Traumatic Brain Injury Can Induce Abnormal Tau Protein Deposits

The first evidence has been published that a single traumatic brain injury can generate an abnormal form of the dementia associated protein tau, which can slowly spread through the brain, resulting in memory deficits and neuronal damage. The landmark study comes from the Mario Negri Institute for Pharmacological Research of Milan and the University of…

What Is Novichok? A Neurotoxicologist Explains

Novichok, or “newcomer” in Russian, refers not to a single chemical but rather a group of related molecules designed for only one purpose: to kill. Soviet Scientists applied that nickname to extremely toxic “nerve poisons” developed between the 1970s and 1990s. I am a neurotoxicologist. Since 1980 I have studied how environmental chemicals and toxins…

After Zika Infection, Interferons Drive Fetal Demise

When exposed to Zika virus before birth, mouse fetuses with a specific antiviral protein commit cell suicide, while fetuses without it continued to develop. The finding suggests that the protein, a receptor involved in immune cell signaling, plays a role in spontaneous abortions and other human pregnancy complications. This research could have implications for pregnant…

Bimodal Stimulation May Hold Promise As Chronic Tinnitus Treatment

An experimental device could help suppress tinnitus by targeting rogue nerve activity in the brain, a team from the University of Michigan reports. Based on years of scientific research into the root causes of the condition, the device uses precisely timed sounds and weak electrical pulses that activate touch-sensitive nerves, both aimed at steering damaged…

How Our Brain Helps Us Silence Unwanted Thoughts

An important chemical in the brain’s memory region that enables us to censor unwanted thoughts has been pinpointed by a University of Cambridge study. The finding helps scientists understand why people who suffer from disorders like depression, schizophrenia, post-traumatic stress disorder (PTSD), and anxiety often experience repeated intrusive thoughts when these circuits malfunction. “Our ability…

Adenine DNA Methylation Seen In Stress Response

A novel DNA adenine modification, N(6)-methyladenine (6mA), recently discovered in mammalian cells, has been demonstrated in the mouse brain in response to environmental stress in a study from Emory University. The function of 6mA in the mammalian brain remain unclear. Geneticists at Emory University School of Medicine led by Peng Jin, PhD have been studying…

Does The Lightning Process Help With Chronic Fatigue Syndrome?

People receiving Lightning Process therapy in addition to usual chronic fatigue syndrome care had improved physical function, fatigue and anxiety symptoms, according to a small UK study. The research investigated whether a treatment called the Lightning Process helped teenagers being treated for chronic fatigue syndrome (CFS), also known as ME (myalgic encephalomyelitis). The study randomly…

Tai Chi Reduces Falling Risk For Older Adults

Researchers have compared the effects of tai chi to leg strengthening exercises, a physical therapy called “lower extremity training,” or LET, in reducing falls. Falls are a leading cause of serious injuries in older adults and can lead to hospitalization, nursing home admission, and even death. Arthritis, heart disease, muscle weakness, vision and balance problems,…
