Neuropsychological testing of patients in the course of their recovery from brain injuries enables analysis of cognitive deficiencies and/or emotional changes. The principle study objective was to define organic and/or reactive personality changes and the course of these changes in the function of the time span following brain artery aneurysm surgery in both female and male patients. The study was carried out at the Clinical Department of Neurosurgery, Zagreb University Hospital Center in Zagreb. The data refer to the period from 1989 to 2012 collected in two time intervals, i...

BACKGROUND: The optimal treatment for low-grade gliomas remains controversial. Neurosurgery, radiotherapy, and chemotherapy are the main treatment options. Despite advances in oncology, there are still a lot of uncertainties, and the optimal sequences, combinations, and timings of these procedures have not yet been optimized. It is still unclear whether temozolomide can replace effective, but toxic PCV chemotherapy (procarbazine, lomustine, vincristine) and whether temozolomide can be used upfront alone instead of radiotherapy alone...

OBJECTIVE Cerebral mapping for surgical planning and operative guidance is a challenging task in neurosurgery. Pediatric patients are often poor candidates for many modern mapping techniques because of inability to cooperate due to their immature age, cognitive deficits, or other factors. Resting-state functional MRI (rs-fMRI) is uniquely suited to benefit pediatric patients because it is inherently noninvasive and does not require task performance or significant cooperation. Recent advances in the field have made mapping cerebral networks possible on an individual basis for use in clinical decision making...

BACKGROUND: Patient-reported preoperative factors hold promise in improving the prediction of postoperative adverse events, but they have been poorly studied. OBJECTIVE: To study the role of patient-reported factors in the preoperative risk stratification of elective craniotomy patients. METHODS: A prospective, unselected cohort of 322 adult patients underwent elective craniotomy in Helsinki, Finland. We preoperatively recorded the American Society of Anesthesiologists (ASA) score, Helsinki ASA score, and 3 questionnaire-based patient-reported factors including overall health status, ability to climb 2 flights of stairs, and cognitive function (Test Your Memory test)...

To determine the spatiotemporal relationships among intrinsic networks of the human brain, we recruited seven neurosurgical patients (four males and three females) who were implanted with intracranial depth electrodes. We first identified canonical resting-state networks at the individual subject level using an iterative matching procedure on each subject's resting-state fMRI data. We then introduced single electrical pulses to fMRI pre-identified nodes of the default network (DN), frontoparietal network (FPN), and salience network (SN) while recording evoked responses in other recording sites within the same networks...

OBJECTIVES: Subarachnoid haemorrhage (SAH) has high mortality and morbidity among survivors. SAH mainly affects young people and may result in long-term disabilities such as decreased Health-related Quality of Life (HRQoL), mental health and cognitive function. The aim of this study was to investigate the life situation 5 years after a SAH including physical/emotional status, participation and HRQoL. MATERIALS & METHODS: In this cross-sectional descriptive study, a mail survey was sent to all persons treated at a neurosurgery unit in Gothenburg, Sweden, for non-traumatic SAH in 2009-2010, approximately 5 years post-SAH...

Contrary to common psychosurgical practice in the 1950s, Dr. Jean Talairach had the intuition, based on clinical experience, that the brain connectome and neuroplasticity had a role to play in psychosurgery. Due to the remarkable progress of pharmacology at that time and to the technical limits of neurosurgery, these concepts were not put into practice. Currently, these concepts are being confirmed by modern techniques such as neuroimaging and computational neurosciences, and could pave the way for therapeutic innovation in psychiatry...

BACKGROUND: Acromegaly is caused by elevated secretion of human growth hormone, which is frequently because of intracranial tumors. This diagnosis is fairly uncommon with an incidence of 3 to 4 cases per million patients per year. We are presenting a case of acromegaly diagnosed in an active duty Chief Petty Officer. MATERIALS AND METHODS: A 38-year-old male Chief Petty Officer with no previous mental health diagnosis experienced post-traumatic stress disorder (PTSD)-like symptoms in early 2012 after deploying to Iraq and Afghanistan from 2010 to 2011...

This article describes the distinctive function of the pediatric clinical research nurse (CRN) in the anesthesia setting. The pediatric CRN in anesthesia acts as a liaison between families and the research team and is the major nexus between the principal investigator or anesthesiologist on a study, and the collaborating surgeons from many different departments. This is unique because the CRNs collaborate with physicians in specialties that can include plastics, urology, neurosurgery, orthopaedics, otolaryngology, cardiology, critical care, and many other departments...

INTRODUCTION: Treatment decisions in elderly patients with traumatic brain injury (TBI) are mainly determined by trauma severity and patient age. The aim of this study was to explore personal preferences of potential patients regarding life-prolonging neurosurgical interventions by interviewing ambulatory, autonomous elderly people. METHODS: One hundred consecutive patients older than 75 years frequenting the outpatient clinic of the Department of Neurosurgery were interviewed about their attitudes regarding the hypothetical case of an 81-year-old patient with TBI and a space-occupying acute subdural hematoma (aSDH) using a 21-point questionnaire...

INTRODUCTION: The indication for awake brain surgery depends on a prerequisite, i.e. recognition that the brain area concerned is truly eloquent, and identification of one or more functions that must be preserved. These functions are determined preoperatively in collaboration with the patient, and neuropsychological tests considered to be the most relevant are performed in the operating room according to each team's technical preferences. OPERATING ENVIRONMENT: The neurosurgeon must choose transfer equipment considered to be relevant...

Neuropsychological care of patients suffering from an infiltrative glioma and candidates for a neurosurgery under awake condition with intraoperative functional mapping is a critical and mandatory stage in therapeutic management. It enables to estimate the functional impact of the tumor and, consequently, the efficacy of functional reorganization typically observed in these patients, not only to better predict surgery outcomes and select appropriate tasks for intraoperative functional mapping, but also to plan efficient and individualized postoperative cognitive rehabilitation strategies...

Prolonged weaning of patients with neurological or neurosurgery disorders is associated with specific characteristics, which are taken into account by the German Society for Neurorehabilitation (DGNR) in its own guideline. The current S2k guideline of the German Society for Pneumology and Respiratory Medicine is referred to explicitly with regard to definitions (e.g., weaning and weaning failure), weaning categories, pathophysiology of weaning failure, and general weaning strategies. In early neurological and neurosurgery rehabilitation, patients with central of respiratory regulation disturbances (e...

This paper reviews the structural specificities and functional roles in Brodmann areas 10 and 38. A number of studies have focused on both areas through various approaches including neuropsychology, neuroimaging, psychiatry, neurology, and neurosurgery. Both areas 10 and 38 may have a substantially very complex higher-order cognitive functions, which are quite hard to disentangle. Here, I picked up some fundamental perspectives for reviewing previous studies, to provide efficient research orientations for the elucidation of functions in both areas...
