Course of neurocognitive deficits in the prodrome and first episode of schizophrenia.
Understanding the trajectory of cognitive changes in the development of schizophrenia may shed light on the neurodevelopmental processes in the beginning stage of illness. Subjects at risk for psychosis (AR, n = 48), patients in their first episode of schizophrenia (FE, n = 20), and normal comparison subjects (n = 29) were assessed on a neurocognitive battery at baseline and at a 6-month follow...
متن کاملCorrigendum: “Ten year neurocognitive trajectories in first-episode psychosis”
OBJECTIVE Neurocognitive impairment is commonly reported at onset of psychotic disorders. However, the long-term neurocognitive course remains largely uninvestigated in first episode psychosis (FEP) and the relationship to clinically significant subgroups even more so. We report 10 year longitudinal neurocognitive development in a sample of FEP patients, and explore whether the trajectories of ...
متن کاملNeurocognitive dimensions characterising patients with first-episode psychosis.
BACKGROUND Assessment of neurocognitive dysfunction in schizophrenia is hampered by the multitude of tests used in the literature. AIMS We aimed to identify the main dimensions of an assessment battery for patients with first-episode psychosis and to estimate the relationship between dimension scores and gender, age, education, diagnosis and symptoms. METHOD Eight frequently used neuropsych...
متن کاملCerebral gray matter volume deficits in first episode psychosis.
BACKGROUND Structural brain differences including decreased gray matter and increased cerebrospinal fluid volumes have been observed in the brains of chronically ill patients with schizophrenia. We hypothesized that deficits in gray matter volume would be present in patients presenting with a first episode of nonaffective psychosis. METHODS We used magnetic resonance imaging to compare the br...
متن کاملMild Reinforcement Learning Deficits in Patients With First-Episode Psychosis.
Numerous studies have identified reinforcement learning (RL) deficits in schizophrenia. Most have focused on chronic patients with longstanding antipsychotic treatment, however, and studies of RL in early-illness patients have produced mixed results, particularly regarding gradual/procedural learning. No study has directly contrasted both rapid and gradual RL in first-episode psychosis (FEP) sa...
