As they go about their everyday lives, people often have to choose between a safe option and a riskier one, such as staying in a secure job, or starting a … Continue Reading Study identifies neural circuits involved in making risky decisions.
Scientists have long speculated that schizophrenia, which affects about 1 in every 100 adults worldwide, originates in part in the hippocampus, the brain’s headquarters for memory and spatial navigation. As … Continue Reading Schizophrenia linked to loss of cells in brain’s memory centre for the first time.
Internet gaming disorder (IGD) is defined as a failure to control one’s impulses to excessively use online gaming. IGD results in serious negative outcomes, such as decreased physical and mental … Continue Reading Neuroimaging identifies brain differences in compulsive video game players.
Antidepressants are recommended as a first-line treatment of severe depression and for the treatment of mild-to-moderate depression that persists after conservative measures such as cognitive therapy. Experts recommend against their … Continue Reading Study maps structural brain changes caused by antidepressants.
Synapses are specialized, protein-rich cell junctions that are essential for normal brain function and are dysfunctional in many diseases and disorders of the nervous system. Synapses are made up of … Continue Reading Study identifies elusive master regulator of synaptic protein sorting.
A new study by researchers from Wayne State University, University of Toronto and University of Michigan demonstrates that communication between some of the brain’s most important centres is altered in … Continue Reading Neuroimaging study of brain networks maps differences in children with OCD.
DNA sequences were once thought to be identical from cell to cell, but it’s increasingly understood that mutations can arise during brain development that affect only certain groups of brain … Continue Reading New single-cell sequencing technique can track subtle neurogenetic mutations spatially.
Schizophrenia is generally considered to be a disorder of brain development and it shares many risk factors, both genetic and environmental, with other neurodevelopmental disorders such as autism and intellectual … Continue Reading Scientists begin to map neurodevelopment of schizophrenia.
A neuroimaging study involving 750 children and teens reveals a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without. Children with ADHD, a new … Continue Reading Neuroimaging study finds slower development of connections in children with ADHD.
A new class of compounds has now been shown to protect brain cells from the type of damage caused by blast-mediated traumatic brain injury (TBI). Mice that were treated with … Continue Reading Compound protects brain cells after traumatic brain injury.
The same sex hormone that helps protect females from stroke may also reduce their risk of autism, scientists say. In the first look at a potential role of the female … Continue Reading Estrogen receptor expression may help explain why more males have autism.
Scientists at the University of Warwick have provided the first evidence that the lack of a naturally occurring protein is linked to early signs of dementia. The research found that … Continue Reading Lack of naturally occurring protein linked to dementia.
Howard Hughes Medical Institute (HHMI) scientists have developed a strategy for finding disease-causing mutations that lurk in only a small fraction of the body’s cells. Such mutations can cause significant … Continue Reading New gene technique identifies hidden causes of brain malformation.
Researchers have long suspected that major mental disorders are genetically-rooted diseases of synapses, the connections between neurons. Now, investigators from Johns Hopkins University have demonstrated in patients’ cells how a … Continue Reading Suspect gene corrupts neural connections.
A new study from the University of Lubeck identifies a novel gene that controls nerve conduction velocity. Investigators report that even minor reductions in conduction velocity may aggravate disease in multiple … Continue Reading Gene that controls nerve conduction velocity linked to multiple sclerosis.
Two years ago, the parents of Chloe Olivarez watched painfully as their daughter experienced epileptic seizures hundreds of times a day. The seizures, caused by a rare metabolic disease that … Continue Reading Precursor reduces debilitating epileptic seizures.
