Scientists explore early life factors contributing to SMA

Spinal muscular atrophy (SMA) is a severe neurological disease for which there is presently no cure, although current therapies can alleviate symptoms. In the search for better treatment options, scientists at DZNE and the Dresden University of Technology are now drawing attention to previously unnoticed abnormalities in embryonic development. They base their argument on studies of so-called organoids: Laboratory-grown tissue cultures that can reconstruct disease processes. Their findings are published in the journal Cell Reports Medicine.

Comprehensive analysis of Alzheimer’s brain tissue identifies novel biomarkers

From studying the human genome, to analyzing the way proteins are encoded, or monitoring RNA expression, researchers are rapidly gaining a far richer understanding of the complex genetic and cellular mechanisms that underpin dementia. But there's a catch: While new technologies are revealing myriad avenues for Alzheimer's research, it's impossible to know in advance which research pathways will lead to effective treatments.

Cognitive decline persists in older adults long after severe COVID-19 recovery

Older adults recovering from COVID-19 experience varying degrees of cognitive decline over 2.5 years, with severe cases showing the most significant impact. Early cognitive care and monitoring are crucial for improving outcomes.

High belly and arm fat linked to Alzheimer's and Parkinson's risk

People with high levels of body fat stored in their belly or arms may be more likely to develop diseases like Alzheimer's and Parkinson's than people with low levels of fat in these areas, according to a study published in the July 24, 2024, online issue of Neurology, the medical journal of the American Academy of Neurology.

Chronic and new anxiety tied to increased dementia risk

In a study published in the Journal of the American Geriatrics Society, both chronic and new anxiety were associated with an increased risk of dementia. However, where anxiety had resolved, there was no association with dementia risk.
