Hypothalamic hamartomas (HHs) are congenital malformations of the ventral hypothalamus resulting in treatment-resistant epilepsy and are intrinsically epileptogenic for the gelastic seizures that are the hallmark symptom of this disorder. Gelastic epilepsy without HH has a more benign evolution. January 2010; DOI: 10.1007/978-1-84882-128-6_134. Sex Twice as many males as females. Since 2002, department Pediatric Neurosurgery of Xinhua Hospital has maintained a multidisciplinary clinical program to evaluate and treat children with HH. Ictal/interictal EEG and magnetic resonance imaging were performed. Introduction The characteristics of epileptic seizures can sometimes indicate their origins within the brain. Hypothalamic hamartomas are associated with the remarkable phenomenon of gelastic (laughing) seizures often accompanied by a severe and medically refractory epilepsy syndrome. Age at onset Neonatal period or early childhood; peak at 2 to 3 years. Age at onset Neonatal period or early childhood; peak at 2 to 3 years. Gelastic seizures often are the earliest seizure type manifested by patients with hypothalamic hamartomas, often during the first days of life. This report describes gelastic seizures in patients with optic nerve hypoplasia and hypothalamic dysfunction without hypothalamic hamartoma. Seizures may begin at any age, but usually before 3 or 4 years of age. A person may experience seizures at any age, although usually prior to 3 … Hypothalamic hamartoma (HH) is a rare developmental malformation often characterized by gelastic seizures.

Clinically, most patients with hypothalamic hamartomas suffer from precocious puberty, gelastic (laughing) epilepsy, as well as other types of convulsions and behavioral abnormalities (3, 48, 65). The hamartoma itself is generally considered benign and does not need treatment from a tumor perspective. Objectives: The objective of this study was to describe the clinical characteristics and surgical outcome in patients with gelastic seizures without hypothalamic hamartoma.

Without surgical intervention, most of gelastic seizures may pro-gress to other seizure types such as tonic, myoclonic, or secondarily generalized seizures [7]. The seizures usually start with laughter. Common symptoms include frequent gelastic seizures (spontaneous laughing, giggling … Seizures. What is hypothalamic hamartoma? Results: Five patients were affected by symptomatic localization‐related epilepsy (LRE), with four of the patients' disorders related to a hypothalamic hamartoma (HH) and one to tuberous sclerosis (TS) without evident hypothalamic lesions. [4] History Seizures may begin at any age, but usually before 3 or 4 years of age. Both the type and severity of symptoms vary greatly among patients with hypothalamic hamartomas. author = "S.
