‘Growth charts’ for cognitive development may lead to earlier diagnosis, treatment for children with risk for psychosis

Researchers have developed a better way to assess and diagnose psychosis in young children. By “growth charting” cognitive development alongside the presentation of psychotic symptoms, they have demonstrated that the most significant lags in cognit…

How chronic stress predisposes brain to mental disorders

Biologists have shown in rats that chronic stress makes stem cells in the brain produce more myelin-producing cells and fewer neurons, possibly affecting the speed of connections between cells as well as memory and learning. This could explain why stre…

Excess weight linked to brain changes that may relate to memory, emotions, and appetite

Being overweight appears related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control, according to a new study.

What makes older people happy?

As people age and become more settled, ordinary experiences become central to a sense of self and therefore more valued and satisfying.

Coping with a problem ‘child’ at the office

Aging and the pursuit of happiness

As human beings, we expend a great deal of time, money, and energy in the pursuit of happiness. From exotic travel to simply spending time with our grandchildren, the things that make us happy change as we age. A new study explores the role of age on t…

Males and females differ in specific brain structures

Reviewing over 20 years of neuroscience research into sex differences in brain structure, researchers have conducted the first meta-analysis of the evidence. The team performed a quantitative review of the brain imaging literature testing overall sex d…

Lactate and brain function: How the body regulates fundamental neuro-hormone

New research has revealed a previously unknown mechanism in the body which regulates a hormone that is crucial for motivation, stress responses and control of blood pressure, pain and appetite. The breakthrough could be used to design drugs to help fig…

Scientists identify gene linking brain structure to intelligence

For the first time, scientists have identified a gene linking the thickness of the grey matter in the brain to intelligence. Teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere, particularly in the frontal …

How our brain networks: White matter ‘scaffold’ of human brain revealed

For the first time, neuroscientists have systematically mapped the white matter “scaffold” of the human brain, the critical communications network that supports brain function.
