Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. The research was carried […]

Abnormal Brain Structure Linked To Chronic Cocaine Abuse
Researchers at the University of Cambridge have identified abnormal brain structures in the frontal lobe of cocaine users’ brains which are linked to their compulsive cocaine-using behavior. The research was led by Dr. Ersche of the Behavioural and Clinical Neuroscience Institute (BCNI) at the University of Cambridge. Their findings were published today, 21 June, in […]
Brain Scan Identifies Patterns Of Plaques And Tangles In Adults With Down Syndrome
In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer’s disease — in adults with Down syndrome. Published in the June edition of the Archives of Neurology, the finding may offer an additional clinical tool […]
Autism Changes The Molecular Structure Of The Brain
For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain. Now a UCLA study is the first to reveal how the disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure […]
EEG Researchers Investigate Cortical Response To And Memory Of Touch
Neuroscientists of the Charité – Universitätsmedizin Berlin have now been able for the first time to document deliberate control of touch sensations in human working memory. It has been shown that the human brain can remember several touch sensations at the same time and consciously retrieve the touch if concentration is focused on these touches. […]
Patients With Alzheimer’s Disease Have Disruption Of Brain Circadian Rhythms
Twenty-four hour cycles, known as circadian rhythms, are important for proper body functions, including for normal brain function and mental health. Disruptions of circadian rhythms and sleep-wake cycles have been observed in patients with Alzheimer’s disease. A new study by Douglas Institute researchers unravels a possible basis for these perturbations.
Integrity Of Brain Reward System Linked To Relapse After Subtance Abuse Treatment
At least 60 percent of individuals treated for an alcohol use disorder will relapse, typically within six months of treatment Given that the brain reward system (BRS) is implicated in the development and maintenance of all forms of addictive disorders, this study compared thickness, surface area, and volume of neocortical components of the BRS among […]
Genetic Makeup And Duration Of Substance Abuse Reduce Brain Neurons In Drug Addiction
A study conducted at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory demonstrated that drug addicted individuals who have a certain genetic makeup have decreased gray matter density – and therefore fewer neurons – in areas of the brain that are essential for decision-making, self-control, and learning and memory. The research, conducted by scientists […]
