The presentation of John’s case, and the human aspects of the disorder, will also be of great interest to a general audience of lay people interested in perception. [psy.ox.ac.uk]

Martha Farah's landmark 1990 book Visual Agnosia presented the first comprehensive analysis of disorders of visual recognition within the framework of cognitive neuroscience, and remains the authoritative work on the subject. [worldcat.org]

  • Weakness

    Adrenal insufficiency leads to skin hyperpigmentation, weakness, loss of muscle mass and eventually coma. Impotence in males is common. Genetics This is an X-linked disorder secondary to mutations in the ABCD1 gene (Xp28). [disorders.eyes.arizona.edu]

    C.K. also had motor weakness on the left side and a left homonymous hemianopia. He recovered well, retaining normal intelligence and normal visual acuity. [en.wikipedia.org]

    Dyspraxia refers to difficulty performing motor acts which cannot be accountable by lack of understanding of the task, weakness, or proprioceptive loss. [jnnp.bmj.com]

  • Visual Impairment

    Patient WH WH, a 67-year-old, right-handed man, was admitted to the neurological department with a history of unspecific progressive “visual impairment” for several years affecting his reading abilities, object recognition, face perception and color discrimination [frontiersin.org]

    In apparent contrast to these severe visual impairments, he could move around safely in his neighborhood. For example, he took regular walks or went to the grocery store for daily shopping (using a written list handed over to the shop assistants). [jneurosci.org]

  • Hemianopsia

    A right homonymous hemianopsia was the only primary neurologic deficit, but there were specific behavioral disturbances. [jamanetwork.com]

  • Blurred Vision

    We report the case of a 34 year-old man who was admitted to hospital with seizures and a three-month history of headache, with blurred vision during the past month. A previous history of melanoma resection was obtained. [scielo.br]

    Signs of spatial neglect were not observed. T1- and T2-weighted magnetic resonance imaging of WH showed no signs of focal brain damage. [frontiersin.org]

  • Homonymous Hemianopsia

    A right homonymous hemianopsia was the only primary neurologic deficit, but there were specific behavioral disturbances. [jamanetwork.com]

  • Behavior Problem

    Younger patients tend to have more behavioral problems while older individuals may develop dementia. Adrenal insufficiency leads to skin hyperpigmentation, weakness, loss of muscle mass and eventually coma. Impotence in males is common. [disorders.eyes.arizona.edu]

The treatment for this clinical entity has focused primarily on compensatory training strategies and rarely includes neuropsychological rehabilitation. [medigraphic.com]

Standard Therapies Treatment Treatment of primary visual agnosia is symptomatic and supportive. Affected individuals may undergo exercises or rehabilitation to relearn about objects necessary for everyday living. [rarediseases.org]

Prognosis depends on the nature and extent of damage and patient age. There is no specific treatment, but speech and occupational therapy may help patients compensate. Agnosias are uncommon. [msdmanuals.com]

This form of agnosia doesn’t prevent you from being able to draw a picture of an object. [healthline.com]
