In addition, dysnomia is the leading symptom in the semantic and logopenic variants of primary progressive aphasia (PPA), the language variant of frontotemporal lobar degeneration (FTLD), and is frequently observed even in the behavioral FTLD form. For instance, in Alzheimer’s disease (AD) dysnomia is a symptom that appears early in the symptomatic stages of the disease as indicated by the reported significant dysnomia in patients with mild neurocognitive disorder (MiND) due to AD. Even though a mild decline in word-finding capacity is related to aging, more severe naming deficits embody core symptoms of a number of ND. The assessment of naming capacity is important for diagnosing neurocognitive disorders (ND) and may contribute to identifying their cause.

Gaining insights into naming tests’ characteristics may catalyze the wide incorporation of those with short administration time but high diagnostic accuracy into the diagnostic workup of ND at primary healthcare and of extensive, visual or auditory ones into the diagnostic endeavors of memory clinics, as well as of secondary and tertiary brain healthcare settings. Seven instruments are open access and four are available in more than one language. In all but one test, scoring systems are exclusively based on correctly named items. The average frequency of the words of each considered test was two or lower, pointing to low frequency of most items. Their content and administration time vary between three and 60 items and one and 20 minutes, respectively. Twelve naming tests, relying either on visual or auditory stimuli have been validated in ND.

Based on computational word frequency calculations, the tests were compared in terms of the average frequency of their linguistic content. A narrative- and tabullar synthesis was used to summarize different aspects of the naming assessment instruments used in patients with ND such as stimuli type, administration time,Īssessment parameters and accessibility. Only peer-reviewed journal articles were eligible.

Additional studies were identified by searching reference lists. Searches were carried out across Pubmed, Medline and Google Scholar. Here, features of naming tests with validated utility in ND which are open access or available for purchase are succinctly presented and compared. A.Ĭlinical practice- oriented overview of naming tests validated in ND is not available yet. Detecting impaired naming capacity is valuable in diagnosing neurocognitive disorders (ND).
