Blood-based biomarkers for Alzheimer disease: mapping the road to the clinic.

Biomarker discovery and development for clinical research, diagnostics and therapy monitoring in clinical trials have advanced rapidly in key areas of medicine - most notably, oncology and cardiovascular diseases - allowing rapid early detection and supporting the evolution of biomarker-guided, precision-medicine-based targeted therapies. In Alzheimer disease (AD), breakthroughs in biomarker identification and validation include cerebrospinal fluid and PET markers of amyloid-β and tau proteins, which are highly accurate in detecting the presence of AD-associated pathophysiological and neuropathological changes. However, the high cost, insufficient accessibility and/or invasiveness of these assays limit their use as viable first-line tools for detecting patterns of pathophysiology. Therefore, a multistage, tiered approach is needed, prioritizing development of an initial screen to exclude from these tests the high numbers of people with cognitive deficits who do not demonstrate evidence of underlying AD pathophysiology. This Review summarizes the efforts of an international working group that aimed to survey the current landscape of blood-based AD biomarkers and outlines operational steps for an effective academic-industry co-development pathway from identification and assay development to validation for clinical use.I recieved an honorarium from Roche Diagnostics for my participation in the advisory panel meeting leading to this pape

The singer or the singing: Who sings individually to persons with dementia and what are the effects?

"Live" singing to persons with dementia (PWDs) may be an underused but highly accessible resource for their caregivers, regardless of qualifications. A systematic literature review sought to illuminate who sings to PWDs, and with what objectives and effects, to address the question of whether it is the singer or the singing which is effective. The literature revealed that music therapists seek to address cognitive, behavioral, physiological, and social factors through one-to-one singing, whereas other caregivers are more broadly concerned with quality of life, often through facilitating activities of daily living. All included studies concurred that individual singing to PWDs can be effective in a variety of ways, depending on contexts and goals. PWD's perceptions of situations may influence the effectiveness of singing interventions. Music therapists are urged to empower professional caregivers to sing sensitively to PWDs during caregiving activities. © The Author(s) 2010

Geriatric Psychology and the Injured Elderly.

Psychological disorders impact the care of the elderly trauma patient. Dementia is a cognitive disorder with many subtypes. Screening tests can help diagnose the impairment and treatments focus on symptoms. Delirium is all too common in the hospitalized elderly. Diagnostic tools exist but identification and modification of risk factors to prevent delirium are essential. Depression and substance abuse not only affect outcomes in the injured elderly but can contribute to causing trauma
