No full textAutosomal Dominant Alzheimer's Disease with Early Frontal Lobe Involvement Associated with the Met239Ile Mutation of Presenilin 2 Gene.
No full textAbstract. Mutations in the Presenilin 2 gene (PSEN2) represent the less frequent genetic cause of familial Alzheimer’s disease (FAD). Only eight PSEN2 mutations, reported in approximately 27 families, satisfied strict criteria of pathogenicity.We reported a patient with early-onset FAD and the PSEN2 p.Met239Ile mutation, presenting with severe executive dysfunction and myoclonic tremor, associated with memory loss. Brain SPECT study showed an early hypoperfusion of the frontal cortex. We confirmed
the pathogenicity of PSEN2 p.Met239Ile mutation and its heterogeneous phenotypic expression. The modulating effect of the Apolipoprotein E and Prion Protein gene polymorphisms on the phenotypic variability was not confirmed
Catatonia as Presenting Manifestation of Behavioral Frontotemporal Dementia: Insight From a PET/MRI Study
No full textSimple motor stereotypies are not specific features of behavioural frontotemporal dementia
No full textγ-Hydroxybutyric acid-induced psychosis and seizures.
No full textDisulfiram and γ-hydroxybutyric acid (GHB) are used to treat alcohol dependence and may both increase dopamine brain levels and modulate GABAergic transmission. We describe a patient affected by bipolar disorder (on valproate as mood-stabilizing treatment) and alcohol dependence who developed a disulfiram-induced hypomanic episode and in whom the switch from disulfiram to GHB induced recurrent convulsive seizures, not responsive to treatment with diazepam, and psychosis. Seizures and psychiatric symptoms ceased after GHB discontinuation. We outline the deregulation of the neurotransmitter systems (GABAergic and dopaminergic networks) that are involved in these drug-drug interactions and that might be responsible for both psychosis and generalized tonic-clonic seizures resistant to standard treatments

No full textDiffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
