Stereognosis is the ability used to identify objects using only tactile sensory information, or when in the absence of visual or other sensory information to identify the object. Astereognosis, often called tactile agnosia if occurring in only one half of the body or one hand, is the inability to identify objects by handling them despite otherwise intact elementary tactile, proprioceptive (awareness of one’s own body position) and thermal sensations (Elias & Saucier, 2014, p. 166). In other words, individuals who suffer from astereognosis are unable to identify what is placed in their hands based only on cues such as texture, size, spatial properties or materials (or at least have great difficulty with this ability) and typically require sight …show more content…
268). This disorder is often a result of damage to one or more of these areas, illustrating the complex, separate systems involved in perceiving, integrating, and making observations on this information, as well as the possibility for these systems to become altered or interrupted as a result of lesions, tumours, or other forms of damage. It is also worth noting that those suffering from Alzheimer’s or other forms of dementia show a reduction in their stereognosis ability, showing that some neurological diseases may impact these systems as well (Gerstmann, 2001, p. 271). Apart from the impact on making associations between previously perceived objects and immediate tactile sensory input, individuals with this disorder would rarely experience significant distress or impact to their quality of life as it does not directly affect interactions with others or their …show more content…
In this way, astereognosis affects the accuracy, speed, and focus of the individual in the performance of fine motor skills or perceptions, so issues in the workplace or occupational setting would be the most common for these individuals. Here, we see how intently individuals with astereognosis must pay attention when searching for and selecting tools for use, often leading to delays in performance. This is because they cannot use tactile information alone to perceive and often rely on visual confirmation, creating an extra step that most people do not require. This diary piece is useful for showing how one’s speed may be affected at work – if an individual is constantly having to look away from something to confirm their hands are touching the right place, or if they must intently inspect an object before selecting, they will be slower in performance in comparison to others not experiencing these
Agnosia will affected the patients to lose the ability to know or recognize or diffrentiate the meaning of stimuli even with intact senses. We know that agnosia could happen to every stage of human life. There many type of agnosia, such as when someone cannot recognize faces that sickness call prospagnosia. Then when we lost ability to observe facial expression or body language, this problem is defines as social emotional agnosia. Tactile agnosia is one of a type of agnosia which refer to the cognitive abilities. This problem happen when someone loses ability to process the meaning from touches senses.
The symptoms of a right-hemisphere stroke are very much similar like the symptoms Mr. Fix-it is experiencing. For example, both suggest that functions on the left side of the body are completely neglected; therefore, the left visual section of the body does not respond effectively to stimuli due to the neglect. Damage to the right occipital lobe is very likely. The patient may have experienced some damage to areas 18 and 19 of the occipital lobe. “Damage to these association areas resulted in the patient’s failure to recognize items even when they have been seen before”, such as Mr. Fix-it’s deficiency to recognize geometric shapes (Carlson, 2010). Moreover, the patient could have also experience damage in the frontal lobe, specifically on area 8, in which it could have r...
The criticism that sensory integration therapy faces is that there is not enough information resulting in a success rate. If there are no tangible results, why would parent’s waste time and money on this type of therapy is a question that the occupational therapy community faces. Sensory processing disorder has no real diagnosis as well, since there is such a broad spectrum. The symptoms of sensory processing disorder are also vague. This perplexing clinical concern is apparent to Zimmer, “It remains unclear whether children who present with findings described as sensory processing difficulties have an actual “disorder” of the sensory pathways of the brain or whether these deficits represent differences associated with other developmental and
Asperger syndrome belongs to a group of childhood disorders commonly known as pervasive developmental disorders or PDD's. The disorder is recognized as a less severe case of autism. Children who have the disorder have a difficult time in social settings but excel in other areas of inteligence. The disorder is usually a lifelong struggle but has few cases where the patent recovers in adulthood. The disorder is not widely understood by the population but it is becoming a more well known disorder. There is currently no cure for this disorder.
