Although traditionally used electronystagmographic positional and caloric parameters were not similarly discriminating, quantitative measures of vertical nystagmus in various eyes-closed positions appeared to have diagnostic potential and were related significantly to such CV-determined neurological signs as positive monopedal Romberg. As a substantial majority of learning disabled (82.9%) evidenced ADD-like symptoms and since learning disabled subsamples with and without Attention Deficit Disorder (ADD) shared similar coexisting symptoms and CV signs, it appeared probable that learning disabilities and ADD were reflections of the same underlying CV determinants.<\/jats:p>","DOI":"10.2466\/pms.1990.71.1.67","type":"journal-article","created":{"date-parts":[[2011,8,31]],"date-time":"2011-08-31T19:27:50Z","timestamp":1314818870000},"page":"67-82","source":"Crossref","is-referenced-by-count":15,"title":["The Diagnostic Value of Cerebellar-Vestibular Tests in Detecting Learning Disabilities, Dyslexia, and Attention Deficit Disorder"],"prefix":"10.1177","volume":"71","author":[{"given":"Harold N.","family":"Levinson","sequence":"first","affiliation":[{"name":"New York University Medical Center"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1990,8,1]]},"reference":[{"key":"bibr1-pms.1990.71.1.67","volume-title":"Sensory integration and learning disorders","author":"Ayres A.
