‘Playing to your strengths’ improves well-being in adult ADHD, new research shows

Adults with ADHD who recognize and regularly use their personal strengths report better well-being, improved quality of life and fewer mental health difficulties, according to a new international study.

During October’s ADHD Awareness Month, which this year focuses on “the many faces of ADHD,” researchers from the University of Bath, King’s College London, and Radboud University Medical Center in the Netherlands have delivered the first large-scale study to quantify psychological strengths in ADHD.

The study, published in Psychological Medicine, compared 200 adults with ADHD and 200 adults without ADHD on how much they identified with 25 positive traits—including creativity, humor, spontaneity and hyperfocus—defined by researchers as “things [they] do well or best.”

Social threat perceptions in youth linked to altered brain connectivity

Researchers at UCL Institute of Education, King’s College London, Harvard T.H. Chan School of Public Health, and UCLA report that perceived social threats in early adolescence are associated with altered connectivity in default mode, dorsal attention, frontoparietal, and cingulo-opercular networks and with higher mental health symptom scores months later.

Adolescence is a difficult age, a time of rapid neurobiological and psychological change amidst shifting . In 2021, CDC reported that 40% of U.S. struggled with persistent sadness or hopelessness, and more than one in six had made a suicide plan.

Perceived threats in a child’s social environment, within the family, at school, and in the neighborhood, are known risk factors for adolescent psychopathology.

Instructions help you remember something better than emotions or a good night’s sleep, scientists find

A good night’s sleep has long been understood to help us consolidate new memories, but we don’t understand how. Associations with negative feelings like fear or stress can improve recall, but intentionally trying to remember can also be effective. But these two mechanisms are very different—one involuntary, one deliberate. Which influences memory most?

To investigate, researchers asked participants to remember or forget words, some of which had negative emotional associations. They found that instructions improved recall more than emotion.

“What we intend to remember and to forget can be powerful,” said Dr. Laura Kurdziel of Merrimack College, lead author of the article in Frontiers in Behavioral Neuroscience. “We have more control over our memories than we often think we do.”

Scientists reverse Alzheimer’s in mice using nanoparticles

A research team co-led by the Institute for Bioengineering of Catalonia (IBEC) and West China Hospital Sichuan University (WCHSU), working with partners in the UK, has demonstrated a nanotechnology strategy that reverses Alzheimer’s disease in mice.

Unlike traditional nanomedicine, which relies on nanoparticles as carriers for therapeutic molecules, this approach employs nanoparticles that are bioactive in their own right: “supramolecular drugs.” The work has been published in Signal Transduction and Targeted Therapy.

Instead of targeting neurons directly, the therapy restores the proper function of the blood-brain barrier (BBB), the vascular gatekeeper that regulates the brain’s environment. By repairing this critical interface, the researchers achieved a reversal of Alzheimer’s pathology in animal models.

Epigenetic shifts link maternal infection during pregnancy to higher risk of offspring developing schizophrenia

The health of mothers during pregnancy has long been known to play a role in the lifelong mental and physical health of offspring. Recent studies have found that contracting an infection during pregnancy can increase the risk that offspring will develop some neurodevelopmental disorders, conditions that are associated with the atypical maturation of some parts of the brain.

An infection is an invasion of pathogens, such as bacteria, viruses, fungi or parasites, which can then multiply and colonize host tissues. Findings suggest that when an expecting mother contracts an infection, her immune system can respond to it in ways that could impact the development of the fetus.

Researchers at University of Manchester and Manchester Metropolitan University recently carried out a study aimed at further investigating the processes through which maternal infections during pregnancy could increase the risk that offspring will develop schizophrenia later in life. Schizophrenia is a typically debilitating mental health condition characterized by hallucinations, false beliefs about oneself or the world (e.g., delusions) and cognitive impairments.

Synaptic changes in the brains of patients with frontotemporal dementia can be modeled in the laboratory

Neurons produced from frontotemporal dementia patients’ skin biopsies using modern stem cell technology recapitulate the synaptic loss and dysfunction detected in the patients’ brains, a new study from the University of Eastern Finland shows.

Frontotemporal dementia is a progressive neurodegenerative disease affecting the frontal and temporal lobes of the brain. The most common symptoms are , difficulties in understanding or producing speech, problems in movement, and psychiatric symptoms.

Often, has no identified genetic cause, but especially in Finnish patients, hexanucleotide repeat expansion in the C9orf72 gene is a common genetic cause, present in about half of the familial cases and in 20% of the sporadic cases where there is no family history of the disease.

Fat particles could be key to treating metabolic brain disorders

Evidence challenging the long-held assumption that neuronal function in the brain is solely powered by sugars has given researchers new hope of treating debilitating brain disorders. A University of Queensland study led by Dr. Merja Joensuu and published in Nature Metabolism showed that neurons also use fats for fuel as they fire off the signals for human thought and movement.

“For decades, it was widely accepted that relied exclusively on glucose to fuel their functions in the brain,” Dr. Joensuu said. “But our research shows fats are undoubtedly a crucial part of the neuron’s in the brain and could be a key to repairing and restoring function when it breaks down.”

Dr. Joensuu from the Australian Institute for Bioengineering and Nanotechnology along with lab members Ph.D. candidate Nyakuoy Yak and Dr. Saber Abd Elkader from UQ’s Queensland Brain Institute set out to examine the relationship of a particular gene (DDHD2) to hereditary spastic paraplegia 54 (HSP54).

Neuroscientists can now predict dementia from the way you breathe in your sleep

Scientists have discovered that disrupted breathing during sleep, particularly conditions like sleep apnea, creates a measurable cascade of brain changes that predicts cognitive decline with startling accuracy.

Recent research analyzing over one million health records found that people with sleep-disordered breathing face between 1.3 and 5.11 times higher risk of developing various forms of dementia, depending on the specific condition.

The most dramatic finding: those with documented sleep breathing problems showed dementia risk ratios that peaked above five-fold for certain neurodegenerative diseases.
