This complex task starts with the recognition and perception of an object and ends with articulating the words that describe it (Fig. magnetic resonance imaging, positron emission tomography, electroencephalogram). Naming of objects is a multifaceted process which has been deciphered through various imaging techniques (e.g. In line with its presence in different clinical entities, dysnomia does not pertain either to pathological alterations in a single brain region or to a one-size-fits-all pathomechanism. Hence, assessment of naming capacity is an important part of the ND diagnostic workup and a valuable tool in detecting their cause. In contrast, the subcortical vascular dementia and Huntington’s disease do not typically include naming deficits. Furthermore, mild traumatic brain injury and further acquired brain injuries may also lead to dysnomia.

Moreover, naming deficits can precede full blown major neurocognitive disorder (MaND) due to Lewy bodies and Parkinson’s disease and can belong to the clinical manifestations of vascular lesions in the language-dominant hemisphere. 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).
