Role of responsive neurostimulation and immunotherapy in refractory epilepsy due to autoimmune encephalitis: A case report.

Autoimmune encephalitis (AE) frequently presents with seizures in the acute setting. Seizures are often refractory to anti-seizure medications (ASM) but have been shown to be responsive to immunomodulatory therapies. A subset of patients with AE continues to have refractory epilepsy, recently named "autoimmune-associated epilepsy (AAE)," for years after the acute AE presentation.

Anti-NMDAR Encephalitis: A Multidisciplinary Approach to Identification of the Disorder and Management of Psychiatric Symptoms.

Background: The novelty of anti-NMDA receptor encephalitis, for which somatic treatments have only recently been developed, has led to a lack of information on assessment and treatment of its variable behavioral manifestations.

Method: In this article, we discuss 4 challenging cases of anti-NMDAR encephalitis, focusing on the importance of a multidisciplinary approach to identification and management of the disorder and the necessity of close collaboration in the acute hospital setting for management of the behavioral symptoms.

Conclusion: The cases we discuss highlight some of the medication and nonpharmacologic treatment strategies that may facilitate management of psychiatric symptoms, both while the medical workup is ongoing and after the diagnosis has been confirmed.

Sex Differences and the Impact of Chronic Stress and Recovery on Instrumental Learning.

We have previously shown that 21-day chronic restraint stress impacts instrumental learning, but overall few studies have examined sex differences on the impact of stress on learning. We further examined sex differences in response to extended 42-day chronic stress on instrumental learning, as well as recovery from chronic stress. Rats were tested in aversive training tasks with or without prior appetitive experience, and daily body weight data was collected as an index of stress.
