Objective: Critical treatment and management have advanced over the recent decades, bringing many benefits but also causing increasing complication rates. Among these complications, neurological complications have an important place and may increase in mortality rates. The aim of our study was to find the causes of neurological consultations in the level 3 adult intensive care units (ICU).
Methods: The study population consisted of patients who were requested to have neurology consultation in the level 3 Adult ICUs between April 2013 and April 2017. The records in the hospital automation system of patients required neurology consultation were evaluated retrospectively.
Results: A total of 906 neurology consultations were requested in ICUs and 302 patients were included in this study. Altered consciousness and unconsciousness (32.1%), seizure (26.5%), management and treatment (15.9%) were the most common reasons for neurological consultations. Epileptic seizures (16.9%), status epilepticus (9.3%) and ischemic stroke (8.6%) were the most common final neurological diagnoses after consultation. Wernicke encephalopathy, posterior reversible encephalopathy syndrome, motor neuron disease, Creutzfeldt-Jakob disease, critical illness polyneuropathy and critical illness myopathy were less frequently diagnosed (< 1%). The diagnostic benefit was 83.1%. Treatment change following neurological consultation occurred in 56.6% of the patients.
Conclusions: In our study, spanning a period of 4 years, the most common diagnoses were epileptic seizure, status epilepticus, and ischemic stroke. More frequent complications, such as stroke and seizure, as well as less common complications such as Wernicke's encephalopathy and posterior reversible encephalopathy syndrome, should be intervened immediately. In case of consultation, neurologists should be able to manage neurological complications as a consultant physician in the early period and evaluate the ICU patient systematically and be familiar with the complexity of intubation, sedation and sometimes paralyzed intensive ICU patients who have had severely limited routine clinical evaluations.

Rationale And Objectives: To evaluate and compare image quality of different energy levels of virtual monochromatic images (VMIs) using standard versus strong deep learning spectral reconstruction (DLSR) on dual-energy CT pulmonary angiogram (DECT-PA).
Materials And Methods: A retrospective study was performed on 70 patients who underwent DECT-PA (15 PE present; 55 PE absent) scans. VMIs were reconstructed at different energy levels ranging from 35 to 200 keV using standard and strong levels with deep learning spectral reconstruction.

The subspecialty of neurocritical care has grown significantly over the past 40 years along with advancements in the medical and surgical management of neurological emergencies. The modern neuroscience intensive care unit (neuro-ICU) is grounded in close collaboration between neurointensivists and neurosurgeons in the management of patients with such conditions as ischemic stroke, aneurysmal subarachnoid hemorrhage, intracerebral hemorrhage, subdural hematomas, and traumatic brain injury. Neuro-ICUs are also capable of specialized monitoring such as serial neurological examinations by trained neuro-ICU nurses; invasive monitoring of intracranial pressure, cerebral oxygenation, and cerebral hemodynamics; cerebral microdialysis; and noninvasive monitoring, including the use of pupillometry, ultrasound monitoring of optic nerve sheath diameters, transcranial Doppler ultrasonography, near-infrared spectroscopy, and continuous electroencephalography.

Deep brain stimulation (DBS), a proven treatment for movement disorders, also holds promise for the treatment of psychiatric and cognitive conditions. However, for DBS to be clinically effective, it may require DBS technology that can alter or trigger stimulation in response to changes in biomarkers sensed from the patient's brain. A growing body of evidence suggests that such adaptive DBS is feasible, it might achieve clinical effects that are not possible with standard continuous DBS and that some of the best biomarkers are signals from the cerebral cortex.

Introduction: Down Syndrome Regression Disorder (DSRD) is a neuropsychiatric condition causing insomnia, catatonia, encephalopathy, and obsessive-compulsive behavior in otherwise healthy individuals with Down syndrome (DS). Smaller cohorts have identified heterogenous diagnostic abnormalities which have predicted immunotherapy responsiveness although pattern analysis in a large cohort has never been performed.
Methods: A multi-center, retrospective study of individuals with DSRD was performed.

Background: Recurrent attacks in neuromyelitis optica spectrum disorders (NMOSDs) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can lead to severe disability. We aimed to analyse the real-world use of immunotherapies in patients with NMOSD and MOGAD, focusing on changes in treatment strategies, effects on attack rates (ARR) and risk factors for attacks.
Methods: This longitudinal registry-based cohort study included 493 patients (320 with aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive NMOSD (65%), 44 with AQP4-IgG seronegative NMOSD (9%) and 129 MOGAD (26%)) with 1247 treatments from 19 German and one Austrian centre from the registry of the neuromyelitis optica study group (NEMOS).
