Scientists discover why mental disorders so often overlap

A massive global genetics study is reshaping how we understand mental illness—and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered deep genetic connections across 14 psychiatric condit…

A hidden brain problem may be an early warning for Alzheimer’s

Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some …

A "herculean" genetic study just found a new way to treat ADHD

Attention depends on the brain’s ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by cal…

A key Alzheimer’s gene emerges in African American brain study

Scientists studying Alzheimer’s in African Americans have uncovered a striking genetic clue that may cut across racial lines. In brain tissue from more than 200 donors, the gene ADAMTS2 was significantly more active in people with Alzheimer’s than …

Mini brains reveal clear brain signals of schizophrenia and bipolar disorder

Tiny lab-grown brains are offering an unprecedented look at how schizophrenia and bipolar disorder disrupt neural activity. Researchers found distinct electrical firing patterns that could identify these conditions with high accuracy. The discovery ope…

A surprising brain cleanup reduced epileptic seizures and restored memory

A new study suggests temporal lobe epilepsy may be linked to early aging of certain brain cells. When researchers removed these aging cells in mice, seizures dropped, memory improved, and some animals avoided epilepsy altogether. The treatment used dru…

Scientists found a way to restore brain blood flow in dementia

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing molecule…

Scientists reverse Alzheimer’s in mice and restore memory

Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in adv…

Hidden brain maps that make empathy feel physical

When we watch someone move, get injured, or express emotion, our brain doesn’t just see it—it partially feels it. Researchers found eight body-like maps in the visual cortex that organize what we see in the same way the brain organizes touch. These…

A new drug could stop Alzheimer’s before memory loss begins

New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to dise…
