As plaque deposits increase in the aging brain, money management falters

Older adults who experience problems completing simple financial tasks, such as calculating their change, may be at increased risk of Alzheimer's disease. Problems with financial management have often been associated with later stage dementia. A new study reveals this could be one of the earliest signs of dementia and may be correlated with a build-up of amyloid plaque deposits.

Newly discovered mechanism reveals how Parkinson’s disease can spread between brain cells

Connexins play a critical role in the uptake and transfer of Parkinson's related proteins from one cell to another. The findings may help with the development of new treatments for Parkinson's disease.

Does your health in middle age predict how healthy you’ll be later in life?

Vascular and inflammatory problems during middle age, as well as some minor injuries, could be a biomarker for poor brain health in older age. However, brain aging may be delayed by maintaining a healthy diet, weight and level of physical activity as we age.

Brain stimulation enhances visual learning speed and efficiency

Transcranial random noise stimulation (tRNS) helps boost visual learning in patients with chronic cortical blindness, leading to a recovery in motion processing within 10 days of exposure. The effects of the tRNS treatment appear to last for at least six months.

How stress leads to Facebook addiction

Stress can have an impact on how we utilize social media sites like Facebook. Those who use the social network to facilitate social support during times of stress are more susceptible to developing Facebook addiction disorder.

‘Mindreading’ neurons capable of having expectations about the behavior of the others

Simulation neurons found in the amygdala allow animals to reconstruct the mental state of social partners and predict intentions. Dysfunction in these newly identified neurons may be involved in disorders associated with social behavioral problems, such as autism and social anxiety.

High LDL cholesterol linked to early-onset Alzheimer’s

Elevated levels of LDL cholesterol has been linked to an increased risk of early-onset Alzheimer's disease, in those with and without a genetic risk factor. This suggests cholesterol could be an independent risk factor for dementia. Additionally, researchers identified a potential new genetic risk factor for early-onset Alzheimer's, a rare variant of the APOB gene.

Altered Brain Activity in Antisocial Teenagers

Neuroimaging reveals lower activation in the dorsolateral prefrontal cortex and angular gyrus in teenage girls with conduct disorder. Findings suggest that a reduction in prefrontal brain regions and functional connectivity during effortful emotional regulations contribute to behaviors associated with antisocial behavior in teenage girls.

Broken brain cells repaired in dementia mouse model

Chemically activating neurons and placing mice in stimulating environments reverses alterations and restores some neural connectivity in frontotemporal dementia. If translated into humans, the findings could help develop new treatments for fighting the effects of dementia in the elderly.
