Neuropsychological test performance of Spanish speakers: is performance different across different Spanish-speaking subgroups?

Even though theories and research have pointed out the importance of variables such as age, gender, or education on neuropsychological assessment, much less emphasis has been placed on language and culture. With the increasing population of Spanish speakers in North America and the limited amount of clinical and scholarly information currently available, neuropsychological assessment of this group has similarly become of increasing importance. Though several studies have been published over the last two decades, an assumption exists that all Spanish speakers, holding education and age constant, would perform similarly regardless of their origin.
