Summary
Accurate chemosensory testing is crucial for diagnosing taste and smell disorders. Quantitative assessment helps verify patient complaints and guides treatment, especially in older adults where dysfunction may signal serious health issues.
Area of Science:
- Neuroscience
- Otolaryngology
Background:
- Many patients report taste and smell disorders, yet quantitative chemosensory testing is infrequently performed by medical practitioners.
- This contrasts with the standard practice for evaluating visual, hearing, or balance impairments.
Purpose of the Study:
- To highlight the importance of accurate chemosensory testing for diagnosis, patient counseling, and treatment monitoring.
- To review current methods for assessing smell and taste function.
Main Methods:
- This review synthesizes information on available chemosensory assessment techniques.
- It includes updated normative data and discusses the clinical application of these tests.
Main Results:
- Objective assessment is vital to confirm the extent and validity of reported chemosensory dysfunction.
- Olfactory dysfunction is common in the elderly and can be an early indicator of neurodegenerative diseases like Alzheimer's and Parkinson's.
- Older adults with olfactory dysfunction face a significantly higher mortality risk.
Conclusions:
- Accurate chemosensory testing is essential for proper diagnosis and management of taste and smell disorders.
- Early detection of olfactory dysfunction in older adults can inform crucial nutritional and safety counseling, potentially improving outcomes.
- This review provides clinicians and researchers with a comprehensive overview of chemosensory assessment tools.

Functional Groups
89.0K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Functionalism
2.6K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.

Measuring Reaction Rates
30.3K
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...

Mechanical Protein Functions
5.7K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
