Pituitary T1 signal intensity at magnetic resonance imaging is reduced in patients with obesity: results from the CHIASM study.

BACKGROUND: Despite obesity being well known to be associated with several pituitary hormone imbalances, pituitary appearance in magnetic resonance imaging (MRI) in patients with obesity is understudied. OBJECTIVE: To evaluate the pituitary volume and signal intensity at MRI in patients with obesity. METHODS: This is a prospective study performed in an endocrine Italian referral center (ClinicalTrial.gov Identifier: NCT03458533). Sixty-nine patients with obesity (BMI > 30 kg/m2) and twenty-five subjects without obesity were enrolled. Thirty-three patients with obesity were re-evaluated after 3 years of diet and lifestyle changes, of whom 17 (51.5%) achieved a > 5% loss of their initial body weight, whereas the remaining 16 (48.5%) had maintained or gained weight. Evaluations included metabolic and hormone assessments, DEXA scan, and pituitary MRI. Pituitary signal intensity was quantified by measuring the pixel density using ImageJ software. RESULTS: At baseline, no difference in pituitary volume was observed between the obese and non-obese cohorts. At the 3-year follow-up, pituitary volume was significantly reduced (p = 0.011) only in participants with stable-increased body weight. Furthermore, a significant difference was noted in the mean pituitary intensity of T1-weighted plain and contrast-enhanced sequences between the obese and non-obese cohorts at baseline (p = 0.006; p = 0.002), and a significant decrease in signal intensity was observed in the subgroup of participants who had not lost weight (p = 0.012; p = 0.017). Insulin-like growth factor-1 levels, following correction for BMI, were correlated with pituitary volume (p = 0.001) and intensity (p = 0.049), whereas morning cortisol levels were correlated with pituitary intensity (p = 0.007). The T1-weighted pituitary intensity was negatively correlated with truncal fat (p = 0.006) and fibrinogen (p = 0.018). CONCLUSIONS: The CHIASM study describes a quantitative reduction in pituitary intensity in T1-weighted sequences in patients with obesity. These alterations could be explained by changes in the pituitary stromal tissue, correlated with low-grade inflammation.

A transient magnetic resonance spectroscopy peri-ischemic peak: a possible radiological biomarker of post-stroke neurogenesis.

BACKGROUND AND AIMS: In adult human brain, neurogenesis seems to persist throughout life and ischemic stroke was proved to stimulate this process. Using magnetic resonance spectroscopy (MRS), a 1.28-ppm peak, putative biomarker of neural progenitor cells (NPCs), was identified both in vitro and in vivo, i.e., in normal rat and healthy human brain. The aim of our study was to identify a 1.28-ppm peak in adult human ischemic brain by using 3.0 T multivoxel MRS. METHODS: We studied 10 patients, six males, and four females, with a mean (± SD) age of 59.3 (± 17.3), at three different time points from ischemic stroke onset (T0: < 5 days; T14: 14 ± 2 days; T30: 30 ± 2 days). RESULTS: In all patients except one, a 1.28-ppm peak at T14 was detected at the ischemic boundary (all p values < 0.05). MRS performed on six voluntary age-matched healthy subjects did not detect any 1.28-ppm peak. CONCLUSIONS: The nature of this 1.28-pm peak is uncertain; however, our data support the hypothesis that it might represent a marker of NPCs in post-stroke human brain.

A case of bilateral humerus varus from the late antiquity Catacomb of Santa Mustiola (Chiusi, Italy).

OBJECTIVE: To report a case of bilateral humerus varus from a late antiquity archeological context in central Italy. MATERIALS: The individual is a 25-40-year-old female, dated to the 4th cent. CE, from the catacomb of Santa Mustiola in Chiusi, Italy. METHODS: The bones were examined macroscopically and through CT scan imaging. RESULTS: Both humeri show evident alterations in shape, including elongated, flattened and distally dislocated humeral heads, shortened anatomical necks, angulated upper diaphyseal shafts, and reduced overall lengths. The scapulae appear to have been mildly affected by this condition and show some bone loss and slight retroversion of the glenoid cavity. CONCLUSIONS: Observations are consistent with a diagnosis of humerus varus deformity likely caused by a traumatic event early in the individual's life. SIGNIFICANCE: Varus deformity of the proximal humerus is seldom reported in bioarcheological literature. The case presented provides insight into the etiology and effects of this condition and may serve as comparison for future studies. LIMITATIONS: Even though the absence of other skeletal deformities renders a systemic condition improbable, the traumatic etiology of the condition cannot be confirmed with certainty. SUGGESTIONS FOR FURTHER RESEARCH: Future publications of new cases may give a broader perspective of the etiology of this condition in the past.

