New MRI technique can ‘see’ molecular changes in brain

Scientists have successfully transformed an MRI from a diagnostic camera into a device that can record changes in the biological makeup of brain tissue. The development will help doctors understand whether a patient is merely aging or developing a neur…

Hearing aids linked to lower risk of dementia, depression and falls

Older adults who get a hearing aid for a newly diagnosed hearing loss have a lower risk of being diagnosed with dementia, depression or anxiety for the first time over the next three years, and a lower risk of suffering fall-related injuries, than thos…

Brain circuit connects feeding and mood in response to stress

An international team has looked into the possibility of crosstalk between eating and mood and discovered a brain circuit in mouse models that connects the feeding and the mood centers of the brain.

Genetic regions associated with left-handedness identified

New research identifies regions of the genome associated with left-handedness in the general population and links their effects with brain architecture. Scientists linked these genetic differences with the connections between areas of the brain related…

Soldiers, athletes could improved outcomes from traumatic brain injuries

A traumatic brain injury is often easily suspected and can be confirmed and treated if necessary following an injury using a blood analysis, but scientists are reporting that even one mild blast to the brain can cause very subtle but permanent damage a…

New insight into motor neuron death mechanisms could be a step toward ALS treatment

Researchers have made an important advance toward understanding why certain cells in the nervous system are prone to breaking down and dying, which is what happens in patients with ALS and other neurodegenerative disorders.

Cannabis may hold promise to treat PTSD but evidence lags behind use

As growing numbers of people are using cannabis to treat post-traumatic stress disorder (PTSD), a new study reports that prescriptions are not backed up by adequate evidence.

Scientists link ‘hunger hormone’ to memory in Alzheimer’s study

Scientists have found evidence suggesting that resistance to the ‘hunger hormone’ ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer’s disease (AD). The findings, based on observations of postmortem br…

Receptor protein in brain promotes resilience to stress

Scientists have discovered that a receptor on the surface of brain cells plays a key role in regulating how both animals and people respond to stress. The research suggests that the receptor may represent an important biomarker of post-traumatic stress…

Wealth can lead to more satisfying life if viewed as a sign of success vs. happiness

A new study found that viewing wealth and material possessions as a sign of success yields significantly better results to life satisfaction than viewing wealth and possessions as a sign of happiness.
