 High-dose DHA reaches the brain but fails to protect memoryHigh-dose DHA reaches the brain but fails to protect memory
 
High-dose DHA effectively increased brain levels in older adults at Alzheimer's risk, but did not lead to cognitive or structural brain health improvements.
 
 
 Blood metabolites reveal lifestyle links to brain health before dementiaBlood metabolites reveal lifestyle links to brain health before dementia
 
Blood metabolome profiling in dementia-free middle-aged adults linked 14 metabolites to cognition and 22 metabolites to MRI markers of brain health. Lifestyle, clinical factors, medication use and gut microbiota appeared to shape many of these metabolites, with ergothioneine emerging as a notable cognition-linked signal.
 
   Brighter daytime light is linked to a lower dementia riskBrighter daytime light is linked to a lower dementia risk
 
The study finds that greater exposure to daytime light may lower dementia risk, pointing to light's role in enhancing circadian rhythms and cognitive function.
 
   Longer hormone exposure linked to healthier brain aging in womenLonger hormone exposure linked to healthier brain aging in women
 
Research indicates that hormonal therapies and later menopause are associated with increased brain volume and thickness, promoting healthier aging.
 
 Lifetime estrogen exposure linked to improved brain health in women
 
Lifetime estrogen exposure linked to improved brain health in womenResearchers from the University of Kansas have shown a link between reproductive hormone exposure throughout life and brain health in 459 women aged 65 to 80.
 
 
 New review highlights TREM-1 receptor as target for inflammatory diseases
 
New review highlights TREM-1 receptor as target for inflammatory diseasesA comprehensive review recently published in Current Molecular Pharmacology consolidates the growing evidence surrounding the Triggering Receptor Expressed on Myeloid Cells-1 (TREM-1) as a central amplifier of innate immune responses and a promising therapeutic target for a range of inflammatory diseases.

 Study links COVID-19 to higher sleep apnea risk years after infection
 
Study links COVID-19 to higher sleep apnea risk years after infectionResearchers analyzed more than 910,000 adults and found that SARS-CoV-2 infection was associated with a higher adjusted risk of new-onset obstructive sleep apnea up to 4.5 years later. The association appeared in both hospitalized and non-hospitalized COVID-19 patients, supporting targeted screening in higher-risk post-COVID groups while highlighting the need for objective sleep testing.
 
 
 Hidden costs push United States dementia toll to historic high
 
Hidden costs push United States dementia toll to historic highA new USC-led study finds Alzheimer's disease and related dementias will cost the United States an estimated $818 billion this year, driven largely by often-overlooked costs to persons living with dementia and family and friends providing their care.
 
 
 Higher daytime light exposure linked to lower dementia risk
 
Higher daytime light exposure linked to lower dementia riskNew research in General Psychiatry has uncovered a link between higher levels of daytime light exposure and a lower risk of dementia.
 
 
 Iron overload gradually increases neurons' vulnerability to neurodegeneration
 
Iron overload gradually increases neurons' vulnerability to neurodegenerationNeurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's Foundation report roughly 7 million people with Alzheimer's and another million with Parkinson's.
 
 
 Study compares menopause symptom burden across different age groups
 
Study compares menopause symptom burden across different age groupsThere has been a lot of discussion about how the age at menopause can affect menopause symptoms. A new study compared the prevalence and severity of menopause symptoms in women experiencing menopause around the average age of 51 years and those with premature ovarian insufficiency, showing similar symptom burden in the psychological and urogenital domains.
