The cognitive subscale of the Alzheimer’s Disease Assessment Scale is the most widely used test in the diagnostic and research work of Alzheimer’s disease. Aims: The aim of this study was to validate and investigate reliability of the Hungarian version of the Alzheimer’s Disease Assessment Scale in patients with Alzheimer’s disease and healthy control subjects. Methods: syxty-six patients with mild and moderate Alzheimer’s disease and 47 non-demented control subjects were recruited for the study. The cognitive status was established by the Hungarian version of the Alzheimer’s Disease Assessment Scale and Mini Mental State Examination. Discriminative validity, the relation between age and education and Alzheimer’s Disease Assessment Scale, and the sensitivity and specificity of the test were determined. Results: Both the Mini Mental State Examination and the Alzheimer’s Disease Assessment Scale had significant potential in differentiating between patients with mild and moderate stages of Alzheimer’s disease and control subjects. A very strong negative correlation was established between the scores of the Mini Mental State Examination and the Alzheimer’s Disease Assessment Scale in the Alzheimer’s disease group. The Alzheimer’s Disease Assessment Scale showed slightly negative relationship between education and cognitive performance, whereas a positive correlation between age and Alzheimer’s Disease Assessment Scale scores was detected only in the control group. According to the analysis of the ROC curve, the values of sensitivity and specificity of the Alzheimer’s Disease Assessment Scale were high. Conclusions: The Hungarian version of the Alzheimer’s Disease Assessment Scale was found to be highly reliable and valid and, therefore, the application of this scale can be recommended for the establishment of the clinical stage and follow-up of patients with Alzheimer’s disease. However, the current Hungarian version of the Alzheimer’s Disease Assessment Scale is not sufficient; the list of words and linguistic elements should be selected according to the Hungarian standard in the future.

Prevalent Form

Alzheimer’s disease (AD) is the most prevalent form of dementia, and age is strongly associated with the incidence of AD. This study aimed to investigate the association between the genotypes of CYP2D6, CYP3A4, and CYP2C9 genes to the clinical efficacy and tolerability of cholinesterase inhibitors (ChEIs) in Chinese patients with AD. One hundred seventy-nine patients with AD with newly prescribed with ChEIs were recruited. The clinical response and tolerability were evaluated at baseline, 3rd-, 6th-, and 12th-month follow-ups and were compared according to their genotypes of CYP2D6, CYP3A4, and CYP2C9. Among patients prescribed with donepezil/galantamine, CYP2D6*10 carriers showed significantly less side effects ( P = .009). CYP2D6*10 carriers responded better to ChEIs and resulted in better improvement in Alzheimer’s Disease Assessment Scale-Cognitive subscale ( P = .027) and Mini-Mental State Examination ( P = .012). Further study is required to replicate the finding, and it might be useful for clinicians to decide the medication based on the patients’ CYP genotypes.

Participantes: Pacientes con demencia asociada a cuerpos de Lewy y demencia de la enfermedad de Parkinson. Intervenciones: Las mediciones de eficacia en 33 pacientes con diagnóstico de DCL y DEP se realizó con el Mini-Mental State Examination (MMSE), Alzheimer Disease Assessment Scale cognitive subscale (ADAS-cog), Alzheimer’s Disease Cooperative Study-Clinical Global Impression of Change (ADCS-CGIC), Alzheimer’s Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL), Neuro-Psychiatry Inventory (NPI), Prueba de dibujo de Reloj de Manos (PDR-M) y la Unified Parkinson´s Disease Rating Scalemotor subscale (UPDRS-part III). Principales medidas de resultados: Síntomas cognitivos, funcionamiento global y actividades de vida diaria de los pacientes. Resultados: Diecisiete pacientes fueron tratados con rivastigmina, 9 con galantamina y 7 con donepezilo. Luego de 6 meses de tratamiento, los pacientes en tratamiento con rivastigmina mejoraron en 1,39 puntos en ADAS-cog respecto de su medición basal, mientras que los pacientes tratados con donepezilo y galantamina no mostraron cambios (cambios <0,2 puntos). Respecto al ADCS-ADL, los pacientes tratados con rivastigmina, donepezilo y galantamina demostraron disminución de 0,42, 0,58 y 0,75 puntos, respectivamente. En el MMSE, los pacientes tratados con rivastigmina y donepezilo no mostraron cambios y los pacientes tratados con galantamina tuvieron una disminución promedio de 1,19 puntos. No hubo diferencias significativas en la incidencia de síntomas parkinsonianos en los tres grupos de tratamiento. Los eventos adversos fueron similares en los tres grupos de tratamiento. Conclusiones: Los inhibidores de colinesterasa pueden ser benéficos en el manejo de síntomas cognitivos, el funcionamiento global y actividades de vida diaria en pacientes con demencia con cuerpos de Lewy y demencia de la enfermedad de Parkinson.

