BACKGROUND: The Addenbrooke’s Cogni've Examina'on III ACE-­‐III (2012) is a brief cogni've baTery that assesses various aspects of cogni'on. Its 5 subdomains (ATen'on and Orienta'on, Memory, Verbal Fluency, Language, and Visuospa'al Abili'es) are commonly impaired in demen'as. OBJECTIVES: To describe the qualita've process of selec'on, transla'on and cultural adapta'on of ACE-­‐III for use in the Egyp'an-­‐Arabic speaking popula'on. METHOD: First, the ques'onnaire was translated into Arabic, and then back-­‐translated into English. The process was then repeated un'l a consensus was reached about the op'mal transla'on. In addi'on, we modified the test to culturally adapt it to the Egyp'an popula'on. We modified the following parts of the ACE III: LeTer fluency, Name and address registra'on task, Knowledge memory task, Language repeon tasks, Picture naming and recogni'on, Reading, Recogni'on of camouflaged pictures. The modified ACE III was then piloted on 20 subjects with no complaint of cogni've impairment. RESULTS: Pilot subjects included 13 males and 7 female. The mean age of the subjects was 42.85 (SD=18.32) years. Performance on the culturally-­‐adopted items was as follows: on LeTer fluency subjects generated an average of 9.95 (SD=3.22) words per minute. Category fluency subjects generated an average of 31 (SD=15.7) words per minute. On comprehension, proverb repeon and reading fragmented leTers, the subjects made no errors. 85% (n=17) of the subjects made no errors on knowledge task. On word repeon, 95% (n=19) of the subjects made no errors. Of the 6 culturally-­‐adapted pictures for the Egyp'an popula'on, 100% (n=20) of the subjects were able to correctly iden'fy the lion, Aud (Lute), and Lamp; 95% (n=19) of the subjects were able to correctly iden'fy a giraffe; 90% (n=18) of the subjects were able to correctly iden'fy a parrot; and only 55% were able to correctly iden'fy a violin. CONCLUSION: Egyp'an Arabic m-­‐ACE III appears to be culturally equivalent aher all forms of biases or social norms specific to the culture of origin have been removed.

مصر ==ملخص البحث باللغة الاصلية== Introduction: The Addenbrooke’s Cognitive Examination III (ACE-III) (2012) is a brief cognitive battery that assesses various aspects of cognition. Its five subdomains (attention and orientation, memory, verbal fluency, language and visuospatial abilities) are commonly impaired in Alzheimer’s disease and frontotemporal dementia.

Objective: The aim of the study was to provide normative data for healthy adult performance on Egyptian–Arabic ACE-III.

Participants and methods: We adapted the ACE-III (2012) to the Egyptian population. We evaluated this version on 139 cognitively healthy volunteers aged 20 years or older (54.7% male and 45.3% female). We stratified the participants both by age (<60 years and >60 years) and by degree of education (basic, secondary or university education). None of the participants had any complaints of cognitive decline.

Results: We established normative data for healthy Egyptian adults below 60 years and above 60 years on each of the subdomains of the ACE-III. The data generated from the performance was assigned according to percentiles. We found a significant difference (P<0.001) between the performance of older and younger adults on the category task of the verbal fluency test.

Conclusion: By adapting the ACE-III to the Egyptian–Arabic population, we were able to establish normative data for healthy Egyptian adults.
