Abstract:

Refractory frontal lobe epilepsy has been traditionally treated through a frontal lobectomy. A disconnective technique may allow similar seizure outcomes while avoiding the complications associated with large brain resections. The aim of this study was to describe a new technique of selective disconnection of the frontal lobe that can be performed in cases of refractory epilepsy due to epileptogenic foci involving 1 frontal lobe (anterior to the motor cortex), with preservation of motor function. In addition to the description of the technique, an illustrative case is also presented.This disco

Abstract:

BackgroundAs a disconnection syndrome, schizophrenia has shown impaired resting-state functional connectivity (rsFC) in the orbitofrontal cortex (OFC); however, the OFC is a rather heterogeneous region and the rsFC changes in the OFC subregions remain unknown.MethodA total of 98 schizophrenia patients and 102 healthy controls underwent resting-state functional MRI using a sensitivity-encoded spiral-in imaging sequence (SENSE-SPIRAL) to reduce susceptibility-induced signal loss and distortion. The OFC subregions were defined according to a previous parcellation study that divided the OFC into t

Abstract:

Disconnection syndromes are often conceptualized exclusively within cognitive box-and-arrow diagrams unrelated to brain anatomy. In a patient with alexia in his left visual field resulting from a posterior callosal lesion, we illustrate how diffusion tensor imaging can reveal the anatomical bases of a disconnection syndrome by tracking the degeneration of neural pathways and relating it to impaired fMRI activations and behavior. Compared to controls, an abnormal pattern of brain activity was observed in the patient during word reading, with a lack of activation of the left visual word form are

Abstract:

Abstract Behavioural deficits in stroke reflect both structural damage at the site of injury, and widespread network dysfunction caused by structural, functional, and metabolic disconnection. Two recent methods allow for the estimation of structural and functional disconnection from clinical structural imaging. This is achieved by embedding a patient’s lesion into an atlas of functional and structural connections in healthy subjects, and deriving the ensemble of structural and functional connections that pass through the lesion, thus indirectly estimating its impact on the whole brain connecto

Abstract:

Abstract Hemispheric disconnection syndrome is a rarely reported sequela of aneurysm rupture. Serial neurobehavioral examinations of such a patient after clipping of a right pericallosal artery that had bled into a large portion of the corpus callosum disclosed defects in interhemispheric transfer of information and competitive movements between the left and right extremities. Although the patient's postoperative memory deficit subsequently resolved, his disconnection syndrome persisted and was primarily responsible for his disability despite otherwise normal neurological findings.

Abstract:

That disconnection causes clinical symptoms is a very influential concept in behavioral neurology. Criteria for subcortical disconnection usually are symptoms that are distinct from those following cortical lesions and damage to a single, long-range fiber tract. Yet, a recent study combining functional magnetic resonance imaging and fiber tracking concluded that a focal lesion in left parietal white matter provides the only tenable explanation for pure Gerstmann’s syndrome, an enigmatic tetrad of acalculia, agraphia, finger agnosia, and left-right disorientation.

Abstract:

Efforts to relate the syndrome of alexithymia to cerebral dysfunction have generally taken the form of comparing the literal, concretistic, nonimaginative and affect-impoverished cognitive and communicative style of alexithymic patients to similar types of behavior seen in individuals with right-hemisphere damage or commissural disconnection. It is argued that the formulation of a neuropsychological typology of psychiatric syndromes like alexithymia has much heuristic merit as long as appropriate theoretical and methodological caution is exercised in drawing inferences about patterns of cerebr

Abstract This paper uses first person inquiry and presentational form to argue the case for a sensory approach to understanding professional connection and disconnection with children who may be being abused. The approach is underpinned by an epistemology or theory of knowledge which stems from a participatory world-view where appearances are not permanent or separate from us: the act of perception takes place between the active sensible world and our own bodies, where ‘otherness’ expresses itself directly to our senses. Thus perception, conceived in this way, can lead to right action in the m

Awake surgery with cognitive monitoring has increasingly been implemented to preserve brain networks and functionality. More recently, not only surgery in the left but also in the right hemisphere, i.c., the parietal lobe, was associated with potential risk for deficits in cognitive functions, such as cognitive flexibility. In this explorative pilot study, we compare cognitive performance more than three months after surgery with baseline measurements and explore the association between cognitive decline and subcortical tracts that may have been severed during surgery in the right hemisphere.

