I can certainly see from this though how its so easy for the quacks to convince the parents its the cannabis thats done the damage visa vi mental health, its got to be better than blaming themselves esp if they're not being offered any hope for the future either just chemicals from the nhs to make matters worse.
CSF CRF offers clue to childhood trauma and adult mental illness link
Am J Psychiatry 2005; 162: 995–997
Researchers have found evidence to support the hypothesis that the severity of early life stress is associated with stress hormone abnormalities in adulthood that could lead to mental illness.
Royce Lee (The University of Chicago, Illinois, USA) and colleagues report in the American Journal of Psychiatry that a direct relationship between childhood trauma and cerebral spinal fluid corticotropic-releasing factor (CSF CRF) levels was detected in 20 men who met the DSM-IV criteria for personality disorders.
For their preliminary study, the researchers used lumbar puncture to obtain measurements of CSF CRF levels in 20 men with personality disorders. Childhood adversity experienced by the participants was also assessed, using the Childhood Trauma Questionnaire.
Analysis of the findings showed that CSF CRF concentrations were positively associated with the total score on the Childhood Trauma Questionnaire.
Specifically, men with scores above the median total score for childhood trauma had average CSF CRF levels of 60.5 pg/ml, compared with 28.5 pg/ml for those whose childhood trauma scores were below the median.
The researchers note that increases in CSF CRF levels were particularly evident among men reporting high levels of emotional neglect. The relationship between CSF CRF levels and physical and emotional abuse and CSF CRF levels and physical neglect were smaller in magnitude and not significant.
Age, race, socioeconomic status, and Global Assessment of Functioning scores were not associated with CSF CRF levels or with Childhood Trauma Questionnaire total score.
"Given the presence of CRF receptors in areas of the brain associated with emotional and cognitive processing such as the amygdala and neocortex, CRF may play a role in personality psychopathology," the researchers suggest.
"Further work in this area should clarify the links between childhood trauma, central nervous system neurochemistry, and personality psychopathology," they conclude.
Personally I believe they should add enviromental toxins to the list of probable causes too not just neglect and abuse seeing that most articles claiming to have found higher levels of psychosis have done so in the inner cities but hell you don't get research published if you dare blame lead from deisel fumes or heavy industrial pollution for the problems with kids brains.
