If you’ve ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather in their spiny extensions called dendrites.

Arizona State University and Banner Alzheimer’s Institute researchers, along with their collaborators, have discovered a surprising link between a chronic gut infection caused by a common virus and the development of Alzheimer’s disease in a subset of people.

The biogenic polyamine spermidine has received a lot of attention since it was scientifically shown to slow down the aging process when taken in adequate quantities. Determining the spermidine levels in foodstuffs requires the right analysis strategy given that many have a highly complex matrix. Scientists at the Westphalian University in Recklinghausen, Germany have developed an efficient, fully automated method based on HPLC-TOF-MS to determine spermidine in the “superfood” Apilarnil.

Delivering drugs to the brain is a major challenge due to the protective blood-brain barrier. Now, researchers have uncovered how tiny gas-filled microbubbles, activated by ultrasound, can create microscopic jets that gently pierce cell membranes — allowing medication to reach its target with unprecedented precision.

A study by researchers from the Brigham and Women’s Hospital has found that dementia was more frequently diagnosed within one year of a fall compared to other types of injuries among older adults.

A new Cornell study reveals that deep sleep does more than recharge your body — it resets your brain’s memory circuits. This breakthrough explains how we keep learning without maxing out our neurons, offering insights into boosting memory and potentially treating conditions like Alzheimer’s and PTSD.

A new report has revealed that prolonged exposure to extreme hot and cold temperatures in the UK in the background of climate change not only carries greater risk of death but could also be linked to many other health issues.

A new study in Frontiers in Neuroscience highlights a potential link between light pollution and Alzheimer's disease (AD), particularly for those under 65. Researchers found that nightly exposure to outdoor light may increase AD risk, suggesting that younger people may be especially vulnerable.

Scientists have graphically illustrated global concentrations of a major air pollutant for the first time using Air Quality Stripes, revealing stark contrasts in air quality improvements across Europe and worsening conditions in parts of Africa and Central Asia. The visualizations highlight global disparities in air pollution.

Researchers have conducted a study which helps to detect early signs of dementia by studying the natural speech of seniors. They revealed that participants with memory-related mild cognitive impairment spoke less and used fewer, but more abstract, nouns that is consistent with the speech pattern of Alzheimer’s patients.
