Reflex gelastic-dacrystic seizures following hypoxic-ischaemic encephalopathy.

Reflex or stimulus-sensitive epilepsies are uncommon epileptic syndromes triggered by exogenous-specific sensory stimulus or endogenous various mental activities. Gelastic-dacrystic seizures are rare epileptic manifestations characterised by ictal laughter and crying. Gelastic-dacrystic seizures are commonly caused by hypothalamic hamartoma but rarely described due to cortical dysplasia, lesions of frontal and temporal lobes, tumours and vascular malformations. We report a young woman who presented with somatosensory-evoked gelastic-dacrystic seizures. This patient had a positive history of perinatal insult substantiated by MRI findings. Hypoxic-ischaemic encephalopathy as the cause of gelastic-dacrystic seizures has not been reported so far in the literature.
