Adolescent declines in cognitive performance predict later on psychosis By Liam Davenport, medwireNews Reporter Adolescents and adults experiencing relative declines in cognitive performance have an elevated risk for later psychosis, with a decline in verbal capability between 13 and 18 years a solid predictor, conclude experts. 'This shows that the premorbid cognitive deficit observed in schizophrenia and additional psychoses represents a disruption of neurodevelopment through the teenage years,' say James MacCabe, from King's University London, UK, and colleagues.'

The Pearson correlation coefficient between BMI and waist circumference was 0.74. Two thirds of individuals reported that that they had by no means smoked, 18 percent were former smokers, and 16 percent were current smokers. Association of Waistline and BMI Circumference with the Risk of Loss of life from Any Cause Among 33,916 women who had never smoked and who were followed from 1995 through 2008, there have been 770 deaths from all causes. We noticed a curvilinear association between BMI and the risk of loss of life from any trigger, with the lowest threat of loss of life for a BMI of 20.0 to 24.9 . Relative to a BMI of 22.5 to 24.9 , multivariable-adjusted hazard ratios for the higher categories increased from 1.12 for a BMI of 25.0 to 27.4 to 2.19 for a BMI of 40.0 to 49.9 .
