In many countries around the world, owing to the lack of specialists and equipment, delay up to a few years in help-seeking and getting diagnostic examinations for dementia is not uncommon (Sayegh and Knight, 2013), and this situation is considerably more serious in "atypical dementias" due to the challenge they present for differential diagnosis. For instance, a survey in the USA showed that misdiagnosis was common in patients with Lewy body dementia who, on average, saw at least three physicians over a year's time or more before getting the proper diagnosis (Lewy Body Dementia Association, 2010). Furthermore, in multiethnic communities, cultural and language barriers between practitioners and patients may lead to substantial delay as well (Sayegh and Knight, 2013).
