An article published in the journal Archives of Pediatrics & Adolescent Medicine describes the evidence that the lack of parenting in children causes brain volume shrinks.
Erin E. Edmiston, BA, from Yale University and colleagues from Vanderbilt University compiled information from 42 people with adolescents ages 12 to 17 years without a psychiatric diagnosis to examine the relationship between abuse experienced by children with disorders of gray matter volume in the brain.
These findings indicate that although adolescent psychiatric disorders did not show in full, no physical shortage of gray matter brain detected by MRI brain scans.
"An estimated 3.7 million children received abuse every year in the United States. Since many cases are not exposed by the professionals, this figure may possibly be smaller than the number sebenanrnya," Edmiston said seeprti MedicalNewsToday.com reported on Tuesday (6 / 12 / 2011).
MRI brain scans showed reduced volume of corticostriatal-limbic brain gray matter in children and adults who have experienced violence in childhood.
Research subjects were selected from the group of children identified at high risk of experiencing violence or abuse from birth. Additional participants were also recruited to penelitii can determine the severity of persecution.
Data were collected through self-report questionnaire and questions relating to the five subtypes of child abuse, among others: Physical Abuse, Physical Neglect, Emotional Violence, Neglect Emotional, and Sexual Harassment.
The findings suggest that brain material changes in girls located in areas associated with emotion regulation, whereas changes in the brain nateri men are in the area which controls the urge or impulse behavior.
Scores obtained from study participants or the Child Trauma Questionnaire Childhood Trauma Questionnaire (CTQ) showed a negative correlation with the volume of brain gray matter in the prefrontal cortex, striatum, amygdala, sensory association cortex and cerebellum. That is, the greater the childhood trauma experienced, the smaller volume of gray matter in the brain.
Among the five subtypes of child abuse, physical abuse, neglect, and emotional neglect was the most associated with decreased gray matter volume. But there is no significant relationship between emotional abuse or sexual harassment with a brain.
Although adolescents who have experienced abuse have not had the symptoms and behaviors that can meet the criteria for psychiatric diagnosis, early detection and intervention can help improve function and reduce the risk of mood disorders, addictions, and other psychiatric disorders.
