U.S. News & World Report: Good news, bad news on levodopa for parkinson’s disease

The most potent drug available for Parkinson’s disease, levodopa, treats symptoms of the disease but does nothing to either ease or increase its still-mysterious underlying causes, a new clinical trial has concluded. Doctors often delay prescribing levodopa, or L-dopa, to Parkinson’s patients for fear that the drug might have toxic effects that produce jerky involuntary […]

Medical Xpress: The price we pay for our advanced brains may be a greater tendency to disorders

Prof. Rony Paz of the Weizmann Institute of Science suggests that our brains are like modern washing machines—evolved to have the latest sophisticated programming, but more vulnerable to breakdown and prone to develop costly disorders. He and a group of researchers recently conducted experiments comparing the efficiency of the neural code in non-human and human […]

Futurity: Brain biomarkers may explain severe PTSD

Researchers have discovered biomarkers that may explain why symptoms of post-traumatic stress disorder can be so severe for some people and not for others. The study of combat veterans who have experienced intense events shows that those with severe symptoms of PTSD have distinct patterns of neurological and physiological responses affecting associative learning—the ability to […]

Medical News Today: Alzheimer’s: What leads to brain cell damage?

Scientists have uncovered a mechanism through which a toxic brain protein that is a hallmark of Alzheimer’s disease can damage neurons, or brain cells. The team at the Grenoble Institute of Neurosciences in France that made the discovery also suggests a potential way to disarm the mechanism during the early stages of the disease. (January […]

New Atlas: Brain implant shows promise for stopping seizures

There may be new hope for people who suffer from epilepsy. A recent study has shown that an experimental implant reduces seizures in epileptic rats by 93 percent, and that the effects remain after the device has been removed. (January 21, 2019) Read the full article here

News-Medical: Unexpected connection found between feeding and memory centers of the brain

The search for a mechanism that could explain how the protein complex NCOR1/2 regulates memory has revealed an unexpected connection between the lateral hypothalamus and the hippocampus, the feeding and the memory centers of the brain, respectively. The findings, which were published today in the journal Nature Neuroscience by a multidisciplinary team led by researchers […]

Spectrum: Sibling study bolsters genetic link between autism, attention deficit

Children who have an older sibling with attention deficit hyperactivity disorder (ADHD) are at an increased risk of having autism, a new study suggests. The reverse is also true. Autism and ADHD share some features and often co-occur. Other studies have documented the increased risk in siblings for each of the conditions individually. (January 21, […]

Medical News Today: Key brain area plays a crucial role in addiction

New research finds that the cerebellum, a large part of the human brain that scientists thought was primarily involved in motor control, may play a key role in reward-seeking and social behaviors. The findings may help inform future therapies for treating addiction. (January 19, 2019) Read the full article here

Science Daily: ‘Happiness’ exercises can boost mood in those recovering from substance use disorder

Brief, text-based, self-administered exercises can significantly increase in-the-moment happiness for adults recovering from substance use disorders, report researchers at the Massachusetts General Hospital (MGH) Recovery Research Institute. The study, published online in the Journal of Substance Abuse Treatment, is the first of its kind to test whether positive psychology exercises boost happiness in persons recovering […]
