ruhr University Bochum, Germany, has now shown how targeted ubiquitin tagging at two positions in the mutated huntingtin protein affects its breakdown and distribution within the cell. This insight could provide a starting point for future therapies. The team in Bochum, led by Professor Hoa Huu Phuc Nguyen, worked closely with Israeli researcher Professor Aaron Ciechanover, who was awarded the Nobel Prize in Chemistry in 2004 for his work on the protein degradation system. https://medicalxpress.com/news/2026-02-huntington-proteins-pile-key-tags.html Sun, 08 Feb 2026 11:00:01 EST news689527367 Parkinson's disease is a progressive neurodegenerative disorder that affects more than one million people in the United States, with approximately 90,000 new cases diagnosed each year. Although available treatments can help manage symptoms, there is currently no cure or therapy proven to slow the progression of the disease. https://medicalxpress.com/news/2026-02-stem-cell-brain-implants-aim.html Thu, 05 Feb 2026 19:10:05 EST news689504624 When you go for a walk, how does your brain know the difference between a parked car and a moving car? This seemingly simple distinction is challenging because eye movements, such as the ones we make when watching a car pass by, make even stationary objects move across the retina—motion that has long been thought of as visual "noise" the brain must subtract out. https://medicalxpress.com/news/2026-02-eye-movements-brain-3d-assumption.html Wed, 04 Feb 2026 17:20:01 EST news689442322 Parkinson's disease, a progressive neurological disorder affecting more than 1 million people in the U.S. and more than 10 million globally, is characterized by debilitating symptoms such as tremors, movement difficulties, sleep disturbances and cognitive impairments. While current treatments, including long-term medication and invasive deep brain stimulation (DBS), can alleviate symptoms, they cannot halt progression or cure the disease. https://medicalxpress.com/news/2026-02-brain-network-responsible-parkinson-disease.html Wed, 04 Feb 2026 11:00:03 EST news689415121 Stroke survivors often face substantial and long-lasting problems with their arms. Both arms often decline together: When one arm is more severely affected by the stroke, the other becomes more difficult to use as well. Compared with a healthy person's dominant hand, a stroke survivor may take up to three times longer to complete everyday tasks using their less-impaired arm. https://medicalxpress.com/news/2026-02-survivors-counterintuitively-recovery-stronger-arm.html Mon, 02 Feb 2026 13:17:35 EST news689260622 Researchers at University of Tsukuba have identified two fundamental coordination patterns underlying the underwater dolphin kick in swimmers: (1) the coordinated motion of the shank and foot and (2) hip flexion and extension centered on thigh movement. They also found that faster swimmers employ a distinctive arm-trunk-thigh coordination strategy, and they maintain a streamlined upper body by adjusting shoulder and lower trunk movements in response to thigh motion. https://medicalxpress.com/news/2026-01-fundamental-patterns-underwater-dolphin.html Thu, 29 Jan 2026 17:50:02 EST news688912460 A breakthrough method from the 1990s is now being transformed into an AI-powered tool to help doctors diagnose cerebral palsy. https://medicalxpress.com/news/2026-01-baby-small-movements-big-consequences.html Wed, 21 Jan 2026 18:10:02 EST news688219447 While some factors that improve or reduce the quality of sleep are relatively well understood, many are not. Given the impact that sleep is known to have on matters such as stress, concentration and cognitive abilities, it is an important topic of study. https://medicalxpress.com/news/2026-01-social-isolation-quality-mice.html Wed, 21 Jan 2026 10:20:06 EST news688212750 Bowel habits aren't exactly dinner-table talk. But they reflect how quickly the gut moves things along, and when that goes wrong, people can experience constipation, diarrhea, or irritable bowel syndrome (IBS). Yet the biological mechanisms that control bowel movements are still not fully understood. https://medicalxpress.com/news/2026-01-unexpected-vitamin-b1-emerges-genetic.html Tue, 20 Jan 2026 09:00:02 EST news688050326 Most people take for granted which hand they use to reach for a cup of coffee or a puzzle piece. However, a new study out of York University suggests that for autistic individuals, which hand they use for various tasks is highly variable, which points to profound differences in the brain. https://medicalxpress.com/news/2026-01-left-dominance-window-autistic-brain.html Mon, 19 Jan 2026 12:45:38 EST news688049101 A University of Queensland food waste researcher says Australia's hospitals and aged care facilities could save money and effort through better tracking of uneaten meals. https://medicalxpress.com/news/2026-01-food-health.html Mon, 19 Jan 2026 08:48:37 EST news688034882 Autistic and non-autistic people express emotions differently through their facial movements, according to a new study, which may help to explain why emotional expressions are sometimes misinterpreted between the two groups. https://medicalxpress.com/news/2026-01-autistic-differ-anger-happiness-sadness.html Mon, 19 Jan 2026 08:13:52 EST news688032747 Talking while driving is widely recognized as a major source of distraction, but the specific ways conversation interferes with the earliest stages of visual processing have remained largely unclear. While previous research has shown that cognitive distraction can slow braking or reduce situational awareness, the question of whether talking disrupts the foundational gaze processes that