Bilingual effects of unilingual neuropsychological treatment of dyslexic adolescents: a pilot study.

Fourteen young adolescents with specific reading disabilities received short term neuropsychological treatment--specifically left hemisphere (LH) or right hemisphere (RH) stimulation--in a clinical pilot project. The effects on single-word and passage reading were evaluated when the language of treatment was either Dutch (mother tongue) or English (foreign language). Transfer effects across the two languages were also studied. In general, the results indicate that these short term interventions may prove successful for the treated language and with the additional transfer to a second (not treated) language.

Persistent cognitive defects after corrected hypothyroidism.

The authors present a case history in which cognitive defects caused by hypothyroidism persist after the patient has been rendered euthyroid. Concentration, recall and short-term memory appear to be most severely affected. The scarce literature on the subject is reviewed.

Outpatient treatment of dyslexia through stimulation of the cerebral hemispheres.

Although a number of experimental investigations into the effects of hemisphere stimulation on the reading performance of individuals with dyslexia are currently available, only a few studies have addressed the effects of treatment in the setting of an outpatient clinic. The present study reports on the reading results after a treatment that was based on the balance model and incorporated notions from cognitive psychological origin in 80 children with severe dyslexia who were referred to the outpatient clinic of the Paedological Institute in Amsterdam. Treatment was individually tailored, depending on the type of dyslexia, the phase of the learning-to-read process, and the intermediate results of treatment. Effects on reading performance, measured after preclinical (home-training), clinical, and postclinical intervention periods, were analyzed through multiple time-series and multilevel analyses. Treatment with flash cards, exercising automatic letter-sound conversions, appeared to have a robust and slight effect in the preclinical and clinical phases, respectively, whereas hemisphere stimulation produced robust effects in both the clinical and the postclinical period. The results are discussed in terms of theoretical models, experimental findings of other investigations, intellectual and scholastic characteristics of the subjects, and such treatment factors as compliance (see Note).
