Gene variant doubles risk for obsessive-compulsive disorder

Scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) have identified a previously unknown gene variant that doubles an individual's risk for obsessive-compulsive disorder (OCD).

Mood-swings impair attention and memory

A review on the neuropsychological aspects of bipolar disorder (alternations of mania and depression) by the group of Eduard Vieta (University of Barcelona) points to impairments in intellectual functioning in this patient population.

Major biomarker candidates for Alzheimer's disease explored

Alzheimer's disease - specific biomarkers clearly are needed for the differential diagnosis of cognitive impairment in the elderly.

Dyslexic children exhibit a different pattern of brain activity while reading

Brain images of children with dyslexia taken before they received spelling instruction show that they have different patterns of neural activity than do good spellers when doing language tasks related to spelling. But after specialized treatment emphasizing the letters in words, they showed similar patterns of brain activity.

First potential treatment for intracerebral hemorrhage

The first potential treatment for strokes that result from bleeding in the brain is under study at the Medical College of Georgia.

New techniques are able to detect and monitor Alzheimer's disease

The search for new measures, or "biomarkers," to detect Alzheimer's disease (AD) before signs of memory loss appear has advanced an important step in a study by researchers at Washington University in St. Louis, MO, and the University of Pittsburgh.

Chronic pain sufferers may be able to reduce pain levels by studying their own live brain images

Chronic pain sufferers may be able to reduce pain levels by studying their own live brain images, researchers at the Stanford University School of Medicine report in a new study.

Meditation may slow down brain aging

The regular practice of meditation appears to produce structural changes in areas of the brain associated with attention and sensory processing.

MRI helps early diagnosis of schizophrenia

Researchers may have discovered a new way that may ultimately assist in the early diagnosis of schizophrenia - by utilizing MRI to study the patient's brain.

Research has important implications for autism

New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties.

Combining fMRI and PET scanning creates a way to compare different measurements of the brain's function concurrently

Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain's function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzheimer's disease.

New way to measure the impact of AIDS on the living brain

A new University of California - Los Angeles/University of Pittsburgh imaging study for the first time shows the selective pattern of destruction inflicted by AIDS on brain regions that control motor, language and sensory functions. High-resolution 3-D color scans created from magnetic resonance images (MRI) vividly illustrate the damage.

Important developmental link between the cerebrum and the cerebellum

Higher cognitive functions, like language and visual processing, have long been thought to reside primarily in the brain's cerebrum. But a body of research in premature infants at Children's Hospital Boston is documenting an important role for the cerebellum

Been there, done that!

One of the neural oddities of "declarative" memory--the recall of past things and events--is that some experiments have shown that recognizing a familiar object is accompanied by a reduction in activity of the brain's memory centers in the medial temporal lobe. Such a reduction seems counterintuitive, since remembering seems to be a positive event.

Riluzole appears to have significant antiobsessional, antidepressant, and antianxiety properties

A medication used to ease symptoms of amyotrophic lateral sclerosis, or Lou Gehrig's disease, also is helpful in treating people with treatment-resistant obsessive-compulsive disorder (OCD), according to a pilot study at Yale School of Medicine.

Sleep helps memory

A good night's sleep triggers changes in the brain that help to improve memory, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).

Danger of mixing mobile phones and motoring

The reason talking on a cell phone makes drivers less safe may be that the brain can't simultaneously give full attention to both the visual task of driving and the auditory task of listening, a study by a Johns Hopkins University psychologist suggests.

Brain surgery for epilepsy means patients still free of fits 30 years later

A study has shown that thirty years after undergoing temporal lobectomy for epilepsy, half of patients are still free from seizures.

Evidence of cross-activation in brain regions of people who see letters and numbers in colors

Synesthesia, a condition characterized by one sensory experience generating another – so that shapes have tastes, for instance – is estimated to affect between 1 in 200 to 1 in 2,000 people. The most common form involves seeing specific letters or numbers (graphemes) in specific colors.

Extremely shy children have distinct facial expressions

Children who appear to have higher levels of shyness, or a particular gene, appear to have a different pattern of processing the signals of interpersonal hostility, according to a study in the January issue of The Archives of General Psychiatry.
