The working memory model proposed by Baddeley and Hitch has frequently been used in cognitive psychology and neuropsychological studies. This model consists of several interacting components, responsible for the storage and processing of the information stored in working memory. Many neuropsychological and functional imagery data are consistent with that formulation of working memory. Moreover, many cognitive tasks have been specifically designed to explore particular aspects of working memory functioning. Taken as a whole, these data confirm that the working memory model remains a useful theoretical framework to explore memory functioning both in normal subjects and in pathological conditions.

Memory in not a unified system. It's composed of independant but interacting systems. Cognitive neuropsychology showed dissociations between these systems in patients with various brain lesions. The episodic memory system is devoted to the processing of personally lieved events. The predominant role played by frontal regions in underlying episodic memory has been fully documented. Moreover, the episodic memory disfunctions may lead to illusions of memory such as false memories, confabulations or hallucinations. [less ▲]

Humans, like numerous other species, strongly rely on the observation of gestures of other individuals in their everyday life. It is hypothesized that the visual processing of human gestures is sustained by a specific functional architecture, even at an early prelexical cognitive stage, different from that required for the processing of other visual entities. In the present PET study, the neural basis of visual gesture analysis was investigated with functional neuroimaging of brain activity during naming and orientation tasks performed on pictures of either static gestures (upper-limb postures) or tridimensional objects. To prevent automatic object-related cerebral activation during the visual processing of postures, only intransitive postures were selected, i.e., symbolic or meaningless postures which do not imply the handling of objects. Conversely, only intransitive objects which cannot be handled were selected to prevent gesture-related activation during their visual processing. Results clearly demonstrate a significant functional segregation between the processing of static intransitive postures and the processing of intransitive tridimensional objects. Visual processing of objects elicited mainly occipital and fusiform gyrus activity, while visual processing of postures strongly activated the lateral occipitotemporal junction, encroaching upon area MT/V5, involved in motion analysis. These findings suggest that the lateral occipitotemporal junction, working in association with area MT/V5, plays a prominent role in the high-level perceptual analysis of gesture, namely the construction of its visual representation, available for subsequent recognition or imitation.

Discusses the neurophysiological functions of the prefrontal cortex related to memory processes. Functional brain imaging studies have revealed that distinct regions of the prefrontal cortex are engaged in episodic memory operations, with some regions apparently part of multiple networks subserving different memory abilities. The prefrontal cortex is also involved in shifting processes. Working memory processes within the dorsolateral and ventrolateral frontal cortex are organized according to the type of processing required rather than the nature of the information being processed. The binding of contextual information, both incidentally and intentionally, is the most crucial process involved in episodic memory. Inhibition control involves not only bilateral prefrontal areas, but also posterior regions and subcortical structures, but the specific role of the cerebral areas is not clear at present. [less ▲]

The presence of correlations between cerebral metabolism and performance on cognitive tasks (digit span, verbal fluency, Hayling inhibition task and the Mattis dementia rating scale) was assessed in AD patients and elderly controls. Results showed that in both groups the cerebral areas where metabolism was correlated to performance were similar to those found in functional activation studies with young healthy subjects. The comparison of cognitivo-metabolic correlations in AD patients and control subjects showed that the single significant difference was a correlation between posterior cingulate metabolism and performance on the Mattis dementia rating scale in AD patients only. These results are consistent with two neurobiological causes of cognitive impairment in AD : a less efficient functioning of some areas involved in specific cognitive tasks and a deficit of integration of information coming from different areas.

The day care centre appears to be a structure especially well suited for the management of mild to moderate Alzheimer patients. It constitutes a place in which performance in everyday life activities can be explored, and optimisation strategies can be installed before they are used at home. Another objective of the day care centre might also be to provide caregivers with support and ease the burden that the daily care of a demented patient represents. Finally, it may also help to alleviate the patient's loneliness. In this perspective, we describe the general organisation of the recently-created day care centre at the University Hospital of Liege. We also present the assessment and intervention programme which was conducted in this day care centre in order to reduce the generalised apathy and depressed mood observed in a 70-year-old Alzheimer patient (AM). This programme aimed at restoring a leisure activity (knitting) at home by proposing several adaptations designed to minimise the impact of AM's cognitive deficits on knitting activity. While an aggravation of her memory deficits was observed, the intervention significantly decreased AM's apathy and depressed mood as well as her husband's burden. [less ▲]

A case of early-onset adult dementia with family history of dementia is reported, characterised by neuropsychological deficits, suggesting frontal involvement, with mild non specific white matter abnormalities on CT scan. Familial Alzheimer's disease was suspected but the neuropathological diagnosis on brain biopsy was metachromatic leukodystrophy. 18FDG-PET revealed a very peculiar pattern of metabolic impairment in thalamic areas, in medial and frontopolar regions, and in occipital lobes. Neuropsychological follow-up showed relatively stable difficulties of long-term memory and signs of frontal lobe dysfunction, similar to those observed in subcortical dementias. MRI subsequently showed periventricular leukoencephalopathy. The brain metabolic pattern observed in that case of metachromatic leukodystrophy was quite different from that reported in other types of dementia. [less ▲]

The phonological loop and central executive functioning were examined in patients with Alzheimer's disease (AD) and in normal elderly subjects. AD patients showed abnormal functioning of the phonological loop and decreased performance on tasks assessing the central executive. However, when AD patients were separated into two groups on the basis of their span level, both groups showed deficits of the central executive but only patients with the lower span level presented a dysfunction of the phonological loop as well as impaired performance in tasks of phonological discrimination, articulation rate and speed of processing. These results are interpreted in terms of progression of the disease, with high-span level patients being less severely demented and displaying deficits only in higher-level cognitive functions (such as manipulation of information stored in working memory) whereas patients with a low span level have impairments encompassing a series of more basic processes.
