This investigation assessed the effectiveness of a phonological intervention program on the brain functioning of bilingual Finnish 6- to 7-year-old preschool children diagnosed with specific language impairment (SLI). The intervention program was implemented by preschool teachers to small groups of children including children with SLI. A matched group of(More)
PURPOSE To study the prevalence and features of visual field constrictions (VFCs) associated with vigabatrin (VGB) in children. METHODS A systematic collection of all children with any history of VGB treatment in fifteen Finnish neuropediatric units was performed, and children were included after being able to cooperate reliably in repeated visual field(More)
The sudden infant death syndrome has multiple etiologies. Some congenital myasthenic syndromes can cause sudden infant death syndrome by apnea, but the frequency of this etiology is unknown. We report here a young patient with sudden respiratory crises culminating in apnea followed by recovery, against a background of no or variable myasthenic symptoms(More)
EEG evoked potentials were studied in 23 young adolescent poor spellers and 21 controls. Findings typical of poor spellers were long auditory evoked potential (AEP) latencies and low amplitudes of early AEP deflections. A high frequency of spelling errors concerning the word as a whole was associated with low AEP P50 and P300 amplitudes. Poor reading was(More)
A total of 23 13-year-old boys with spelling disabilities and 21 matched controls were studied. EEG was recorded for visual and quantitative analysis, including FFT band powers and normalized slope descriptors (NSD). Visual analysis showed general excess of slow activity, as well as an excess of temporal slow wave activity in the index group. Quantitative(More)

Twenty-three poor spellers (average age 13 years) and 21 matched controls were studied. The EEG from 6 derivations was quantified using Hjorth's parameters 'Activity' and 'Mobility,' from which product-moment correlations were calculated between derivations. Cross-correlations were analogously calculated from EEG amplitude values. In poor spellers higher(More)
OBJECTIVE Our objective was to study how well the auditory evoked magnetic fields (EF) reflect the behavioral discrimination of speech sounds in preschool children, and if they reveal the same information as simultaneously recorded evoked potentials (EP). METHODS EFs and EPs were recorded in 11 preschool children (mean age 6 years 9 months) using an(More)
Specific language impairment (SLI) is diagnosed when a child has problems in producing or understanding language despite having a normal IQ and there being no other obvious explanation. There can be several associated problems, and no single underlying cause has yet been identified. Some theories propose problems in auditory processing, specifically in the(More)
A follow-up study of 26 dyslexics with an age range from 20 to 28 years revealed that reading and writing problems were essentially unchanged from the time of diagnosis 7-10 years earlier. The intellectual capacity of all subjects was normal. One of the ten who finished high school had started university studies. Sixteen (62%) had completed only the(More)
AIM There is little data on whether or not a bilingual upbringing may aggravate specific language problems in children. This study analysed whether there was an interaction of such problems and simultaneous bilingualism. METHODS Participants were 5- to 7-year-old children with specific language problems (LANG group, N = 56) or who were typically(More)
