The objective of this study was to obtain normative data for naming and semantic memory (SM) tests in the elderly Spanish population. A total of 121 Spanish-speaking senior citizens were assessed with the Boston Naming Test (BNT). Of these, 79 were assessed with the Semantic Fluency Test (Sem-Flu) and 72 with the Pyramids and Palm Trees Test (PPT). Mean(More)
INTRODUCTION The term cognitive reserve describes the capacity of the adult brain to minimise the clinical manifestation of a neurodegenerative process. The acquisition of cognitive reserve has been linked to the performance of certain intellectual and cognitive activities throughout the whole of the individual's life. AIMS To create a new cognitive(More)
AIMS To establish the discriminatory validity of the mini-mental test (MMSE) and the memory alteration test (M@T) for the diagnosis of amnestic mild cognitive impairment (aMCI) and probable Alzheimer's disease (AD), and also to study the association between the results obtained in screening tests, a neuropsychological battery and a functional questionnaire(More)
AIM To investigate the relationship between performance in language tests and levels of brain metabolites in two selected left temporal lobe regions. METHODS Ninety-five subjects were included: 26 controls, 30 amnestic mild cognitive impairment subjects, 27 Alzheimer's disease and 12 frontotemporal lobar degeneration (FTLD) patients. Language was assessed(More)
INTRODUCTION Visual episodic memory is affected in the early phases of Alzheimer's disease (AD). AIMS To design a visual memory test free of any verbal content, to offer its normative values in the elderly population in Spain, to validate the test in a group of patients with mild AD and to determine its capacity to discriminate between subjects with AD(More)
INTRODUCTION The term 'posterior cortical atrophy' (PCA) refers to a neurodegenerative syndrome that is characterised by progressive alteration of the higher visual-perceptual and/or visual-spatial functions, which often presents Alzheimer's disease (AD). AIM To describe the value of neuropsychological tests in the differential diagnosis of patients with(More)
The nonverbal learning disability (NLD) is a neurological dysfunction that affects cognitive functions predominantly related to the right hemisphere such as spatial and abstract reasoning. Previous evidence in healthy adults suggests that acoustic pitch (i.e., the relative difference in frequency between sounds) is, under certain conditions, encoded in(More)
BACKGROUND & OBJECTIVES Patients with schizophrenia usually present cognitive deficits. We investigated possible anomalies at filtering out irrelevant visual information in this psychiatric disorder. Associations between these anomalies and positive and/or negative symptomatology were also addressed. METHODS A group of individuals with schizophrenia and a(More)
INTRODUCTION Phenylketonuria (PKU) is a rare metabolic disease that causes slight-to-severe neurological symptoms. Slow performance has been observed in PKU but the influence of high-order (i.e., not purely motor) deficits and of temporary variations of the phenylalanine (Phe) level on this slowness has not been fully corroborated as yet. Response speed and(More)
