 Whether people with Alzheimer's disease benefit in the long term from non-drug treatment interventions remains an unanswered question. This unsatisfactory finding is mainly due to the fact that convincing studies are lacking so far. For individual approaches, the studies provide indications of a benefit, but also of harm. |

 Patients with schizophrenia are able to correctly see through an illusion known as the ‘hollow mask’ illusion, probably because their brain disconnects ‘what the eyes see’ from what ‘the brain thinks it is seeing’, according to a joint UK and German study published in the journal NeuroImage. The findings shed light on why cannabis users may also be less deceived by the illusion whilst on the drug. |

Researchers at Children's Hospital Boston have developed a slow-release anesthetic drug-delivery system that could potentially revolutionize treatment of pain during and after surgery, and may also have a large impact on chronic pain management. |

 Through a study carried out at the Universities of La Laguna and Valencia, it has been verified that the brain distinguishes between vowels and consonants differently. Neuronal mechanisms change when they are processed and, when it comes to lexical access; both have a different status in our mind, thus contributing differently to this basic process of visual word recognition. |

 Dogs and small children who share similar social environments appear to understand human gestures in comparable ways, according to Gabriella Lakatos from Eötvös University in Budapest, Hungary, and her team. Looking at how dogs and young children respond to adult pointing actions, Lakatos shows that 3-year-olds rely on the direction of the index finger to locate a hidden object, whereas 2-year-olds and dogs respond instead to the protruding body part, even if the index finger is pointing in the opposite direction. |

 A recent study by Mount Sinai faculty suggests that a gene associated with onset of type-2 diabetes also decreases in Alzheimer's disease dementia cases. The research, led by Dr. Giulio Maria Pasinetti, MD, Ph.D., The Aidekman Family Professor in Neurology, and Professor of Psychiatry and Geriatrics and Adult Development at Mount Sinai School of Medicine, was published the week of April 6 in the scientific journal, Archives of Neurology. |

Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise, according to a new brain imaging study by scientists from the University of Oxford and Imperial College London. The results may support the idea that the brain's memory function may gradually wear itself out in those who go on to develop Alzheimer's. |

 Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. |

Drug addiction affects millions of people around the world, causing numerous problems ranging from emotional and psychological difficulties to physical and health issues. Initial drug use can be motivated by curiosity or peer pressure, but in some animals, such as rats, it can also be the result of a stressful early life event, such as social isolation. A new study examines the impact of social isolation on the animal’s response to cocaine. |

 It is not easy to find your student bedroom when you left university 10, 20 or 30 years ago. But once you have found it, you can easily return the next day. Indeed, by reactivating this memory, it has been strengthened and updated to provide spatial references. |

Alzheimer’s disease has reached epidemic proportions in western society. Researchers at the German Center for Neurodegenerative Diseases (DZNE) at Ludwig-Maximilians-Universitaet (LMU) Meunchen have now developed the first animal model that directly traces the demise of neurons in the brain, and thereby allows better testing of the action of potential drugs. |

 Sleep is such an essential part of human existence that we spend about a third of our lives doing it -- some more successfully than others. Sleep disorders afflict some 50-70 million people in the United States and are a major cause of disease and injury. |

 After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses cycle with sleep or are simply inactive has remained a mystery, until now. |

 If you've ever been sleep-deprived, you know the feeling that your brain is full of wool. Now, a study published in the April 3 edition of the journal Science has molecular and structural evidence of that woolly feeling — proteins that build up in the brains of sleep-deprived fruit flies and drop to lower levels in the brains of the well-rested. The proteins are located in the synapses, those specialized parts of neurons that allow brain cells to communicate with other neurons. |

 Instruments that are intended to measure change over time need to emphasize sensitivity to change as a central property. The aims of this report are to test whether the MOODS-SR, a measure of mood spectrum symptomatology, is sensitive to changes during acute and continuation treatment of depression and whether residual mood spectrum symptoms predict relapse in the subsequent 6 months. |

 Mapping the billions of connections in the brain is a grand challenge in neuroscience. The current method for mapping interconnected brain cells involves the use of room-size microscopes known as transmission electron microscopes (TEMs). Until now the process of mapping even small areas of the brain using these massive machines would have required several decades. |
