Complete or severe loss of the subjective sense of taste, frequently accompanied by OLFACTION DISORDERS.
Conditions characterized by an alteration in gustatory function or perception. Taste disorders are frequently associated with OLFACTION DISORDERS. Additional potential etiologies include METABOLIC DISEASES; DRUG TOXICITY; and taste pathway disorders (e.g., TASTE BUD diseases; FACIAL NERVE DISEASES; GLOSSOPHARYNGEAL NERVE DISEASES; and BRAIN STEM diseases).

Nuclear bilateral Bell's palsy and ageusia associated with Mycoplasma pneumoniae pulmonary infection. (1/13)

This case report describes a case of nuclear bilateral Bell's palsy and ageusia associated with Mycoplasma pneumoniae infection. Magnetic resonance imaging evidenced T2-weighted hyper-intense protuberantial lesions. Such topography leading to a nuclear palsy contrasts with previously reported infectious diplegia involving only peripheral facial nerves, and has not yet been described in the spectrum of M. pneumoniae post-infectious neurological manifestations.  (+info)

Transient hemiageusia in cerebrovascular lateral pontine lesions. (2/13)

Knowledge of human central taste pathways is largely based on textbook (anatomical dissections) and animal (electrophysiology in vivo) data. It is only recently that further functional insight into human central gustatory pathways has been achieved. Magnetic resonance imaging studies, especially selective imaging of vascular, tumoral, or inflammatory lesions in humans has made this possible. However, some questions remain, particularly regarding the exact crossing site of human gustatory afferences. We present a patient with a pontine stroke after a vertebral artery thrombosis. The patient had infarctions in areas supplied by the anterior inferior cerebellar artery and showed vertical diplopia, right sided deafness, right facial palsy, and transient hemiageusia. A review of the sparse literature of central taste disorders and food preference changes after strokes with a focus on hemiageusia cases is provided. This case offers new evidence suggesting that the central gustatory pathway in humans runs ipsilaterally within the pons and crosses at a higher, probably midbrain level. In patients with central lesions, little attention has been given to taste disorders. They may often go unnoticed by the physician and/or the patient. Central lesions involving taste pathways seem to generate perceptions of quantitative taste disorders (hemiageusia or hypogeusia), in contrast to peripheral gustatory lesions that are hardly recognised as quantitative but sometimes as qualitative (dysgeusia) taste disorders by patients.  (+info)

A randomized phase III prospective trial of bethanechol to prevent mucositis, candidiasis, and taste loss in patients with head and neck cancer undergoing radiotherapy: a secondary analysis. (5/13)

The aim of this study was to determine the impact of bethanechol administration concomitant to radiotherapy (RT) on oral mucositis, candidiasis and taste loss. We performed a secondary analysis of a previously conducted prospective randomized trial which evaluated the effect of bethanechol on salivary gland dysfunction before, during, and after RT for head and neck cancer (HNC), in comparison to artificial saliva. Mucositis, candidiasis and taste loss were analyzed in 36 patients. Mucositis was scored using the World Health Organization (WHO) method; candidiasis was diagnosed by means of clinical examination, whereas taste loss was assessed by the patients' subjective report of absence of taste. No significant differences were observed between groups in relation to frequency and severity of mucositis or frequency of candidiasis and taste loss. In conclusion, bethanechol does not appear to reduce the incidence of mucositis, candidiasis, and taste loss when administered during RT.  (+info)

Application of umami taste stimulation to remedy hypogeusia based on reflex salivation. (6/13)

