Smoking, Schizophrenia Linked by Altered Nicotine Signals

September 16, 2014 1:25 pm | News | Comments

A new study shows how schizophrenia is associated with increased rates and intensity of tobacco smoking by showing that the level of nicotine receptors in the brain was lower in schizophrenia patients than in a matched healthy group.     

Key Role of Language Gene Identified

September 16, 2014 1:18 pm | News | Comments

Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.

Jacobsen Syndrome, Autism Linked

September 15, 2014 1:28 pm | News | Comments

A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.

Neural Compensation Found in People With Alzheimer’s-related Protein

September 15, 2014 12:48 pm | News | Comments

The human brain is capable of a neural workaround that compensates for the buildup of beta-amyloid, a destructive protein associated with Alzheimer’s disease, according to a new study.                   

Schizophrenia is Actually 8 Genetic Disorders

September 15, 2014 12:41 pm | News | Comments

New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms.                             

Neurochemical Imbalance Discovered in Schizophrenia

September 11, 2014 3:28 pm | News | Comments

Using human induced pluripotent stem cells (hiPSCs), researchers have discovered that neurons from patients with schizophrenia secrete higher amounts of three neurotransmitters broadly implicated in a range of psychiatric disorders.     

New Evidence Shows Sleep Apnea Hurts Your Brain

September 11, 2014 12:08 pm | News | Comments

Employing a measure rarely used in sleep apnea studies, researchers uncovered evidence of what may be damaging the brain in people with the sleep disorder— weaker brain blood flow.

Eating Habits, Body Fat Related to Brain Differences

September 10, 2014 12:00 pm | News | Comments

People who are obese may be more susceptible to environmental food cues than their lean counterparts due to differences in brain chemistry that make eating more habitual and less rewarding, according to a new study.