Metastatic cancer and endentulism: Exploring comorbidity to assist with differential diagnosis in a case from Vico nel Lazio (Fr, Italy), 13th-15th century CE.

OBJECTIVE: To differentially diagnose cranial lesions noted on a medieval skeleton and explore the importance of comorbidity. MATERIALS: A skull of an adult female with osteolytic and osteoblastic lesions, edentulism, and an ectopic tooth from an ossuary of the Church of Santa Maria in Vico del Lazio, Frosinone Italy, dating to the Middle Ages. METHODS: Macroscopic observations of the remains, CT scan, and differential diagnosis was undertaken. RESULTS: A diagnosis of metastatic cancer (potentially breast cancer) or metastatic neuroblastoma (NBL) is offered. CONCLUSIONS: Considering the noted comorbidities, this case might represent a rare case of metastatic neuroblastoma. SIGNIFICANCE: The exploration of comorbidity, in this case the presence of metastatic carcinoma and edentulism, has tremendous potential to expand our knowledge about cancer in the past. LIMITATIONS: Lack of postcranial elements. SUGGESTIONS FOR FURTHER RESEARCH: Clinical and paleopathological investigation of comorbidity in modern and archeological populations to develop an evolutionary perspective on the presence of cancer in the past.

Bevacizumab-containing regimen in relapsed/progressed brain tumors: a single-institution experience.

AIM: The aim of the study is to assess tumor response, treatment-related toxicities, progression-free survival (PFS), and overall survival (OS) in patients with relapsed/refractory brain tumors treated with bevacizumab-containing regimen. METHODS: Patients that had received I and II line treatments with or without megatherapy were included. Doses and schedule were as follows: bevacizumab (BVZ) 10 mg/kg i.v. with irinotecan (IRI) 150 mg/m2 i.v. every 2 weeks ± temozolamide (TMZ) 200 mg/m2 p.o. daily for 5 days every 4 weeks. TMZ was omitted in heavily pretreated cases. RESULTS: Between 2013 and 2018, 12 patients (3F/9M), median age 161 months (range 66-348), affected with medulloblastoma (n 7), or low-grade glioma (n 2), or high-grade glioma (n 3), received BVZ/IRI association (median courses 20, range 4-67); 3 of them continued single-agent BVZ (median courses 23, range 8-39). TMZ (median courses 8, range 2-26) was administered in eight patients and then stopped in three of them because of myelotoxicity or lack of compliance. Treatment was well tolerated. After 3 months, two complete responses, two partial responses, seven stable diseases, and one progressive disease were observed. Nine cases experienced an improvement in neurological symptoms. Median time to progression was 11 months (95% confidence interval, 4-18 months). Six-month and 2-year PFS were 75% and 42%, respectively. The OS is 33%; interestingly, two cases (one medulloblastoma and one high-grade glioma) are progression-free off-therapy since 30 and 48 months, respectively. CONCLUSIONS: BVZ/IRI association ± TMZ showed encouraging therapeutic activity and low toxicity in this series of relapsed/refractory brain tumors.

Peri-procedural brain lesions prevention in CAS (3PCAS): Randomized trial comparing CGuard™ stent vs. Wallstent™.

