New guidelines developed for the diagnosis and management of premature ovarian insufficiency

New guidelines on the diagnosis and management of premature ovarian insufficiency (POI) – developed by the Centre for Research Excellence in Women's Health in Reproductive Life (CRE-WHiRL) at Monash University, and key international women's health organizations with an international team of experts including women with lived experience – will be published today (TBC) simultaneously in three leading journals.

Early bilateral oophorectomy linked to increased Alzheimer's disease risk

Women with early bilateral oophorectomy face higher Alzheimer's risk, especially with APOE4 allele; education and hormone therapy may offer resilience.

New insights into the mechanisms of "Niemann-Pick type C" in children

In the journal "Science Translational Medicine", scientists from DZNE and LMU Hospital report on new insights into the mechanisms of "Niemann-Pick type C" (NPC), a rare neurodegenerative disease associated with dementia that can manifest as early as childhood.

Neighborhood disadvantage found to affect blood pressure and cognition

New research from Wake Forest University School of Medicine suggests that living in a disadvantaged neighborhood is associated with higher blood pressure and lower cognitive scores, even among people who do not have an existing diagnosis of mild cognitive impairment.

Antipsychotics linked to increased behavioral problems in nursing homes

A new study conducted by researchers at the University of Waterloo analyzed data from nearly 500,000 Canadian patients who lived in nursing homes across Canada between 2000 and 2022.

Reimagining axons with the pearls-on-a-string model

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell – and propose a new model for understanding how information is transmitted in the brain.

Chronic traumatic encephalopathy risk in ice hockey increases with each year played

A study of 77 male hockey players reveals a 96.4% CTE prevalence, highlighting the link between play duration and increased risk of chronic encephalopathy.

New computational pipeline identifies key biomarkers for Alzheimer's disease

Researchers at Columbia University Mailman School of Public Health have developed a novel computational pipeline designed to identify protein biomarkers associated with complex diseases, including Alzheimer's disease (AD).

Early ovarian removal and APOE4 increase Alzheimer's risk in women

New research published by a team of researchers from the University of Toronto in collaboration with colleagues from the University of Alberta has found that women who have had both ovaries surgically removed before the age of 50 and carry a variant of the apolipoprotein gene, the APOE4 allele, are at high risk of late-life Alzheimer disease (AD). Use of hormone therapy mitigates this risk.

Scientists link proteins to Alzheimer’s through cutting-edge genetic method

Researchers have developed MR-SPI, a novel method integrated with AlphaFold3, to identify causal protein biomarkers and predict their 3D structural changes in Alzheimer’s disease. This breakthrough offers insights into disease mechanisms and potential therapeutic targets.

Frontotemporal dementia disrupts empathy for pain, study reveals

Study reveals diminished brain activity related to empathy for pain in individuals with behavioral variant frontotemporal dementia (bvFTD), using task-based fMRI. Findings show a stark reduction in neural responses tied to affective empathy, highlighting early bvFTD impacts on social cognition.

Ketone body β-hydroxybutyrate restores protein balance and targets Alzheimer’s-linked aggregates

Scientists identify β-hydroxybutyrate as a key regulator of protein solubility, offering a novel pathway to combat neurodegeneration in aging and Alzheimer’s disease.

Alzheimer's genetic risk studies undermined by systemic biases

Recent research in Nature Genetics reveals pervasive biases in GWAX studies using parental history of Alzheimer’s, highlighting potential misdirection in genetic associations and disease risk predictions. A novel GSUB method identifies false signals stemming from confounding factors like survival bias and socioeconomic status.
