Alexithymia and aging: a neuropsychological perspective.

Consistent with the emotional changes associated with later life, higher alexithymia scores are widely reported in older adults, but their significance has not been fully examined. We posited that association between alexithymia and poorer neurocognition would support the deficit nature of alexithymia in later life. Widely used neurocognitive tests assessing the relative integrity of the left and right hemisphere functions were used to examine the extent to which alexithymia of older age is associated with poor left or right hemisphere functioning.

BioMEA: a versatile high-density 3D microelectrode array system using integrated electronics.

Microelectrode arrays (MEAs) offer a powerful tool to both record activity and deliver electrical microstimulations to neural networks either in vitro or in vivo. Microelectronics microfabrication technologies now allow building high-density MEAs containing several hundreds of microelectrodes. However, dense arrays of 3D micro-needle electrodes, providing closer contact with the neural tissue than planar electrodes, are not achievable using conventional isotropic etching processes.

Evaluation of white matter damage in patients with Alzheimer's disease and in patients with mild cognitive impairment by using diffusion tensor imaging.

Purpose: The objective of this study was to evaluate white matter tissue damage in patients with Alzheimer's disease (AD) and in patients with mild cognitive impairment (MCI) using diffusion tensor imaging (DTI).

Materials And Methods: Forty-seven subjects were evaluated: 14 patients with AD, 15 with MCI and 18 healthy volunteers. All subjects were studied using conventional magnetic resonance imaging (MRI) and DTI (32 directions) with a 1.

Effectiveness of telecare in elderly populations-a comparison of three settings.

The primary aim of this study was to assess the level of satisfaction with 3 types of formal care systems of the elderly: (1) a day care center, (2) a nursing home, and (3) telecare service in a group of oldest frail elderly, and to describe the characteristics of the population using the services. The study involved a population of 162 oldest elderly using 3 different types of formal care services. Study participants were asked to complete a questionnaire, investigating socio-demographic characteristics and degree of overall satisfaction with the service, as well as eliciting possible suggestions for improvement.

Rivastigmine in the treatment of Alzheimer's disease: an update.

Alzheimer's disease is the most common form of dementia in industrialized countries. In the European Union, about 54% of dementia cases are believed to be due to Alzheimer's disease. The condition is an age-related neurodegenerative disorder characterized by multiple cognitive deficiencies, including loss of memory, judgment, and comprehension.
