Clara Haskil (January 7, 1895-December 7, 1960) was one of the most famous female pianists of the 20th century. In her life and work she set new standards in piano playing. However, her career was beset by poor health and the adversities of two world wars. In her lifetime Haskil had three major disorders: juvenile scoliosis requiring treatment in her adolescence, a tumor of the sellar region requiring surgery at age 47 years, and a traumatic brain injury causing her death at the age of 65. Her medical history illustrates the development of surgical methods and rehabilitation in medicine before and after World War II...

OBJECTIVE: To investigate the effects of topiramate (TPM), zonisamide (ZNS), and levetiracetam (LEV) on cognitive network activations in patients with focal epilepsy using an fMRI language task. METHODS: In a retrospective, cross-sectional study, we identified patients from our clinical database of verbal fluency fMRI studies who were treated with either TPM (n = 32) or ZNS (n = 51). We matched 62 patients for clinical measures who took LEV but not TPM or ZNS. We entered antiepileptic comedications as nuisance variables and compared out-of-scanner psychometric measures for verbal fluency and working memory between groups...

OBJECTIVE: To investigate whether genetics, underlying pathology or repeated seizures contribute to atrophy in specific white matter tracts. METHODS: Medically-refractory unilateral temporal lobe epilepsy with hippocampal sclerosis (HS-TLE, n=26) was studied as an archetype of focal epilepsy, using fixel-based analysis of diffusion-weighted imaging. A genetic effect was assessed in first-degree relatives of HS-TLE who did not have epilepsy themselves (HS-1°Rel; n=26)...

Cristina Diana Ghinda, Hugues Duffau
Gliomas are the most frequent primary brain tumors and include a variety of different histological tumor types and malignancy grades. Recent achievements in terms of molecular and imaging fields have created an unprecedented opportunity to perform a comprehensive interdisciplinary assessment of the glioma pathophysiology, with direct implications in terms of the medical and surgical treatment strategies available for patients. The current paradigm shift considers glioma management in a comprehensive perspective that takes into account the intricate connectivity of the cerebral networks...

OBJECTIVES: This study examined whether individuals with Parkinson's disease (PD) are at increased vulnerability for vascular-related cognitive impairment relative to controls. The underlying assumption behind this hypothesis relates to brain reserve and that both PD and vascular risk factors impair similar fronto-executive cognitive systems. METHODS: The sample included 67 PD patients and 61 older controls (total N=128). Participants completed neuropsychological measures of executive functioning, processing speed, verbal delayed recall/memory, language, and auditory attention...

Resective neurosurgery carries the risk of postoperative cognitive deterioration. The concept of 'hub (over)load', caused by (over)use of the most important brain regions, has been theoretically postulated in relation to symptomatology and neurological disease course, but lacks experimental confirmation. We investigated functional hub load and postsurgical cognitive deterioration in patients undergoing lesion resection. Patients (n = 28) underwent resting-state magnetoencephalography and neuropsychological assessments preoperatively and 1-year after lesion resection...

We aimed to identify reorganization processes of episodic memory networks in patients with left and right temporal lobe epilepsy (TLE) due to hippocampal sclerosis as well as their relations to neuropsychological memory performance. We investigated 28 healthy subjects, 12 patients with left TLE (LTLE) and 9 patients with right TLE (RTLE) with hippocampal sclerosis by means of functional magnetic resonance imaging (fMRI) using a face-name association task, which combines verbal and non-verbal memory functions...

#12
Chris Tailby, David F Abbott, Graeme D Jackson
"Which is the dominant hemisphere?" is a question that arises frequently in patients considered for neurosurgery. The concept of the dominant hemisphere implies uniformity of language lateralisation throughout the brain. It is increasingly recognised that this is not the case in the healthy control brain, and it is especially not so in neurological diseases such as epilepsy. In the present work we adapt our published objective lateralisation method (based on the construction of laterality curves) for use with sub-lobar cortical, subcortical and cerebellar regions of interest (ROIs)...

OBJECTIVE: Glioma survival correlated with the extent of resection and the functional status of the patient. We detailed functional results along with oncological results after a functional-based resection of gliomas located within eloquent regions. MATERIAL AND METHODS: Single centre prospective series of adult patients with gliomas located within eloquent regions, treated with maximal resection according to functional boundaries using intraoperative cortico-subcortical monitoring under awake conditions, with available functional outcomes (language and cognitive assessments, neurological status, ability to work) and oncological outcomes (extent of surgical resection, survivals)...

OBJECTIVE: Voxel-based lesion-symptom mapping (VLSM) was used to localize impairments specific to multiword (phrase and sentence) spoken language comprehension. METHODS: Participants were 51 right-handed patients with chronic left hemisphere stroke. They performed an auditory description naming (ADN) task requiring comprehension of a verbal description, an auditory sentence comprehension (ASC) task, and a picture naming (PN) task. Lesions were mapped using high-resolution MRI...

The speech disturbance resulting from infarction limited to the Broca area has been delineated; it differs from the speech disorder called Broca aphasia, which results from damage extending far outside the Broca area. Nor does Broca area infarction cause Broca aphasia. The lesions in 20 cases observed since 1972 were documented by autopsy, computerized tomography, or arteriogram; the autopsy records from the Massachusetts General hospital for the past 20 years and the published cases since 1820 were also reviewed...

PURPOSE: Anterior temporal lobe resection (ATLR) controls seizures in up to 70% of patients with intractable temporal lobe epilepsy (TLE) but, in the language dominant hemisphere, may impair language function, particularly naming. Functional reorganization can occur within the ipsilateral and contralateral hemispheres. We investigated reorganization of language in left-hemisphere-dominant patients before and after ATLR; whether preoperative functional magnetic resonance imaging (fMRI) predicts postoperative naming decline; and efficiency of postoperative language networks...

Naming difficulties are a well recognised, but difficult to predict, complication of anterior temporal lobe resection (ATLR) for refractory epilepsy. We used MR tractography preoperatively to demonstrate the structural connectivity of language areas in patients undergoing dominant hemisphere ATLR. Greater lateralisation of tracts to the dominant hemisphere was associated with greater decline in naming function. We suggest that this method has the potential to predict language deficits in patients undergoing ATLR...

Previous studies, using surveys, provided an understanding about how health-care providers address patients with PNES. To date, there is limited information on the management of patients with PNES by tertiary referral centers for epilepsy. In this study, we surveyed 11 Brazilian epilepsy center directors about diagnosis, treatment, education and research on PNES. Respondents reported that patients with PNES represented 10-20% of all adult patients recorded by video-EEG (VEEG). All respondents recognized VEEG as the method to confirm the diagnosis, and 81...

INTRODUCTION: Diagnosis threat has been shown to produce detrimental effects on neuropsychological performance in individuals with mild traumatic brain injury (mTBI). Focusing on contact-sport players who are at great risk of mTBI, our study was designed to examine the moderating role of internal locus of control. Specifically, we predicted that following diagnosis threat (reminder of their risk of sustaining mTBI and of its consequences), low-internal contact-sport players would underperform (assimilation to the stereotype), while their high-internal counterparts would outperform (contrast effect)...

OBJECTIVE Cerebral damage in frontal, parietal, and temporal brain areas and, probably more importantly, their interconnections can lead to deficits in language. However, neural plasticity and repair allow the brain to partly compensate for neural injury, mediated by both functional and structural changes. In this study, the authors sought to systematically investigate the relationship between language performance in brain tumor patients and structural perisylvian pathways (i.e., the arcuate fasciculus [AF]) using probabilistic fiber tracking on diffusion tensor imaging...
