Patients with cerebellar lesions present some affective and cognitive disorders, defining a peculiar pattern of cognitive impairment, so-called cerebellar cognitive affective syndrome. This pattern has been confirmed in many genotypes of spinocerebellar ataxias (SCA), a group of genetically defined pathologies characterized by the degeneration of the(More)
We administered a large battery of neuropsychological tests to an heterogeneous cohort of genetically defined spinocerebellar ataxia (SCA) patients in order to assess their cognitive profile and to compare cognitive impairment among different SCA genotypes, particularly between SCA with the classical pattern of olivo-ponto-cerebellar atrophy (SCA1 and SCA2)(More)
Since the introduction of brain mapping, evidences of functional gender differences have been corroborating previous behavioral and neuropsychological results showing a sex-specific brain organization. We investigated gender differences in brain activation during the performance of the Tower of London (TOL) task which is a standardized test to assess(More)
IMPORTANCE Progressive supranuclear palsy (PSP) is usually sporadic, but few pedigrees with familial clustering of PSP-like phenotypes have been described. Occasionally, MAPT, C9ORF72, and TARDBP mutations have been identified. OBJECTIVE To analyze the DCTN1 gene in 19 families with a clinical phenotype of PSP (PSP-like phenotype). DESIGN, SETTING, AND(More)
IMPORTANCE Posterior cortical atrophy (PCA) is characterized by progressive visuoperceptual and visuospatial deficits and commonly considered to be an atypical variant of Alzheimer disease. Mutations of the GRN gene are responsible for a large phenotypic spectrum, but, to our knowledge, the association of PCA with GRN mutations has never been described. (More)
Spinocerebellar ataxias type 2 (SCA2) is a rare genetic disorder characterised by the degeneration of the Cerebellum, its connections and many Brainstem areas. A voxel-based morphometry (VBM) analysis was performed on 12 genetically determined SCA2 patients and 31 controls, normalising the brains with two different atlases: one was created in-house with(More)
Cerebellum seems to have a role both in feeding behavior and emotion regulation; therefore, it is a region that warrants further neuroimaging studies in eating disorders, severe conditions that determine a significant impairment in the physical and psychological domain. The aim of this study was to examine the cerebellum intrinsic connectivity during(More)
Recent studies focussing on neuroimaging features of eating disorders have observed that anorexia nervosa (AN) is characterized by significant grey matter (GM) atrophy in many brain regions, especially in the cerebellum and anterior cingulate cortex. To date, no studies have found GM atrophy in bulimia nervosa (BN) or have directly compared patients with AN(More)
IMPORTANCE Mutations in the progranulin (GRN) gene are responsible for 20% of familial cases of frontotemporal dementias. All cause haploinsufficiency of progranulin, a protein involved in inflammation, tissue repair, and cancer. Carriers of the GRN mutation are characterized by a variable degree of asymmetric brain atrophy, predominantly in the frontal,(More)
