Many long COVID sufferers are reporting having ‘brain fog’, where they can’t concentrate as well as they used to.
Early reports suggested an apparent increase in OCD relapse rates and symptom severity during the pandemic. But a year on, we’re learning this may not be the case.
Different MR images help us unravel the mysteries of the brain. A diffusion MRI tractography reconstruction like this reveals the complicated wiring deep within a person’s brain.
Odd findings in a brain scan of a 29-year-old woman have scientists asking new questions about how our sense of smell really works.
A headache is not from your brain itself hurting, but it might mean some of the muscles, membranes and tissues surrounding the brain or its blood supply system could be hurting.
The brain itself can’t actually feel pain. It can’t sense damage to itself the way your finger can. We know this because people can have brain surgery while they are totally awake.
Your brain is about 70% water.
An adult brain weighs about 1.5kg. It’s mostly water with some fat, protein, sugar and a dash of salt. Sounds like pancakes, I know, but I once tried chicken brains and, well, pancakes are tastier.
Les personnes exposées à un faible ensoleillement et les femmes sont plus susceptibles d'être atteintes de sclérose en plaques.
La sclérose en plaques affecte de façon surtout les jeunes femmes. Elle survient quand le système immunitaire attaque le cerveau et brouille la communication avec le corps. Quelles sont ses causes ?
Las personas expuestas a bajos niveles de luz solar tienen más probabilidades de padecer esclerosis múltiple que las que viven en climas cálidos.

Las mujeres jóvenes son mucho más propensas a padecer esclerosis múltiple, una enfermedad en la que el cuerpo ataca al cerebro, dificultando la comunicación con el resto del organismo. Esto es lo que sabemos sobre las causas.
People exposed to low levels of sunlight are more likely to have MS than those who live in warm climates.
Young women are disproportionately affected by multiple sclerosis, a disease where the body attacks the brain, scrambling communication to the rest of the body. Here’s what we know about the causes.
Thinking ability declines with age in those with dementia.
Have you noticed your thinking ability drops during winter and spring? A new study of healthy adults and dementia patients found cognitive function declines in the colder months.
The fashion advice is generally to tighten ties so they’re tight but not too tight.
Wearing a tie that causes slight discomfort can reduce blood flow to the brain by 7.5%, but the reduction is unlikely to cause any physical symptoms, which generally begin at a reduction of 10%.
Lifestyle factors such as meditation can change our brain for the better.
How can exercise, meditation and hypnosis change our brains and potentially prevent disease?
Statistics has Guinness to thank for the Student’s t-test.
A statistical method widely used today by scientists and others is all thanks to a statistician at a Guinness brewery whose work was published anonymously more than a century ago.
A hallmark of Alzheimer’s disease is gradual deterioration of memory.
Alzheimer’s disease is the most common form of dementia, but treatments are still far from successful in clinical trials. Here is what we know about the disease, and what is yet to be uncovered.
Why do we retain some memories better than others?

The Florey Institute’s Dr Jee Hyun Kim explains how the different aspects of memory work and why attention is the most important element of improving your memory in this long-form comic explainer.
The pathway from eye to brain begins in the retina, where light is converted into neuronal signals.
Light arriving from the right visual field is processed in the brain’s left hemisphere. So damage to the left part of the primary visual cortex will result in blindness in the right visual field.
Our mood is a transient frame of mind that influences how we think and view the world.
Many regions fundamental to mood are buried deep in the most primordial parts of the brain; that is, they are thought to have been among the first brain regions to develop in the human species.
Our language abilities are enabled by a co-ordinated network of brain regions that have evolved to give humans a sophisticated ability to communicate.
When you read this text, certain regions in your brain begin working more than others. Advanced imaging allows scientists to map the brain networks responsible for understanding language.
Success in human drug development is painfully low.
News reports this week hailing a breakthrough in Alzheimer’s research, saying a vaccine for the disease is a few years away, have raised hopes for many. But let’s take a step back from the headlines.
Motor symptoms of Parkinson’s include tremors, stiffness and slowness or loss of spontaneous movement.
Parkinson’s disease is the second-most-prevalent neurodegenerative condition in Australia, with an estimated 70,000 living with the disease. But what do we know about the causes and risk factors?
The health sector can learn from other industries that turn to operations research to fix everyday challenges.
Fixing the hospital system is not just a matter of more funding. Hospitals need to work smarter, not harder.
