Agnosia

Historical and Medical Background of Agnosia Agnosia is a rare neurological disorder that affects one’s capability to recognize people or objects based on the affected sense (Coslett, 2007; National Institute of Neurological Disorders and Stroke, 2014). There are three observed types of agnosia: Visual, Auditory, and Tactile (Coslett, 2007; Marotta & Behrmann 2002). Visual agnosia is the most common type because the brain devotes the most energy and resources to visual processing than processing

Visual form agnosia is defined as the inability to recognize objects (Goldstein, 2010). To understand the basic concept of visual form agnosia, it is important to first understand that perception and recognition are separate processes. Perception is defined as the ability to become aware of something through our senses, and recognition is the ability to put an object in a group that gives the item meaning. When a person suffers from visual form agnosia, they are generally able to identify the item

Congenital Visual Agnosia and Prosopagnosia in a Child In this paper I will be doing a literature review and evaluating the case study of a particular younger patient with Congenital Visual Agnosia and Prosopagnosia. Visual agnosia is the impairment of the recognition of different object stimuli, which cannot be explained by other sensory losses (Ariel, & Sadeh, 1996). There is said to be two different classifications or types of diagnosed visual agnosia, associate and appreciative agnosia (Ariel, & Sadeh

Agnosia is a loss of ability to recognize objects, persons, sounds, shapes, or smells. The specific sense is not defective nor is there any significant memory loss. It is usually associated with a brain injury or neurological illness. There are 3 forms of Agnosia: • Visual Agnosia. A person cannot recognize people or objects even though there is no abnormality of the eyes or the visual system. • Auditory Agnosia. A person cannot hear things such as words, environmental sounds or music, but can

I which takes into account clinical disorders, axis II looks at personality disorders, axis III diagnoses acute medical conditions, axis IV is psychosocial and environmental factors and axis V determines a person’s ability to function in society. Agnosia is one of the many disorders

going to evaluate and include Dr. Sacks conclusions on the case studies recorded in ‘Part One: Losses’. ‘Losses’ covers 9 neurological disorders which are characterised by a ‘loss’ of some kind. Dr. P, a musician and teacher who had developed visual agnosia, had difficulty processing what he sees, especially faces, he could only identify them by features which he remembered. He only completed tasks if he was singing, if interrupted, he could no longer remember what he was doing nor complete it. Sacks

Prosopagnosia is a neurological disorder that makes it difficult or virtually impossible for people to distinguish between human faces - in the worst cases, even the faces of close family members. There are obvious advantages to being able to recognize people, one of which is to distinguish between friends and enemies. Fortunately, most humans, especially infants, are able to do so with great ease. According to various studies, it seems that at the age of just a few months, infants begin to fine-tune

(2015) give a review on visual agnosia. These article’s main focus is on prosopagnosia. Sigmund Freud coined the term visual agnosia back in 1891. Visual agnosia is the ability to see an image and store it, but there is an impairment in visually recognizing the specific object. There are a plethora of subtypes of visual agnosia, which include prosopagnosia (the inability to recognize faces), achromatopsia (the inability to distinguish different colors), landmark agnosia (the inability to recognize buildings

Agnosia Agnosia is a neurological illness most often caused by dementia, strokes, or other neurological diseases but can also be the result of a trauma such as a head injury or infection. Sigmund Freud first proposed the term “Agnosia” in 1891 but, before then, Carl Wernicke, who discovered aphasia, was the first to have some of the ideas of what later became agnosia. In 1877, Kussmaul attempted to reveal the cause of Auditory Verbal Agnosia, commonly known as word deafness. Kussmaul believed

neurological disorder that is highlighted in chapter one is Visual Agnosia, which is a deficit associated with poor primary visual processing that affects shape perception, figures, object, face and letter recognition (Serino, et al., 2014). Other subtypes of visual agnosia that also seemed to fit the descriptions that Sacks shared is prosopagnosia, which is the inability to recognize human faces (Shah, 2016), and pantomime agnosia, characterized as the inability to understand gestures (Gonzalez,
