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.

Denial of Illness

This chapter first reviews the most common forms of anosognosia for different domains of deficits and then focuses on denial of hemiplegia, suggesting a role of multiple component deficits affecting not only motor control, attention, or proprioception but also emotional and self-monitoring systems implicated in error detection as well as belief formation and updating.

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.

Assessing anosognosia: a critical review

This manuscript critically review the literature on the assessment of anosognosia, mainly focusing on motor and language deficits, with a note on the issue of awareness for memory deficits.

Anosognosia for prospective and retrospective memory deficits: Assessment and theoretical considerations.

A new method of assessment provided by the VATAmem reduced possible false positives and enhanced reliability, and it is concluded that careful consideration of methodology is a key step to interpreting anosognosia findings within a theoretical framework.

The Petrified Self 10 Years After: Current Evidence for Mnemonic anosognosia

Empirical evidence is given to empirical evidence produced on anterograde memory deficits about performance, the profile of autobiographical retrograde memory loss and the role of frontal lobes in anosognosia in AD.

Metacognitive theory and assessment in dementia: Do we recognize our areas of weakness?

It is argued that metacognitive techniques used in healthy adults, such as the Feeling of Knowing task, offer models for dissecting awareness into clear and identifiable cognitive components in patients with AD, and critique several studies that have pioneered such tasks in AD.

The terms anosognosia and impaired awareness of deficit synonymously are used, although it is recognized that these and other terms used within the relevant literature can reflect differing connotations and theoretical commitments.



Chronic anosognosia: a case report and theoretical account

Anosognosia for hemiplegia, neglect dyslexia, and drawing neglect: Clinical findings and theoretical considerations

Abstract In this paper different models of anosognosia are confronted and data concerning denial behaviors are presented that were collected on a selected population of right brain-damaged patients

Unawareness of deficits in neuropsychological syndromes.

An integrative theoretical framework is proposed to account for unawareness of deficits in diverse neuropsychological syndromes and possible directions for future research are outlined.

The pathogenesis of anosognosia for hemiplegia

The pathogenesis of anosognosia for hemiplegia may involve failure to discover paralysis because proprioceptive mechanisms that ordinarily inform an individual about the position and movement of limbs are damaged, and the patient, because of additional cognitive defects, lacks the capacity to make the necessary observations and inferences to diagnose the paralysis.

Denial of hemiplegia: an investigation into the theories of causation.

Patients with denial of hemiplegia following acute CVA have significantly more white matter involvement, particularly the corona radiata, than those with neglect and there was also a trend that patients with denial are more likely to have lesions in the caudate.

The syndrome of anosognosia.

Most of the discussion has centered about whether a focal lesion can produce anosognosia or whether diffuse involvement of the brain is necessary.

Motivational and structural factors in the denial of hemiplegia.

Two somewhat separate approaches can be identified in the effort to arrive at a unified point of view concerning the symptomatology of patients with anosognosia.

A prospective study of 20 consecutive patients with organic delusions revealed four general types of false beliefs: simple persecutory delusion, complex persecutory delusions, grandiose delusions, and those associated with specific neurological defects (anosognosia, reduplicative paramnesia).
