White matter alterations evident before psychosis development

Results from a UK study show that white matter integrity is reduced in patients at ultra-high risk for psychosis, although to a lesser extent than in first-episode psychosis patients.

MRI, EEG may predict children’s epilepsy risk after long febrile seizures

Children who have prolonged febrile seizures are at increased risk for magnetic resonance imaging observed hippocampal injury and abnormal hippocampal and temporal development, show results from the Consequences of Prolonged Febrile Seizures in Childhood study.

Patients with obsessive-compulsive disorder worry considerably more than general population

Patients with obsessive-compulsive disorder are characterised by persistent thoughts and repetitive behaviours. A new study reveals that sufferers worry considerably more than the general population in the face of morality problems.

Mayo Clinic receives FDA approval for Choline C 11 Injection to help detect prostate cancer

Mayo Clinic has received U.S. Food and Drug Administration approval to produce and administer Choline C 11 Injection, an imaging agent used during a positron emission tomography (PET) scan to help detect sites of recurrent prostate cancer. Mayo Clinic is the first, and currently only, institution in North America approved to produce this imaging agent.

Physical activity reduces dementia risk in elderly

Physical activity reduces the risk for cognitive impairment, particularly vascular dementia, in older people who have developed white matter changes, shows research.

Sensory substitution devices provide visual information to the blind via existing senses

Common wisdom has it that if the visual cortex in the brain is deprived of visual information in early infanthood, it may never develop properly its functional specialization, making sight restoration later in life almost impossible.

EUROECHO 2012 reveals how imaging improves early diagnosis of atherosclerosis

"Atherosclerosis is the leading cause of cardiovascular disease and the leading killer in Europe," said Professor Patrizio Lancellotti, President-Elect of the EACVI and Chairman of the EUROECHO Scientific Programme Committee. "Many of these deaths could be averted by diagnosis at a preclinical stage or early after the onset of symptoms."

Weight loss can help improve quality of sleep among obese people

Weight loss, whether it's from dietary changes alone or from diet combined with exercise, can help improve the quality of sleep among people who are overweight or obese, according to a new study by Johns Hopkins researchers.

Early treatment improves behavior, communication and brain function in children with autism

When given early treatment, children with autism spectrum disorders (ASD) made significant improvements in behavior, communication, and most strikingly, brain function, Yale School of Medicine researchers report in a new study.

Studies shake up Alzheimer’s hypotheses

Two studies in people at genetic risk for Alzheimer’s disease reveal very early changes in brain structure and function that may actually precede amyloid beta deposition.

Testosterone exposure early in life can have lasting impact on brain function and behavior

New findings led by Dr. Michael Lombardo, Prof. Simon Baron-Cohen and colleagues at the University of Cambridge indicate that testosterone levels early in fetal development influence later sensitivity of brain regions related to reward processing and affect an individual's susceptibility to engage in behavior, that in extremes, are related to several neuropsychiatric conditions that asymmetrically affect one sex more than the other.

Imaging-based therapy benefits ‘wake-up stroke’ patients

Undertaking thrombolysis on the basis of magnetic resonance imaging findings in patients with stroke of unknown onset time may double their chances for a good outcome, say researchers.

Study reveals why MRI brain images are so sensitive to the direction in which nerve fibres run

World-leading experts in Magnetic Resonance Imaging from The University of Nottingham's Sir Peter Mansfield Magnetic Resonance Centre have made a key discovery which could give the medical world a new tool for the improved diagnosis and monitoring of brain diseases like multiple sclerosis.

Study explores impact of IL1β on brain function alterations associated with schizophrenia

There are a growing number of clues that immune and inflammatory mechanisms are important for the biology of schizophrenia. In a new study in Biological Psychiatry, Dr. Mar Fatjó-Vilas and colleagues explored the impact of the interleukin-1β gene (IL1β) on brain function alterations associated with schizophrenia.
