Anxiety may accelerate the progression of mild cognitive impairment to Alzheimer's disease. Brain scans revealed patients who progressed from MCI to Alzheimer's disease had decreased volume in the hippocampus and entorhinal cortex. Read More
Pnoc neurons in the BNST trigger pupillary response and increase heart rate in response to anxiety and fear. Read More
Study identifies inflammatory mechanisms and cellular activity in the amygdala that drives alcohol addiction in mice. Chronic alcohol exposure compromises immune cells in the brain, driving anxiety and alcohol consumption that may lead to the development of AUD. Read More
Overactivity in the subgenual anterior cingulate cortex underlies several key symptoms of depression, anxiety, and heart disease. Read More
Male and female rodents exhibit distinct symptoms and brain features of both PTSD and alcohol use disorder. Following trauma, males show increased GABA receptor function, while females showed increased GABA release. Read More
Fear and anxiety share overlapping neural circuits. The findings contradict the popular belief that anxiety and fear are distinct emotions with different triggers and segregated brain circuits. Read More
Oxytocin produced in the BNST increased stress-induced social anxiety behaviors in mice. The findings shed light on why oxytocin can sometimes provoke anti-social effects. Read More
The ability to foster and form secure interpersonal attachments can mitigate some of the genetic risks associated with PTSD. Read More
New studies reveal COVID-19 is having a negative impact on sleep, spurring dreams that cause anxiety and emotional upset. Women appear to experience more disturbing dreams than men. Read More
Older people who have higher levels of neuroticism are more likely to have worse cognitive function than those with other personality traits. Researchers say personality traits may be related to how well people can maintain their cognitive function, despite developing neuropathology associated with aging and dementia. Read More
Older adults who took brief, weekly "awe walks" for eight weeks reported improvements in positive emotions and a decrease in daily life stress. Read More
Study provides contrary evidence to existing theory, finding anxiety and fear reflect overlapping neural circuits. Read More
