Smell Test at Home May Sniff Out Early Cognitive Decline

A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.

Type 2 Diabetes Rewires the Brain Like Early Alzheimer’s

New research reveals that Type 2 diabetes may impair the brain’s reward and memory processing in ways that mirror early Alzheimer’s disease. The study focuses on the anterior cingulate cortex (ACC), a brain region responsible for motivation and emotional regulation, and its interaction with the hippocampus.

ADHD May Raise Dementia Risk

A new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs of nerve damage in ADHD patients compared to healthy individuals.

Changes in Sleep Patterns Could Predict Dementia Risk

A new study finds that women in their 80s who develop increasing daytime sleepiness over five years are twice as likely to develop dementia. Researchers tracked 733 women without cognitive impairment, using wrist devices to monitor sleep and circadian rhythms.

Rubber Hand Illusion Reduces Pain Perception

A new study shows that the rubber hand illusion can reduce the intensity of pain caused by heat. Researchers found that when participants viewed a rubber hand being illuminated while their hidden hand received a heat stimulus, they reported feeling less pain.

Herpes Virus Linked to Long-Term Brain and Neurological Problems

A new study reveals that herpes simplex virus-1 (HSV-1), commonly known for causing cold sores, can travel through the nasal cavity directly to the brain, causing severe and lasting neurological symptoms. In animal experiments, nasal HSV-1 infection led to persistent neurological dysfunction, including anxiety and cognitive impairment.

Nature’s Painkiller: How Virtual Scenes Ease Pain in the Brain

Viewing natural scenes can significantly reduce how people perceive pain, a new neuroimaging study has found. Researchers discovered that participants reported less pain and exhibited altered brain activity associated with pain perception while looking at virtual nature, compared to urban or office environments.

Turn Back Your Brain’s Bioenergetic Clock to Reduce Alzheimer’s Risk

Researchers have discovered that a person's "bioenergetic age," reflecting how efficiently cells produce energy, strongly predicts Alzheimer's risk and progression. High blood levels of molecules called acylcarnitines, markers of aging metabolism, were linked to faster cognitive decline and greater Alzheimer’s symptoms.

Cannabis Terpenes Offer New Hope for Chronic Pain, Fibromyalgia

New research has identified cannabis-derived terpenes—compounds that give plants their distinctive aroma—as effective treatments for fibromyalgia and post-surgical pain. In preclinical mouse models, terpenes such as geraniol and linalool significantly reduced chronic pain, providing promising alternatives to opioid medications and avoiding THC's psychoactive side effects.

Boost Brain Health by Following Your Heart: Simple Steps for Longevity

New research highlights that optimal brain health, crucial for maintaining cognitive function as we age, is strongly linked to cardiovascular wellness. The study underscores that dementia and cognitive decline share risk factors with heart disease, suggesting these conditions are largely preventable by managing diet, exercise, cholesterol, blood sugar, and blood pressure.

How a Common Virus Triggers Brain Attacks in Multiple Sclerosis

New research highlights a critical link between antibodies produced against Epstein-Barr virus (EBV) and the development of multiple sclerosis (MS). Scientists discovered that these viral antibodies mistakenly target a protein called GlialCAM in the brain, triggering autoimmune responses associated with MS.

Genetic Variant in ITSN1 Linked to Higher Parkinson’s and ASD Risk

A new study has identified genetic variants in the ITSN1 gene that significantly increase the risk of developing Parkinson’s disease. Researchers analyzed nearly 500,000 genetic profiles and found that individuals carrying ITSN1 variants face up to a tenfold higher risk of Parkinson’s.
