Scientists create new map of brain region linked to Alzheimer’s disease

Scientists have now completed an exceptionally detailed map of the brain’s memory bank, the hippocampus. Intricate insight into hippocampus’ structure and function opens new opportunities to treat diseases such as Alzheimer’s.

Previously unknown genetic aberrations found to be associated with Alzheimer’s progression

Researchers present a comprehensive genome-wide map of RNA splicing variation in the aging brain. The novel insights could offer new strategies for diagnosis and treatment of Alzheimer’s disease.

Club drug GHB associated with brain and cognitive changes

Scientists have discovered that regular use of the party drug GHB, and especially unconsciousness following GHB use, is associated with brain changes including negative effects on long-term memory, working memory, IQ, and higher levels of stress and an…

Pregnant women recognize baby expressions differently depending on mental health history

A pilot study has found that pregnant women who have suffered from depression or bipolar disorder (i.e. both mania and depression) recognize babies’ faces and how babies laugh or cry, differently to healthy controls. This happens even if they are not c…

Gene which decreases risk of social network-related stress, increases finance-related stress risk

Researchers have discovered that the same gene which increases your risk of depression following financial stress as you grow older also reduces your chance of depression associated with friendship and relationships stresses when young- your social net…

‘Winter blues’ study finds key to depression resilience

A new study examines the brains of people with seasonal affective disorder to examine why some people do not develop depression despite being at risk.

Tourette’s syndrome: 400 genetic mutations found

New research sheds light on the possible genetic causes of Tourette’s syndrome and the brain development disruptions that characterize the condition.

A new take on the 19th-century skull collection of Samuel Morton

After unearthing and analyzing handwritten documentation from scientist Samuel Morton, a doctoral candidate drew a new conclusion about the infamous 19th-century collection: though Morton accurately measured the brain size of hundreds of human skulls, …

Every cell has a story to tell in brain injury

Traumatic head injury can have widespread effects in the brain, but now scientists can look in real time at how head injury affects thousands of individual cells and genes simultaneously in mice. This approach could lead to precise treatments for traum…

Periodontal disease bacteria may kick-start Alzheimer’s

Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer’s disease in humans. Periodontal disease may be an initiator of Alzheimer’s.
