Visuo-spatial and imagery disorders
No full textThe domain of neuroscience has had one of the most explosive growths in recent decades: within this development there has been a remarkable and renewed interest in the study of the relations between behaviour and the central nervous system. Part of this new attention is connected with the contribution of new technologies (PET, fMRI) permitting more precise mapping of neural structures responsible for cognitive functions and the development of new theoretical models of mental activities.The diffusion of new pathologies (for example the pattern of cognitive impairment associated with AIDS) has further enlarged the field of clinical neuropsychology. Finally there has been an expanding clinical interest in the understanding and management of age-related cognitive changes

Right hemisphere developmental learning disability: A case study
No full textWe report a case study of a 22-year-old man with a developmental learning disorder consisting of arithmetic difficulties, visuo-spatial deficits and emotional difficulties. Language abilities and verbal learning were remarkably spared. The clinical picture was consistent with the diagnosis of 'Right Hemisphere Developmental Learning Disability' (RHDLD) as described by Weintraub and Mesulam (Archives of Neurology 1983; 40: 463-8). Computed tomography and magnetic resonance imaging scans were normal, but a positron emission tomography scan revealed a marked hypometabolism of the right hemisphere, supporting the claim that RHDLD is indeed associated with functional abnormalities of the right hemisphere
INNER SPEECH IN ANARTHRIA - NEUROPSYCHOLOGICAL EVIDENCE OF DIFFERENTIAL-EFFECTS OF CEREBRAL-LESIONS ON SUBVOCAL ARTICULATION
No full textThe role of articulation in verbal short-term memory was investigated in two anarthric patients, C.M. and F.C., both showing normal comprehension for written and spoken language, above average intelligence and visuo-spatial abilities. Based on experimental results, we propose that subvocal articulation might be impaired in anarthric patients in different ways, according to the site of lesion: in 'locked-in' patients only the articulatory rehearsal processes necessary to enhance memory performances is involved, while in cortical anarthric patients the lesion affects the articulatory recoding processes involved in transferring visually presented material into an articulatory form for better retention
Consciousness and Aphasia
No full textDifferent language impairments allow us to investigate how much the use of language can influence the content of conscious awareness and therefore of thinking and reasoning. Pure anarthria (differently form mutism) and verbal short-term memory deficits are associated with an impairment of the effect of covert speech on the content of working memory. Dynamic aphasia impairs the processes involved in the transition between thinking and speaking. However, even the most severe agrammatic patients can retain reasoning about others ’ beliefs that according to some theories can only take place in explicit sentences of a natural language.Error monitoring is also impaired in many aphasic patients and in some of them is associated with complete lack of error awareness (anosognosia for aphasia)
