Undoubtedly unaware of homonymous hemianopia: The contribution of overconfidence to anosognosia of hemianopia. A new functional deficit caused by a stroke can be understood as a situation of uncertainty that has to prompt deficit discovery…

Illusory hand movements in the absence of asomatognosia, spatial neglect and anosognosia for hemiplegia

Cortex · auteur h-index 31 · 4 citations

Anosognosia in Alzheimer's disease (AD) is defined as a lack of awareness for cognitive deficits or severity of disease. Previous studies have highlighted the link between anosognosia and damage to prefrontal functioning, i.e., executive fu…

According to neuropsychological models of anosognosia, there is a failure to transfer on-line awareness of dysfunction into a more generalised long term belief about memory function in Alzheimer's disease. This failure results in specific m…

A case of somatoparaphrenia characterized by very mild somatosensory disturbance and absence of anosognosia for hemiplegia and personal neglect

Cortex · auteur h-index 21 · 4 citations

Anosognosia for memory loss is a common feature of Alzheimer's disease (AD). Recent theories have proposed that anosognosia, a disruption in awareness at a global level, may reflect specific deficits in self-monitoring, or local awareness.…

Anosognosia for hemiplegia is a lack of awareness of motor deficits following a right hemisphere lesion. Residual forms of awareness co-occur with an explicit denial of hemiplegia. The term emergent awareness refers to a condition in which…

Mood-congruent recollection and anosognosia in Alzheimer's disease. The aim of the study was to investigate experimentally the impact of current mood state on anosognosia or awareness of symptoms in AD patients, in which mood state was mani…

Disordered awareness of memory loss (i.e., anosognosia) is a frequent and clinically relevant symptom of Alzheimer's disease (AD). The metacognitive errors which characterize anosognosia in AD, however, have not been fully articulated. The…

Anosognosia for hemiplegia (AHP) is informative about the neurocognitive basis of motor awareness. However, it is frequently associated with concomitant symptoms, such as hemispatial neglect and disturbances in the sense of body ownership (…

Anosognosia for hemiplegia has seen a century of almost continuous research, yet a definitive understanding of its mechanism remains elusive. Essentially, anosognosic patients hold quasi-delusional beliefs about their paralysed limbs, in sp…

Introduction At the centenary of research on anosognosia, the time seems ripe to supplement work in anosognosic patients with empirical studies on nosognosia in healthy participants. To this end, we adopted a signal detection framework to i…

Every movement begins with action programming, and ends with a produced effect. Anosognosia for hemiplegia (AH), involving unawareness of motor deficits after brain damage, is a striking but also poorly understood symptom in clinical neurol…

Right brain damage patients may not complain of a left sided paralysis up to the point of denying it or even claiming of having just moved an otherwise paralyzed limb. This condition is known as anosognosia for hemiplegia (AHP). Recent beha…

Brain-damaged patients affected by hemianaesthesia (i.e., the loss of tactile sensibility on the contralesional side of the body) may deny their deficits (i.e., anosognosia for tactile deficits) even reporting tactile experience when stimul…

Disturbances of self-awareness are observed in a wide variety of patients. While group studies can provide useful information concerning potential mechanisms underlying these complex disturbances, experienced clinicians, such as Babinski, r…

Anosognosia is present in a large proportion of patients with mild Alzheimer's disease (AD), and its frequency increases with the progression of the illness. Several instruments have been validated to assess anosognosia in AD, but there is…

Right-brain-damaged patients with unilateral spatial neglect are usually unaware (anosognosic) about their spatial deficits. However, in the scientific literature there is a lack of systematic and quantitative evaluation of this kind of una…

The affective modulation of motor awareness in anosognosia for hemiplegia: Behavioural and lesion evidence. The possible role of emotion in anosognosia for hemiplegia (i.e., denial of motor deficits contralateral to a brain lesion), has lon…

The construction of anosognosia as a clinical 'disorder' resulted from the convergence (in the work of various writers and culminating in Babinski) of a name, a concept, and a clinical phenomenon. During the early stages of this convergence…

In patients with left-sided lesions, anosognosia for hemiparesis (AHP) seems to be a rare phenomenon. It has been discussed whether this rareness might be due to an inevitable bias due to language dysfunction and whether the left hemisphere…

Unawareness of hemiplegia was first called anosognosia by Babinski one century ago. This paper reviews some of the major theories that may account for this disorder. Weinstein and Kahn posited that anosognosia was a psychological defense me…

Anosognosia is a multifaceted, neuro-psychiatric syndrome characterized by defective awareness of a variety of perceptuo-motor, cognitive or emotional deficits. The syndrome is also characterized by modularity, i.e., deficits of awareness i…