BACKGROUND: Aim of this study was to evaluate peri-procedural incidence of new diffusion-weighted-magnetic-resonance-imaging (DWMRI) brain lesions in CAS patients treated by carotid mesh stent (CGuard™) or closed-cell stent (Wallstent™). METHODS: Consecutive patients with asymptomatic carotid stenosis ≥ 70% were submitted to preoperative DW-MRI scan, to exclude the presence of preoperative silent cerebral lesions. Patients were randomized to CGuard or Wallstent. DWMRI was performed immediately after the intervention and at 72-hour postoperatively. Moreover, pre and postoperative Mini-Mental-State-Examination Test (MMSE) and a Montreal-Cognitive-Assessment (MoCA) test were conducted, and S100ß and NSE neurobiomarkers were measured at 5-time points (preoperatively, 2, 12, 24, and 48 h postoperatively). RESULTS: From January 2015 to October 2016, sixty-one consecutive eligible patients were submitted to preoperative DWMRI scan. Three patients were excluded because of preoperative silent cerebral lesions. In 29 CGuard patients, 1 developed a minor stroke and 8 silent new lesions were observed in the 72 h-DWMRI (31%): 4 lesions were ipsilateral, and 4 lesions were contra or bilateral. In 29 Wallstent patients, 7 clinically-silent new lesions were found in the 72 h-DWMRI (24.1%; p = 0.38). In 4 cases lesions were ipsilateral and in 3 cases contra or bilateral. S100B values doubled at 48 h in 24 patients, and among them 12 presented new DWMRI lesions. 48-h S100B increase was significantly related to 72-h DWMRI lesions (p = 0.012). CONCLUSIONS: In our experience both stents showed an acceptable rate of subclinical neurological events with no significant differences at 72-hour DWMRI between groups. Bilateral/contralateral lesions suggest that periprocedural neurological damage may have extra-carotid sources.

Immunological diagnosis as an adjunctive tool for an early diagnosis of tuberculous meningitis of an immune competent child in a low tuberculosis endemic country: a case report.

BACKGROUND: Pediatric tuberculous meningitis is a highly morbid, often fatal disease. Its prompt diagnosis and treatment saves lives, in fact delays in the initiation of therapy have been associated with high mortality rates. CASE PRESENTATION: This is a case of an Italian child who was diagnosed with tuberculous meningitis after a history of a month of headache, fatigue and weight loss. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis with predominance and decreased glucose concentration. Microscopy and conventional diagnostic tests to identify Mycobacterium tuberculosis were negative, while a non classical method based on intracellular cytokine flow cytometry response of CD4 cells in cerebral spinal fluid helped us to address the diagnosis, that was subsequently confirmed by a nested polymerase chain reaction amplifying a 123 base pair fragment of the M. tuberculosis DNA. CONCLUSIONS: We diagnosed tuberculous meningitis at an early stage through an innovative immunological approach, supported by a nested polymerase chain reaction for detection of M. tuberculosis DNA. An early diagnosis is required in order to promptly initiate a therapy and to increase the patient's survival.

In normal aging ventricular system never attains pathological values of Evans' index.

Ventricular enlargement in normal aging frequently forces the radiological diagnosis of hydrocephalus, but the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement (values > 0.30) during aging is not assessed. Here we analyze ventricular size during aging and the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement. We calculated Evans' index in the axial Computed Tomography scans of 1221 consecutive individuals (aged 45-101 years) from an emergency department. Stratified analysis of one-year cohorts showed that the mean Evans' index value per class was invariably < 0.30. Roughly one out five Computed Tomography scans was associated with Evans' index values > 0.30 and Evans' index values increased with age. The risk of having an Evans' index value > 0.30 increased by 7.8% per year of age (p < 0.001) and males were at 83.9% greater risk than females (p < 0.001). Overall, this study shows that normal aging enlarges the ventricular system, but never causes abnormal ventricular enlargement. Evans' index values > 0.30 should reflect an underlying neurological condition in every individual.

Olfactory Dysfunction, Olfactory Bulb Volume and Alzheimer's Disease: Is There a Correlation? A Pilot Study1.

BACKGROUND: Olfactory dysfunction is present since the earliest stage of Alzheimer's disease (AD). In AD patients, the olfactory impairment has been correlated with atrophy of some structures of the olfactory system, but the role of the olfactory bulb remains unclear. OBJECTIVE: The aim of our work is to test if patients suffering from AD exhibit a statistically significant reduction of the average volume of the olfactory bulb (OBV) compared to healthy subjects. METHODS: 78 subjects were enrolled in the study and divided into three groups: 28 healthy elderly (22 females, 6 males, mean age 69.4 ± 9.2), 25 patients with mild cognitive impairment (MCI) amnestic type (14 females, 11 males, mean age 74.5 ± 7.5), and 25 mild AD patients (14 females, 11 males, mean age 73.7 ± 6.8). Every subject underwent an MRI study of the olfactory bulb and an olfactory assessment with the Sniffin' Stick Extended Test. RESULTS: The statistical analysis showed no correlation between the OBV and MCI or AD. Moreover, olfactory function and OBV were not correlated in any of the three groups. CONCLUSION: The reduction of OBV does not seem to represent an index of neuronal damage in the earliest stages of AD.

