Lhx2 creator gene for brain tissue repair

UCI study identifies the specific role for gene linked to cortical development, cerebral cortex points to potential stem cell treatments. – University of California, Irvine researchers have identified a gene that is specifically responsible for generating the cerebral cortex, a finding that could lead to stem cell therapies to treat brain injuries and diseases such as stroke and Alzheimer’s.

Fragile X syndrome affecting brain cells

Dr. Kimberly Huber investigated how Fragile X syndrome affects communication between cells in the hippocampus, a region of the brain that is involved in learning and memory. Fragile X syndrome is the most common cause of inherited mental retardation and the most common genetic cause of autism. – Researchers at UT Southwestern Medical Center are uncovering how brain cells are affected in Fragile X syndrome, the most common cause of inherited mental retardation and the most common genetic cause of autism.

Older surgical patients at greater risk for developing cognitive problems

Patients over the age of 60 who have elective surgeries such as joint replacements, hysterectomies and other non-emergency, inpatient procedures, are at an increased risk for long-term cognitive problems, according to a new study led by Duke University Medical Center researchers. – Duke University Medical Center researchers reveal that the patients over the age of 60 who have elective surgeries such as joint replacements, hysterectomies and other non-emergency, inpatient procedures, are at an increased risk for long-term cognitive problems.

Brain imaging and genetic studies link thinking patterns to addiction

Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more “impulsive” neural activity. – Alcoholics are more impulsive than non-addicted people making financial decisions, revealed by researcher Charlotte Boettiger at the University of North Carolina at Chapel Hill.

Potential drugs for mental retardation and autism treatment

US researchers say they have successfully corrected key symptoms of a type of autism and mental retardation in mice, a development which could offer sufferers a potential treatment. – Researchers at MIT’s Picower Institute for Learning and Memory have corrected key symptoms of mental retardation and autism in mice. The work, which will be reported in the Dec. 20 issue of Neuron, indicates that a certain class of drugs could have the same effect in humans. These drugs are not yet approved by the FDA, but will soon be entering into clinical trials.

White matter disease affects treatment in Alzheimer’s disease patients

There may be a difference in response to treatment in Alzheimer’s Disease (AD) patients with and without white matter disease in selective areas of the brain.
– Researchers at Sunnybrook have shown that there may be a difference in response to treatment in Alzheimer’s Disease (AD) patients with and without white matter disease in selective areas of the brain.

Aging brain failures to communicate

Cognitive decline in aging may be linked to disruption of communication between different regions of the brain.
– A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain. The new research, which used advanced medical imaging techniques to look at the brain function of 93 healthy individuals from 18 to 93 years old, shows that this decline happens even in the absence of serious pathologies like Alzheimer’s disease.
