ADHD :: ADHD appears to be associated with depressed dopamine activity in brain

Adults with attention-deficit/hyperactivity disorder (ADHD) show a blunted response to the drug methylphenidate (Ritalin), which increases brain dopamine levels, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals. This suggests that dopamine dysfunction may be involved with ADHD symptoms and may contribute to substance abuse that often occurs simultaneously.

ADHD :: Gene variant is associated with brain anatomy, clinical course of ADHD

A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder (ADHD) and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Coffee & caffeine may protect memory in older women

Drinking more than three cups of coffee (or the equivalent in tea) per day or caffeine may help older women protect their thinking skills, according to a study published in the August 7, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Dementia :: In women, caffeine may protect memory, thinking skills

Caffeine may help older women protect their thinking skills, according to a study published in the August 7, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Glaucoma :: Alzheimer’s disease treatments may help treat major eye disease glaucoma

UK scientists have shown for the first time that key proteins involved in Alzheimer’s disease are also implicated in glaucoma, the major cause of irreversible blindness worldwide. Research carried out at the UCL Institute of Ophthalmology and funded by the Wellcome Trust has also shown that novel drugs being trialled for Alzheimer’s disease which target this protein may be used to treat glaucoma.

Brain :: Human knowledge is based upon directed connectivity between brain areas

Which brain processes enable humans to rapidly access their personal knowledge? What happens if humans perceive either familiar or unfamiliar objects? The answer to these questions may lie in the direction of information flow transmitted between specialized brain areas that together establish a dynamic cortical network. This finding is reported in the latest issue of the scientific journal PLoS ONE published on Aug. 1, 2007.

MRI :: Sports concussion research using fMRI provides insight for safe return-to-play decisions

Concussions are common in young athletes but the underlying changes in brain function that occur have been poorly understood. Now, a University of Pittsburgh School of Medicine study is the first to link changes in brain function directly to the recovery of the athlete. Results of the five-year study, funded by the National Institutes of Health, are published in the August issue of the scientific peer-reviewed journal, Neurosurgery, the official journal of the Congress of Neurological Surgeons.

Neurology :: Maturity Brings Richer Memories

MIT neuroscientists exploring how memory formation differs between children and adults have found that although the two groups have much in common, maturity brings richer memories.

Aging :: Exercise and mental stimulation boost memory late in life

Physical exercise is known to be good for the aging brain, but what about mental stimulation” Does enrichment that helps older people work well for the young and middle aged, or do they need something else” A report in the August issue of Behavioral Neuroscience tells how, in an animal experiment, older adults appear to benefit from either or both mental and physical enrichment. For the young and middle-aged, exercise is key.
