• Researchers propose novel new treatment of stroke, other neurological diseases

  02-03-2015 18:33
  
  Medicine should reconsider how it treats stroke and other neurological disorders, focusing on the intrinsic abilities of the brain and nervous system to heal themselves rather than the 'modest' benefits of clot-busting drugs and other neuroprotective treatments, experts suggest.

• Low sugar uptake in brain appears to exacerbate Alzheimer's disease

  02-03-2015 18:31
  A deficiency in the protein responsible for moving glucose across the brain's protective blood-brain barrier appears to intensify the neurodegenerative effects of Alzheimer's disease, according to a new mouse study. The research suggests that targeting the protein called GLUT1 could help prevent or slow the effects of Alzheimer's, especially among those at risk for the disease.

• Scientists crack piece of neural code for learning, memory

  02-03-2015 18:31
  
  Researchers describe how postmortem brain slices can be 'read' to determine how a rat was trained to behave in response to specific sounds, a new article suggests. The work provides one of the first examples of how specific changes in the activity of individual neurons encode particular acts of learning and memory in the brain.

• Cerebral blood flow as a possible marker for concussion outcomes

  02-03-2015 18:31
  Cerebral blood flow recovery in the brain could be a biomarker of outcomes in patients following concussion, a new imaging study suggests. Most of the 3.8 million sports-related traumatic brain injuries (TBIs) that occur annually are concussions. Developing methods to diagnose the presence and severity of concussions is imperative, the authors say.

• Results challenge conventional wisdom about where the brain begins processing visual information

  02-03-2015 18:16
  
  Neuroscientists generally think of the front end of the human visual system as a simple light detection system: The patterns produced when light falls on the retina are relayed to the visual cortex at the rear of the brain, where all of the "magic" happens that transforms these patterns into the three-dimensional world view that we perceive with our mind's eye. Now, however, a brain imaging study challenges this basic assumption.

• Sleep-walking neurons: Brain's GPS never stops working -- even during sleep

  02-03-2015 18:15
  
  Navigational brain cells that help sense direction are as electrically active during deep sleep as they are during wake time, scientists have discovered. Such information could be useful in treating navigational problems associated with Alzheimer's disease and other neurological disorders.

• Insulin resistance in the brain, behavioral disorders: Direct link found

  02-03-2015 18:15
  People with diabetes are more prone to anxiety and depression than those with other chronic diseases that require similar levels of management. Genetically modifying mice to make their brains resistant to insulin, scientists first found that the animals exhibited behaviors that suggest anxiety and depression, and then pinpointed a mechanism that lowers levels of the key neurotransmitter dopamine in areas of the brain associated with those conditions.

• Brain metastases: Better outcomes for those under 50 years old receiving stereotactic radiosurgery alone

  02-03-2015 16:45
  Cancer patients with limited brain metastases (one to four tumors) who are under 50 years old should receive stereotactic radiosurgery (SRS) without whole brain radiation therapy (WBRT), according to a study.

• Long-term care may not be best for adults with traumatic brain injury; other housing needed

  02-03-2015 16:45
  A new, large-scale Canadian study shows that many adults with traumatic brain injury (TBI) live in a long-term health setting – such as a nursing home- which may not be appropriate for their condition and younger age.

• New target identified in fight against Alzheimer's, multiple sclerosis

  02-03-2015 15:16
  
  Highlighting a potential target in the treatment of multiple sclerosis (MS) and Alzheimer’s disease, new research suggests that triggering a protein found on the surface of brain cells may help slow the progression of these and other neurological diseases.

• Alzheimer amyloid clumps found in young adult brains

  02-03-2015 13:13
  Amyloid -- an abnormal protein that's a hallmark of Alzheimer's -- starts accumulating inside neurons of people as young as 20, reports a study. This is the first time amyloid accumulation has been shown in such young human brains. Small toxic amyloid clumps were found in neurons of deceased young adults. The clumps grew larger in the brains of normal older adults and those with Alzheimer's. The clumps likely damage and eventually kill memory-related neurons.
