“…A higher score indicates better tasting recognition. Two studies used the closely related filter paper disc method (Nakai, Kinoshita, Koh, Tsujii, & Tsukada, 1987; Nozoe et al, 1996), measuring the ability to recognize sweet, bitter, salty, and sour at different concentration thresholds (Berling, Knutsson, Rosenblad, & von Unge, 2011). Circular filter paper discs are soaked in different taste solutions at five different concentrations and placed on the tongue.…”

ObjectiveThere is evidence for altered processing of taste in anorexia nervosa, particularly in the areas of reward processing and hedonic sensitivity. However, research on whether people with anorexia nervosa identify taste stimuli accurately, known as taste sensitivity, has yielded mixed findings. The objective of this study was to synthesize the literature on taste sensitivity in this disorder to provide a basis for future discussion on whether altered taste sensitivity may be also implicated in wider atypical taste processing in anorexia.MethodElectronic databases were searched systematically to identify published research examining taste sensitivity in anorexia. Search terms were “anorexia nervosa”, or “eating disorder”, combined with “taste”. 18 studies met inclusion criteria.ResultsThe review of the findings suggest that individuals with AN may experience reduced taste sensitivity that may improve following recovery. However, there was a significant variability in results across studies, potentially reflecting methodological problems including low sample sizes, experimental designs, and uncontrolled confounding variables. Discussion: This review suggests that altered taste sensitivity could represent a component in the wider altered taste processing observed in anorexia nervosa. However, the heterogeneity of findings highlight the need for future research to consider methodological issues raised by this review.

“…Screening may involve asking questions regarding changes in taste and eating practices, objective qualitative assessments of smell and taste, or formal testing with taste strips 38 or electrogustometry. 39 Individualized attention to patient nutrition and activity has been shown to reduce risk of weight loss and improve certain functional outcomes as well as overall quality of life in acute stroke patients at risk for malnutrition. 40 Dietary education, including the addition of flavor enhancers to food, may also be helpful.…”

Patients with altered taste perception following stroke are at risk for malnutrition and associated complications that may impede recovery and adversely affect quality of life. Such deficits often induce and exacerbate depressive symptomatology, which can further hamper recovery. It is important for clinicians and rehabilitation specialists to monitor stroke patients for altered taste perception so that this issue can be addressed. The authors present the case of a patient who experienced an isolated ischemic infarct affecting a primary cortical taste area. This case is unusual in that the isolated injury allowed the patient to remain relatively intact cognitively and functionally, and thus able to accurately describe her taste-related deficits. The case is further used to describe the relevant neurological taste pathways and review potential taste-related therapies.

“…Electrogustometry, the application of mild electric current to the oral surface, may be the best-known method for localized stimulation of the mouth [e.g., 150-152], but it has two key limitations. First, electrogustometry measures only taste thresholds, which fail to predict suprathreshold function at levels experienced in everyday life [153].…”

Oral sensations (i.e., taste, oral somatosensation, retronasal olfaction) are integrated into a composite sense of flavor, which guides dietary choices with long-term health impact. The nerves carrying this input are vulnerable to peripheral damage from multiple sources (e.g., otitis media, tonsillectomy, head injury), and this regional damage can boost sensations elsewhere in the mouth because of central interactions among nerve targets. Mutual inhibition governs this compensatory process, but individual differences lead to variation in whole-mouth outcomes: some individuals are unaffected, others experience severe loss, and some encounter sensory increases that may (if experienced early in life) elevate sweet-fat palatability and body mass. Phantom taste, touch, or pain sensations (e.g., burning mouth syndrome) may also occur, particularly in those expressing the most taste buds. To identify and treat these conditions effectively, emerging clinical tests measure regional vs. whole-mouth sensation, stimulated vs. phantom cues, and oral anatomy. Scaling methods allowing valid group comparisons have strongly aided these efforts. Overall, advances in measuring oral sensory function in health and disease show promise for understanding the varied clinical consequences of nerve damage.
