Soma statt Signale von außen: Wie Neuronen ihren Axon-Pfad auswählen – it boltwise

by

Researchers have uncovered a fundamental mechanism in developmental neurobiology that explains how neurons determine the path of their axons—the long, slender projections that carry electrical impulses to other cells. Contrary to long-standing theories that relied exclusively on external environmental guidance cues, recent findings indicate that the neuron’s cell body, or soma, plays a decisive role … Read more

Gefahr durch Zugluft?: TV-Star im Gesicht gelähmt – Arzt vermutet Klimaanlage – n-tv.de

by

TV personality Kater Merlan has reported sudden facial paralysis following exposure to strong drafts and air conditioning at a festival. While her treating physician suspects the temperature drop and airflow triggered the condition, medical consensus generally attributes such paralysis, known as Bell’s palsy, to viral inflammation of the seventh cranial nerve. Merlan shared the experience … Read more

Afternoon Confusion: The Classic Dementia Warning Sign Doctors Urge You to Never Ignore

by

Medical professionals frequently identify a phenomenon known as “sundowning”—or sundown syndrome—as a common behavioral manifestation associated with various forms of dementia, particularly Alzheimer’s disease. This condition is characterized by a distinct increase in confusion, agitation, and restlessness that typically emerges during the late afternoon or early evening hours. According to the National Institute on Aging … Read more

641 New Genes Linked to Schizophrenia Risk: Are You at Higher Risk? Scientists Reveal Key Genetic Breakthroughs

by

Scientists have discovered 641 new genes associated with an increased risk of schizophrenia, more than doubling the previously known genetic links to the complex psychiatric disorder. According to a study published in the journal Nature Mental Health, the findings—led by an international consortium including researchers from the Broad Institute of MIT and Harvard—could revolutionize early … Read more

Diabetes Medications: SGLT2 Inhibitors and GLP-1 Agonists Reduce Alzheimer’s Risk by 43% and 33%

by

Recent clinical research indicates that patients with Type 2 diabetes treated with SGLT2 inhibitors may experience a significantly lower incidence of Alzheimer’s disease compared to those using other glucose-lowering medications. According to a large-scale study published in The BMJ, the use of sodium-glucose cotransporter-2 (SGLT2) inhibitors is associated with a reduced risk of dementia, suggesting … Read more

Study Links Plasma Vitamin C Levels to Gray Matter and Brain Network Connectivity

by

Recent neuroimaging research suggests a measurable link between plasma Vitamin C levels and the structural integrity of the human brain, specifically concerning gray matter volume and the connectivity of the Default Mode Network (DMN). A study published in Frontiers in Nutritional Neuroscience indicates that higher concentrations of circulating ascorbate may correlate with enhanced neurological resilience, … Read more

How Oral Hygiene and Gum Bacteria Affect the Risk of Alzheimer’s and Parkinson’s Disease

by

The connection between oral health and systemic disease has long been a subject of clinical interest, but recent research is shedding new light on how the health of our gums and teeth may influence complex neurodegenerative conditions. As we navigate the complexities of aging and brain health, the potential impact of chronic inflammation originating in … Read more

Unlocking Brain Aging Secrets: How Cutting-Edge Genomic Tools Are Revolutionizing Neuroscience & Longevity Research

by

Decoding Brain Aging: How Genomic Tools Are Rewriting Our Understanding of Cognitive Decline By Dr. Helena Fischer, Editor, Health | Berlin, Germany | May 13, 2026 Our brains don’t age like the rest of our bodies. While our skin wrinkles and our joints stiffen with predictable patterns, cognitive decline is far more mysterious—a silent, creeping … Read more

Early Warning Signs of Parkinson’s Disease Discovered in the Gut

by

For decades, the clinical diagnosis of Parkinson’s disease has largely been a reactive process. Physicians typically identify the condition only after motor symptoms—such as tremors, rigidity, and bradykinesia—become apparent. By the time these visible signs emerge, a significant portion of dopamine-producing neurons in the brain have already been lost, leaving clinicians to manage the disease … Read more

Sleep Disorders Linked to Parkinson’s in Just 11.1% — Why This Low Rate Is Surprisingly Significant

by

When it comes to Parkinson’s disease, the tremors and stiffness that most people associate with the condition often appear only after years of silent progression. Long before motor symptoms become obvious, subtle changes in sleep patterns may be among the earliest warning signs — yet remarkably few people recognize this connection. A striking insight from … Read more
