Ectodermal disturbance in development shared by anorexia and schizophrenia may reflect neurodevelopmental abnormalities.

Minor physical abnormalities (MPA) are subtle dysmorphic features of bodily structures that have little or no impact on function. Most MPA develop during the first gestational trimester and are considered as important indicators of neuroectodermal deficiencies emerging during early brain development. A higher frequency of MPA was confirmed in schizophrenia patients and their relatives, when compared to controls.

Inpatient psychiatric treatment is not always effective in adolescent sample.

Objective: Numerous studies confirm efficacy of psychiatric treatment as well as psychiatric placebo. The aim of the current study was the assessment of improvement rate and factors associated with treatment response in naturalistic group of adolescent inpatients.

Methods: Eighty two consecutive adolescent inpatients were recruited.

Which aspects of long-term outcome are predicted by positive and negative symptoms in early-onset psychosis? An exploratory eight-year follow-up study.

Background: Early-onset psychoses show substantial variability of diagnostic and functional outcome. Finding reliable prognostic factors may allow to allocate resources to those with the worst prognosis. The aim of the study was to gain new insights regarding the potential value of baseline negative and positive symptoms as predictors of outcome in psychoses of early onset.

Executive impairment predicts schizophrenia diagnosis and treatment status in mid-term follow-up of early-onset psychosis.

Objectives: Early-onset psychoses (EOP) vary considerably with regard to diagnostic stability and functional outcome. The aim of this study was the assessment of executive dysfunction as a predictor of outcome in EOP.

Method: This was a retrospective cohort study.

Adolescent insanity revisited: course and outcome in early-onset schizophrenia spectrum psychoses in an 8-year follow-up study.

Objectives: Despite inclusion of adolescent insanity-a concept proposed by Thomas Clouston in late XIX century-into the broader nosological entity of dementia praecox, the uniqueness of early psychosis is still discussed. The aim of the current study is the assessment of course and outcome in the large sample of early-onset psychosis subjects.

Method: Of 299 patients hospitalized in the period 1998-2008 in an adolescent psychiatry ward with schizophrenia spectrum diagnosis 158 completed a follow-up interview.

[Altered visual information processing in anorectic girls--the study on potentials related to the test of attention].

Aim: Combined biological and psychological basis of anorexia nervosa, related to increased self-control, low self-esteem and peculiar motivation, makes a synthetic approach still hard to achieve. The presented study assessed cognitive functions in anorectic patients with respect to both neuropsychological (test of attention) and biological (electrophysiology of information processing) approaches, and their reciprocal interrelations as well.

Methods: Eleven adolescent anorectic females and 10 control subjects performed the Continuous Attention Test CAT.
