ALVES, Lara; SIMOES, Mário R  and  MARTINS, Cristina. Premorbid intelligence measures in identifying cognitive decline. Aval. psicol. [online]. 2014, vol.13, n.1, pp. 29-36. ISSN 2175-3431 .

Cognitive decline assessment implies measuring discrepancies between the subject's previous (premorbid) and the current levels of functioning. However, this information is rarely available and clinicians have to infer it by using indirect methods. This article provides an historical overview of the different methods that have been developed for premorbid intelligence estimation, from the first qualitative methods to the most recent quantitative approaches. The discussion sustains that the most valid methods for premorbid intelligence estimation are those that combine current level of the subject's performance and demographic variables in regression formulas. The constant development of premorbid estimation methods with increasing validity is suggestive of the importance that this measure has for psychological assessment.

Keywords : premorbid intelligence; cognitive decline; neuropsychological assessment.
