A 60-year-old woman from China gradually lost her ability to communicate with her surroundings after suffering for about two months from deteriorating thinking and behavioral changes, until she stopped speaking completely. At the Qilu Hospital in Jinan, doctors tried to understand what was behind her condition, and after a series of tests, it turned out that her immune system had begun to...

We all know that moment: a small comment from a partner sets us off, or a routine traffic jam causes a sudden wave of rage. Sometimes it feels like anger comes out of nowhere, and it can be very exhausting and confusing.

Depression is often perceived as a mood disorder, but a new study adds evidence that associated changes may reach the level of brain cells. Researchers found that in people suffering from depression, there are disruptions in the process of creating new nerve cells in the hippocampus, a brain region linked to memory and emotion.

Have you always wondered why after a long day it is simply impossible to keep your eyes open? A new study has identified groups of cells in the brain that measure the time we are awake - creating pressure - and forcing us to sleep. The researchers: "May reveal ways to provide resistance to sleep deprivation and other physiological challenges."

Researchers have identified previously unknown immune structures within the skull bone marrow that act as a local brain defense center. The study, published in Nature, could lead to new treatments for brain tumors and neurological conditions.

You are sitting in a place you have never been, having a conversation you have never had, and suddenly it happens: a strong and strange feeling takes hold of you — "I have been here before." "I have already heard this sentence." "I know this moment." But when you try to remember when it happened, you have no answer. You know the moment is new, yet the brain sends you a completely opposite feeling...

There are moments when something just feels wrong. We have no explanation, no clear fact to point to, and yet something inside signals us to stop. Sometimes the feeling turns out to be surprisingly accurate, and sometimes we realize it misled us completely.

The adult brain may possess a greater capacity for repair than previously thought. In a new study published Wednesday, researchers from the University of Zurich identified special cells in mice that mobilize following brain injury to restore damaged tissue.

An unusual medical case in the Philippines highlights the environmental risks following natural disasters: a 52-year-old woman was hospitalized with severe neurological symptoms. Scans revealed pork tapeworm larvae in her brain tissue, contracted due to poor sanitary conditions.

A test lasting about a quarter of an hour may in the future provide doctors with objective information about brain activity and assist in the diagnosis of a long list of neurological and psychiatric disorders. The Israeli NeuroAI company Hemispheric is developing an artificial intelligence system designed to "decode" the brain's electrical signals—a field where diagnosis still relies in many cases...

We tend to think that a forgotten memory is like a file permanently deleted from a computer, but scientists have discovered that reality is much more complex. A new study published in the scientific journal Nature Neuroscience shows that in fruit flies, memories we thought had disappeared completely actually remain hidden deep in the brain, ready to come to life as soon as we receive the right...

A large study recently published reached an optimistic conclusion: 70 and 80-year-olds can improve their cognitive abilities just like young people. However, the promise is controversial: do brain training exercises really improve overall brain function, or does the key lie elsewhere? On one thing everyone agrees: the perception that the brain necessarily deteriorates over time is no longer...

For millions of people, preparing for sleep involves using white noise. We explore why the brain needs background sounds to mask disturbances and how different noise colors affect sleep.

A new study, conducted on mice, shows that in adolescence, not only are unnecessary connections between nerve cells removed, but new communication centers are created — the absence of which may be related to the development of diseases like schizophrenia.
