Background: CHC theory is a hierarchical model of intelligence, organized through cognitive skills and dividing the construct into crystallized and fluid. Objective: To describe the correlation among crystallized and fluid abilities in healthy people diagnosed with dementia. Methods: 45 subjects with 50 to 89 years old and at least 1 year of schooling. They were submitted to a detailed clinical interview and, later, to a neuropsychological evaluation. RAVLT, Wechsler Intelligence Scale (WAIS-III or WASI) and FDT were applied. Sample was divided into 2 groups: healthy elderly (without cognitive and functional decline) and those diagnosed with dementia (GE). The diagnosis of dementia was based on the DSM-5. Results: RAVLT and the Wechsler Scale differentiated HE from DG (p <0.0001). FDT did not show a statistically significant difference in the Counting, Reading and Inhibition items, showing that tasks involve time were not able to differentiate healthy individuals from DG. To compare the performance IQ it is evident that the performance in fluid skills is less effective, when compared to the crystallized items (IQ verbal), in differentiating healthy subjects from dementia. Conclusion: Tasks involving learning, delayed recall memory and recognition, that is, crystallized tasks, are more effective in differentiating dementia when compared to fluid tasks (processing speed).
