Multiple Dissociations in Patients With Disorders of Body Awareness: Implications for the Study of Consciousness

The existence of dissociations between anosognosia and neglect suggests that brain lesions selectivity affect conscious processes, rather than inducing general and global impairments in awareness.

Anosognosia and denial after right hemisphere stroke

This chapter will focus on anosognosia associated with right hemisphere stroke, that is mainly anos Cognosia for hemiplegia, and/or hemianopia.

Productive symptoms in right brain damage

The more recent studies on productive symptoms from the neuropsychological, neurophysiological and anatomical points of view are summarized to provide some clarifications on the cognitive impairments underpinning the main productive disorders, also contributing to better understand the normal functioning of the brain.

Motor awareness in anosognosia for hemiplegia: experiments at last!

It is concluded that the false experience of movement in AHP may provide insight into what occurs when the mechanism responsible for monitoring and correcting significant discrepancies between predicted and executed actions is impaired.

Motor awareness and motor intention in anosognosia for hemiplegia

It will be argued that anosognosia is due to the failure of a motor monitoring component that does not detect the mismatch between a desired action and the actual status of the sensorimotor system in face of an intact capacity of programming movements and forming Sensorimotor predictions.

Awareness of the Functioning of One's Own Limbs Mediated by the Insular Cortex?

The use of lesion mapping in 27 stroke patients is used to show that the right posterior insula is commonly damaged in patients with anosognosia for hemiplegia/hemiparesis but is significantly less involved in hemipLegic/hemIParetic patients without anos Cognosia, suggesting that the insular cortex is integral to self-awareness and to one's beliefs about the functioning of body parts.

Anosognosia for hemiplegia after stroke is a multifaceted phenomenon: a systematic review of the literature.

The need for a multidimensional assessment procedure for anosognosia following stroke is highlighted and some potentially productive directions for future research about unawareness of illness are suggested.

Unawareness of deficits after right hemisphere stroke: double‐dissociationsof anosognosias

Double‐dissociations demonstrate that anosognosias for different defects are independent and specific impairments of awareness, although general cognitive disorder may also reduce awareness of defects.

Dissociation of anosognosia for hemiplegia and aphasia during left-hemisphere anesthesia

V Videotapes of 54 patients with medically intractable seizures who had selective barbiturate anesthesia as part of their evaluation for seizure surgery were assessed for anosognosia of hemiplegia and aphasia after hemispheric anesthesia had worn off, providing support for the postulate that awareness of dysfunction is mediated by a modular system.

Blindsight and insight in visuo-spatial neglect

An analogous dissociation between overt and covert perception in a case of visuo-spatial neglect is reported, in which P.S. has a left homonymous hemianopia and neglect persists despite free movement of the head and eyes.