precede physical reactions has remained unanswered. https://medicalxpress.com/news/2025-12-everyday-conversations-delay-eye-movements.html Mon, 29 Dec 2025 04:58:15 EST news686206663 Injure a tendon and you might not notice right away, but beware: These injuries often fail to heal properly, putting everyday activities at risk. https://medicalxpress.com/news/2025-12-tendon.html Mon, 15 Dec 2025 08:29:20 EST news685009545 Essential tremor (ET) is a common movement disorder affecting about 2% of the American population, and more than 20% of those over 90 years old. Despite its prevalence and decades of study, researchers don't know the precise mechanisms underlying ET. https://medicalxpress.com/news/2025-12-essential-tremor-movement-disorder-linked.html Fri, 05 Dec 2025 07:16:13 EST news684141362 Millions of people struggle with lower back pain worldwide. Now, surprising new research from the University of South Australia shows that relearning 'baby' movements such as crawling, rolling and squatting could help reduce discomfort and rebuild confidence in how people move. https://medicalxpress.com/news/2025-12-baby-ease-chronic-pain.html Mon, 01 Dec 2025 06:38:20 EST news683793482 Engineers and obstetricians at Monash University have invented a wearable Band-Aid-like patch to track a baby's movements through the mother's abdomen, offering a new way to support safer pregnancies from home. https://medicalxpress.com/news/2025-11-patch-baby-movements-utero.html Fri, 28 Nov 2025 09:18:35 EST news683543793 Parkinson's disease affects more than 1.1 million people in the United States, progressively damaging the brain cells that control movement. By the time symptoms like tremors appear, patients have already lost around half of the affected brain cells, making early detection crucial. https://medicalxpress.com/news/2025-11-brain-markers-yield-early-clues.html Tue, 25 Nov 2025 13:07:04 EST news683298422 Whether speaking or swinging a bat, precise and adaptable timing of movement is essential for everyday behavior. Although we do not have sensory organs like eyes or a nose to sense time, we can keep time and control the timing of our actions. Such timing accuracy depends on a timer in the brain, but how the brain implements this timer was previously unknown. https://medicalxpress.com/news/2025-11-rewind-brain-action.html Wed, 19 Nov 2025 11:00:04 EST news682684441 Yi Du and colleagues from the Chinese Academy of Sciences published an article in the open access journal PLOS Biology detailing their findings about a new way our bodies naturally respond to music.

When he woke up, he couldn't move his left arm or leg. Lewis's neighbor realized his truck hadn't moved in two days and called 911 for a welfare check. When paramedics found him, he was paralyzed on one side. https://medicalxpress.com/news/2025-11-robotic-overlooked-sensory-deficits-survivors.html Tue, 18 Nov 2025 09:36:04 EST news682680962 People often take walking for granted. We just move, one step after another, without ever thinking about what it takes to make that happen. Yet every single step is an extraordinary act of coordination, driven by precise timing between spinal cord, brain, nerves, muscles and joints. https://medicalxpress.com/news/2025-11-motion-medicine-ai-capture-wearables.html Mon, 10 Nov 2025 13:05:05 EST news682002302 In a new JNeurosci paper, Kahori Kita and colleagues at Johns Hopkins University explored how people switch between intuitive motor skills they know and newly learned movement patterns. https://medicalxpress.com/news/2025-11-people-movement-patterns-alternate.html Mon, 10 Nov 2025 13:00:01 EST news681985561 Researchers at UC San Francisco have developed a new way to improve walking for patients with Parkinson's disease using deep brain stimulation and artificial intelligence. https://medicalxpress.com/news/2025-11-qa-tech-parkinson-patients.html Sun, 09 Nov 2025 20:20:01 EST news681732946 A study of 307 youth from a diverse population across the United States whose health data were documented from birth into adulthood revealed that earlier sleep timing, more efficient sleep, and less variable sleep patterns during adolescence predicted better young adult cardiovascular health (CVH). The study, led by researchers in Stony Brook University's Program in Public Health, is published in JACC: Advances. https://medicalxpress.com/news/2025-10-regularity-habits-adolescence-young-adult.html Wed, 29 Oct 2025 11:54:15 EDT news680957649 Researchers at the University of California San Diego have created a model driven by generative AI that will help prevent injuries in athletes and also aid in rehabilitation after an injury. The model could also help athletes train better. https://medicalxpress.com/news/2025-10-generative-ai-athletes-injuries.html Mon, 27 Oct 2025 14:34:03 EDT news680794442 ALS, also known as Lou Gehrig's disease, is among the most challenging neurological disorders: relentlessly progressive, universally fatal, and without a cure even after more than a century and a half of research. Despite many advances, a key unanswered question remains—why do motor neurons, the cells that control body movement, degenerate while others are spared? https://medicalxpress.com/news/2025-10-als-body-movement-hidden-burden.html Mon, 27 Oct 2025 06:00:02 EDT news680515561 A new study by investigators from Mass General Brigham has used next-generation imaging technology to discover that when the brain is falling asleep, it shows a coordinated shift in activity. https://medicalxpress.com/news/2025-10-brain-energy-blood-people-fall.html Fri, 24 Oct 2025 05:00:01 EDT news680456401 Physiotherapy isn't just for adults recovering from injuries.