The outcome of white matter abnormalities in early treated phenylketonuric patients: A retrospective longitudinal long-term study.

BACKGROUND: Pathogenesis and clinical consequences of white matter abnormalities on magnetic resonance imaging (MRI) in phenylketonuric (PKU) patients are incompletely known. OBJECTIVE: To study white matter alterations progression and outcome and its relationships with phenylalanine levels and intelligence quotient (IQ) in early treated PKU subjects who underwent serial MRIs during a prolonged follow-up. METHODS: 47 early treated PKU patients (mean age 25.1 ± 5.6 years; range 12-37 years) have been enrolled when two or more consecutive brain MRIs, a complete biochemical history, and MRI-concurrent blood phenylalanine levels were available. The severity and extension of white matter abnormalities were expressed in a computed score. Consecutive IQ assessments were available in 24 patients. We analyzed intra- and interindividual white matter alterations variations and their relationship with quality of biochemical control and cognitive outcome. RESULTS: Early treated PKU patients showed a high rate of white matter alterations with a relevant increase in frequency/severity from the second decade of life onwards. Age and quality of dietary control before or between subsequent examinations showed an independent cumulative effect on white matter alterations outcome. No significant association was found between white matter alterations and cognitive outcome. A remarkable interindividual variability was found and several patients disclosed incongruity between the trajectory of white matter alterations and biochemical control. About 30% of white matter alterations variability remains unexplained by the disease-associated determinants. CONCLUSIONS: The evolution of white matter alterations is not significantly affected by intellectual outcome and is affected by aging, chronic exposure to phenylalanine, and unknown individual factors.

Olfactory deficit and hippocampal volume loss for early diagnosis of Alzheimer disease: a pilot study.

BACKGROUND: The aim of this pilot study was to verify the role of olfactory test and volumetric magnetic resonance imaging measure of hippocampus to predict conversion from mild cognitive impairment to Alzheimer disease (AD). MATERIALS AND METHODS: Eighteen patients with amnesic mild cognitive impairment, broadly defined, were followed at 12 months. Hypothesized baseline predictors for follow-up conversion to AD were olfactory deficit and hippocampal volumes loss. RESULTS: In the 1-year follow-up, 5 patients converted to AD. The 2 clinical predictors olfactory test and hippocampal volume loss showed the same sensitivity of 92.3% but the olfactory test showed a higher specificity than the hippocampal volume loss (75% vs. 60%). CONCLUSIONS: Our findings suggest the potential utility of olfactory test and hippocampal volume loss for early detection of AD.

3T diffusion tensor imaging and electroneurography of peripheral nerve: a morphofunctional analysis in carpal tunnel syndrome.

OBJECTIVE: The aim of the study was to assess the diagnostic potential of diffusion tensor imaging (DTI) for pathologies of the peripheral nervous system (PNS) through clinical, electrophysiological and morphological evaluation of the median nerve. METHODS: The present work was a multilevel prospective study involving 30 subjects, 15 of whom had carpal tunnel syndrome (CTS) and 15 healthy controls. All subjects underwent clinical evaluation through administration of the Boston Carpal Tunnel Questionnaire (BCTQ), electroneurography (ENG), 3-Tesla magnetic resonance imaging with DTI, and calculation of fractional anisotropy (FA) and the apparent diffusion coefficient (ADC) at the flexor retinaculum. Tractography was also performed for three-dimensional reconstruction of the route of the median nerve through the carpal tunnel. The degree of functional impairment was compared with the anatomical damage to the median nerve according to ENG and DTI. RESULTS: FA and ADC were significantly correlated with ENG parameters of CTS and BCTQ data. Mean FA and ADC values in the CTS patients were 0.359±0.06 and 1.866±0.050×10(-3)mm(2)/s, respectively, vs 0.59±0.014 and 1.395±0.035×10(-3)mm(2)/s, respectively, in the controls. FA was decreased and ADC increased in patients with CTS compared with healthy controls (P<0.05). CONCLUSION: DTI parameters were clearly confirmed by both clinical and ENG data and, therefore, may be used for the diagnosis of CTS.

