A new test of action verb naming: normative data from 290 italian adults

Introduction Verbs and nouns can be selectively impaired, suggesting that they are processed, at least in part, by distinct neural structures. While several tests of object naming are available, tasks involving action verb naming with normative data are lacking. We report the construction and standardization of a new test for the assessment of picture naming of actions. Material and methods The test includes 50 stimuli, strictly controlled for several confounding variables. Normative data on 290 Italian subjects pooled across homogenous subgroups for age, sex, and education are reported. Results Multiple regression analyses revealed that age and education significantly correlated with the subject\u2019s score. In particular, increasing age negatively affected performance, while the performance increased with a higher education. Conclusions In the clinical practice, the availability of equivalent scores will help the comparison with performance in the picture naming of objects. This test allows investigating action naming deficits in aphasic patients, in Parkinson\u2019s disease patients and in further neurodegenerative disorders, in which a specific impairment of action verbs is expected, filling a gap in the clinical neuropsychological assessment

Patient-reported outcome measures in patients with familial cerebral cavernous malformations: results from the Treat_CCM trial

BackgroundThe Phase 1/2 Treat_CCM randomized controlled trial for people with familial cerebral cavernous malformations (FCCMs) confirmed the safety of propranolol and suggested beneficial effects on intracerebral hemorrhage or new focal neurological deficits, but the effects on patient-reported outcome measures have not been reported.MethodsParticipants completed self-reported questionnaires at baseline, 1 and 2 years. Depression was assessed with the Beck Depression Inventory-II (BDI-2); Anxiety with the State–Trait Anxiety Inventory X1 and X2 (STAI X-1 and STAI X-2); and Quality of Life with the Short Form 36 (SF-36), split into the physical and mental component scales (PCS and MCS). Differences between treatment groups and the general population were assessed. Change over time by treatment was assessed by means of mixed models.ResultsIn total, 71 participants (48 propranolol and 23 standard care) were enrolled, of whom 61 (73%) completed questionnaires at baseline and 2-year FU. At baseline, no differences between treatment groups for any of the questionnaires were present. Twenty (31.7%) patients were considered depressed at baseline, while this proportion was lower in the propranolol group after 2 years (28.6% vs. 55.5%, p = 0.047). The STAI X-1 and X-2 scores were stable over time. PCS was lower in FCCM patients as compared with the general Italian population, while the MCS was similar to the general population. No effect of propranolol was found for both PCS and MCS.ConclusionDepression is common among patients with FCCM. Patients randomized to propranolol had a lower proportion of participants with depression after 2 years.Clinical trial registration: https://clinicaltrials.gov/, identifier (NCT03589014)

Surgery in elderly patients with intracranial meningioma : neuropsychological functioning during a long term follow-up

Surgical treatment of elderly patients with meningioma is has proved to be safe, especially when patients are selected using dedicated surgical scores. These scores take into account tumor size, edema, location and patient's co-morbidities. Neuropsychological functioning (NPF) of this kind of patients has been poorly studied in literature and it is not taken into account by these scores. Aim of our study was to describe the long-term outcome in terms of NPF of elderly patients undergoing surgery. Patients older than 70\ua0years of age affected by intracranial meningioma and selected with the Clinical-Radiological Grading Score were included in our study. Neuropsychological testing was performed using a dedicated battery of tests before surgery, 3 and 12\ua0months after surgery. Clinical, neurological and radiological outcomes were studied as well. Forty-one patients with a median age of 74\ua0years were included in this study. Preoperatively only 1/41 patients showed a normal NPF with all tests scoring normally. Four out of 39 patients showed a complete neuropsychological recovery after 3 months; while 10/37 patients had a complete recovery after 12\ua0months. NPF showed a trend of progressive improvement after surgery. Our study is the first experience reported in literature describing a long term follow-up in elderly patients after surgery for intracranial meningioma. In our series, surgery determined an improvement of NPF over time; especially with a low complication rate related to the selection of patients obtained through the CRGS. Further studies need to be performed in order to understand how brain edema, tumor size, volume and tumor location affect NPF in both short and long term

Insular lobe surgery and cognitive impairment in gliomas operated with intraoperative neurophysiological monitoring

