One of the most dangerous microorganisms on Earth, Naegleria fowleri has a well-earned nickname as the "brain-eating amoeba," and infection almost always leads to death. Now it's infiltrated the treated drinking water supplied to two Australian towns.

A massive study has found that ADHD medication has a real-world social impact – for the those on the drugs and the wider community. In nearly 150,000 newly diagnosed people, medication appeared to offer sweeping benefits beyond just symptom management.

Just a few days after scientists announced we're at a pivotal tipping point in Alzheimer's disease research, a team has made a huge breakthrough, proving that mitochondrial dysfunction fuels memory loss. Then they engineered a way to restore it.

Some people don't like listening to music. There is nothing wrong with their hearing, but for some strange reason music gives them no pleasure. New research suggests this points to a unique disconnect between the brain’s auditory and reward networks.

Metallic nanoflowers may be the next frontier in brain health, reducing oxidative stress, protecting mitochondria, and even extending lifespan in lab models. A new study shows they hold “incredible potential” as neuroprotective agents.

A green tea extract and vitamin B3 combo may hold the key to reviving the brain’s natural cleanup crew, restoring energy, clearing toxic Alzheimer’s proteins, and giving aging neurons a second wind, according to new research.

A specific amount of the trace element copper has been linked to protecting cognitive function in older adults, providing new insight into how the mineral aids the brain. It may even offer greater benefits to people recovering from stroke.

Scientists have discovered a brain circuit that gives pain its emotional sting, explaining why some hurts linger as suffering. The breakthrough challenges our beliefs about how we process pain and may transform chronic pain treatments.

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 years ago, which would forever change our lives.

A safe and affordable treatment to effectively combat the progress of Parkinson's dementia has emerged – in the form of a commonly available cough syrup that's already being studied for its brain-protecting power in other degenerative diseases.

In a first-of-its-kind study, researchers zoomed in on PTSD at the single-cell level to better understand how it affects the brain. The findings revealed how trauma can lead to specific molecular changes in some brain cells.

Alternating between a calorie-restricted plan and one high in fat and sugar, resulting in weight gain, is not just down to psychology and behavior. This kind of weight-loss-gain cycle – yo-yo dieting – has a surprising biological driver: The gut.
