Visual vertical neglect in acquired brain injury: a systematic review.

Vertical neglect represents a visuospatial deficit occurring as a possible consequence of acquired brain injury (ABI). Differently from unilateral spatial neglect on horizontal space, vertical neglect is poorly studied in the literature and rarely assessed in clinical practice. In the available studies, the terms "radial," "vertical," and "altitudinal" neglect are often used interchangeably, although they do not describe the same spatial dimension.

Family caregivers improve the diagnostic accuracy of disorders of consciousness: from remote to near-bed auditory stimulation.

Background: Family caregivers (FC) contribute to reducing the misdiagnosis rate in patients with disorders of consciousness (DOC). Unfortunately, the recent pandemic of COVID-19 imposed drastic restrictions that limited the access of FC to the sensory/cognitive stimulation protocols. Telemedicine approaches have been implemented to avoid discontinuity in care pathways and to ensure caregivers involvement in rehabilitation programs.

Free Thyroxine (fT4) as a Potential Biomarker of Neurological and Functional Outcome in Acquired Brain Injury: A Prospective Multicenter Cohort Study.

The potential involvement of thyroid hormones (THs) in the neurological and functional recovery of patients with brain damage has been hypothesized. We aimed at investigating the role of THs and their variations during the rehabilitation process as predictive biomarkers of neurological and functional outcome in patients with acquired brain injury (ABI). This prospective, multicenter cohort study included 220 patients with ABI consecutively admitted for a 6-month neurorehabilitation program.

Cognitive impairment is associated with gait variability and fall risk in amyotrophic lateral sclerosis.

Background: In amyotrophic lateral sclerosis (ALS), gait abnormalities contribute to poor mobility and represent a relevant risk for falls. To date, gait studies in ALS patients have focused on the motor dimension of the disease, underestimating the cognitive aspects.

Methods: Using a wearable gait analysis device, we compared gait patterns in ambulatory ALS patients with mild cognitive impairment (ALS MCI+; n = 18), and without MCI (ALS MCI-; n = 24), and healthy subjects (HS; n = 16) under two conditions: (1) normal gait (single task) and (2) walking while counting backward (dual task).

Cognitive Impairment in Convalescent COVID-19 Patients Undergoing Multidisciplinary Rehabilitation: The Association with the Clinical and Functional Status.

Background: Cognitive impairment has been reported in the aftermath of severe acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) infection. We investigated the possible association between cognitive impairment and the main clinical and functional status variables in a cohort of convalescent COVID-19 patients without premorbid diseases potentially affecting cognition.

Methods: We consecutively screened for inclusion of convalescent COVID-19 patients referring to a post-acute care facility for pulmonary rehabilitation.

Prognosis of severe acquired brain injury: Short and long-term outcome determinants and their potential clinical relevance after rehabilitation. A comprehensive approach to analyze cohort studies.

Background: Accurate prognostic evaluation is a key factor in the clinical management of patients affected by severe acute brain injury (ABI) and helps planning focused therapies, better caregiver's support and allocation of resources. Aim of the study was to assess factors independently associated with both the short and long-term outcomes after rehabilitation in patients affected by ABI in the setting of a single Rehabilitation Unit specifically allocated to these patients.

Methods And Findings: In all patients (567) with age ≥ 18 years discharged from the Unit in the period 2006/2015 demographic, etiologic, comorbidity indicators, and descriptors of the disability burden (at hospital admission and discharge) were evaluated as potential prognostic factors of both short-term (4 classes of disability status at discharge) and long-term (mortality) outcomes.

Prospective memory is dysfunctional in migraine without aura.

Introduction Prospective memory is the ability to carry out a delayed intended action, so to maintain and retrieve future plans, goals and activities. Deficits of prospective memory negatively impact on patients and caregivers' everyday living and determine poor adherence to treatment. Since frontal regions are involved in both event- and time-based prospective memory tasks and are impaired in migraine without aura, defects of prospective memory might occur in migraine without aura patients; until now this issue has not been investigated.

Migraine Does Not Affect Pain Intensity Perception: A Cross-Sectional Study.

Objective: To explore perceived pain intensity (PPI) in three drug-naïve patient groups characterized by homogeneous migraine phenotypes-migraine without aura without cutaneous allodynia (MwoA CA-), MwoA with ictal CA (MwoA CA+), and migraine with aura without cutaneous allodynia (MwA CA-)-compared with age- and sex-matched healthy controls (HCs).

