Antibodies defend the body against bacterial, viral, and other invaders. But sometimes the body makes antibodies that attack healthy cells. In these cases, autoimmune disorders develop.
Immune abnormalities in patients with psychosis have been recognized for over a century, but it has been only relatively recently that scientists have identified specific immune mechanisms that seem to directly produce symptoms of psychosis, including hallucinations and delusions.

Gout appears to have a protective effect for the brain, possibly thanks to uric acid, the chemical in a person's blood that can crystallize, leading to gout, said a team of researchers from north America.
Gout, the most common inflammatory arthritis, is linked to a higher risk of heart and kidney problems and their resulting health issues, but previous studies have theorised that the antioxidant properties of uric acid may protect against the development or progression of neurodegenerative conditions such as Parkinson's disease (PD).

Substantial genetic and moderate environmental influences were associated with risk of autism spectrum disorder (ASD) and broader autism traits in a study of twins in the United Kingdom, according to an article published online by JAMA Psychiatry.
Much of the evidence to date highlights the importance of genetic influences on the risk of autism and related traits. But most of these findings are drawn from samples of individuals which may miss people with more subtle manifestations and may not represent the broader population, according to the study background.

The eyes differ in their optical properties what results in a blur projected in each retina, despite we see sharp images because the visual system calibrates itself. An international research performed by the Consejo Superior de Investigaciones Científicas has discovered that when each eye separately has a different level of blur, our brain uses as sharp reference the image projected through the less aberrated eye. The research has been published in Current Biology.

Like musical sounds, different states of mind are defined by distinct, characteristic waveforms, recognizable frequencies and rhythms in the electrical field of the brain. When the brain is alert and performing complex computations, the cerebral cortex, the wrinkled outer surface of the brain, thrums with cortical band oscillations in the gamma wavelength; in some neurological disorders like schizophrenia, these waves are out of tune and the rhythm is out of sync.

Once upon a time it was believed that greedy insurance companies were bad for patients - now they are a sign of the have's and have nots. A new analysis in Neurosurgery finds that brain tumor patients with private insurance have fewer medical complications and thus are in the hospital less than those who are on Medicaid or were uninsured between 2002 and 2011.

A new review looks at how the brain impacts the sequence of physical and emotional changes that occur as a person participates in sexually stimulating activities.
Experts note that the cerebral cortex region of the brain is involved in all three phases of the sexual pleasure cycle—wanting sex, having sex, and inhibiting sex—and each of these phases depends on distinct networks within the brain. It’s also clear that alterations in these brain networks are associated with sexual dysfunction.
