Huntington's disease (HD) is a rare neurodegenerative disorder with a distinct phenotype, including involuntary movements, cognitive decline, and behavioral disturbances. Sleep disorder include insomnia, increased sleep onset latency, decrease in total sleep time with frequent nocturnal awakenings and excessive daytime sleepiness. Increased sleep motor activities and abnormal nocturnal agitation have been increasingly recognized as an important component affecting negatively the sleep quality.

Status epilepticus (SE) represents one of the most common neurological emergencies, associated with high mortality and an important risk of functional sequelae in survivors. Magnetic resonance imaging (MRI) offers the possibility of early and noninvasive observation of seizure-induced parenchymal disturbances secondary to the epileptic process. In the present review, we propose a descriptive and comprehensive understanding of current knowledge concerning seizure-induced MRI abnormalities in SE, also called peri-ictal MRI abnormalities (PMAs).

Kidney transplant recipients develop atypical infections in their epidemiology, presentation and outcome. Among these, meningitis and meningoencephalitis require urgent and adapted anti-infectious therapy, but published data is scarce in KTRs. The aim of this study was to describe their epidemiology, presentation and outcome, in order to improve their diagnostic and management.

Background And Objectives: Status epilepticus (SE) is a life-threatening emergency requiring a prompt assessment of patient prognosis to guide management. MRI allows the identification of peri-ictal MRI abnormalities (PMAs) and provides insight into brain structural modifications induced by SE. However, little is known about the significance of PMA in SE prognosis.

Objective: Germline loss-of-function mutations in DEPDC5, and in its binding partners (NPRL2/3) of the mammalian target of rapamycin (mTOR) repressor GATOR1 complex, cause focal epilepsies and increase the risk of sudden unexpected death in epilepsy (SUDEP). Here, we asked whether DEPDC5 haploinsufficiency predisposes to primary cardiac defects that could contribute to SUDEP and therefore impact the clinical management of patients at high risk of SUDEP.

Methods: Clinical cardiac investigations were performed in 16 patients with pathogenic variants in DEPDC5, NPRL2, or NPRL3.

Focal malformations of cortical development (MCD) are linked to somatic brain mutations occurring during neurodevelopment. Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is a newly recognized clinico-pathological entity associated with pediatric drug-resistant focal epilepsy, and amenable to neurosurgical treatment. MOGHE is histopathologically characterized by clusters of increased oligodendroglial cell densities, patchy zones of hypomyelination, and heterotopic neurons in the white matter.

Introduction: Papilledema is a common sign in ophthalmology and is typically associated with increased intracranial pressure (ICP) in neurological diseases. Since the beginning of the 20th century, some cases of papilledema have been reported in association with acute or chronic inflammatory neuropathies.

Case Report: We describe a 42-year-old man with acute-onset inflammatory polyradiculoneuropathy and bilateral papilledema.

Weston-Hurst syndrome is an exceptional variant of ADEM characterized by brain hemorrhages. Lesions are usually supratentorial and death is a usual outcome. We report a cerebellar Weston-Hurst syndrome early treated by craniectomy, steroids and plasma exchange.
