Assessing physical status in Alzheimer disease research

Alzheimer Disease and Associated Disorders

Abstract

In Alzheimer disease (AD), physical health problems can result from coexisting illness that is independent of the AD or can result directly from the consequences of the brain disease. Most of these physical health problems are not unique to AD, but they may have more functional impact in adults with AD. Coexistent or comorbid diseases may contribute directly to the outcomes of medical treatment. In future effectiveness studies in AD, in addition to measuring the severity of the AD, the presence and severity of coexisting illness should also be evaluated. In addition to accounting for comorbidity as part of AD effectiveness research, the reduction of comorbid physical illness may also be a legitimate independent outcome measure to target in the effectiveness of the clinical care provided to patients with AD. Examples of existing measures of comorbidity include the Charlson comorbidity index and the Greenfield index of coexistent disease. These existing measures of comorbid medical illness focus on system diseases and may not be applicable to the types of comorbid problems important to the AD patient. Further understanding of coexistent illness in AD may require the development of new measures of the cumulative occurrence of como...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
