New symptoms such as failing to identify more than one object at a time and a “space perception deficit” could be the first signs of Alzheimer’s disease, a new study has found.

Posterior cortical atrophy (PCA), is a diagnosis for those who struggle with judging distances, distinguishing between moving and stationary objects and completing tasks like writing and it overwhelmingly predicts Alzheimer’s.

In the latest study from researchers at the University of California, San Francisco, some 94 per cent patients with PCA had Alzheimer’s pathology. Most patients with PCA have normal cognition early on, but by the time of their first diagnostic visit, an average 3.8 years after symptom onset, mild or moderate dementia was apparent with deficits identified in memory, executive function, behavior, and speech and language , according to the researchers’ findings.

A research team at Stanford’s Wu Tsai Neurosciences Institute has made a major stride in using AI to replicate how the brain organizes sensory information to make sense of the world, opening up new frontiers for virtual neuroscience.

A 3D model developed by West Virginia University neuroscientists shows how implantable stimulators—the kind used to treat chronic pain—can target neurons that control specific muscles to provide rehabilitation for people with neurological disorders such as stroke and spinal cord injuries.

A study shows our brains use basic sound rates and patterns to distinguish music from speech, offering insights to enhance therapies for speech impairments like aphasia.

Music and speech are among the most frequent types of sounds we hear. But how do we identify what we think are differences between the two?

Menstruation can often come with a degree of discomfort as the uterus prepares to shed. For some, the effects can be horrendous.

It’s estimated that some 5 to 8 percent of women experience moderate to severe symptoms that have a noticeably negative impact on their lives, mental health, and ability to function normally. These premenstrual disorders, or PMDs, affect millions of women globally, yet we know shockingly little about their long-term consequences.

Now, a new nationwide observational study in Sweden has shown that women with PMDs have an increased risk of suicide. In fact, they’re more than twice as likely to die by suicide as women without PMDs. It’s a sobering figure, one that strongly suggests more work needs to be done to understand PMDs, and help the people who suffer from them.

Swiss startup claims its Neuroplatform is a first for biocomputing.

How can we think about the relationship between the conscious and the physical? In this essay, I wish to propose a way of thinking about it that might be fruitful and surprisingly intuitive, namely to think of consciousness as waves.

The idea is quite simple: one kind of conscious experience corresponds to, or rather conforms to description in terms of, one kind of wave. And by combining different kinds of waves, we can obtain an experience with many different properties in one.
