Older adults share fewer memories as they age
June 29, 2020
Researchers used a smartphone app to 'eavesdrop' on older adult conversations. They found that the older a person is, the less likely they are to share memories of past experiences.
Plasticity may make neurons vulnerable to Alzheimer’s disease
June 29, 2020
Neurons that regularly remodel are more prone to the dysfunctions linked to the disease's onset, a new experimental and computational study finds.
New research paves way for developing therapies that could slow down Alzheimer’s
June 29, 2020
Neuroscientists and stem cell researchers have developed a research model that allows studying human hippocampal neurons, the brain cells primarily affected by Alzheimer's disease pathology.
Why some words may be more memorable than others
June 29, 2020
In a recent study of epilepsy patients and healthy volunteers, researchers found that our brains may withdraw some common words, like ''pig,'' ''tank,'' and ''door,'' much more often than others, including ''cat,'' ''street,'' and ''stair.'' By combining memory tests, brain wave recordings, and surv...

Repeated head impacts associated with later-life depression symptoms, worse cognitive function
June 26, 2020
In the largest study of its kind, an association has been found in living patients exposed to repetitive head impacts and difficulties with cognitive functioning and depression years or decades later.
Designer peptides show potential for blocking viruses, encourage future study
June 26, 2020
Chemically engineered peptides could prove valuable in the battle against some of the most persistent human health challenges. New findings demonstrate how researchers can engineer peptides capable of selectively and specifically binding to polysialic acid (PSA) -- a carbohydrate that is present in ...

Scientists devise new ‘bar code’ method to identify critical cell types in the brain
June 25, 2020
A discovery could pave the way for future studies aimed at developing solutions to ALS and other vexing neuromuscular diseases.
New study looks at post-COVID-19 emerging disease in children
June 25, 2020
In recent weeks, a multisystem hyperinflammatory condition has emerged in children in association with prior exposure or infection to SARS-CoV-2. A new case series examines the spectrum of imaging findings in children with the post-COVID-19 inflammatory condition known in the US as Multisystem Infla...

One-time treatment generates new neurons, eliminates Parkinson’s disease in mice
June 25, 2020
Researchers have discovered that a single treatment to inhibit a gene called PTB in mice converts native astrocytes, brain support cells, into neurons that produce the neurotransmitter dopamine. As a result, the mice's Parkinson's disease symptoms disappear....

Unexpected mental illnesses found in a spectrum of a rare genetic disorder
June 25, 2020
Researchers found an unexpected spectrum of mental illnesses in patients with a rare gene mutation. These patients had a ''double hit'' condition that combined features and symptoms of fragile X syndrome and premutation disorder, in addition to a range of psychiatric symptoms. The findings revealed ...
