“…Abnormalities commonly found in the EEG compatible with CH consisted of generalised or focal slow waves, epileptiform activity, asynchronous and asymmetrical spindles, or alterations of the background rhythm activity 2 6 7. Likewise, these results are similar to the alterations found in human beings 11.…”

Congenital hydrocephalus is a neurological disorder frequently observed in dogs. It is characterised by an increase of cerebrospinal fluid volume in the ventricular system that can cause atrophy of brain tissue. It can be provoked by diverse causes, as it can be idiopathic or secondary to nervous system abnormalities. Diagnosis is based on clinical signs and imaging studies, but neurophysiological techniques can provide valuable information. This report describes functional changes in the brain and brainstem evaluated by electroencephalogram and auditory evoked potentials. In the three cases, the authors found alterations in background rhythm, slow waves, epileptiform activity, hypsarrhythmic tracing and positive sharp waves. These techniques allow detecting alterations in the brain bioelectrical activity that do not trigger clear clinical responses.

“…Electroencephalography is a non-invasive investigation with no adverse effects, it is not cost-prohibitive as the CT or MR and it allows one to assess the impact of the hydrocephalus on the electrical activity of the brain. Until now, electroencephalographic patterns in congenital hydrocephalus have been well described in human medicine, and only few studies have been reported in dogs (Prynn and Redding 1968;Klemm and Hall 1971;Klemm and Hall 1972;Okurowska-Zawada et al 2007;Armasu et al 2014). To our knowledge, the electroencephalographic patterns in sheep affected by hydrocephalus have been described only in one case (Masucci et al 2012).…”

The clinical, electroencephalographic and neuro-pathological features of three cases (cases 1, 2 and 3) of congenital hydrocephalus in sheep were described. The observed neurological signs reflected damage in the telencephalon and brain stem. The electroencephalogram performed in case 1 and case 2 showed different patterns: symmetric and synchronous high-voltage slow-activity in case 1, and low-voltage slow-activity in case 2. By the post-mortem examination, in all the animals, dilatation of the ventricular system, especially of the lateral ventricles, associated with a glial reaction surrounding the dilated ventricles was observed. Only in case 3, a monolateral meningeal thickening at the left cerebellopontine angle seemed to be responsible for the obstructive hydrocephalus. In the other two brains (case 1 and 2), no potential anatomical cause for the hydrocephalus were detected, even if, in case 2, a compensatory form was not excluded due to the moderate hypoplasia of the cerebrum and the presence of the non-suppurative inflammation. The results of this work provide a contribution to the EEG characterisation in ovine hydrocephalus cases; nevertheless further multidisciplinary studies of a larger number of sheep could permit to better characterise the EEG pattern in ovine hydrocephalus cases.
