“…Young adults with acquired aphasia were shown to have slowed reaction times and a delay of certain components of evoked potentials in response to both non-verbal and phonological stimuli. The results contradict, to some extent, those obtained by Frumkin and Rapin (1980) and Notoya et al (1991) of poorer perception of consonants than of vowels. The findings would indicate that there is some degree of specificity of impairment within the auditory domain.…”

A case study is presented of a 14-year-old right-handed Caucasian female diagnosed with the Landau-Kleffner Syndrome (LKS) at the age 3 1/2 years. Her LKS symptoms presented with abrupt disruption in language after normal development, electroencephalogram (EEG) brain-wave abnormality, seizure activity, inability to read, and impairment in her motor skills. After 11 years of pharmacological and special education interventions with no significant improvement in any measurable area of function, a multimodal approach using techniques purportedly aimed at facilitating inter-hemispheric communication was provided. At completion of the program, EEG was controlled, reading, language, and auditory processing improved and objective behavioral-social measures improved significantly.

“…Young adults with residual LKS and acquired aphasia were shown to have slowed reaction times and a delay of certain components of evoked potentials in response to both nonverbal and phonological stimuli. The result contradicts, to some extent, those obtained by Frumkin and Rapin (1980) and Notoya et al (1991) of poorer perception of consonants than of vowels. This finding would indicate that there is some degree of selectivity of impairment within the auditory domain.…”

“…Thus, in the absence of severe oral apraxia, the basis for his recognition of the color words was probably the recognition of these vowel patterns. A relative facility of discriminating vowels as compared to consonants in LKS was previously reported by Frumkin and Rapin (1980) and Notoya et al (1991). In the phrases produced by V.N.…”

The Landau-Kleffner Syndrome (LKS) is characterized by acquired receptive aphasia and EEG abnormality with onset between the ages of 3 and 8 years. This study presents neuropsychological assessments in 5 children with LKS. The aims were (1) to specify the neuropsychological deficits characteristic of these children; and (2) to clarify the nature of the receptive aphasia by comparing nonverbal and verbal auditory discrimination. Receptive aphasia was present in all children. Retardation, poor motor coordination, hyperkinesia, and conduct problems were frequent but variable. All children exhibited a dissociation between the discrimination of environmental sounds and phonological auditory discrimination, the latter being more impaired than the former. This suggests that the primary deficit of the receptive aphasia is an impairment of auditory phonological discrimination rather than a generalized auditory agnosia. (JINS, 1998, 4, 566-575.)

“…Most of them researched patients with pure word deafness (Albert & Bear, 1974;Auerbach, Allard, Naeser, Allexander, & Albert, 1982;Notoya, Suzuki, Furukawa, & Enokido, 1991;Tanaka, Yamadori, & Mori, 1987;Saffran, Marin, & Yeni Komshian, 1976;Caramazza, Berndt, & Basili, 1983). Albert and Bear (1974) and Auerbach et al (1982) emphasized that the defect in auditory temporal resolution played an important role for the development of pure word deafness.…”

“…They found that patients with pure word deafness were markedly impaired in detecting gaps between acoustic stimuli. Notoya et al (1991) and Tanaka et al (1987) suggested that besides this deficit, the difficulties in loudness discrimination and pitch discrimination may also cause word deafness. These authors have emphasized defects in acoustic level as the underlying defect in pure word deafness.…”
