El espectro de enfermedades neurodegenerativas que afectan principalmente a la cognición y el comportamiento abarca desde la enfermedad preclínica asintomática hasta el deterioro cognitivo muy leve y la demencia franca. En este artículo se procedió a  la revisión  de los criterios actuales para el diagnóstico de la demencia con cuerpos de Lewy, segunda causa más frecuente de demencia neurodegenerativa en personas mayores de 65 años luego de la enfermedad de Alzheimer (EA) y las afasias progresivas primarias que se distinguen por producir un compromiso temprano y aislado de las funciones lingüísticas, y en cuya evolución desarrollan un síndrome complejo caracterizado, además del compromiso del lenguaje, por la presencia de deterioro cognitivo progresivo, trastornos de conducta y compromiso de los sistemas motores. También pueden representar la forma de comienzo de una variante atípica de la enfermedad de Alzheimer (EA), no siendo raras las formas mixtas o no caracterizables.

Psychotic symptoms can manifest at any age, but in the elderly they represent a real diagnostic challenge. Thought disorders, hallucinations (usually visual), mood disorders with delusions, impairment of social interaction and occasionally verbal or physical aggression may be observed (Karon & VandenBos, 1998). Since the first descriptions of classical psychiatry, attempts have been made to define the psychoses observed in the elderly and determine whether they are primary "psychiatric" syndromes or, conversely, whether they can be attributed to other pathologies.

Relevance and Impact of Social Support on Quality of Life for Persons With Multiple Sclerosis.

Background: Social support is crucial for persons with multiple sclerosis (MS). We sought to analyze differences in perceived social support in persons with MS vs controls; to study associations between perceived social support, clinical measures, and health-related quality of life (HRQOL) variables in persons with MS; and to establish a predictive value of perceived social support for HRQOL.

Methods: We studied 151 persons with MS (mean ± SD: age, 42.

Employment status monitoring in an Argentinian population of patients with multiple sclerosis: Particularities of a developing country.