Background: For a long time, surgery of insular gliomas was considered at high risk for postoperative cognitive deficits, but recent studies highlighted the feasibility of the surgical approach. The aims of our study were to investigate the presence of language impairment before and after surgery and the relationship between language impairment and tumor volume preoperatively and extent of resection (EOR) 3 months after surgery. Methods: Thirty-five patients with insular gliomas underwent an extensive language assessment before and few days after surgery, and after 3 months. Intraoperative neurophysiological monitoring (IOM) and brain mapping with direct electrical stimulation (DES) were used in all the cases; 8 patients underwent awake craniotomy. Statistical analysis was performed on the language tests administered. Results: Patients with pure left insular lesion showed language impairment before and after surgery. Overall, patients with a left lesion showed a drop of performance after surgery followed by a partial recovery. Moreover, when the tumor involved the insula and adjacent networks, we observed a more severe deficit. No correlations were found between tumor volume, EOR, and language impairment. Conclusions: Left insular lobe is an important hub in language networks; its involvement determines pre- and postsurgical deficits, together with the involvement of white matter connections. Tumor volume and EOR are not risk factors per se directly related to language functioning. Surgery of insular gliomas is possible with a pre- and intraoperative extensive study of the patient with IOM and awake surgery, and encouraged by the trend of cognitive recovery highlighted

Role of Intraoperative Neurophysiologic Monitoring in the Resection of Thalamic Astrocytomas

BACKGROUND: The thalamus is a deep-seated and crucial structure for the sensorimotor system. It has been long considered a surgically inaccessible area because of the morbidity associated with surgical resections. Astrocytomas of the thalamus are usually treated with bioptic procedures followed by adjuvant treatments. Intraoperative neurophysiologic monitoring (IONM) allows safe and satisfactory resections of lobar gliomas, but few data are available for thalamic lesions. The aim of this study was to review the outcome of a small series of patients with thalamic astrocytomas that were treated with surgical resection with the aid of IONM. METHODS: Surgical resection with IONM was performed in 5 patients with thalamic astrocytomas (1 grade I, 1 grade II, 2 grade III, 1 grade IV). Two astrocytomas were in the dominant hemisphere. Preoperative and postoperative neuropsychological assessments were performed in 3 patients. IONM was tailored to the individual patient and consisted of transcranial motor evoked potential monitoring, cortical motor evoked potential monitoring, somatosensory evoked potential monitoring, direct electrical stimulation, electroencephalography, and electrocorticography. RESULTS: None of the patients experienced permanent motor deficits; 2 patients had a transient hemiparesis requiring rehabilitation; 1 patient had a transient aphasia, and 1 patient had permanent aphasia. None of the patients had intraoperative seizures, but 1 patient experienced postoperative transient status epilepticus. The extent of resection on postoperative volumetric magnetic resonance imaging was >70% in all cases. CONCLUSIONS: Surgical resection of thalamic astrocytomas appeared to be effective and relatively safe when guided by IONM. Larger series of patients are required to confirm these preliminary data

Personalized and translational approach for malignant brain tumors in the era of precision medicine: the strategic contribution of an experienced neurosurgery laboratory in a modern neurosurgery and neuro-oncology department

Personalized medicine (PM) aims to optimize patient management, taking into account the individual traits of each patient. The main purpose of PM is to obtain the best response, improving health care and lowering costs. Extending traditional approaches, PM introduces novel patient-specific paradigms from diagnosis to treatment, with greater precision. In neuro-oncology, the concept of PM is well established. Indeed, every neurosurgical intervention for brain tumors has always been highly personalized. In recent years, PM has been introduced in neuro-oncology also to design and prescribe specific therapies for the patient and the patient's tumor. The huge advances in basic and translational research in the fields of genetics, molecular and cellular biology, transcriptomics, proteomics, and metabolomics have led to the introduction of PM into clinical practice. The identification of a patient's individual variation map may allow to design selected therapeutic protocols that ensure successful outcomes and minimize harmful side effects. Thus, clinicians can switch from the \u201cone-size-fits-all\u201d approach to PM, ensuring better patient care and high safety margin. Here, we review emerging trends and the current literature about the development of PM in neuro-oncology, considering the positive impact of innovative advanced researches conducted by a neurosurgical laboratory
