Degenerative Amnesia for Past Public Events: An Attempt to Measure Storage and Retrieval.

A still unsettled issue of amnesia concerns the differential contributions to recall impairment of the underlying retrieval and storage abilities. The aim of the present study was to disentangle and to measure such roles in the recall of past public events comparing patients with degenerative amnesia and healthy elderly. The experiment included 44 healthy elderly and two groups of participants with degenerative amnesia, namely 17 patients with amnestic mild cognitive impairment and 22 mild Alzheimer's disease patients.

Long-term proper name anomia after removal of the uncinate fasciculus.

A previous study reporting on 44 patients who underwent awake surgery for a left frontal or temporal glioma resection demonstrated the removal of the uncinate fasciculus to have consequences on language 3 months post-surgery. At this time-point, patients with a temporal glioma who had undergone uncinate removal showed the worst overall performance with a significant impairment in naming of famous faces and objects compared to patients without removal. Also, verbal fluency was mildly impaired.

Autobiographical memory in amnestic Mild Cognitive Impairment.

Autobiographical memory (ABM) was evaluated in 19 patients with amnestic Mild Cognitive Impairment (aMCI) by means of the standardized enquiry developed by Borrini et al. (Psychol Med 19:215-224, 1989). Longitudinal assessments were carried out by re-testing participants at 9-month intervals up to three assessments over 18 months.

Ambiguous idiom comprehension in Alzheimer's disease.

Ambiguous idiom comprehension was examined in 15 patients with mild probable Alzheimer's disease (AD) by means of two tasks: a string-to-picture matching task and a string-to-word matching task. In the first, patients had to choose among four pictures, while in the second they chose among four words. For both tasks the alternatives were the picture/word corresponding to the figurative meaning, a semantic associate (picture/word) to the last word of the idiom, and two unrelated alternatives, which were, in the case of words, an unrelated foil preserving the semantic class and a literal continuation foil (a word that can follow the verb in that sentence), while in the case of pictures the first was substituted by an unrealistic foil.

Mild cognitive impairment does entail retrograde amnesia for public events.

In this study memory for public events was evaluated in 15 amnesic mild cognitive impairment (aMCI) patients, whose clinical diagnosis was refined through a stringent selection procedure. A total of 9 patients were longitudinally reassessed over an 18-month period. About half of the participants were impaired at baseline and nearly 80% at the end of the 18-month follow-up.

Phonological recoding, visual short-term store and the effect of unattended speech: evidence from a case of slowly progressive anarthria.

Phonological processing and short-term memory were investigated in a patient with slowly progressive anarthria. The patient, who had an auditory-verbal span in the lower unimpaired range, showed preserved phonological similarity and word length effects with auditory presentation. These phonological effects of immediate retention were absent with visual input.

A reappraisal of person recognition and identification.

In the last years an increasing number of cases (Gainotti et al., 2008, this issue) have been reported in whom difficulty to recognise and identify familiar people occurs in everyday multimodal settings, differently from unimodal face-specific impairments (i.e.

Recollection of public events in healthy people: a latent-variable stochastic approach to disentangling retrieval and storage.

Recollection of media-mediated past events was examined in 96 healthy participants to investigate the interaction between the age of the subject and the "age" of memories. The results provided evidence that people older than 75 years recall recent events significantly worse than remote ones. Younger participants (47-60 years old) showed the reverse pattern.

Is slowly progressive anarthria a "pure" motor-speech disorder? Evidence from writing performance.

It is usually assumed that writing is normal in patients with anarthria, but a careful examination of the literature shows that they produce deletions, transpositions and insertions. Indeed, a matter of debate concerns the distinction between primary progressive aphasia (PPA) and slowly progressive anarthria (SPA). If writing deficits were purely linguistic errors, then there would be no reason to consider slowly progressive anarthria as distinct from non-fluent PPA.

Idiom comprehension in Alzheimer's disease: the role of the central executive.

Idiom comprehension of 15 patients with mild probable Alzheimer's disease was examined by means of a sentence-to-picture matching task. Patients had to choose between two pictures, one representing the figurative and the other the literal interpretation. They were also submitted to a literal sentence comprehension test and to a pencil-and-paper dual task.
