They also lacked nonverbal communication skills and were physically clumsy. Asperger described this "autistic psychopathy" as social isolation. Fifty years later, several standardizations of AS as a medical diagnosis were tentatively proposed, many of which diverge significantly from Aspergers original work.Unlike todays AS, autistic psychopathy could be found in people of all levels of intelligence, including those with intellectual disability. Asperger defended the value of so-called "high-functioning" autistic individuals, writing: "We are convinced, then, that autistic people have their place in the organism of the social community. They fulfill their role well, perhaps better than anyone else could, and we are talking of people who as children had the greatest difficulties and caused untold worries to their care-givers." Asperger also believed some would be capable of exceptional achievement and original thought later in life.Aspergers paper was published during World War II and in German, so it was not widely read elsewhere. Lorna Wing used the term Asperger syndrome in 1976, and popularized it to the English-speaking medical community in her February 1981 publication of case studies of children showing the symptoms described by Asperger, and Uta Frith translated his paper to English in 1991. Sets of diagnostic criteria were outlined by Gillberg and Gillberg in 1989 and by Szatmari et al. in the same year. In 1992, AS became a standard diagnosis when it was included in the tenth edition of the World Health Organizations diagnostic manual, International Classification of Diseases (ICD-10).
This procedure should only be performed if it will eliminate the lameness associated with navicular syndrome, and only after all other options have been explored. The procedure is usually performed on both front feet. Complications can include infection of the wound, continuation of the lameness (if the nerves regrow or if small branches of the nerves are not removed), neuromas, and rupture of the deep digital flexor tendon. After the neurectomy, if the horse becomes injured in the area the injury may go undetected for a long period of time, which risks the animals health. Due to this, the feet should be cleaned and inspected regularly. Neurectomy tends to lower the market value of a horse, and may even make the horse ineligible for competition. Neurectomy is controversial. The most common misconception about "nerving" a horse is that it will permanently solve the lameness/pain issue. In fact, though the time periods vary based on the individual horse and surgical method utilized, these nerves often regenerate and return sensation to the afflicted region within two to three years. In navicular suspensory desmotomy, the ligaments supporting the navicular bone are severed. This makes the navicular bone more mobile, and thus reduces the tension of the other ligaments. It is successful about half of the time. Prognosis
The prognosis for a horse with navicular syndrome is guarded. Many times the horse does not return to its former level of competition. Others are retired.
