A new study has discovered profound abnormalities in brain activity in a group of retired American football players.  Although the former players in the study were not diagnosed with any neurological condition, brain imaging tests revealed unusual activity that correlated with how many times they had left the field with a head injury during their careers.

In the largest ever study of migraines, researchers have found five genetic regions that for the first time have been linked to the onset of migraine. This study opens new doors to understanding the cause and biological triggers that underlie migraine attacks.

Disorders such as schizophrenia can originate in certain regions of the brain and then spread out to affect connected areas. Identifying these regions of the brain, and how they affect the other areas they communicate with, would allow drug companies to develop better treatments and could ultimately help doctors make a diagnosis. But interpreting the vast amounts of data produced by brain scans to identify these connecting regions has so far proved impossible.

Brain-computer interfaces are at the cutting edge for treatment of neurological and psychological disorder, including Parkinson's, epilepsy, and depression. Among the most promising advance is deep brain stimulation (DBS) — a method in which a silicon chip implanted under the skin ejects high frequency currents that are transferred to the brain through implanted electrodes that transmit and receive the signals. These technologies require a seamless interaction between the brain and the hardware.

Studies suggest that neurotrophic factors, which play a role in the development and survival of neurons, have significant therapeutic and restorative potential for neurologic diseases such as Huntington's disease. However, clinical applications are limited because these proteins cannot easily cross the blood brain barrier, have a short half-life, and cause serious side effects. Now, a group of scientists has successfully treated neurological symptoms in laboratory rats by implanting a device to deliver a genetically engineered neurotrophic factor directly to the brain.

A new family of six genes that regulate the movement and position of mitochondria in neurons described by University of Barcelona scientists. It is a cluster of six genes that may be altered in neurological conditions, such as Parkinson’s and Charcot-Marie-Tooth disease, which are caused by alterations of genes that control mitochondrial transport, a process that provides the energy required for cell function.