Enjoying taste should be one of the greatest pleasures in human life. However, aging is sometimes associated with decreased taste sensitivity, also known as hypogeusia. The loss of taste not only affects quality of life, but can also cause weight loss and health problems in the elderly. Our recent study has shown that 37% of test subjects over 65 years of age exhibited hypogeusia. Further, whole saliva secretion, including minor salivary secretion, was significantly decreased in elderly patients with gustatory impairment, but was normal in all elderly subjects with normal taste thresholds. These data indicate that hyposalivation is closely related to hypogeusia. Moreover, clinical studies have shown that treatment of hyposalivation diminishes hypogeusia, indicating that salivation is essential to maintain normal taste function. However, many medications for relief of dry mouth, such as parasympathomimetic (cholinomimetic) drugs, have serious adverse effects. Palpitation, sweating, nausea, diarrhea and dizziness have all been observed in elderly patients taking parasympathomimetic drugs. To circumvent this problem, glutamate, which produces umami taste, was demonstrated to increase salivary secretion and thereby improve hypogeusia by enhancing the gustatory-salivary reflex. Our data suggests that umami is an effective tool for the relief of hypogeusia without the side effects of parasympathomimetic drugs.  (+info)

Evaluation of taste acuity by the filter-paper disc in Japanese young women: the relationship with micronutrients status. (8/13)

The aim of the present study is to investigate the taste acuity in Japanese young women in relation to their micronutrient status. Thirty-eight healthy young women (mean age; 21.3, range; 19-27 years) were enrolled. Gustatory thresholds were estimated for four basic tastes: sweet (sucrose), salty (sodium chloride), sour (tartaric acid), and bitter (quinine hydrochloride) by a filter-paper disk method. Various concentrations at each taste were serially scored from disc number 1 (lowest) to number 5 (highest). The lowest concentration at which the quality of the taste was correctly identified was defined as the recognition threshold. The mean of three measurements for each test on three different days was calculated. We divided our participants into normal taste and hypogeusia groups based on the mean threshold disc numbers, <=3.5 and >3.5, respectively, according to previous literature using the same method. We also measured serum concentrations and dietary intakes of micronutrients including zinc, iron, copper, and selenium. The numbers of participants belonging to the hypogeusia group were 24 (63.2%) for sweet, 19 (50.0%) for sour, 17 (44.7%) for bitter, and 16 (42.1%) for salty taste. Although the hypogeusia group exhibited significantly lower serum iron concentrations, except for the salty taste, the other three micronutrients concentrations did not show any association with the four taste acuities. Dietary micronutrient intake did not show any association with the four taste acuities. This study indicates that in addition to zinc status, iron status should be considered in the study of taste acuity.  (+info)

Ageusia is a medical term that refers to the complete loss of taste. It can affect a person's ability to detect sweet, salty, sour, bitter, and savory flavors. Ageusia can be caused by various factors such as damage to the nerves responsible for transmitting taste signals to the brain, exposure to certain chemicals or radiation therapy, and some medical conditions like diabetes, hypertension, and upper respiratory infections. In some cases, ageusia may be temporary, while in others, it can be permanent. It is important to consult a healthcare professional if experiencing a loss of taste, as it could be a sign of an underlying health issue.

Taste disorders, also known as dysgeusia, refer to conditions that affect a person's ability to taste or distinguish between different tastes. These tastes include sweet, sour, salty, bitter, and umami (savory). Taste disorders can result from damage to the taste buds, nerves that transmit taste signals to the brain, or areas of the brain responsible for processing taste information.

Taste disorders can manifest in several ways, including:

1. Hypogeusia: Reduced ability to taste
2. Ageusia: Complete loss of taste
3. Dysgeusia: Distorted or altered taste perception
4. Phantogeusia: Tasting something that is not present
5. Parageusia: Unpleasant or metallic tastes in the mouth

Taste disorders can be caused by various factors, including damage to the tongue or other areas of the mouth, certain medications, infections, exposure to chemicals or radiation, and neurological conditions such as Bell's palsy or multiple sclerosis. In some cases, taste disorders may be a symptom of an underlying medical condition, such as diabetes or kidney disease.

Treatment for taste disorders depends on the underlying cause. If a medication is causing the disorder, adjusting the dosage or switching to a different medication may help. In other cases, treating the underlying medical condition may resolve the taste disorder. If the cause cannot be identified or treated, various therapies and strategies can be used to manage the symptoms of taste disorders.
