Original Source: Cortical and frontal atrophy are associated with cognitive impairment in age-related confluent white-matter lesion.
Objective Although age-related confluent white-matter lesion (WML) is an important substrate for cognitive impairment, the mechanisms whereby WML induces cognitive impairment are uncertain. The authors investigated cognitive predictors in patients with confluent WML. Methods Among 100 patients with ischaemic stroke with confluent WML on MRI, the authors assessed executive function and global cognition by the Mattis Dementia Rating Scale-Initiation/Perseveration Subscale (MDRS I/P) and Mini-Mental State Exam...

Neuronal reference frames for social decisions in primate frontal cortex
The authors studied how neurons in three frontal cortical areas encode the outcomes of social decisions as monkeys performed a social reward allocation task. Orbitofrontal cortex (OFC) neurons signale...
Reasoning and behavioral control dependent on different regions of frontal lobes
The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes-which are located just behind and above the...
Men who are heavy drinkers and homeless for long periods of time have 400 times the number of head injuries as the general population, according to a new study by researchers who said they were shocke...
Neural mechanism underlying drug cravings
Addiction may result from abnormal brain circuitry in the frontal cortex, the part of the brain that controls decision-making. Researchers report that the lateral and orbital regions of the frontal co...
Brain frontal lobes not sole center of human intelligence, comparative research suggests
Human intelligence cannot be explained by the size of the brain's frontal lobes, say researchers. Research into the comparative size of the frontal lobes in humans and other species has determined tha...
Researchers turn concepts about head injuries in sports upside down
In the British Medical Journal, concepts about head injuries in sports are now being turned upside down by a group of researchers at Umeå University: Impaired brain function is rather a risk factor f...
Brain development delayed in ADHD, study shows
Is attention-deficit/hyperactivity disorder (ADHD) due to a delay in brain development or the result of complete deviation from typical development? Psychologists found that the development of the cor...

Cortical atrophy in ALS is critically associated with neuropsychiatric and cognitive changes.
OBJECTIVE: To characterize the patterns of brain atrophy in patients with amyotrophic lateral sclerosis (ALS) with and without cognitive and neuropsychiatric symptoms, in comparison to controls and pa...
Cortical and cerebellar atrophy, but no lesion in a patient with neuro-Behçet's disease
Neuro-Behçet's disease (NBD) is a rare clinical entity. There are no reports about cortical atrophy in NBD. We report a patient with NBD exhibiting only cortical and cerebellar atrophy without any le...
Background: Fatigue is one of the most frequent symptoms suffered by patients affected by multiple sclerosis. The patho-physiological basis of multiple sclerosis-related fatigue remains to be elucidat...
BACKGROUND:: Several studies have reported the relationship between craniomaxillofacial fractures, cervical spine injuries and head injuries with varying results. Life-threatening injuries to the head...
Head circumference, atrophy, and cognition: implications for brain reserve in Alzheimer disease.
BACKGROUND: Clinical and epidemiologic studies suggest that patients with Alzheimer disease (AD) with larger head circumference have better cognitive performance at the same level of brain pathology t...
