Objective: The current study establishes normative Sniffin' Sticks Odor Identification Test (SS-OIT) scores for cognitively intact older adults.
Method: Two hundred and twenty-six cognitively normal older adults were identified as eligible for the current study (Mean Age = 70.49 years; 71.7% female). Important demographic covariates were identified using step-wise regression, and a normative regression equation was developed.
Results: Analyses of the effects of demographic variables (including age, education, and sex) on SS-OIT performance revealed that age was the only significant predictor, b = -0.07, SEb = .01, p < .01. A final regression equation was determined and normative data are reported in 5-year increments for a number of percentile ranks.
Conclusions: Normative performance on the SS-OIT for adults over the age of 50 was established in a large and demographically diverse sample. These data are needed in order for clinicians to be able to include olfactory testing, a sensitive marker of neurodegeneration, in their assessment armamentarium.

The association of muscle weakness with poor outcomes is well defined in general older population, but there is insufficient data on the association of muscle weakness with functionality in older patients with diabetes mellitus (DM). We aimed to investigate the predictivity of muscle weakness defined as low grip strength thresholds determined by EWGSOP2, and two regional thresholds in older patients with DM for functional disability. Activities of Daily Living (ADL), Instrumental ADL (IADL), grip strength, comorbidities, anthropometric and biochemical data from outpatient clinic medical records were screened retrospectively.

Department of Psychology, National University of Singapore.
Lexico-semantic effects in lexical decision and semantic categorization tasks have been investigated using the megastudy approach, but not with other traditional spoken word recognition tasks. To address this gap, the present megastudy, using words from the McRae et al. (2005) norms, examined the single-word shadowing task, where 96 native English speakers repeated aloud each word they heard as quickly and as accurately as possible.

Objective: Anomia is defined by difficulty in retrieving content words like nouns and verbs from long-term memory, independent of any impairments related to articulatory movements or motor speech execution. The tools for measuring picture naming, the conventional method for assessing anomia, are very limited in Turkey. The aim of this study was to adapt the Test de Dénomination de Québec-60 images/Quebec picture-naming test-60 pictures (TDQ-60), a color picture-naming test for adults and the elderly into Turkish, establish its validity, and develop normative data adapted to the Turkish population to address this gap.
