Paternal exposure to antiseizure medications and offspring outcomes: a systematic review.
Concerns have recently been raised about risks to the fetus resulting from paternal exposure to antiseizure medications (ASMs). To address these concerns, we conducted a systematic review of the literature to assess neurodevelopmental and anatomical outcomes in offspring born to fathers taking ASMs at the time of conception. ⋯ Although there were limited data available, this systematic review provides reassuring evidence that paternal exposure to ASMs at conception is unlikely to pose any major risk of adverse outcomes for the offspring. Further research is needed to examine the relationship between preconception ASM use in males and offspring outcomes at birth and postnatally.

Sodium valproate is associated with cortical thinning of disease-specific areas in juvenile myoclonic epilepsy.
Juvenile myoclonic epilepsy (JME) is associated with cortical thinning of the motor areas. The relative contribution of antiseizure medication to cortical thickness is unknown. We aimed to investigate how valproate influences the cortical morphology of JME. ⋯ Valproate was associated with JME-specific and dose-dependent thinning of the cortical motor regions. This suggests that valproate is a key modulator of cortical morphology in JME, an effect that may underlie its high efficacy in this syndrome.

Visuospatial dysfunction predicts dementia-first phenoconversion in isolated REM sleep behaviour disorder.
While isolated rapid eye movement sleep behaviour disorder (iRBD) is known as a prodrome of α-synucleinopathies, the prediction for its future phenoconversion to parkinsonism-first or dementia-first subtype remains a challenge. This study aimed to investigate whether visuospatial dysfunction predicts dementia-first phenoconversion in iRBD. ⋯ Visuospatial dysfunction, as reflected mainly by the modified posterior subscore of MoCA, is a predictive factor for dementia-first phenoconversion in iRBD, suggesting its potential for being a biomarker for clinical prognostic prediction and potential neuroprotective trials aiming to delay or prevent dementia.

Object naming after epilepsy surgery in the dominant left temporal lobe: risk factors, time course and long-term outcome.
Deterioration in naming function is a common sequelae after epilepsy surgery in the language-dominant temporal lobe but information on recovery and long-term outcome is scarce. We, therefore, assessed short-term and long-term outcome of object naming in patients undergoing surgery in the temporal lobe and determined factors affecting deterioration and recovery of naming function. ⋯ In our cohort, less than 50% of PWE showed significantly deteriorated naming function after resection of the dominant temporal lobe. If a decline occurred, it appeared to recover to a certain degree and remained as a permanent deficit in 26% of the patients. Long-term outcome of visual object naming can be predicted by the degree of early postoperative decline.
