[Aggressive behaviour in dementia. RAGE scale, validation of the version in Spanish].

Introduction: Aggressive behaviours are frequent in the different phases of dementia s evolution. These not only constitute a major problem for the families and the caring staff, but cause fatigue and bur out among them. As these behaviours cannot be predicted or understood, the carers experience very complex and anguishing situations.

[Neuropsychological pattern of cognitive impairment in Alzheimer type dementia and vascular dementia].

Background: Cummings et al, 1987, hypothesized that Alzheimer dementia type (ADT) patients would present poorer performances than vascular dementia (VD) patients on the neuropsychological tests that mainly involve cortical neurological structures, and that VD would perform worse on tests that mainly involve subcortical structures. The main purpose of the research was to identify a cognitive impairment pattern that discriminates the type of dementia in the initial stages.

Method: Two groups of patients, one affected by mild ADT (n = 30) and the other by multi-infarct dementia (VD, n = 30) were given a neuropsychological battery.

[Clock drawing test: qualitative and quantitative evaluation methods].

Introduction: The interest about the Clock Drawing Test (CDT) is justified because the importance of praxic disorders and especially the constructive apraxias in demented patients. Generally, this kind of deficits or intellectual losses has been less studied than aphasisas and agnosias. Nevertheless, praxias are usually affected in demential processes, even in initial stages.