Abstract:

✓ Residual seizures after functional hemispherectomy occur in approximately 20% of patients with catastrophic epilepsy. These episodes are traditionally attributed to incomplete disconnection, persistent epileptogenic activity in the ipsilateral insular cortex, or bilateral independent epileptogenic activity. The authors report on the case of an 8-year-old boy with an intractable seizure disorder who had classic frontal adversive seizures related to extensive unilateral left hemispheric cortical dysplasia. The initial intervention consisted of extensive removal of the epileptic frontal and pre

Abstract:

Abstract Hypothalamic hamartomas often cause refractory epilepsy, best controlled with surgery. A transcallosal interforniceal approach provides good outcomes although it has resulted in some complications including fornix lesions with transitory and permanent memory losses.1-2 Endoscopic disconnection is less invasive, avoids interhemispheric approach, callosotomy and fornix as well as propagation of epileptic discharges.3,4 Laser disconnection does not allow objective measurement of the vaporized tissue and can cause significant hypothalamic edema. We demonstrate a simple hypothalamic discon

Objective:To assess the contribution of microstructural normal-appearing white matter (NAWM) damage to social cognition impairment, specifically in the theory of mind (ToM), in multiple sclerosis (MS).Methods:We enrolled consecutively 60 patients with MS and 60 healthy controls (HC) matched on age, sex, and education level. All participants underwent ToM testing (Eyes Test, Videos Test) and 3T brain MRI including conventional and diffusion tensor imaging sequences. Tract-based spatial statistics (TBSS) were applied for whole-brain voxel-wise analysis of fractional anisotropy (FA) and mean diff

Abstract:

Intracranial dural arteriovenous fistulas (dAVF) with cervical perimedullary drainage, Cognard V, are a surgically challenging rare entity. In this video we show the disconnection of a right tentorial Cognard V dAVF, done through a subtemporal transtentorial approach with the application of indocyanine green video angiography. A 47-year-old man presented with severe tetraparesis. Only partial embolization was possible. An osteoplastic frontotemporal craniotomy was performed to obtain a wide view along with CSF release to safely mobilize the temporal lobe. Neuronavigation was used to detect the

Abstract:

SummaryLateral gaze aversions which follow reflective or thought provoking questions are called conjugated lateral eye movements (CLEMs). This response was studied in 20 schizophrenic patients, 20 depressive patients and 20 healthy controls. Frontal and parietal EEG measures were recorded simultaneously with the question/answer task. There were no differences in CLEMs among the 3 groups. Schizophrenic and depressive patients demonstrated a significantly reduced EEG-power on the left and an increased power on the right in comparison with healthy controls. This may point to a functional interhem

Abstract:

Limb pain as a presenting feature of an ischemic or hemorrhagic stroke is extremely rare. Here we present a case of a 65-year-old male with complaints of left arm pain and allodynia (specifically light touch to any part of the left arm produced significant discomfort) who was found to have a right parietal lobe intraparenchymal bleed after smoking crack cocaine. Acute central pain is mainly associated with parietal, thalamic, and brainstem lesions. It has been proposed that acute limb pain from a parietal lobe stroke is due to the disconnection of the parietal cortex from the thalamus secondar

Abstract:

Background: Brain disconnection plays a major role in determining cognitive disabilities in multiple sclerosis (MS). We recently developed a novel diffusion-weighted magnetic resonance imaging (DW-MRI) tractography approach, namely anatomical connectivitity mapping (ACM), that quantifies structural brain connectivity. Objective: Use of ACM to assess structural connectivity modifications in MS brains and ascertain their relationship with the patients’ Paced-Auditory-Serial-Addition-Test (PASAT) scores. Methods: Relapsing–remitting MS (RRMS) patients ( n = 25) and controls ( n = 25) underwent MR