BackgroundThe Mini-Mental State Examination (MMSE), the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog) and the Severe Impairment Battery (SIB) are widely used rating scales to assess cognition in Alzheimer’s disease.ObjectiveTo understand the correspondence between these rating scales, we aimed to examine the linkage of MMSE with the ADAS-Cog and SIB total and change scores.MethodsWe used individual-level data on participants with Alzheimer’s disease (n=2925) from five pivotal clinical trials of donepezil. Data were collected at baseline and scheduled visits for up to 6 months. We used equipercentile linking to identify the correspondence between simultaneous measurements of MMSE with ADAS-Cog, and SIB total and change ratings.FindingsSpearman’s correlation coefficients were of strong magnitude between the MMSE total score and the ADAS-Cog (rs from −0.82 to −0.87; p<0.05) and SIB total scores (rs from 0.70 to 0.75; p<0.05). Weaker correlations between the change scores were observed between the MMSE change score and the ADAS-Cog (week 1: r=−0.11, p=0.18; rs thereafter: −0.28 to −0.45; p<0.05) and SIB change scores (rs from 0.31 to 0.44; p<0.05). Linking suggested that the MMSE total scores were sensitive to moderate and severe cognitive impairment levels. Despite weak to moderate correlations for the change scores, moderate change levels linked well, indicating ceiling and floor effects.ConclusionsThe current results can be used in meta-analyses, data harmonisation and may contribute to increasing statistical power when pooling data from multiple sources.Clinical implicationsThe current study results help clinicians to understand these cognitive rating scale scores.

Cognitive assessment in advanced stages of Alzheimer’s disease (AD) is limited by the imprecision of most instruments. Objective: To determine objective cognitive responses in moderate and severe AD patients by way of the Severe Mini-Mental State Examination (SMMSE), and to correlate performances with Mini-Mental State Examination (MMSE) scores. Method: Consecutive outpatients in moderate and severe stages of AD (Clinical Dementia Rating 2.0 or 3.0) were evaluated and compared according to MMSE and SMMSE scores. Results: Overall 400 patients were included, 67.5% females, mean age 76.6±6.7 years-old. There was no significant impact of age or gender over MMSE or SMMSE scores. Mean schooling was 4.4±2.5 years, impacting SMMSE scores (p=0.008). Scores on MMSE and SMMSE were significantly correlated (F-ratio=690.6325, p<0.0001). Conclusion: The SMMSE is influenced by schooling, but not by age or gender, and is an accurate test for assessment of moderate and severe AD.

Rater Error

The Alzheimer’s Disease Assessment Scale (ADAS-Cog) has become the de facto gold-standard for assessing the efficacy of putative anti-dementia treatments. There has been an increasing interest in providing greater standardization, automation, and administration consistency to the scale. Recently, electronic versions of the ADAS-Cog (eADAS-Cog) have been utilized in clinical trials and demonstrated significant reductions in frequency of rater error as compared to paper. In order to establish validity of the electronic version (eADAS-Cog), 20 subjects who had received a diagnosis of probable Alzheimer’s disease (AD) at a private US Memory Clinic completed a single-center, randomized, counterbalanced, prospective trial comparing a version of the eADAS-Cog to the standard paper scale. Interclass Correlation Coefficient on total scores and Kappa analysis on domain scores yielded high agreement (0.88 – 0.99). Effects of order and mode of administration on ADAS-Cog total scores did not demonstrate a significant main effect. Overall, this study establishes adequate concurrent validity between the ADAS-Cog and eADAS-Cog among an adult population with diagnosed AD.
