Analyzing data from over 1,000 patients globally, they found that 94% of PCA cases predict Alzheimer's, with the rest linked to conditions like Lewy body disease. ]]> https://neurosciencenews.com/early-alzheimers-vision-25510/feed/ 0 https://neurosciencenews.com/evolution-genetics-ms-alzheimers-25506/ https://neurosciencenews.com/evolution-genetics-ms-alzheimers-25506/#comments Mon, 22 Jan 2024 15:11:00 +0000 https://neurosciencenews.com/?p=99607 Researchers have created a vast gene bank from nearly 5,000 ancient humans, offering unprecedented insights into the historical spread of genes and diseases. This groundbreaking study linked the spread of multiple sclerosis (MS) genes to ancient migrations and discovered that genes increasing the risk of diseases like Alzheimer's originated from hunter-gatherers. ]]> https://neurosciencenews.com/evolution-genetics-ms-alzheimers-25506/feed/ 1 https://neurosciencenews.com/srna-alzheimers-25481/ https://neurosciencenews.com/srna-alzheimers-25481/#respond Thu, 18 Jan 2024 14:29:57 +0000 https://neurosciencenews.com/?p=99513 A new study suggests that RNA interference plays a crucial role in the disease. Researchers discovered that aging and Alzheimer’s-affected brains have an imbalance between toxic and protective short RNAs (sRNAs), leading to brain cell death and DNA damage. ]]> https://neurosciencenews.com/srna-alzheimers-25481/feed/ 0 https://neurosciencenews.com/alzheimers-biological-variants-25441/ https://neurosciencenews.com/alzheimers-biological-variants-25441/#comments Wed, 10 Jan 2024 15:04:30 +0000 https://neurosciencenews.com/?p=99328 Researchers have identified five biological variants of Alzheimer's disease through cerebrospinal fluid analysis, shedding new light on the complexity of the condition. These variants differ in amyloid production, blood-brain barrier integrity, nerve cell growth, protein synthesis, and immune system functioning. ]]> https://neurosciencenews.com/alzheimers-biological-variants-25441/feed/ 1 https://neurosciencenews.com/ang-gene-neurodegeneration-25433/ https://neurosciencenews.com/ang-gene-neurodegeneration-25433/#respond Mon, 08 Jan 2024 20:25:11 +0000 https://neurosciencenews.com/?p=99288 Researchers uncovered a crucial link between the gene Angiogenin (ANG) and age-related neurodegenerative diseases such as frontotemporal dementia (FTD), motor neuron disease (MND), and Parkinson's disease.
