“…A search of the literature yielded 16 cases of auditory agnosia that met these criteria. Of these, 4 were nonverbal auditory agnosics (Albert et al, 1972;De La Sayette et al, 1994;Habib et al, 1995;Taniwaki et al, 2000), 8 were verbal auditory agnosics (Buchman et al, 1986, cases 1 and 2;Coslett et al, 1984;Klein and Harper, 1956;Mendez and Rosenberg, 1991;Otsuki et al, 1998;E. Wang et al, 2000;Papathanasiou, 1998), and 4 were complete auditory agnosics (Garde and Cowey, 2000;Kaga et al, 2000;Michel et al, 1980;Rosati et al, 1982).…”

This special issue of Cortex focuses on the relative contribution of different neural networks to memory and the interaction of 'core' memory processes with other cognitive processes. In this article, we examine both. Specifically, we identify cognitive processes other than encoding and retrieval that are thought to be involved in memory; we then examine the consequences of damage to brain regions that support these processes. This approach forces a consideration of the roles of brain regions outside of the frontal, medialtemporal, and diencephalic regions that form a central part of neurobiological theories of memory. Certain kinds of damage to visual cortex or lateral temporal cortex produced impairments of visual imagery or semantic memory; these patterns of impairment are associated with a unique pattern of amnesia that was distinctly different from the pattern associated with medial-temporal trauma. On the other hand, damage to language regions, auditory cortex, or parietal cortex produced impairments of language, auditory imagery, or spatial imagery; however, these impairments were not associated with amnesia. Therefore, a full model of autobiographical memory must consider cognitive processes that are not generally considered 'core processes,' as well as the brain regions upon which these processes depend.

-Primary progressive aphasia (PPA) is an intriguing syndrome, showing some peculiar aspects that differentiate it from classical aphasic pictures caused by focal cerebral lesions or dementia. The slow and progressive deterioration of language occurring in these cases provides an interesting model to better understand the mechanisms involved in the linguistic process. We describe clinical and neuroimaging aspects found in 16 cases of PPA. Our patients underwent language and neuropsychological evaluation, magnetic resonance imaging (MRI) and single photon emission computerized tomography (SPECT). We observed a clear distinction in oral expression patterns; patients were classified as fluent and nonfluent. Anomia was the earliest and most evident symptom in both groups. Neuroimaging pointed to SPECT as a valuable instrument in guiding the differential diagnosis, as well as in making useful clinical and anatomical correlations. This report and a comparison to literature are an attempt to contribute to a better understanding of PPA.KEY WORDS: primary progressive aphasia, focal cortical degeneration, cerebral perfusion, neuroimaging. Afasia progressiva primária: análise de 16 casosRESUMO -A afasia progressiva primária (APP) é uma síndrome que tem despertado grande interesse devido a aspectos particulares que a diferenciam das afasias clássicas (secundárias a lesões cerebrais focais) e dos quadros demenciais. A deterioração lenta e progressiva da linguagem presente nesses casos fornece um interessante modelo de observação dos mecanismos subjacentes ao processamento linguístico. Descrevemos as características clínicas e de neuroimagem de 16 casos de APP. Os pacientes foram submetidos a exame de linguagem, neuropsicológico, ressonância magnética (RM) e tomografia computadorizada por emissão de fóton único (SPECT). Clinicamente pudemos observar uma nítida distinção nos padrões de produção oral, sendo os pacientes agrupados em fluentes e não-fluentes. Anomia foi o sintoma mais precoce e evidente nos dois subgrupos. Os achados de neuroimagem permitem destacar a sensibilidade do SPECT como instrumento diagnóstico. O registro e a comparação destes casos aos da literatura são uma tentativa de contribuir para a compreensão da APP. PALAVRAS-CHAVE: afasia progressiva primária, degeneração focal cortical, perfusão cerebral, neuroimagem.
