The importance of taste has been recently evaluated from the standpoint of quality of life, but few reports exist on the clinical status of taste disturbance. We classified taste disturbance by cause and studied the effect of treatment and recovery duration. Subjects were 321 patients with taste disturbance, i.e., 131 men and 190 women (mean age: 59.9 years). Electrogustometry (EGM) and filter paper disks (FPD) were used to assess taste function in all subjects. We also asked them all about the degree of symptoms using visual analog scale (VAS). Statistical analysis was done using the unpaired t-test, with p<0.05 considered significant. Patients were treated with zinc sulfate, ferrotherapy, herbal medicine, and minor tranquilizers. Causes of taste disturbance were classified into idiopathic, post-common-cold, drug-induced, psychogenic, constitutional, and iron deficiency. Idiopathic taste disturbance was the commonest cause (125 cases, 38.9%), followed by drug-induced (62 cases, 19.3%), and post common cold (38 cases, 11.8%). Drug induced and psychogenic taste disturbance have increased. Recovery from symptoms was 79/103 (76.7%) in idiopathic taste disturbance, 24/33 (72.7%) in post-common-cold, and 14/17 (82.4%) in iron deficiency. Recovery took 22.2 weeks. Recovery was 32/50 cases (62.4%) in drug induced, taking 48 weeks. For all causes, EGM and FPD results were not associated with the degree of symptoms. Both tests tended to show delayed improvement compared to symptoms. Cases taking more than 6 months from symptom onset to medical examination showed significantly lower improvement and longer recovery time than those taking 6 months on less (p = 0.04).

Taste disorders are caused by several factors, and there have been few reports concerning the clinical course of taste disorders. In this study, patients with taste disorders were classified into 10 groups according to causes, and they were retrospectively studied in terms of therapeutic effects. In total, 1059 patients (412 men and 647 women, mean age: 60.0 years) who complained of taste disorders were reviewed in our clinic. The patients were asked detailed questions about their history of symptoms, and their emotional status was assessed using a self-rating depression scale. In all subjects, taste functions were measured by electrogustometry (EGM) and filter paper disks (FPD). The grades of their symptoms were assessed with a visual analogue scale (VAS). In addition, the levels of serum iron, copper, and zinc were examined. The patients were treated with zinc sulfate, polaprezinc, iron preparation, herbal medicine, and minor tranquilizers according to the factors causing the taste disorders. The most frequent cause was idiopathic taste disorder (192 cases, 18.2%), the second was psychogenic (186 cases, 17.6%), and the third was drug-induced (179 cases, 16.9%). The recovery rate of the symptoms was 64/92 (70.2%) in post-common cold, 31/35 (88.6%) in iron deficiency, and 85/116 (73.3%) in zinc deficiency. In these groups, the rates of recoveries were better than in the other groups. The recovery period in drug-induced taste disorders was approximately twice as long as the recovery period in the other groups. In the patients who were able to start treatment within 6 months from the onset of taste disorder, the recovery rate was significantly higher and the therapeutic period was significantly shorter than in those who had the disorders for more than 6 months (p<0.05, respectively).
