Autism is a developmental disorder characterized by impairments in social and communication abilities, as well as by restricted and repetitive behaviors. Incidence of autism is higher than earlier estimates, and treatments have limited efficacy and are costly. Limited clinical and experimental evidence suggest that patients with autism may benefit from electroconvulsive therapy (ECT). We examined the therapeutic potential of ECT in BTBR T+ tf/j mice, which represent a validated model of autism. A series of 13 electroconvulsive shocks (ECS) delivered twice a day over 7 days reversed core autism-like behavioral abnormalities-impaired sociability, social novelty, and repetitive behavior-when the animals were tested 24 h after the last ECS. The effect lasted up to 2 weeks after ECT. Neither single ECS nor a series of 6 ECS modified animals' behavior. Chronic infusion into the lateral brain ventricle of a preferential oxytocin receptor blocker (2S)-2-Amino--(methylsulfonyl)butanamide hydrochloride abolished ECTinduced improvement of sociability and mitigated improvement of social novelty but did not affect ECT-induced reversal of repetitive behavior. These proof-of-principle experiments suggest that ECT may, indeed, be useful in the treatment of autism, and that its therapeutic effects may be mediated, in part, by central oxytocin signaling.
Neonatal seizures are common, occurring in 2 to 5 of 1,000 live births in the United States. The neonatal brain is thought to be predisposed toward seizures due to a combination of excessive excitatory and deficient inhibitory neuronal activity. The seizures tend to be focal or multifocal without secondary generalization, resulting in subtle seizure appearance. There are five main categories of neonatal seizures: focal clonic, focal tonic, myoclonic, subtle, and generalized tonic. An electroencephalogram is recommended to diagnose and treat neonatal seizures due to poor reliability of the clinical examination. Causes of neonatal seizures are broad, including trauma, structural brain anomalies, infections, metabolic disorders, drug withdrawal or intoxication, and neonatal epilepsy syndromes. Treatment of neonatal seizures involves management of cardiorespiratory status, correction of metabolic derangements, and antiepileptics as needed. The most common antiepileptics used in neonates are phenobarbital, levetiracetam, and fosphenytoin. The long-term risk of neurodevelopmental disability varies depending upon the etiology of neonatal seizures. Close attention to developmental milestones and neurology follow-up is recommended for all neonates with seizures. [ Pediatr Ann . 2020;49(7):e292–e298.]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
