Epilepsy in Shunted Posthemorrhagic Infantile Hydrocephalus Owing to Pre- or Perinatal Intra- or Periventricular Hemorrhage

Epilepsy is relatively common in infants with hydrocephalus. Its mechanism is controversial; in fact, studies on etiologically heterogeneous series are not able to clarify the mechanism generating epilepsy or to suggest effective prevention and treatment strategies. Our study is aimed at assessing the onset and evolution of epilepsy, as well as concurrent cognitive development of a homogeneous series of shunted posthemorrhagic hydrocephalus owing to pre- or perinatal intra- or periventricular hemorrhage. Forty patients were enrolled in the study. Twenty-six were patients with grade II-III intraventricular hemorrhage, 16 of whom had associated ischemic lesions. In the remaining 14 patients, a grade IV intra-ventricular hemorrhage was found. Epilepsy was observed in 27 patients. Aside from 10 cases with nonsyndromic forms of epilepsy, it was possible to define at least three different age-dependent epileptic syndromes: symptomatic neonatal location-related epilepsy with transient West's syndrome in infancy in 5 patients; West's syndrome in 8 patients; and continuous spike-waves during sleep in 4 patients. Epilepsy was significantly correlated with ischemic lesions only. Early thalamic injuries frequently evolved toward continuous spike-waves during sleep, indicating that patients with thalamic injury must be monitored to detect continuous spike-waves during sleep early. Cerebellar atrophy, in addition to epilepsy and other brain injuries, accounted for disorders of cognitive development.

Ten cases of epilepsy with continuous spike waves in slow-wave sleep (CSWS) were evaluated using single photon emission computed tomography (SPECT); in eight patients the EEG paroxysmal abnormalities showed a predominant localization. SPECT carried out using 99mTc-HMPAO allows study of cerebral blood flow (CBF); the examination was performed during phases of drowsiness and the results compared to the EEG data. In four cases SPECT revealed areas of low CBF in sites corresponding to those of the prevalent EEG discharges; in two cases the areas of hypoperfusion did not correspond to those indicated by the EEG; lastly, in four cases SPECT results were negative. The areas of hypoperfusion were predominantly located in the frontal, temporal, and parietal regions. Furthermore, the percentage of positive SPECT results was significantly higher (five cases out of six) in the group in which the CSWS phase was prolonged for at least 1 year, compared to the group in which this phase lasted less than 1 year. Thus, in this type of epilepsy, SPECT reveals focal cortical areas of decreased CBF which correlated generally to the predominant sites of EEG abnormalities. A longer duration of the CSWS phase seems to be associated with a more significant cortical disorder, documented by the presence of areas of hypoperfusion.
