Mayo Clinic researchers explore how Alzheimer's disease targets memory-related brain networks

Alzheimer's disease relentlessly targets large-scale brain networks that support the formation of new memories. However, it remains a mystery as to why the disease selectively targets memory-related brain networks and how this relates to misfolded proteins seen by pathologists at autopsy.

Graph theoretical analysis may help predict recovery of motor function after stroke

Graph theoretical analysis is proving to be helpful in understanding complex networks in the brain. Investigators in the Republic of Korea used a graph theoretical approach in examining the changes in the configuration of the two hemispheres of the brain in 12 patients after stroke.

People with intermittent explosive disorder have smaller 'emotional brains'

Neuroimaging studies suggest that frontolimbic regions of the brain, structures that regulate emotions, play an important role in the biology of aggressive behavior.

Naturally occurring changes in brain wiring can help patients avert onset of bipolar disorder

Naturally occurring changes in brain wiring can help patients at high genetic risk of developing bipolar disorder avert the onset of the illness, according to a new study led by researchers at the Icahn School of Medicine at Mount Sinai and published online today in the journal Translational Psychiatry.

Researchers identify biochemical factors that may predict Alzheimer's disease

Investigators have wondered why the brains of some cognitively-intact elderly individuals have abundant pathology on autopsy or significant amyloid deposition on neuroimaging that are characteristic of Alzheimer disease (AD).

Brain regions cause PTSD patients to generalize non-threatening events

Regions of the brain function differently among people with post-traumatic stress disorder, causing them to generalize non-threatening events as if they were the original trauma, according to new research from Duke Medicine and the Durham VA Medical Center.

Understanding the effects of psychotherapy in patients with borderline personality disorder

According to newly published research, a specialized psychotherapy has been linked to changes in activation patterns in certain areas of the brain in patients with borderline personality disorder (BPD), suggesting its impact may go deeper than symptom change.

Neuroscientists find link between neurotransmitter GABA and tactile learning

In an international collaboration with the Johns Hopkins University (Baltimore, MD, USA), neuroscientists at the Ruhr-University Bochum have determined a link between brain levels of the neurotransmitter GABA, the main source of inhibition in the brain, and tactile learning. Using magnetic resonance spectroscopy, they were able to show that success in learning can be predicted by baseline GABA levels.

Older adults who take more steps per day perform better on memory tasks

Could staying physically active improve quality of life by delaying cognitive decline and prolonging an independent lifestyle? A new study has found that older adults who take more steps either by walking or jogging perform better on memory tasks than those who are more sedentary.

Dopamine measurements provides information crucial for human choice

Virginia Tech Carilion Research Institute scientists have reported measurements of dopamine release with unprecedented temporal precision in the brains of people with Parkinson's disease. The measurements, collected during brain surgery as the conscious patients played an investment game, demonstrate how rapid dopamine release encodes information crucial for human choice.

Researchers identify molecular patterns that dominate gene expression in the human brain

The human brain may be the most complex piece of organized matter in the known universe, but Allen Institute researchers have begun to unravel the genetic code underlying its function. Research published this month in Nature Neuroscience identified a surprisingly small set of molecular patterns that dominate gene expression in the human brain and appear to be common to all individuals, providing key insights into the core of the genetic code that makes our brains distinctly human.

ApoE4-carrying men with Alzheimer's disease at risk of brain bleeds

A common genetic variation, ApoE4, linked to Alzheimer's disease greatly raises the likelihood of tiny brain bleeds in some men, scientists have found.

Article explores viewpoints on role of mild cognitive impairment in Parkinson's disease

The current issue of Neurodegenerative Disease Management explores evolving viewpoints on the role of mild cognitive impairment in Parkinson's Disease (PD-MCI), a medical issue which currently lacks consensus. Neurodegenerative Disease Management is published by Future Science Group. The article is also available free of charge to members of Neurology Central, FSG's online community for the international neurology community.