Methods: Using trigeminal heat stimulation (THS) at three different predefined intensities (41 °C, 51 °C, and 53 °C) performed by the contact heat-evoked potential stimulator (CHEPS), PPI was investigated in 34 patients with MwoA CA-, 30 patients with MwoA CA+, and 30 patients with MwA CA- compared with 30 age- and sex-matched HCs. The patients had never taken migraine-preventive drugs, and they were investigated during an interictal period to avoid confounds associated with migraine attack.

Functional Changes of the Perigenual Part of the Anterior Cingulate Cortex after External Trigeminal Neurostimulation in Migraine Patients.

Objective: To explore the functional reorganization of the pain processing network during trigeminal heat stimulation (THS) after 60 days of external trigeminal neurostimulation (eTNS) in migraine without aura (MwoA) patients between attacks.

Methods: Using whole-brain BOLD-fMRI, functional response to THS at two different intensities (41 and 51°C) was investigated interictally in 16 adults MwoA patients before and after eTNS with the Cefaly device. We calculated the percentage of patients having at least a 50% reduction of monthly migraine attacks and migraine days between baseline and the last month of eTNS.

Cognitive dysfunctions and psychological symptoms in migraine without aura: a cross-sectional study.

Background: The occurrence of cognitive dysfunctions and psychological symptoms, as well as their mutual relationships, in migraine patients are still debated. The aim of the study was to characterize the cognitive profile and psychological symptoms (i.e.

Functional interictal changes of pain processing in migraine with ictal cutaneous allodynia.

Objective A prospective clinical imaging study has been conducted to investigate pain processing functional pathways during trigeminal heat stimulation (THS) in patients with migraine without aura experiencing ictal cutaneous allodynia (CA) (MwoA CA+). Methods Using whole-brain BOLD-fMRI, functional response to THS at three different intensities (41°, 51° and 53℃) was investigated interictally in 20 adult MwoA CA+ patients compared with 20 MwoA patients without ictal CA (MwoA CA-) and 20 healthy controls (HCs). Secondary analyses evaluated associations between BOLD signal change and clinical features of migraine.

Transcutaneous supraorbital neurostimulation in "de novo" patients with migraine without aura: the first Italian experience.

Background: Transcutaneous supraorbital neurostimulation (tSNS) has been recently found superior to sham stimulation for episodic migraine prevention in a randomized trial. We evaluated both the safety and efficacy of a brief period of tSNS in a group of patients with migraine without aura (MwoA).

Methods: We enrolled 24 consecutive patients with MwoA experiencing a low frequency of attacks, which had never taken migraine preventive drugs in the course of their life.

Vestibular migraine pathophysiology: insights from structural and functional neuroimaging.

Vestibular migraine (VM) has been increasingly recognized as a frequent cause of episodic vertigo, affecting up to 1 % of the general population, with female preponderance. Recently, both the Bárány Society and the Migraine Classification Subcommittee of the International Headache Society have proposed original diagnostic criteria for VM, which have been included in the recent edition of the ICHD-3 beta version. VM diagnosis implies that vestibular symptoms are present during a migraine attack, with or without headache, in the absence of objectively demonstrated interictal vestibulopathy.

Abnormal thalamic function in patients with vestibular migraine.

Objective: To investigate the functional response of neural pathways associated with vestibular stimulation in patients with vestibular migraine (VM).

Methods: Twelve patients with VM underwent whole-brain blood oxygen level-dependent (BOLD) fMRI during ear irrigation with cold water. The functional response of neural pathways to this stimulation in patients with VM was compared with age- and sex-matched patients with migraine without aura and healthy controls.

Executive resting-state network connectivity in migraine without aura.

Background: Converging neuropsychological evidence suggests that in migraine executive functions (EF) may be affected during interictal periods.

Objective: To evaluate the functional connectivity of the fronto-parietal networks (FPN) known to be associated with EF, in migraine without aura (MwoA) patients, in the interictal period, in comparison to healthy controls (HC).

Methods: Using resting-state functional MRI (RS-fMRI), we compared functional connectivity within the FPN in 14 patients with MwoA versus 14 sex- and age-matched HC, and assessed the correlation between functional connectivity within FPN, clinical features of MwoA patients, and EF.

Resting-state brain connectivity in patients with Parkinson's disease and freezing of gait.

Background: Freezing of gait is a common cause of disability and falls in patients with Parkinson's disease. We studied brain functional connectivity, by means of resting-state functional magnetic resonance imaging, in patients with Parkinson's disease and freezing of gait.

Methods: Resting-state functional magnetic resonance imaging at 3 T was collected in 29 patients with Parkinson's disease, of whom 16 presented with freezing of gait as determined by a validated freezing of gait questionnaire, and 15 matched healthy controls.
