Why Some Words May Be More Memorable than Others

Some words are far more memorable than others. Researchers discovered our memories are wired into neural networks that allow the brain to search for these memories, much like the way search engines track down relevant information. Read More

APOE4 triggers early breakdowns in the blood-brain barrier

APOE4, a gene implicated as a risk factor for Alzheimer's disease, triggers leaks in the blood-brain barrier. The damage to capillaries APOE4 causes correlates with increased levels of cyclophilin, a protein that causes the inflammation that is a signature of early Alzheimer's. Read More

New Year’s anxiety hangover? Here’s what’s happening in your brain

Hangxiety, the feeling of waking up with anxiety the morning after heavy drinking, is a common symptom associated with a hangover. Researchers explain how a heavy night's drinking alters neurochemistry, leaving some of us prone to waking with anxiety. Read More

The brain’s pathways to imagination may hold the key to altruistic behavior

Imagination helps us act altruistically, a new study reports. When we see others in trouble, we imagine how we can help before acting. Researchers implicate the medial temporal lobe subsystem in guiding our prosocial behaviors. Read More

Brain changes linked with Alzheimer’s up to 30 years before symptoms appear

Researchers have identified average levels of biological and anatomical brain changes associated with Alzheimer's disease over thirty years before symptoms appear. In those with genetic risk factors for Alzheimer's, researchers found changes in cognitive performance up to 15 years before becoming symptomatic. Changes in Tau levels in the cerebral spinal fluid appeared up to 34 years before dementia symptoms occurred, and physical changes to the medial temporal lobe were apparent up to 9 years before cognitive impairment was apparent.

When is Alzheimer’s not Alzheimer’s? Researchers characterize a different form of dementia

LATE, a form of dementia that appears in the oldest-old is often mistaken for Alzheimer's disease, but the brain pathology is very different. The protein TDP-43 appears to play a significant role in the development of LATE. The neurodegenerative disease may progress more gradually than Alzheimer's, but when combined with Alzheimer's disease (a common combination), appears to cause a more rapid decline than either would alone.

New Insight on How Memory Works

Study reports declarative memory depends upon conscious knowledge of what has been previously learned. Researchers discovered conscious knowledge is compromised in those with damage to the hippocampus. The findings shed new light on how the hippocampus controls the process of memory. Read More
