Las orexinas como biomarcadores para demencia tipo Alzheimer y relación con síntomas neuropsiquiátricos

RESUMEN: Los biomarcadores más estudiados en la demencia tipo Alzheimer (DA) son los niveles elevados de Aβ42 y de proteína Tau en líquido cefalorraquídeo. Dada la complejidad de la sintomatología cognitiva y síntomas neuropsiquiátricos (SNP) de esta patología, algunos estudios recientes pro...

Aβ promotes CD38 expression in senescent microglia in Alzheimer's disease

Biol. Res; 55 (), 2022
BACKGROUND: In Alzheimer's disease (AD), the neuroinflammatory response mediated by the activation of senescent microglia is closely related to energy dysmetabolism. However, the mechanism underlying the interaction between the energy metabolism of aging microglia and neuroinflammation remains unclear. M...

Influence of Alzheimer’s disease on the relationship between nutritional status and risk of fall

Acta sci., Health sci; 43 (), 2021
Although malnutrition and risk of falls in the elderly have increased in recent years, uncertainties exist as to whether these conditions are associated after controlling for sociodemographic variables, body composition, metabolic condition, and Alzheimer’s disease (AD)...

Salivary biomarkers in Alzheimer´s disease

Int. j. morphol; 38 (1), 2020
The hypotheses currently considered the most likely causes of Alzheimer's disease (AD) are amyloid beta peptide deposition in the cerebral cortex and hyperphosphorylation of the Tau protein, with the consequent formation of neurofibrillary tangles. In clinical practice, although not accurate, AD diagnosi...

Associations of Cerebrovascular Metabolism Genotypes With Neuropsychiatric Symptoms and Age at Onset of Alzheimer's Disease Dementia

Objective: To study associations of cerebrovascular metabolism genotypes and haplotypes with age at Alzheimer’s disease dementia (AD) onset and with neuropsychiatric symptoms according to each dementia stage. Methods: Consecutive outpatients with late-onset AD were assessed for age at dementia ons...

Aged Lewis rats exposed to low and moderate doses of rotenone are a good model for studying the process of protein aggregation and its effects upon central nervous system cell physiology

Arq. neuropsiquiatr; 74 (9), 2016
ABSTRACT Cell physiology is impaired before protein aggregation and this may be more relevant than inclusions themselves for neurodegeneration. The present study aimed to characterize an animal model to enable the analysis of the cell biology before and after protein aggregation. Ten-month-old Lewis rats...
