Medical Daily: Why some people don’t develop bipolar disorder despite high genetic risk

Can we escape from our DNA? Evidence in recent years has led psychiatrists to conclude that bipolar disorder—a mental health disorder characterized by abnormal shifts in mood and energy level—has genetic roots, a notion that could lead us to believe it is unavoidable for those carrying the relevant genes. But new research suggests that our […]

Medical News Today: Bipolar disorder: Brain mechanism could be key for prevention

Scientists have found that many siblings of people with bipolar disorder, who should themselves be susceptible to it, are made resilient by an adaptive brain mechanism, characterized by higher levels of activity in a cerebral network linked with cognition. People with bipolar disorder are subject to extreme mood shifts, from feeling “high” to feeling absolutely […]

News-Medical: How does ADHD affect the brain?

Attention-deficit hyperactivity disorder (ADHD) is a condition characterized by an inability to control one’s attention span so as to effectively complete one activity or cognitive process before proceeding to another. This leads to impulsive decision-making and actions, and typically a hyperkinetic mode of life. (August 18, 2017) Read the full article here

Science Daily: Surprising discovery about how neurons talk to each other

Researchers at the University of Pittsburgh have uncovered the mechanism by which neurons keep up with the demands of repeatedly sending signals to other neurons. The new findings, made in fruit flies and mice, challenge the existing dogma about how neurons that release the chemical signal dopamine communicate, and may have important implications for many […]

Medical News Today: Alzheimer’s could be diagnosed early with sniff tests

Testing the sense of smell of people at a high risk of Alzheimer’s disease might help to provide an early diagnosis, a new study suggests. Alzheimer’s disease is an irreversible condition characterized by memory loss and damage of other cognitive functions. At present, there are no effective ways of diagnosing progression toward Alzheimer’s early on […]

Scientific American: Baby siblings could hold clues to autism diagnosis

In October 2010, Lisa and Eugene Jeffers learned that their daughter Jade, then nearly 2 and a half years old, has autism. The diagnosis felt like a double whammy. The parents were soon engulfed by stress from juggling Jade’s new therapy appointments and wrangling with their health insurance provider, but they now had an infant […]

Cosmos: Adult brain’s fear HQ can grow new cells

A new cradle of brain cell formation has been discovered in the adult amygdala, a region that gives memories their emotional bite. The discovery could lead to a deeper understanding of post-traumatic stress disorder, anxiety, and phobias – and also to better treatments. (August 16, 2017) Read the full article here

UPI: New brain region identified in spatial memory, navigation

Researchers at the Flanders Institute for Biotechnology have identified a new region of the brain responsible for navigation and spatial memory. Patients with Alzheimer’s disease or other neurological conditions have a failure in the specialized neural networks in the brain that are responsible for navigation — leading to memory deficits and disorientation. (August 16, 2017) […]
