“…N2 latency may also be an effective method for assessment of tinnitus‐related cognitive ability, although only three CASI subdomains (“short‐term memory,” “orientation,” and “abstraction and judgment”) showed negative correlation with N2 latency. Taken together, the subdomains “short‐term memory” and “orientation” appeared to be the two most relevant subdomains as their combined score was shown to be more effective than the total score in assessing cognitive ability (Tsai et al., ). Meanwhile, the correlation analysis revealed that there was a negative relationship between each CASI subdomain score and THI score in the tinnitus experimental groups and the CASI score was also negatively correlated with THI score.…”

IntroductionSubjective chronic tinnitus is a common medical syndrome with a high frequency of cognitive impairment; however, the characteristics of cognitive impairment in chronic tinnitus are poorly understood. Investigating the scope of cognitive impairment across the severity spectrum of tinnitus patients may shed light on the issue.MethodsA consecutive series of 207 subjective chronic tinnitus patients were classified into mild tinnitus group (n = 95) and severe tinnitus group (n = 112) by THI score (the cutoff THI scores were 37/38). These patients were assessed using the Cognitive Abilities Screening Instrument (CASI) and P300 event‐related potential.ResultsAlthough pure tone averages were not different between mild or severe tinnitus patients, severe tinnitus patients scored lower on the CASI assessment as well as almost all subdomains of CASI, particularly in items such as “short‐term memory,” “concentration or mental manipulation,” “orientation,” “abstraction and judgment,” “language abilities,” and “visual construction.” Furthermore, compared to mild tinnitus patients, severe tinnitus patients exhibited longer N2 and P3 latencies. Finally, a correlation analysis revealed that tinnitus severity was negatively correlated with CASI score and positively correlated with N2 and P3 latencies.ConclusionsThis study reveals that tinnitus patients on the severe end of the spectrum may be at risk for serious cognitive deficits, which may not be a secondary response to disease manifestations but a primary feature of the underlying disease.

“…Its short f o rm (CASI-S) covers the ability to repeat (register) thre e w o rds and to recall them after an interval during which tests of temporal orientation and verbal fluency are perf o rmed. Recently, CASI-C eff e c t i v e n e s s in screening dementia has been improved by the use of an alternative scoring system (i.e., a weighted sum of the scores from the 9 cognitive domains) 5 . In this s t u d y, short -t e rm memory (delayed recall of 3 word s or 5 objects) and orientation appeared to be the two most relevant domains and their combined score was shown to be more effective than the total score in s c reening dementia.…”

-O b j e c t i v e:To determine CASI-S accuracy in the diagnosis of dementia. M e t h o d: The Cognitive Abilities Screening Instrument -Short Form (CASI-S) was applied in 43 Alzheimer's disease (AD) patients and 74 normal controls. AD diagnosis was based on DSM-IV, NINCDS-ADRDA, and CAMDEX. CASI-S includes: registration, temporal orientation, verbal fluency (4-legged animals in 30s), and recall (3 words). Its maximum score is 33 points. A copy of 2 pentagons was added. Results: ROC curve showed an accuracy of 0.87, with standard error of 0.032, and 95% confidence intervall between 0.795 and 0.925. The cut-off score for cognitive deficit was 23, with sensitivity of 76.7%, specificity 86.5%, positive likelihood ratio (LR) 5.68, and negative LR 0.27. The cut-off score for subjects 70 years or older was 20, with sensitivity of 71.4% and specificity 97.1%. C o n c l u s i o n: CASI-S is a practical test, with high specificity, particularly in individuals above 70 years of age. The adding of the drawing test did not improve its accuracy.

“…The AD patients have poorer performance in tests of episodic memory function and executive function, The results suggest that microstructural WM alterations in parietal, temporal, and frontal lobes may compromise the complex cognitive function involving multiple brain lobes, as also demonstrated by previous DTI studies. 49,50 Further explorations with other neuropsychological battery tests are encouraged to demonstrate the relationship between microstructural white matter changes and cognitive performance. We used CASI in this study, which provides a mini-comprehensive neuropsychological test for assessment of multiple domains (memory, executive function, visuospatial function, and language, etc.)…”

This study was designed to evaluate the microstructural integrity of white matter (WM) in amnestic mild cognitive impairment (MCI) and Alzheimer's disease (AD) among Han Chinese elderly using diffusion tensor imaging (DTI) technique, and to investigate the relationship between WM abnormalities and cognitive dysfunction. Sixty-four subjects (23 mild probable AD, 20 amnestic MCI, and 21 age-matched normal controls) who did not have visible WM lesion burden were analyzed. Fractional anisotropy (FA) and mean diffusivity were measured in normal-appearing WM (NAWM) using DTI with 64 encoding directions. The results were correlated with the scores of Mini-Mental State Examination (MMSE) and Cognitive Ability Screening Instrument (CASI). Statistical analysis showed the FA value in parietal WM was significantly lower in MCI compared to NC (P<0.001), and further decreased in AD compared to MCI (P=0.005). The lower FA and elevated mean diffusivity values were found in temporal WM, frontal WM, parahippocampal and posterior cingulate fibers of AD group compared to MCI and NC (all P<0.01). Canonical correlation analysis showed that the parietal FA values measured from all subjects were significantly correlated with the scores of CASI and MMSE (P<0.01). The results indicated that DTI can detect microstructural WM abnormalities in AD and amnestic MCI, and the measures were correlated with cognitive performance. In MCI, the abnormality was found to be limited within the parietal WM; and in AD a more widespread alteration was found in other brain regions as well.
