Summary: Infantile and epileptic spasms syndrome (IESS) is characterized by spasms, abnormal EEG, and epilepsy. The molecular and circuit-level causes of IESS are not well understood. This study found that inhibitory circuit dysfunction occurs in mice with deletions in adenomatous polyposis coli (APC), which may contribute to IESS-related phenotypes.

Summary: Neuroactive steroids are emerging as a new class of drugs for treating neuropsychiatric disorders, with effects on ligand-gated neurotransmitter receptors being a major mechanism of action. MQ-221, a sulfated, 3 beta-hydroxy neurosteroid analogue, inhibits NMDAR function while potentiating GABA(A)R function, showing potentially unique and clinically desirable effects. It may represent a new class of compound with unique psychoactive effects and beneficial prospects for treating neuropsychiatric disorders.

Summary: This report presents a case of a 5-month-old infant with epileptic spasms and developmental delay, who had non-isolated ventriculomegaly in utero and a right ventricular choroid plexus papilloma (CPP) as revealed by brain magnetic resonance imaging. Despite the use of antiepileptic therapies, the epileptic spasms persisted and were apparently cured after the removal of the CPP.

Summary: This study proposes a seizure prediction framework for infantile spasms by combining statistical analysis and deep learning model. The study analyzes the mechanism of epileptic changes by dividing continuous scalp electroencephalograms (sEEG) into 5 phases and constructing a brain network of 5 typical brain rhythms. The optimized model achieves high accuracy, specificity, and recall rate on data from 25 patients with infantile spasms.

Summary: The objective of this study was to analyze the clinical features, treatment, and prognosis of patients with vitamin B6-responsive infantile spasms. The results showed that high doses of vitamin B6 effectively controlled epileptic spasms in most patients, and had positive outcomes in terms of EEG, development and prognosis.

Summary: This study evaluated the efficacy and safety of ganaxolone in patients with CDKL5 deficiency disorder (CDD) and refractory epilepsy. The results showed that ganaxolone significantly reduced seizure frequency in CDD patients and was generally well tolerated. The study suggests a potential treatment benefit for ganaxolone in CDD and further long-term treatment is being assessed in the ongoing open-label extension phase.

Summary: This study aimed to investigate the correlation between pretreatment electroencephalography (EEG) measures (relative power spectrum, weighted phase lag index, and graph theoretical analysis) and outcomes following adrenocorticotropic hormone (ACTH) therapy in infants with non-lesional infantile epileptic spasms syndrome (IESS). The study found significant differences in power and functional connectivity between outcome groups, suggesting that these measures may contribute to early prediction of ACTH therapy outcomes and help guide treatment strategies.

Summary: This study characterized the etiology and natural history of infantile-onset focal epilepsy. Results showed a high incidence of infantile-onset focal epilepsy, often caused by known etiologies, and a high rate of drug-resistant epilepsy. However, infants without a known cause and with normal development tend to have a favorable course.

Summary: The study compared the effectiveness and safety of hormonal therapy and corticosteroids for infantile spasms. It found that oral corticosteroids can be used as alternative options when ACTH is not applicable, and ACTH is more beneficial for patients without tuberous sclerosis complex. Low-dose ACTH therapy is recommended due to its comparative effectiveness and lower risk of adverse effects. However, due to the high heterogeneity of patients and treatment protocols, these findings should be interpreted cautiously. Further research with larger sample sizes and multicentric involvement is needed to evaluate the effectiveness of other alternative treatments.

Summary: This study describes the patient characteristics and response to initial treatment of infantile epileptic spasms syndrome in a large case series in Bangladesh. The study emphasizes the importance of early referral of children with suspected epileptic spasms to epilepsy care centers in low- and middle-income countries.

Summary: ACTH is an effective treatment for infantile spasms, achieving complete cessation of spasms in the short term and positive outcomes in the long term. However, potential side effects such as dyskinesias should be further investigated in future studies. Additional randomized controlled clinical trials are needed to compare the effectiveness of ACTH in polytherapy and monotherapy.

Summary: This retrospective study evaluated the efficacy and tolerability of dexamethasone (DEX) for the treatment of infantile spasms (IS) and IS-related Lennox-Gastaut syndrome (LGS). The results showed that oral DEX has good efficacy and tolerability for the treatment of IS and IS-related LGS.
