ABSTRACT
Supporting data from the literature, we observe that large arachnoid cysts may affect cognitive function. Neuropsychologic assessment plus magnetic resonance imaging allowed for documentation of associations between left temporal arachnoid cysts, language impairment, and other cognitive dysfunctions. Significant cognitive improvements were evident soon after cysto-peritoneal shunting. These observations reinforce the rationale for neuropsychologic assessments of patients with developmental delay and arachnoid cysts, and support the potential benefit of surgical decompression for arachnoid cysts associated with neurologic deficits, even if surgery is performed well after the occurrence of neurologic deficits.

The aim of this study was to further define the clinical features of subcortical aphasia in children with deep brain infarcts and to define the sequelae associated with childhood strokes. We retrospectively studied nine children with left subcortical brain infarcts who presented with acquired language disorder and underwent language investigations based on standardized tests. Stroke in these patients involved the left internal capsule, lenticular or thalamic nuclei, or a combination of these. Early aphasic manifestations following the deep cerebral infarcts affected language expression. These included mutism, nonfluent speech, word finding difficulties, and phonemic and semantic paraphasia. Speech comprehension was generally more preserved. All patients subsequently improved, although variably; sequelae such as dysfluency, word finding difficulties, and written language learning impairment could be detected through standardized tests in six of them (all younger than 6 years at the time of the infarct). Two of the three remaining patients (both older than 6 years at the time of the infarct) had a full recovery. Our study confirms the concept of childhood subcortical aphasia, depicts the linguistic profile in these patients, and sustains the indication of systematic formal language assessment during the follow-up of all children with subcortical infarct involving the dominant hemisphere.

This study was undertaken to determine the effect of antiepileptic treatment on a child with attention-deficit-hyperactivity disorder and subclinical electroencephalographic discharges without seizures. We performed a longitudinal follow-up study correlating clinical, neuropsychologic, and electroencephalographic features with antiepileptic drug therapy. The results revealed a temporal relation between subclinical epileptiform discharges and cognitive dysfunction and a significant effectiveness of antiepileptic drugs on attention-deficit-hyperactivity disorder and electroencephalographic discharges. The practice of monitoring antiepileptic treatment limited to seizure control should be revised; cognitive impairments also need to be taken into account even without occurrence of seizure. The classical principle of treating only seizures needs to be reconsidered.
