Ancient DNA Reveals Secrets of High Modern Alzheimer’s and MS Rates

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.

RNA Interference Plays Key Role in Alzheimer’s Disease

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.

Five Biological Variants of Alzheimer’s Discovered

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.

Novel Gene Linked to Range of Neurodegenerative Diseases Identified

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. In its mutated form, ANG causes stem cells to delay their differentiation into specialized nerve cells, leading to neurodevelopmental defects.

Stomach Bug Linked to Alzheimer’s Risk

A new study reveals a potential link between Helicobacter pylori infection and an increased risk of Alzheimer’s disease. Analyzing three decades of patient data, the researchers found that people over 50 with symptomatic H. pylori infection face an 11% higher risk of developing Alzheimer’s, which escalates to 24% a decade post-infection.

Novel Nanoparticle Delivery System Targets Alzheimer’s Inflammation

A new study demonstrates a breakthrough in Alzheimer's disease (AD) treatment using lipid nanoparticles (LNPs) to deliver small interfering RNA (siRNA) to the brain's microglia. This approach effectively suppresses a protein linked to Alzheimer's-related inflammation.

Rare Gene Mutation Shields Woman from Alzheimer’s

Researchers uncovered why a Colombian woman, despite carrying a genetic defect for Alzheimer’s, remained cognitively healthy into her 70s. The key lies in her possession of two copies of the rare Christchurch mutation in the APOE gene, which they replicated in a mouse study.

Serotonin Drop Linked to Memory Decline in Early Alzheimer’s Progression

Researchers discovered a potential link between lower levels of serotonin, the "happiness" chemical, and mild cognitive impairment (MCI), which could advance our understanding of Alzheimer's Disease (AD). Their study indicates that individuals with MCI have significantly reduced serotonin transporter levels, a factor that might contribute to memory problems and potentially AD.

Light Therapy Shines in Treating Alzheimer’s Sleep and Mood Issues

A new study highlights the efficacy of light therapy in enhancing sleep and reducing psycho-behavioral symptoms in Alzheimer’s patients. This non-pharmacological treatment, targeting the brain's sleep modulator, shows significant promise in mitigating apathetic and depressive behaviors, agitation, and aggression commonly associated with Alzheimer’s cognitive decline.

Brain Stimulation Enhances Alzheimer’s Cognitive Function

Transcranial direct current stimulation (tDCS) may enhance cognitive function in Alzheimer’s disease patients. The study involved 140 patients with mild to moderate Alzheimer’s, who received either active or sham tDCS twice daily for up to six weeks.
