For younger women, mental health now may predict heart health later

Younger women are generally thought to have a low risk of heart disease, but new research urges clinicians to revisit that assumption, especially for women who suffer from certain mental health conditions. A new study found that having anxiety or depression could accelerate the development of cardiovascular risk factors among young and middle-aged women. http://dlvr.it/T4mjpC

Mechanism found to determine which memories last

Resim
Neuroscientists have established in recent decades the idea that some of each day's experiences are converted by the brain into permanent memories during sleep the same night. Now, a new study proposes a mechanism that determines which memories are tagged as important enough to linger in the brain until sleep makes them permanent. http://dlvr.it/T4mTyP

Researchers introduce enhanced brain signal analysis technique

Resim
Researchers have introduced a new, refined method for analyzing brain signals, enhancing our understanding of brain functionality. This research has the potential to improve treatments for neurological conditions such as Parkinson's disease, pain, epilepsy and depression. http://dlvr.it/T4lMqw

Could AI play a role in locating damage to the brain after stroke?

Resim
Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4). http://dlvr.it/T4lMXm

Making long-term memories requires nerve-cell damage

Resim
Just as you can't make an omelet without breaking eggs, scientists have found that you can't make long-term memories without DNA damage and brain inflammation. http://dlvr.it/T4k0DY

Risk factors for faster aging in the brain revealed in new study

Resim
Researchers have used data from UK Biobank participants to reveal that diabetes, traffic-related air pollution and alcohol intake are the most harmful out of 15 modifiable risk factors for dementia. http://dlvr.it/T4jzxF

Not unique to humans but uniquely human: researchers identify factor involved in brain expansion in humans

Resim
What makes us human? According to neurobiologists it is our neocortex. This outer layer of the brain is rich in neurons and lets us do abstract thinking, create art, and speak complex languages. An international team has identified a new factor that might have contributed to neocortex expansion in humans. http://dlvr.it/T4jlyl

Study finds high prevalence of hidden brain changes in people with heart disease

Resim
A new analysis involving over 13,000 people has found changes to blood vessels in the brain that can increase the risk of stroke and dementia are common in people with a range of heart conditions, regardless of whether they have experienced a stroke. http://dlvr.it/T4gJFy

Large-scale animal study links brain pH changes to wide-ranging cognitive issues

Resim
The International Brain pH Project Consortium unveils groundbreaking findings in a large-scale animal model study, indicating altered brain pH and lactate levels as a transdiagnostic endophenotype in neuropsychiatric disorders with cognitive impairment. This collaborative effort, involving 131 researchers across six countries, challenges existing notions and may pave the way for novel strategies in understanding and addressing biologically diverse and debilitating disorders impacting cognitive function. http://dlvr.it/T4fVN6

Human brains are getting larger: That may be good news for dementia risk

Resim
A new study has found human brains are getting bigger. The increased size may lead to a brain reserve, potentially reducing the risk of dementia. http://dlvr.it/T4cSxM

The aging brain: Protein mapping furnishes new insights

Resim
For the neurons in the brain to work smoothly and be able to process information, the central nervous system needs a strictly regulated environment. This is maintained by the blood-brain barrier, whereby specialized brain endothelial cells lining the inner walls of blood vessels regulate the exchange of molecules between the circulatory and nervous systems. Earlier studies have shown that various functions that are dependent on these cells, such as the integrity of the blood-brain barrier or the regulation of blood supply to the brain, decline over the course of a person's life. This dysregulation leads to a dysfunction of the brain vasculature and is therefore a major contributor to medical conditions such as strokes and dementia. http://dlvr.it/T4cChz

Is the secret to anxiety in young women hidden in our brain chemistry?

Resim
The development of anxiety in girls and young women may stem from an imbalance between two crucial brain chemicals, gamma-aminobutyric acid (GABA) and glutamate, according to a new study. This discovery offers promising insights into potential treatment avenues for girls and women dealing with anxiety. http://dlvr.it/T4cCQ6

The power of neighbors: Neighboring synapses shape learning and memory

Resim
A researcher has developed a new model that provides a holistic view on how our brain manages to learn quickly and forms stable, long-lasting memories. Their study sheds light on the crucial role of interactions among neighboring contact sites of nerve cells for brain plasticity -- the brain's ability to adapt to new experiences. http://dlvr.it/T4btwT

How neurochemicals affect fMRI readings

Resim
A new study shows how neurochemicals can influence blood vessels. The findings may change how researchers interpret results from functional magnetic resonance imaging studies. http://dlvr.it/T4TqT9

Brain recordings in people before surgery reveal how all minds plan what to say prior to speaking

Resim
A new study in people undergoing surgery to treat seizures related to epilepsy shows that pauses in speech reveal information about how people's brains plan and produce speech. http://dlvr.it/T4TqKc

Movement disorder ALS and cognitive disorder FTLD show strong molecular overlaps, new study shows

Resim
Single-cell gene expression patterns in the brain motor and frontal cortex, and evidence from follow-up experiments, reveal many shared cellular and molecular similarities that could be targeted for potential treatment. http://dlvr.it/T4TZpw

Five factors to ensure an infant thrives

Researchers make the case that five 'Thrive Factors' are a key element of healthy human brain, behavioral and cognitive development. http://dlvr.it/T4SRcd

Research offers hope for preventing post-COVID 'brain fog' by targeting brain's blood vessels

Resim
Researchers have identified a mechanism that causes neurological problems in mice infected with SARS-CoV-2, the virus behind COVID-19. The researchers also found a treatment that helped prevent these changes. http://dlvr.it/T4R4q1

Abnormal brain structure identified in children with developmental language problems

Resim
A rigorous analysis of numerous studies concludes that a part of the brain traditionally associated with movement is abnormal in children with developmental language impairments. The discovery has the potential to improve both the diagnosis and treatment of the language difficulties. http://dlvr.it/T4NFn3

Metformin during pregnancy affects the brain development in offspring mice, study finds

Resim
With the rise in gestational diabetes and metabolic disorders during pregnancy, metformin is also being prescribed more frequently. Although it is known that the oral antidiabetic agent can cross the placental barrier, the impacts on the brain development of the child are largely unknown. Researchers have now been able to demonstrate in a mouse model that although metformin has positive effects in pregnant animals, it does not in the offspring. http://dlvr.it/T4N0yW
