BACKGROUND An extensive range of molecular defects have been identified in the human mitochondrial genome (mitochondrial DNA); many are associated with well-characterized, progressive neurological syndromes, but a minority of patients have uncharacteristic phenotypes in which symptoms may be relatively mild. OBJECTIVE To describe a novel transfer RNA(Phe)(More)
OBJECTIVE The aim was to investigate the association of pretreatment social functioning (12 months before initial presentation) with symptom dimensions and social functioning at 1-year follow-up. METHOD Fifty-six adolescents, age 14-18, first admitted for early onset psychosis, were evaluated at baseline and 1-year follow-up assessing psychopathology(More)
We report a 22-year-old female who presented with distal muscular atrophy and weakness in all limbs for two years. Reflexes were symmetrically brisk and electrodiagnostic studies were consistent with upper and lower motor neuron involvement. A diagnosis of juvenile ALS was considered. However, surgery for achalasia in childhood and identification of(More)
Post mortem studies have shown volume changes of the hypothalamus in psychiatric patients. With 7T magnetic resonance imaging this effect can now be investigated in vivo in detail. To benefit from the sub-millimeter resolution requires an improved segmentation procedure. The traditional anatomical landmarks of the hypothalamus were refined using 7T(More)
The authors describe a 47-year-old man who presented with proximal muscle weakness, myalgia, elevated creatine kinase, and features of a pure myopathic syndrome in whom they have identified a novel mutation in the mitochondrial tRNA(Ala) gene. This 5591G>A transition is heteroplasmic, segregates with cytochrome c oxidase deficiency in single muscle fibers,(More)
A large body of evidence indicates that the hypothalamus is involved in pathogenetic mechanisms of mood disorders. It has been suggested that functional abnormalities of the hypothalamus are associated with structural hypothalamic changes. Structural neuroimaging allows in vivo investigation of the hypothalamus that may shed light on the underlying(More)
BACKGROUND Impairment of sleep-wake cycles and circadian rhythm are found in human narcolepsy which is characterized by deficiency of hypocretin (hcrt) or its receptors. A disturbed electroencephalography (EEG) based vigilance regulation is also found in affective disorders such as major depressive disorder (MDD) and mania. For the first time, in the(More)
It is only possible to diagnose an adjustment disorder if there is an explicit connection to a stressful life event. Clinically this disorder is marked by a wide variability of symptoms (e.g. depressive mood, anxiety). The prodromal symptoms have not been unequivocally differentiated from those of other mental disorders and normal adaptation processes.(More)
A high purity factor VIII/von Willebrand Factor (FVIII/vWF) concentrate (IMMUNATE [STIM plus]) (n = 6 batches), and a high purity factor IX (FIX) concentrate (IMMUNINE [STIM plus]) (n = 7 batches), were assessed in vitro for their applicability to continuous infusion. Parameters pertinent to continuous infusion were investigated and included stability,(More)
Depressive patients exhibit symptoms of impaired regulation of wakefulness with hyperarousal and agitation as well as difficulties to falling asleep and preserving sleep continuity. Changes in hypocretin (hcrt) levels as polypeptides with impact on arousal and sleep-wake-regulation have been discussed in affective disorders but have not been investigated in(More)
