Drug May Blunt Neurological Damage Caused by Liver Failure

Drug May Blunt Neurological Damage Caused by Liver Failure

Individuals with impaired liver function are unable to remove ammonia – a by-product of normal cellular activity – from their bodies fast enough.  This result is a host of neurological problems, including seizures, for which doctors have no effective treatment.  A new study shows that an existing blood pressure drug may be able to prevent the molecular chain reaction in the brain triggered by ammonia. 

Study Links Menstrual Cycle, Concussion Outcomes in Women

Study Links Menstrual Cycle, Concussion Outcomes in Women

Researchers found that women injured during the two weeks leading up to their period (the premenstrual phase) had a slower recovery and poorer health one month after injury compared to women injured during the two weeks directly after their period or women taking birth control pills.

A Good Night’s Sleep Really Does ‘Clear the Mind’

A Good Night’s Sleep Really Does ‘Clear the Mind’

Why do we sleep?  It is a question that has long puzzled scientists and philosophers alike.  While the ancient Greeks saw sleep as a doorway to the divine, scientists and biologists see it as an invitation to be devoured by nocturnal predators.  A new study – appearing today in the journal Science – may provide the answer: when we sleep our brain ‘takes out the trash.’

New Concussion Data:  Two Biomarkers Better Than One

New Concussion Data: Two Biomarkers Better Than One

Scientists are scrambling to gather data for the FDA to support the need for a blood test to diagnose brain injury in the United States. The University of Rochester Medical Center just added significant evidence by reporting in the Journal of Neurotrauma that it might be clinically useful to measure two brain biomarkers instead of one.

Copper Key Contributor to Alzheimer’s

Copper Key Contributor to Alzheimer’s

Copper is ubiquitous in the food supply and drinking water.  In the right amounts, it helps the body perform many important functions.  However, a new study points to the metal’s darker side: too much copper can accumulate in the brain and contribute to the buildup of toxic proteins that cause Alzheimer’s disease.
