Novel neuroimaging technique reveals evidence of cocaine-induced cerebral microischemia

Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels - including small capillaries - of the brain.

Alzheimer's disease diagnosis within minutes using a simple brain scan

Groundbreaking research taking place at the University of York could lead to Alzheimer's disease being diagnosed in minutes using a simple brain scan.

Study provides direct evidence for persistent activity in medial entorhinal cortex layer neurons

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Prefrontal-limbic network dysfunction in depressive BD

Study findings suggest that patients in the depressive phase of bipolar disorder show dysfunction in prefrontal-limbic networks and associated striatal systems, which can be measured using amplitude of low-frequency fluctuations.

Alzheimer's can involve mixture of proteins from different neurodegenerative diseases

Neurodegenerative diseases such as Alzheimer's or Parkinson's are characterised by the loss of nerve cells and the deposition of proteins in the brain tissue. A group of researchers led by Gabor G. Kovacs from the Clinical Institute of Neurology at the MedUni Vienna has now demonstrated that Alzheimer's disease does not just - as previously believed - involve the proteins that are attributed to Alzheimer's, but instead the condition can involve a mixture of interacting proteins from different neurodegenerative diseases.

Navidea commences enrollment in [18F]NAV4694 Phase 2 study for Alzheimer's

Navidea Biopharmaceuticals, Inc., a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that enrollment has commenced at two sites participating in its Phase 2, open-label, safety and efficacy PET imaging study of [18F]NAV4694 for detection of cerebral β-amyloid plaque in subjects diagnosed with probable Alzheimer's disease (AD).

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.

Moderate exercise may help people cope with future anxiety and stress

Moderate exercise may help people cope with anxiety and stress for an extended period of time post-workout, according to a study by kinesiology researchers in the University of Maryland School of Public Health published in the journal Medicine and Science in Sports and Exercise.

GE Healthcare announces data from [18F]flutemetamol phase III studies on Alzheimer's

GE Healthcare today announced pooled results from phase III brain autopsy and biopsy studies on the investigational PET amyloid imaging agent, [18F]flutemetamol, which showed a strong concordance between [18F]flutemetamol images and Alzheimer's disease-associated beta amyloid brain pathology.

CHOP’s Center for Autism Research receives ACE grant to identify early signs of ASD

The Center for Autism Research at The Children's Hospital of Philadelphia (CHOP) announced today that it will continue its research to identify early signs of autism spectrum disorders (ASD) through a grant from the National Institutes of Health (NIH) Autism Centers of Excellence (ACE) research program.

Neuroscientists try to decipher precisely how human brain constructs our sense of self

Ancient Greek philosophers considered the ability to "know thyself" as the pinnacle of humanity. Now, thousands of years later, neuroscientists are trying to decipher precisely how the human brain constructs our sense of self.

Short-term intervention alters neural architecture of stutterers

A short-term intervention in patients who stutter can help reorganize the intrinsic functional architecture of speech–language processes, a Chinese study shows.

Effects on white matter brain volume from long-term alcoholism are different for men and women

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men.

Scientists take step toward developing blood test for Alzheimer's

The possibility of an inexpensive, convenient test for Alzheimer's disease has been on the horizon for several years, but previous research leads have been hard to duplicate.

Scientists discover biological marker that may help identify patients’ response to antidepressants

Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent's underlying mechanism, which are vital for drug development, say National Institutes of Health researchers.

AD hits hardest among people in their 60s and 70s

The greatest risk factor for Alzheimer's disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent. But researchers at the University of California, San Diego School of Medicine say AD hits hardest among the "younger elderly" - people in their 60s and 70s - who show faster rates of brain tissue loss and cognitive decline than AD patients 80 years and older.

Evidence for ADHD due to delay in brain development

Is attention-deficit/hyperactivity disorder (ADHD) due to a delay in brain development or the result of complete deviation from typical development? In the current issue of Biological Psychiatry, Dr. Philip Shaw and colleagues present evidence for delay based on a study by the National Institutes of Health.

Researchers use neuroimaging to study brains of preschool children with ADHD symptoms

Young children often have problems paying attention or concentrating, but when are these problems serious enough for parents and teachers to be concerned? According to estimates from the Centers for Disease Control, 1 in 11 school-aged children are diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD), but research suggests that the warning signs often appear even before the demands of school begin.
