Psychomotor slowing in schizophrenia.
Psychomotor slowing (PS) is a cluster of symptoms that was already recognized in schizophrenia by its earliest investigators. Nevertheless, few studies have been dedicated to the clarification of the nature and the role of the phenomenon in this illness. Moreover, slowed psychomotor functioning is often not clearly delineated from reduced processing speed. The current, first review of all exist...
متن کاملPsychomotor slowing and planning deficits in schizophrenia.
The relative contribution of cognitive and motor processing to psychomotor slowing in schizophrenia was investigated using three tasks: a simple line-copying task and a more complex figure-copying task, both following a reaction paradigm, and a standard psychomotor test, the Digit Symbol Test (DST). Various movement variables of the task performances were derived from recordings made with the a...
متن کاملHow Cognitive is Psychomotor Slowing in Depression ?
The current meta-analysis explores the hypothesis that many of the apparently specific deficits that depressed subjects show on speeded cognitive tasks are actually the result of general (i.e., task-independent) slowing. Results of three analyses provided strong support for this hypothesis. The reaction times (RTs) of the depressed groups were consistently slower than those of the control group...
متن کاملPsychomotor slowing and subcortical-type dysfunction in depression.
Elderly patients with major depression and normal controls completed the Sternberg short-term memory scanning procedure and WAIS Digit Symbol. Depressed patients demonstrated psychomotor slowing on both tasks, but normal response latency as a function of memory set size on the Sternberg procedure. While cognitive-behavioural slowing may be observed in both depressive illness and subcortical neu...
متن کاملPeripheral Inflammation is Associated with Altered Substantia Nigra Activity and Psychomotor Slowing in Humans
BACKGROUND Systemic infections commonly cause sickness symptoms including psychomotor retardation. Inflammatory cytokines released during the innate immune response are implicated in the communication of peripheral inflammatory signals to the brain. METHODS We used functional magnetic resonance brain imaging (fMRI) to investigate neural effects of peripheral inflammation following typhoid vac...
