Background: Childhood abuse is associated with structural brain abnormalities. Few studies have investigated white matter tract abnormalities in medication-naive, drug-free individuals who experienced childhood abuse. We examined the association between childhood abuse and abnormalities in white matter tracts in that population, controlling for psychiatric comorbidities.

We examined the effect of childhood abuse and abuse-by-gene () interaction on functional brain connectivity during error processing in medication/drug-free adolescents. Functional connectivity was compared, using generalized psychophysiological interaction (gPPI) analysis of functional magnetic resonance imaging (fMRI) data, between 22 age- and gender-matched medication-naïve and substance abuse-free adolescents exposed to severe childhood abuse and 27 healthy controls, while they performed an individually adjusted tracking stop-signal task, designed to elicit 50% inhibition failures.

This pioneering functional magnetic resonance imaging (fMRI) study investigated the effects of severe childhood maltreatment on emotion processing while controlling for psychiatric conditions, medication and substance abuse.
Method: Twenty medication-naive, substance abuse-free adolescents with a history of childhood abuse, 20 psychiatric control adolescents matched on psychiatric diagnoses but with no maltreatment and 27 healthy controls underwent a fMRI emotion discrimination task comprising fearful, angry, sad happy and neutral dynamic facial expressions.
Childhood maltreatment is associated with attention deficits. We examined the effect of childhood abuse and abuse-by-gene (5-HTTLPR, MAOA, FKBP5) interaction on functional brain connectivity during sustained attention in medication/drug-free adolescents. Functional connectivity was compared, using generalised psychophysiological interaction (gPPI) analysis of functional magnetic resonance imaging (fMRI) data, between 21 age-and gender-matched adolescents exposed to severe childhood abuse and 27 healthy controls, while they performed a parametrically modulated vigilance task requiring target detection with a progressively increasing load of sustained attention.

However, the majority of functional magnetic resonance imaging (fMRI) studies in childhood maltreatment have examined emotion processing, while very few studies have tested the neurofunctional substrates of cognitive functions and none of attention. This study investigated the association between severe childhood abuse and fMRI brain activation during a parametric sustained attention task with a progressively increasing load of sustained attention in 21 medication-naïve, drug-free young people with a history of childhood abuse controlling for psychiatric comorbidities by including 19 psychiatric controls matched for psychiatric diagnoses, and 27 healthy controls.

The authors used a stop-signal task to investigate the association between severe childhood abuse and inhibitory and error processing brain activation in medication-naive, drug-free young people with and without severe childhood abuse, controlling for psychiatric comorbidities by including a psychiatric control group.
Method: Using functional MRI, the authors compared brain activation in 22 age- and gender-matched young people exposed to severe childhood abuse, 17 psychiatric comparison subjects matched for psychiatric diagnoses with the abused group, and 27 healthy comparison subjects during an individually adjusted tracking stop-signal task designed to elicit 50% inhibition failures.
Objectives: Valid screening tools are needed to identify Indian children and adolescents with mental health problems, both for clinical or research purposes. The present study validated the Strengths and Difficulties Questionnaire (SDQ) in Malayalam across different informants and sub-scales.
Methods: A sample of 150 children and adolescents seen in a psychiatric clinic for children in Kerala, India was compared to a community sample of 1984 children from six surrounding urban and rural districts.
Backround: Prescribing for substance-dependent youth requires expert knowledge of developmental and contextual issues and use of largely unlicensed medicines. This first national survey aimed to determine the nature of pharmacological treatments delivered in England including the extent of maintenance therapy, supervised consumption and specialties prescribing.
Method: Data were gathered regarding opiate substitutes & other medications prescribed for opiate, alcohol & benzodiazepine dependence, drug & alcohol relapse prevention and comorbidities.
