Gait control and executive dysfunction in early schizophrenia.

Dysexecutive functioning, which is described as an enduring core feature of schizophrenia, has been associated with gait disorders. However, few studies have reported gait disorders in schizophrenia patients. The objective of this study was to examine the association between executive dysfunction and gait performance in recent-onset schizophrenia patients using the dual task paradigm.

Gait and motor imagery of gait in early schizophrenia.

Although gait disorders were described in schizophrenia, motor imagery of gait has not yet been studied in this pathology. We compared gait, motor imagery of gait and the difference between these two conditions in patients with schizophrenia and healthy age-matched controls. The mean ± standard deviation (S.

Frontotemporal dementia: pathology of gait?

The main diagnostic criteria of the behavioural variant of frontotemporal degeneration (bvFTD) include neurobehavioral and dysexecutive syndromes, but not specific gait characteristics although strong relationship between gait and prefrontal functions are increasingly recognized. Accordingly, we tested the hypothesis that patients with bvFTD would have more gait changes than older healthy controls and demented patients with Alzheimer's disease (AD). Sixty subjects were included in the study: 19 with bvFTD, 19 with AD and 22 healthy controls.

Agency, the sense of presence, and schizophrenia.

The objective of this work is to evaluate the impact of agency deficiency on presence. We hypothesize that a deficit in agency, such as occurs in schizophrenia, has repercussions on the sense of presence as well as on performance in a sensorimotor test involving the body. Nineteen healthy controls and 19 stable patients with schizophrenia, matched by age and gender, participated in the study.
