Researchers have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental…
There are over six million Americans with heart failure who are at greater risk of losing their cognitive abilities earlier in life, a study suggests. Global cognition and executive functioning declined more rapidly over…
The same genes could hold the key to regenerating cells in the ear and eye, according to a new mouse study. Researchers focused on a group of interacting genes called the Hippo pathway, which serve as a 'stop growing'…
A newly developed blood test for Alzheimer's disease not only aids in the diagnosis of the neurodegenerative condition but also indicates how far it has progressed, according to a new study.
Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more…
Stroke survivors who have attended some level of higher education may face even steeper mental declines, according to a study. The findings suggest that attending higher education may enable people to retain greater…
Researchers developed olfactory tests -- in which participants sniff odor labels that have been placed on a card -- to assess people's ability to discriminate, identify and remember odors. They found that participants…
For women in their 80s, experiencing increasing sleepiness during the day over a five-year period is associated with double the risk of developing dementia during that time, according to a new study. The study does not…
Researchers have developed a powerful AI tool, built on the same transformer architecture used by large language models like ChatGPT, to process an entire night's sleep. To date, it is one of the largest studies…
A new study suggests a promising alternative to previous attempts to remove the sticky, toxic amyloid beta plaques from brains with Alzheimer's Disease: enhancing the brain's own immune cells to clear these plaques more…
Hearing begins with the stretching of elastic molecular 'springs' that open ion channels in the sensory hair cells of the ear. For decades, researchers have known that these gating springs must exist, but they could not…
Results from a phase 1/2 clinical trial of a novel stem cell treatment for cornea injuries found 14 patients treated and tracked for 18 months had a more than 90% success rate at restoring the cornea's surface and…
Researchers have discovered a novel approach to protecting insulin-producing beta cells from the damaging effects of glucolipotoxicity - a harmful condition linked to the progression of type 2 diabetes (T2D). These…
Sleep quality and disorders are influenced by enduring patterns of thoughts, emotions and behaviours known as personality traits.
Sleep plays a pivotal role in shaping emotional health and fostering resilience in the face of stress. Through coordinated ...
Chronic pain, defined as pain persisting for more than three months, presents multifaceted challenges that extend beyond sensory ...
Chronic pain disorders are sustained by maladaptive neuroplastic changes across cortical and subcortical networks. Central ...
Health psychology examines the interplay between psychological processes, behaviours and physical well-being. Drawing on the ...
Cognitive behavioural interventions for insomnia and related sleep disorders have emerged as first-line treatments that target ...
Researchers published a study analyzing more than 30 years of aging and dementia patterns of 678 nuns.
A new artificial intelligence model measures how fast a patient's brain is aging and could be a powerful new tool for understanding, preventing and treating cognitive decline and dementia.
Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough -- particularly if you are older. It may even put you at risk for cognitive impairment.
A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new, and important or just 'background noise.'
After a week of stress, mice show changes in how their brains process sound, reducing how well they perceive loud noises, according to a new study.
Years before tau tangles show up in brain scans of patients with Alzheimer's disease, a biomarker test can detect small amounts of the clumping-prone tau protein and its misfolded pathological forms that litter the…
A research team has discovered that the two key pathological hallmarks of Alzheimer's -- tau protein and beta-amyloid -- affect brain circuits in distinct yet synergistic ways, particularly those linked to memory and…
A new study has found that certain bacteria were associated with better memory and attention, while others were linked to an increased risk of Alzheimer's disease.
A paradigm-shifting study shows an experimental drug, GL-II-73, has the potential to restore memory and cognitive function in a mouse model of Alzheimer's disease. The study demonstrates that the drug improves memory…
Insomnia is characterised by difficulties initiating or maintaining sleep despite adequate opportunity, leading to daytime ...
Being more social by visiting friends, attending parties and going to church may help keep your brain healthy, according to new research.
