New technology allows researchers to produce images that predate the formation of amyloid beta in the brain. The findings have prompted researchers to suggest stabilizing the protein, rather than attempting to limit it, in order to reduce Alzheimer’s symptoms.

new study shines light on the process by which head injuries lead to brain disease later in life. 

A new type of long-term potentiation that is controlled by kainate receptors has been reported by scientists. The finding could have major benefits to understanding how the brain works and what goes wrong in neurodegenerative disorders such as epilepsy and dementia.

According to researchers, axons coordinate each other’s destruction, contributing to neurodegeneration.

Dendrites are not just passive conduits, a new study reports. The finding could change scientists’ understanding of how the brain works, and lead to new approaches for treating neurological disorders.

Structural differences have been found in the cerebral cortex of patients with depression, and these differences normalize with appropriate medication,  a new study reports.

Researchers at Karolinska Institutet collaborating in the large-scale Karolinska Schizophrenia Project are taking an integrative approach to unravel the disease mechanisms of schizophrenia. In the very first results now presented in the prestigious scientific journal Molecular Psychiatry, the researchers show that patients with schizophrenia have lower levels of the vital neurotransmitter GABA as well as changes in the brain’s immune cells.

Finally this week, researchers have identified a genetic variant that can accelerate normal brain aging in older people by up to 12 years.
