Study Finds Common Root Cause Behind Multiple Psychiatric Disorders

Health & Fitness /

Researchers recently found that eight psychiatric disorders share a common genetic foundation. A new study has pinpointed specific genetic variants involved, revealing that many remain active longer during brain development. This extended activity suggests they influence multiple developmental stages, making them potential targets for treating multiple conditions. “The proteins produced by these genes are highly

Nasal Fungi May Be Aggravating Your Allergies

Health & Fitness /

Allergic rhinitis and asthma, often linked, can severely impact respiratory health. Searching for better treatments, scientists analyzed the nasal mycobiome—the community of fungi in the nose. Their study revealed that individuals with allergic rhinitis, with or without asthma, have distinct fungal compositions compared to healthy individuals. This suggests chronic respiratory conditions may disrupt nasal fungi

Certain Drugs May Reduce Dementia Risk—A Neuroscientist Explains How

Health & Fitness /

Dementia has no cure, and while some new drugs may slow its progression, they remain expensive and only marginally effective for many. However, a recent Cambridge-led study links commonly used prescription drugs—such as antibiotics, antivirals, and vaccines—to a lower risk of dementia. Since these drugs are already approved with well-known safety profiles, they could fast-track

Could Light Therapy Help Alleviate Alzheimer’s Symptoms?

Health & Fitness /

A new study published in PLOS ONE suggests that light therapy may significantly improve sleep quality, strengthen circadian rhythms, and reduce caregiver burden in Alzheimer’s patients. Alzheimer’s not only impairs memory and cognition but also disrupts sleep and triggers behavioral symptoms like agitation, depression, and aggression. Photobiomodulation, a non-drug therapy that stimulates the brain’s sleep-regulating

Scientists May Have Uncovered How the Brain Renews Itself During Sleep

Health & Fitness /

When you sleep and dream, your brain may undergo a “rinse cycle,” clearing out toxic by-products to prepare for the next day. Researchers from the University of Copenhagen have now mapped the flow of neurotransmitters, blood, and cerebrospinal fluid in mice, uncovering how this process works—and revealing that common sleep drugs like Ambien may disrupt
