Management of severe (drug-resistant) epilepsy and epilepsy in other serious illnesses is multidimensional and requires consideration of both physical symptoms and psychosocial distress that require individualized treatment. Palliative care offers a holistic approach to disease that focuses on all dimensions of suffering to maintain quality of life. Integration of a palliative care mind- and skillset in the management of severe epilepsy and epilepsy in other serious illnesses can provide person-centered care and support for families and caregivers.

Idiopathic intracranial hypertension (IIH) has its highest prevalence among women of childbearing age and therefore frequently coincides with pregnancy. This retrospective cohort study aimed to explore the impact of pregnancy on the clinical course, ophthalmologic findings and on the therapeutic management of IIH patients. Individual patient records were reviewed for neuro-ophthalmologic findings, treatment strategy, adherence to therapy and pregnancy complications.

Palliative care adds significant burdens to healthcare workers. In neuropalliative care (NPC), additional challenges include patient symptom burdens, such as impairments in mobility, cognition, and communication. After one year of operating the first NPC ward in Germany, we assessed burdens, resources, and the number of deaths perceived as stressful.

Background: When treating patients with epileptic seizures in the emergency room (ER), it is of paramount importance to rapidly assess whether the seizure was acute symptomatic or unprovoked as the former points to a potentially life-threatening underlying condition. In this study, we seek to identify predictors and analyze characteristics of acute symptomatic seizures (ASS).

Methods: Data from patients presenting with seizures to highly frequented ERs of two sites of a university hospital were analyzed retrospectively.

Acute and unexpected hospitalization can cause serious distress, particularly in patients with palliative care needs. Nevertheless, the majority of neurological inpatients receiving palliative care are admitted an emergency department. Identification of potentially avoidable causes leading to acute hospitalization of patients with neurological disorders or neurological symptoms requiring palliative care.

Objective: In focal epilepsy, data on the etiology-specific response to antiseizure medication (ASM) are surprisingly sparse. In this study, we sought to reappraise whether seizure outcome of pharmacological treatment is linked to the underlying etiology. Furthermore, we assessed ASM load with respect to the cause of epilepsy.

Objectives: In genetic generalized epilepsies (GGE), valproic acid (VPA) is the most efficacious compound. However, due to teratogenicity and increased risk for impaired cognitive development after intrauterine exposure, its use in women of fertile age is strictly regulated but sometimes unavoidable.

Methods: All patients with GGE treated at the outpatient clinic of a tertiary epilepsy center with at least one visit between January 2015 and April 2020 were included in this retrospective study.

Background: Electroencephalography (EEG) significantly contributes to the neuroprognostication after resuscitation from cardiac arrest. Recent studies suggest that the prognostic value of EEG is highest for continuous recording within the first days after cardiac arrest. Early continuous EEG, however, is not available in all hospitals.

Objective: To determine whether serum creatine kinase activity (CK) and serum creatinine concentration (Crn) are prognostic and predictive biomarkers for disease severity, disease progression, and nusinersen treatment effects in adult patients with 5q-associated spinal muscular atrophy (SMA).

Methods: Within this retrospective, multicenter observational study in 206 adult patients with SMA, we determined clinical subtypes (SMA types, ambulatory ability) and repeatedly measured CK and Crn and examined disease severity scores (Hammersmith Functional Motor Scale Expanded, Revised Upper Limb Module, and revised Amyotrophic Lateral Sclerosis Functional Rating Scale). Patients were followed under nusinersen treatment for 18 months.

Objectives: To identify demographic and clinical variables independently associated with patients' decisions against their physicians' recommendations for resective epilepsy surgery or further scalp video-EEG monitoring (sca-VEM), semi-invasive (sem-)VEM with foramen ovale and/or peg electrodes, and invasive (in-)VEM.

Methods: Consecutive patients, who underwent presurgical assessment with at least one sca-VEM between 2010 and 2014, were included into this retrospective analysis. Multivariate analysis was used to identify independent variables associated with patients' decisions.