Evaluation of the basal ganglia in neurofibromatosis type 1.

PURPOSE: Alterations of the brain microstructure and metabolism have been identified in patients with neurofibromatosis type 1 (NF1). In this study, we analyzed the basal ganglia of NF1 subjects without cognitive delay throughout a combined approach with magnetic resonance spectroscopy (MRS) and diffusion tensor imaging (DTI) in order to better define the metabolic and microstructural characteristics of these regions and, furthermore, to verify if metabolic and microstructural abnormalities may be present in normally developed NF1 patients. METHODS: A 3-T MRI with multivoxel MRS and DTI was performed in 14 NF1 patients and eight controls. N-acetyl-aspartate (NAA), choline (Cho), creatine (Cr) values and ratios, fractional anisotropy, and apparent diffusion coefficient (ADC) were calculated, for a total of four regions of interest (ROI) for each hemisphere. RESULTS: NF1 patients, compared to healthy controls, showed (a) decreased NAA in all the four ROI, (b) increased Cho and decreased Cr in three of the four ROI, (c) decreased NAA/Cho ratio in three ROI, and (d) increased ADC in all the four ROI. A trend of increased ADC was present in three of the four ROI of NF1 patients with unidentified bright objects (UBOs) and younger than 18 years. CONCLUSION: These data confirm the presence of neuroaxonal damage with myelin disturbances in NF1 patients. We showed that metabolic and microstructural anomalies can be present in the same time in NF1 patients without developmental delay or cognitive deficits. Relations between brain anomalies, UBOs, and cognitive functions need further studies.

Rhinocerebral zygomycosis with pansinusitis in a 14-year-old girl with type 1 diabetes: a case report and review of the literature.

BACKGROUND: Zygomycosis is a rare life-threatening fungal infection affecting mostly patients with predisposing conditions such as diabetes mellitus, immunodeficiency, haemochromatosis or major trauma. METHODS: We describe a case of rhinocerebral zygomycosis in a girl with type 1 diabetes and review previous published cases and treatment options. RESULTS: A 14-year-old girl with type 1 diabetes mellitus occurred with dental pain, facial swelling, ecchymosis and left eye decreased visual acuity, unresponsive to antibiotic therapy. The cultures of the sinusal mucosa were positive for fungal species belonging to the Zygomycetes. She performed antifungal therapy with posaconazole (POS) with a very slow improvement and a poor glycemic control, leading to blindness of the left eye. CONCLUSION: Our report adds further awareness on rhinocerebral zygomycosis and emphasizes on urgent diagnosis and timely management of this potentially fatal fungal infection through an adequate treatment.

Corpus callosum abnormalities and potential age effect in men with schizophrenia: an MRI comparative study.

The goal of this investigation was to evaluate corpus callosum (CC) morphometry in schizophrenia. In consideration of possible confounders such as age, gender and handedness, our study sample was restricted to right-handed male subjects, aged 18-55 years. In addition, we controlled for age at onset, illness duration and exposure to antipsychotic medication. Midsagittal CC linear and area Magnetic Resonance Imaging (MRI) measurements were performed on 50 subjects with schizophrenia and 50 healthy controls. After controlling for midsagittal cortical brain area and age, Analysis of Covariance (ANCOVA) revealed an overall effect of diagnosis on CC splenium width and CC anterior midbody area and a diagnosis by age interaction. Independent Student t tests revealed a smaller CC splenium width in the 36- to 45-year-old age group among the patients with schizophrenia and a smaller CC anterior midbody area in the 18- to 25-year-old age group among the patients with schizophrenia compared with controls. Age, age at onset, illness duration and psychopathology ratings did not show any significant correlations with the whole CC MRI measurements. A negative correlation was found between CC rostrum area and the estimated lifetime neuroleptic consumption. The results are discussed in terms of the possibility that CC structural changes may underlie the functional impairments, frequently reported in schizophrenia, of the associated cortical regions.

Usefulness of diffusion tensor imaging and fiber tractography in neurological and neurosurgical pediatric diseases.