In the 1940’s two doctors in different countries observed children displaying similar behaviors and deficits. One of the doctors was Viennese pediatrician Dr. Hans Asperger and the other was a child psychiatrist named Leo Kanner. Dr. Kanner was the first of the two doctors to report his observations. What he described were behaviors similar to those seen in children with what we call Autistic disorder. The behaviors affected the children’s communication, social interaction and interests. Dr. Asperger later published an article discussing what he dubbed “Autistische Psychpathen im Kindesalter” which translates to “Autistic Psychopathy”. Although some behaviors overlapped, there were differences leading to the belief that these doctors were documenting two different disorders. The two most prevalent were the differences in motor and language abilities (Miller, Ozonoff). Another was Asperger’s belief that his patients were of normal or above average intelligence. It was not until 1994 that Asperger Syndrome was entered into the Diagnostics and Statistics Manual of Mental Disorders Fourth Edition (DSM IV), finally becoming an official diagnosis. At the time, Asperger Syndrome (AS) was labeled as a subcategory of autism along with autistic disorder, childhood disintegrative disorder and pervasive development disorder. Since then, the community of people with Asperger Syndrome has grown to love and better understand the disorder that they live with every day. Some of them have even affectionately named themselves “Aspies”.
Cognitive tempo/reflectivity v impulsivity: whether people prefer to take in and process information quickly or more slowly with greater or less informational input and greater /less concern for accuracy.

Motor impairments are one of a large number of concerns for children who are diagnosed with ASD. These motor impairments can be quite diverse and include impairments that affect the individual with ASD’s gross and fine motor skills and control of posture (Bhat, Landa, & Galloway, 2011). There is research reflecting that eighty-three percent of children with ASD demonstrate below average functioning on various motor-skill related tests. These motor impairments can affec...
Visual agnosia is a neurological disorder characterized by the inability to recognize familiar objects (Farah, 1990). Object recognition is the ability to place an object in a category of meaning. Most cases of visual agnosia are brought about through cerebral vascular accidents or traumatic brain injury typically inhibiting sufficient amounts of oxygen from reaching vital body tissues (Zoltan, 1996). There are a vast array of impaired abilities and deficits associated with individuals diagnosed with visual agnosia. These impairments vary considerably from individual to individual (Farah, 1990). Some patients cannot recognize pictures of things such as trees and birds, despite being able to describe such objects or recognize them through other senses such as sound and touch. Other patients demonstrate an inability to recognize faces of friends and family members (Goodale, 1995). The functional impairments experienced as a r...
Pervasive Developmental Disorders are characterized by “severe and pervasive impairment in several areas of development” (Tsai, 1998). In the 1994 edition of the Diagnostic Statistic Manuel version IV, three new categories were introduced under Pervasive Developmental Disorders. These include: Childhood Disintegrative Disorder, Asperger's Disorder, and Rett's Syndrome (Volkmar, 2005). All these disorders occur in early childhood and are often not noticed by a parent or primary caregiver until it is noticed that the child is not achieving normal developmental milestones.
Dr. Hans Asperger was the first to describe Asperger’s Syndrome, also known as AS, in 1944. He explained that AS causes clumsiness, poor motor skills, and an inability to walk or run smoothly (Miyahara, Tsujii, ...
Imagine a world where numbers, letters, tastes, and sounds have color. Imagine a world where letters and numbers have personalities. For a synesthete, this is their world. Synesthesia occurs from a cross wiring in the brain. Instead of one sense being used in a particular action, multiple senses are used. Although little medical knowledge is known about the condition, it is fascinating and continues to impact our world.
Sensory processing disorder is a neurological disorder that interrupts the way a person processes and responds to the sensations. Research has shown that between 5-17 percent of the population
In simpler terms, “people with ASDs handle information in their brain differently than other people” (Centers for Disease Control and Prevention). A quantity of social and behavioral symp...
There are many symptoms of depersonalization that patients with this disorder have to deal with. J.C. Dixon studied the symptoms of DPD and found many recurring ones that people explained they had. Examples of this were: other people seemed changed or unfamiliar, things a person was used to seemed strange, body seemed detached, no self- awareness, and no difference between self and not-self (Trueman 2). These are not the only symptoms, another one is a type of obsession, like OCD. A patient may resort to obsessing over their symptoms. They may keep looking at their hands to decide if they look any more or less real than an hour ago, or may repeatedly check hundre...