Iatrogenic nerve injuries are rare complications of total hip and knee arthroplasty, which may cause chronic pain and loss of function, severely affecting the patient's daily activities and quality of life. Nerves "at risk" include the sciatic nerve, the femoral nerve, the lateral femoral cutaneous nerve and the superior gluteal nerve during total hip arthroplasty, and the infrapatellar branch of the saphenous nerve as well as the peroneal nerve during total knee arthroplasty. Multiple procedure-related and patient-related factors have been identified to modify the risk of nerve injury in the course of lower limb joint replacement surgery.

Objective: Leucine-rich glioma-inactivated 1 (LGI1) encephalitis is the second most common antibody-mediated encephalopathy, but insight into the intrathecal B-cell autoimmune response, including clonal relationships, isotype distribution, frequency, and pathogenic effects of single LGI1 antibodies, has remained limited.

Methods: We cloned, expressed, and tested antibodies from 90 antibody-secreting cells (ASCs) and B cells from the cerebrospinal fluid (CSF) of several patients with LGI1 encephalitis.

Results: Eighty-four percent of the ASCs and 21% of the memory B cells encoded LGI1-reactive antibodies, whereas reactivities to other brain epitopes were rare.

Objective: Despite the obvious advantages of resective surgery in patients with drug-resistant focal epilepsy, namely high probability of seizure freedom, decreased mortality, and increased quality of life, referral rates from physicians and approval rates by patients for presurgical assessment remain constantly low.

Methods: In the outpatient clinics of a tertiary epilepsy center, checklists were implemented asking treating epileptologists whether they recommended presurgical evaluation with noninvasive video-electroencephalographic monitoring to adult patients with drug-resistant focal epilepsy and asking respective patients whether they followed this recommendation.

Results: Of 185 eligible patients, 80 (43%) were recommended presurgical evaluation by their epileptologists, and 24 (30%) of these patients consented.

Objectives: Depending on patient age at onset, absence epilepsy is subdivided into childhood and juvenile forms. Absence seizures can occur several times per day (pyknoleptic course) or less frequently than daily (non-pyknoleptic course). Seizures typically terminate before adulthood, but a quarter of patients need ongoing treatment beyond adolescence.

Objective: Until now, it has been unclear if the three subsyndromes of adolescent-onset generalized genetic epilepsy (GGE) differ in long-term prognosis. Therefore, this study aimed to compare long-term seizure outcome in juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and epilepsy with generalized tonic-clonic seizures alone (EGTCS).

Methods: This retrospective study is based on the archive of an institutional tertiary care outpatient clinic for adult patients with epilepsy.

Background: In patients taking antiepileptic drugs (AEDs) for epilepsy, adverse effects (AEs) often lead to unfavorable quality of life, impaired adherence, and, eventually, discontinuation of pharmacological treatment. In a true-to-life sample of subjects from our academic epilepsy outpatient clinic, we aimed to identify predictors for overall high AE burden and for specific AEs focusing on patients on monotherapy.

Methods: All patients ≥16years of age with epilepsy for ≥12months were routinely asked to complete the Liverpool Adverse Event Profile (LAEP) just before their appointment.

Functional magnetic resonance imaging (fMRI), cyclic voltammetry, and single-unit electrophysiology studies suggest that signals measured in the nucleus accumbens (Nacc) during value-based decision making represent reward prediction errors (RPEs), the difference between actual and predicted rewards. Here, we studied the precise temporal and spectral pattern of reward-related signals in the human Nacc. We recorded local field potentials (LFPs) from the Nacc of six epilepsy patients during an economic decision-making task.

Neuromodulative treatment options are warranted in patients with difficult-to-treat epilepsy. However, acquisition of controlled data on deep brain stimulation has so far been achieved only for the centromedian and anterior thalamic nucleus. In a case series of four patients with intractable partial epilepsy, a randomized controlled cross-over protocol was used to get insight into efficacy and safety of 3-month nucleus accumbens stimulation.

In epilepsy, novel pharmacological and nonpharmacological treatment approaches are commonly assessed in model systems of acute motor and often generalized seizures. We developed a rodent model with short-term electrical stimulation of the perforant path resulting in stereotyped limbic seizures. Limbic structures play a major role in human intractable epilepsy.
