Look for Borderline in Adolescents
Don't dismiss the possibility of comorbid borderline personality disorder in adolescents with severe psychiatric problems, wrote Dr. Andrew M. Chanen of the University of Melbourne, and his colleagues.
Borderline personality disorder (BPD) is diagnosed often in adults, but data in adolescents are limited, they said.
To define the psychiatric symptoms and functional abilities of adolescents with BPD, the researchers interviewed 177 psychiatric outpatients aged 15–18 years. The teens were divided into three groups: 46 patients with BPD, 88 patients with a personality disorder other than BPD, and 43 patients with no personality disorder. Adolescents in the BPD group met at least three of the DSM-IV criteria for BPD (J. Clin. Psychiatry 2007;68:297–306).
The BPD patients had significantly more and greater impairment compared with teens in the other two groups. BPD patients averaged more psychiatric diagnoses than did patients in either of the other two groups, and they were significantly more likely to have mood disorders, substance abuse/dependence, disruptive behavior disorders, and anxiety disorders than were the patients without personality disorders. In addition, teens with BPD were significantly more likely than were those in the other groups to have internalizing and externalizing problems (based on self-reports).
Breast-Feeding and PTSD
Among children who were hospitalized for severe burns or other injuries, those who were breast-fed during infancy experienced significantly fewer symptoms of posttraumatic stress disorder when queried 3 months after the injury, according to results of a poster presentation at the annual meeting of the International Society for Traumatic Stress Studies.
The study involved 29 children hospitalized at Shriners Burns Hospital, Boston, and 73 children hospitalized at Boston Medical Center for other injuries including motor vehicle accidents, gunshot wounds, and assaults. The children's ages averaged 13 years, and almost half of them had been breast-fed.
The investigators, including Katherine K. Bedard and Dr. Glenn N. Saxe of the department of child and adolescent psychiatry at Boston University and their colleagues, assessed the children's degree of posttraumatic stress disorder (PTSD) by administering the Child PTSD Reaction Index (CPTSD-RI), and they asked the child's parents whether the child had been breast-fed.
The average CPTSD-RI score was 18 among those who had been breast-fed (corresponding to “mild” PTSD according to standard interpretations of this measure) and 25 among children who had not been breast-fed (corresponding to “moderate” PTSD).
The history of breast-feeding was not associated with the child's age, injury severity, socioeconomic status, symptoms of PTSD among the parents, or family strain.
The meeting was also sponsored by Boston University.
Poor Reading Linked to Psychopathy
Adolescents with poor reading skills are significantly more likely to exhibit psychiatric disorders than are adolescents who have adequate reading skills, reported David B. Goldston, Ph.D., of Duke University, Durham, N.C., and his associates.
Although the link between attention-deficit hyperactivity disorder and reading problems is well known, few studies have addressed whether non-ADHD psychiatric comorbidities in young people with reading problems are related to the ADHD or to the reading problems (J. Am. Acad. Child Adolesc. Psychiatry 2007;46:25–32).
To determine associations between poor reading ability and psychiatric disorders in adolescence, Dr. Goldston and his colleagues reviewed psychiatric evaluations from 94 teens with poor reading skills and 94 teens with typical reading skills who were part of a larger longitudinal study.
After adjustment for sociodemographic variables, adolescents with reading problems were significantly more likely to have ADHD and significantly more likely to have anxiety disorders than were those with typical reading skills.
Overall, 14.4% of poor readers met criteria for affective disorders, compared with 7.9% of typical readers. Major depressive disorder (the most common affective disorder) was present in 12.9% of poor readers and 7.9% of typical readers.
In addition, 23.9% of poor readers met criteria for anxiety disorders, compared with 7.6% of typical readers. Social phobia (the most common anxiety disorder) was present in 15.2% of poor readers and 3.0% of typical readers.
Finally, 24.8% of the poor readers met criteria for disruptive behavior disorders, compared with 10.9% of the typical readers. ADHD (the most common disruptive behavior) was present in 18.0% of poor readers and 4.9% of typical readers, Dr. Goldston and his associates reported.
But after controlling for ADHD, they found that poor readers were still more than three times as likely as were typical readers to have anxiety disorders. In particular, poor readers were more than five times as likely to have generalized anxiety disorder and social phobia, compared with typical readers.
Poor reading ability also was significantly associated with higher overall levels of functional impairment, as well as impairment in the specific areas of role functioning, behavior toward others, thinking, and mood.