INTRODUCTION: Diffusion tensor imaging (DTI) with fiber tractography (FT) is a recently introduced imaging technique that is unique in providing detailed imaging of white matter (WM) tracts and connectivity between different regions of the brain not easily appreciated with other imaging methods. DISCUSSION: DTI has been used in recent years to investigate several disease conditions involving WM, including brain malformations, cerebral ischemia, multiple sclerosis, neurocutaneous syndromes, and brain tumors. CONCLUSION: In this paper, we focus our attention on the main applications of DTI-FT in the field of pediatric neurology, adding our personal experience.

Long-term posaconazole treatment and follow-up of rhino-orbital-cerebral mucormycosis in a diabetic girl.

To demonstrate that the 2-yr clinical follow-up of our patient strongly suggests that long-term therapy with posaconazole (POS) is safe and beneficial in treatment and prevention of relapses of, otherwise fatal, central nervous system mucormycosis. Mucormycosis is a very rare opportunistic mycotic infection of diabetic children. We present the 30-month follow-up of a 12-yr-old girl affected by diabetic ketoacidotic coma, complicated by rhinocerebral mucormycosis and successfully treated with POS at the initial daily dose of 5 mg/kg t.i.d. with fatty food for 3 wk, followed by a daily dose of 10 mg/kg in four doses for 2 months and then 20 mg/kg/d in four doses for 16 months and in two doses for further 5 months. The previous amphotericin B, granulocyte colony-stimulating factor, hyperbaric oxygen and nasal and left maxillary sinus surgical debridement therapy was ineffective in stopping the progression of the infection to the brain. The patient improved within 10 d with reduced ocular swelling and pain, and 6 months after therapy stop, she is in good health and cultures are sterile. This article demonstrates that POS may be a useful drug in mucormycosis in children. We also strongly draw the attention to the main preventive procedure against invasive fungal infection that is the correct management of antidiabetic therapy that prevents the predisposing temporary neutrophils activity deficit, contributing to a better survival rate of diabetic children.

Midline medulloblastoma versus astrocytoma: the position of the superior medullary velum as a sign for diagnosis.

PURPOSE: We wish to describe the position of the superior medullary velum (SMV) in midline posterior fossa tumours as a sign in helping to distinguish between midline medulloblastoma and midline astrocytoma. MATERIAL AND METHODS: Sagittal T1-weighted MRI images of 21 consecutive patients with histologically documented posterior fossa midline astrocytomas (nine cases) and medulloblastomas (12 cases) were reviewed, with respect to the position of the velum medullare superius. RESULTS: In all medulloblastomas the SMV was superiorly dislocated; in eight astrocytomas it was anteriorly and/or inferiorly disclocated; only in one astrocytoma the SMV presented upward dislocation. CONCLUSION: In the differential diagnosis between medulloblastoma and astrocytoma the upward dislocation of the SMV is strongly suggestive of medulloblastoma.

Neurological soft signs and cerebral measurements investigated by means of MRI in schizophrenic patients.

Neurophysiologic research has shown a Neurological Soft Sign (NSS) characteristic prevalence in schizophrenic patients, and correlations between NSS and the most frequently cerebral alterations. The aim of this study was to investigate, by means of MRI, the quantitative alterations of cortical and subcortical structures and their correlation with NSS in a sample of schizophrenic patients. Linear measures of lateral ventricular (Evans ratio), third ventricular (Third Ventricular Width), hippocampal (Interuncal Index) and cerebellar (Verm Cerebellar Atrophy) atrophy were made on magnified MR images of 33 patients with a DSM IV diagnoses of chronic schizophrenia. NSS were evaluated with the Buchanan and Heinrichs's Neurological Evaluation Scale (NES). Lateral ventricular enlargement showed to be correlated with right stereoagnosia item (p=0.001). Hippocampal atrophy, with right stereoagnosia item (p=0.023), with forefinger-right thumb opposition (p=0.004), forefinger-left thumb opposition (p=0.029 and face-hand extinction (0.26). Third ventricle enlargement showed to be correlated with forefinger-right thumb opposition (p=0.001), forefinger-left thumb opposition(p=0.021) and total sensorial integration (p=0.012). Cerebellar atrophy showed to be correlated with rhythmic drumming item (p=0.042), forefinger-right thumb opposition (p=0.007), forefinger-left thumb opposition (p=0.026), left specular movements (p=0.049), face-hand extinction (p=0.001), right-left confusion (p=0.005) and with left forefinger-nose index (p=0.032). Results obtained confirm the correlation between NSS and neuroanatomical alterations in schizophrenia.
