Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms

Smári, J., Rúrik Martinsson, D., & Einarsson, H. (2010). Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms. Scandinavian Journal of Psychology, 51, 392–397. The aim of the study was to investigate potential precursors of inflated responsibility (responsibility attitudes) and obsessive‐compulsive (OCD) symptoms. It was argued that both parental overprotection and impulsivity, separately and in interaction with each other, contribute to inflated responsibility and OCD symptoms. In a large sample of young adults (N = 570), self‐report measures of OCD symptoms (OCI‐R), responsibility attitudes (RAS), anxiety/depression (HADS), rearing practices (EMBU), present and past impulsivity/hyperactivity symptoms (IMP/HY) were administered. Overprotection as well as IMP/HY were found to predict OCD symptoms as well as inflated responsibility. Finally, a significant interaction was found between IMP/HY and overprotection with regard to both OCD symptoms and inflated responsibility. This effect reflected that IMP/HY was more strongly related to OCD symptoms and responsibility in people who had not been overprotected than in people who had been. Conversely overprotection was related to OCD symptoms and responsibility in people low but not in people high in IMP/HY. The results seem to indicate that the inadequacy between offer and need for parental control may play a role in the development of OCD symptoms.     

Parental reports of executive dysfunction in adolescents with bipolar disorder.

Bipolar disorder (BPD) is a serious mental illness that affects children and adolescents at a rate similar to that seen in adults. Extremely little is known, however, about cognitive functioning in childhood and adolescent BPD. The present study represents an initial effort to examine executive functioning in adolescents with BPD who are in a manic or mixed mood state, by collecting data from caregivers about the participants' performance on everyday tasks thought to be mediated by executive functioning abilities, using the Behavior Rating Inventory of Executive Function. In comparison to healthy volunteers, adolescents with BPD exhibited significant elevations across all of the measured functional domains. These elevations were evident even in adolescents with BPD who did not have comorbid ADHD, although they were most prominent in those with comorbidity. The findings suggest that adolescents with BPD have functional deficits on tasks requiring executive functioning skills that are not explicable solely on the basis of comorbid ADHD.     

Brain network dysfunction in bipolar disorder

Bipolar disorder is a common psychiatric condition with significant associated morbidity and mortality. Despite its significance, the neurophysiology and neuropathology of this illness is incompletely understood. Recent advances in neuroimaging techniques have helped to begin clarifying these areas. Specifically, bipolar disorder appears to arise from abnormalities within discrete brain networks (eg, the anterior limbic network). The expression of the symptoms of bipolar disorder does not appear to result from single, localized brain lesions, but rather are emergent properties of dysfunction of these brain networks. As neuroimaging techniques continue to improve, the underlying neural basis of bipolar disorder will be clarified.
