Self-reported aural symptoms, headache and temporomandibular disorders in Japanese young adults.

BACKGROUND: To investigate the associations of aural symptoms, headache and depression with the presence of temporomandibular disorder (TMD) symptoms in a young adult population in Japan. METHODS: A personal interview survey was conducted on first-year university students (n = 1,930) regarding symptoms of TMD, aural problems, headache, shoulder pain and depression. Logistic regression was applied to assess the associations of these problems with the presence of TMD symptoms after controlling for age and gender. RESULTS: Among the 1,930 students, 543 students exhibited TMD symptoms and were classified into 7 groups: clicking only (Group I, n = 319), pain in the TMJ only (Group II, n = 21), difficulty in mouth opening only (Group III, n = 18), clicking and pain (Group IV, n = 29), clicking and difficulty in mouth opening (Group V, n = 48), difficulty in mouth opening and pain (Group VI, n = 11), and combination of three symptoms (Group VII, n = 97). The control group (n = 1,387) were subjects without any TMD symptoms. After adjusting for age and gender, a strong association was observed between TMD symptoms (Group II and IV) and tinnitus (OR = 12.1 and 13.2, respectively). TMD symptoms (Group I, II and III) were also associated with vertigo and headache. Otalgia and depression were significantly associated with the presence of clicking only. CONCLUSIONS: TMD symptoms were significantly correlated to aural symptoms and headache. A functional evaluation of the stomatognathic system should be considered in subjects with unexplained aural symptoms and headache.

Beliefs and emotional reactions in patients with benign paroxysmal positional vertigo: a longitudinal study.

OBJECTIVE: Psychologic studies in patients with benign paroxysmal positional vertigo (BPPV) are scarce, considering the high frequency of the disorder. We performed a repeated-measures design questionnaire study in a cohort of patients with BPPV before and after treatment to investigate the dynamics of the psychologic findings and possible treatment consequences. METHODS: Thirty-seven consecutive patients with idiopathic BPPV participated in the study. During the first visit and 2 to 3 months after therapy, the patients completed 4 questionnaires: the Dizziness Handicap Inventory, the Illness Perception Questionnaire-Revised, the Intolerance of Uncertainty Scale, and the State-Trait Anxiety Inventory. RESULTS: The scores for all questioned items did not change before and after treatment except for the physical handicap scores. Correlation was found between the grade of functional and emotional impact of the disease and belief in consequences as well as anxiety levels of the patients. Moreover, uncertainty scores were in correlation with emotional impact, anxiety levels, and perceived consequences of the disease. The belief in personal control of the condition was correlated with the belief in treatment control and understanding of the disease. CONCLUSION: The main finding in this study is the lack of a significant change in beliefs and emotional reactions in patients with BPPV after treatment of their condition. Physicians dealing with BPPV should be aware that the disease is not solely a somatic condition but has a serious impact on the patient's mental state. Selected patients might benefit from anxiolytic medication.

Psychological manifestations of vertigo: a pilot prospective observational study in a Portuguese population.

We sought to ascertain the importance of psychological manifestations of vertigo and psychogenic vertigo among a Portuguese population. Sixty patients complaining of vertigo and imbalance were studied over a 2-year period. At each assessment, the patients underwent a general examination, a neurootological evaluation, psychiatric interviews, and psychopathological assessments conducted by a multidisciplinary team. Overall, 38 patients (63.4%) were given diagnoses of some form of psychopathological complaint. A more detailed analysis revealed panic disorder in 9, moderate depressive episode in 42, and mixed anxiety and depressive disorder in 7, whereas the remaining patients (2) suffered from subclinical symptoms of anxiety or depression. Patients with vertigo demonstrate a high incidence of psychopathological complaints, the most common being anxiety disorders. Somatization, obsessive-compulsive behaviors, and depression tend to lessen over time, whereas few changes are seen in anxiety.

The prevalence of dizziness and its association with functional disability in a biracial community population.

BACKGROUND: Information regarding the prevalence of dizziness and its association with functional disability among African American and white residents from defined community populations is limited. METHODS: A total of 6,158 persons 65 years and older (78.8% of age-eligible persons) completed in-home interviews that included three common measures of self-reported disability: the Katz Activities of Daily Living (ADL) Scale, the Rosow-Breslau Functional Health Scale, and the Nagi Physical Disability Scale. A stratified random sample of 729 persons underwent a detailed evaluation that included questions on the frequency and severity of dizziness, which was defined as having an episode of dizziness or lightheadedness at least once a month. RESULTS: The overall prevalence of dizziness in this population was 9.6% (95% confidence interval [CI] 7.2-12.0). It increased with age, from 6.6% in those 65-74 years old, to 11.6% in those 75-84 years old, and to 18.4% in those persons > or =85 years old. It was more common in women (odds ratio [OR] 2.03, 95% CI 0.99-4.19) but was not associated with race. After adjusting for age, sex, and race, dizziness was associated with greater disability on the Rosow-Breslau (OR 2.29, 95% CI 1.18-4.46) and Nagi (OR 2.54, 95% CI 1.48-4.36) measures but not on the Katz ADL Scale (OR 1.18, 95% CI 0.64-2.20). CONCLUSIONS: Dizziness is common among older persons and is associated with functional disability.
