ABSTRACT

The phonemic/semantic alternate fluency test seems to overcome some limits of the instruments currently used to assess set-shifting abilities. In particular, this test does not make high demands on motor systems because the subject is required to rapidly change mental set to generate words by continuously alternating between phonemic and semantic criteria. Thus, it is potentially feasible for use in individuals who have movement disorders. In this regard, some data support its sensitivity in revealing cognitive impairments in people suffering from frontal-striatal-related disorders. The first aim of this study was to provide standardization and normative data for the phonemic/semantic alternate fluency test. The second aim was to upgrade normative data for the single phonemic and semantic fluency tests. For these purposes, we administered to a sample of 335 healthy Italian subjects (ranging from 20 to 90 years), a test consisting of the following three subtests: (1) a single letter-cued (phonemic) fluency subtest; (2) a single category-cued (semantic) subtest; (3) a phonemic/semantic alternate fluency subtest. A composite shifting index was also derived to capture the shifting cost a subject pays passing from performance of the two single fluency subtests to performance of the alternate fluency subtest. We computed correction grids to adjust raw scores for age, literacy and gender according to the results of regression analyses. Moreover, we computed equivalent scores to permit direct and fast comparison of performance on the three fluency tests.

ABSTRACT

BACKGROUND: Primary focal or segmental dystonia is a rare clinical condition including early-onset dystonia, which has the tendency to generalize, and late-onset dystonia, which may be focal or segmental. The prevalence of late-onset dystonia ranges from 30 to 7,320 cases per million, but no data are available in Italy. METHODS: A service-based study was conducted in the period 1 January 2001 through 31 December 2002 in the administrative district of Foggia, southern Italy (population 541,653). Cases were traced through hospital discharge diagnosis, botulinum toxin services, day hospital access, ear, nose and throat, ophthalmology and orthopedic surgery specialists, and territorial outpatient services. Inclusion criteria were age 17 years or older, residency in the study area and a diagnosis of primary focal/segmental dystonia. RESULTS: A total of 69 patients were included, giving a crude prevalence of 127.4 per 1,000,000 (women: 146.4; men: 107.0; age 18-34 years: 39.2; 35-54 years: 98.7; 55-74 years: 273.6; 75+ years: 163.3). The standardized rate was 137.5 (95% confidence interval 107.0-174.6). Blepharospasm was the commonest clinical condition (prevalence 68.2), followed by cervical dystonia (prevalence 44.8). CONCLUSION: The prevalence of primary focal or segmental dystonia in Italy is in keeping with several other reports, but is lower than in studies performed in northern Europe, Minnesota, USA, and Japan. The difference in our results may be mostly explained by misdiagnosis, underascertainment of cases and a fairly limited observation period.
