The neuroendocrine response to L-5-hydroxytryptophan was compared in 37 prepubertal children who met the Research Diagnostic Criteria for major depressive disorder with that in 23 normal children with no lifetime history of any psychiatric disorder and very low rates of depression in both first- and second-degree relatives. Intravenous L-5-hydroxytryptophan(More)
Plasma cortisol levels were determined every 20 min for 24 hr in depressed adolescents (n = 27) meeting research diagnostic criteria (RDC) for major depressive disorder (MDD) and normal controls (n = 32). All subjects were between 12 and 18 years of age, at least Tanner Stage III of sexual development, medically healthy, and medication free at the time of(More)
The SORL1 protein plays a protective role against the secretion of the amyloid β peptide, a key event in the pathogeny of Alzheimer's disease. We assessed the impact of SORL1 rare variants in early-onset Alzheimer's disease (EOAD) in a case-control setting. We conducted a whole exome analysis among 484 French EOAD patients and 498 ethnically matched(More)
The lifetime and current prevalence of depression and anxiety disorders was determined in 41 children with Crohn's disease, 12 children with ulcerative colitis, and 52 children with cystic fibrosis, using the Kiddie-Schedule for Affective Disorders and Schizophrenia interview. The lifetime prevalence of depression was 29% in Crohn's disease, 21% in(More)
The Leyton Obsessional Inventory-Child Version was administered to 33 children with Crohn's disease, 11 with ulcerative colitis, and 46 with cystic fibrosis. Subjects with ulcerative colitis scored significantly higher on total number of obsessional symptoms and degree of resistance to symptoms than subjects with Crohn's disease. Scores of subjects with(More)
To assess the role of rare copy number variations in Alzheimer's disease (AD), we conducted a case-control study using whole-exome sequencing data from 522 early-onset cases and 584 controls. The most recurrent rearrangement was a 17q21.31 microduplication, overlapping the CRHR1, MAPT, STH and KANSL1 genes that was found in four cases, including one de novo(More)
Because of its neuroendocrine effects, amphetamine infusion has been used as a probe to investigate neurobiological correlates of depressive illness. In two separate studies, a total of 72 adolescents with major depressive disorder and 66 normal adolescents were given dextroamphetamine, 0.15 mg/kg, intravenously. Their cortisol, growth hormone, and(More)
