          Abstract

          Anton's syndrome is arguably the most striking form of anosognosia. Patients with this syndrome behave as if they can see despite their obvious blindness. Although best known for his description of asomatognosia and visual anosognosia, Gabriel Anton (1858-1933) made other significant contributions to the clinical neurosciences, including pioneering work in neurosurgery, neuropsychology, and child psychiatry. However, it has not been recognized in the English literature that Anton was also a dedicated advocate of eugenics and racial hygiene. This paper provides a case of Anton's syndrome and puts the works of Gabriel Anton into their historic context.

          The incidence of neglect phenomena and related disorders in patients with an acute right or left hemisphere stroke.

          We studied 171 consecutive patients with an acute hemispheric stroke (69 right hemisphere, 102 left), at 2-3 days post-stroke. A standardized test battery, previously validated in patients with acute stroke, was used to detect a wide variety of neglect phenomena and related disorders. Visual neglect was found in 82% of assessable right hemisphere patients and 65% of left hemisphere patients. Hemi-inattention was found in 70% of right and 49% of left hemisphere strokes. Tactile extinction was found in 65% of right and 35% of left hemisphere patients; allaesthesia in 57% (right), and 11% (left); visual extinction in 23% (right) 2% (left). Anosognosia was found in 28% (right), and 5% (left); anosodiaphoria in 27% (right), and 2% (left); non-belonging in 36% (right) and 29% (left). Visual neglect occurred more commonly in left hemisphere stroke than previously reported. Although neglect phenomena and related disorders were associated with right hemisphere damage, it is possible that language difficulties obscured their presence in some patients with a left hemisphere stroke.

              Visual neglect.

              Left visual neglect is a frequent and dramatic consequence of right hemisphere lesions. Diagnosis is important because behavioural and pharmacological treatments are available. Furthermore, neglect raises important issues concerning the brain mechanisms of consciousness, perception and attention. Recent behavioural findings and new techniques, such as transcranial magnetic stimulation, direct cortical and subcortical stimulation during brain surgery, and diffusion tensor imaging tractography, have provided evidence relevant to the debate concerning the functional mechanisms and the anatomical bases of neglect. Several component deficits appear to interact in producing different forms of neglect. Rather than lesions at single cortical levels, dysfunction of large-scale brain networks, often induced by white matter disconnection, may constitute the crucial antecedent of neglect signs.
