BACKGROUND Grey matter and other structural brain abnormalities are consistently reported in first-onset schizophrenia, but less is known about the extent of neuroanatomical changes in first-onset affective psychosis. AIMS To determine which brain abnormalities are specific to (a) schizophrenia and (b) affective psychosis. METHOD We obtained dual-echo (proton density/T2-weighted) magnetic r...
Context Women with hypopituitarism have lower pregnancy rates after ovulation induction. Associated pituitary hormone deficiencies might play a role in this poorer outcome. Objective We evaluated fertility treatment and pregnancy outcomes in five women with childhood-onset combined pituitary hormone deficiencies (CPHD). Patients and Methods Five women with CPHD were referred for fertility t...
Cognitive dysfunction is a core feature of schizophrenia and is also present in bipolar disorder (BD). Whereas decreased intelligence precedes the onset of psychosis in schizophrenia and remains relatively stable thereafter; high intelligence is a risk factor for bipolar illness but cognitive function decreases after onset of symptoms. While in schizophrenia, many studies have been conducted on...
This contribution combines results of experiments with kinetic modelling to probe the unusual behaviour carbonyl sulfide (COS), a sulfur species that frequently arises in fuel systems. The identified CO and SO2 as primary oxidation products, no formation CO2. low ignition temperature (<600 K) COS observed prior conflicts high activation barrier for reaction + O2 → CO2 SO 211.3 kJ mol−1 on tradi...
Early onset schizophrenia (onset before adulthood) is a rare, severe, and chronic form of schizophrenia. The clinical presentation of schizophrenia at this unusually early age of onset has been associated with premorbid developmental abnormalities, poor response to neuroleptic treatment, greater admission rates, and poor prognosis. This is a brief, condensed review of current treatment strategi...
Blood oxygen level dependent (BOLD) signals characteristically exhibit an overshoot (transient signal increase) at the beginning of fMRI task blocks. This onset transient has often been overlooked as an independent measure of neuronal activity, but it may represent unique functional processes. We examined onset transient responses in normal subjects and individuals with schizophrenia performing...
BACKGROUND An increased rate of premorbid impairment has been reported in both child- and adolescent-onset schizophrenic and affective psychoses. AIMS To examine the evidence for a specific association between premorbid impairment and child- and adolescent-onset schizophrenia, and whether specific continuities exist between premorbid impairments and psychotic symptom dimensions. METHOD Retr...
The distinction between schizophrenia and chronic delusional syndromes (including the French concept of "psychose hallucinatoire chronique" [PHC] or chronic psychotic hallucinations, paraphrenia, and late paraphrenia) is currently used in various European countries, although there are no international criteria for chronic and bizarre delusions. The French concept of PHC is characterized by late...
BACKGROUND Childhood-onset schizophrenia is schizophrenia with onset prior to the age of 13 years. Although it is rare, people who suffer from schizophrenia at an early age appear to have a clinically severe form of the illness with poor long-term prognosis. Antipsychotic medication is one way of managing this rare but serious mental illness. OBJECTIVES To examine the effects of antipsychotic...
