andard symptoms coupled with additional assessments that allow for the exclusion of other forms of dementia (Peterson, 2003). However, the disorder can be confirmed only by microscopic examination of a sample of brain tissue following death (Peterson, 2003).
It should be noted that ethnicity is involved even in diagnosis at the neurobiological level. In this regard, Glaser and associates (2004), in a study of the influence of the LRP1 promoter polymorphism c.1-25C>G on the human in vivo, found that results indicated that ethnic as well as genomic characteristics are involved in the determination of LRP1 expression. However, beyond this, culture can be of tremendous influence in the diagnosis of the condition. For example, if there are language problems mistakes can be made in assessments (Peterson, 2003).
Gauthier and Clarke (1999) report that ethnicity and culture are important variables to consider when diagnosing AD. This is especially important when considering that even with the same diagnostic instruments there are
