“…As such, a LCA would try to identify each of the MCI subtypes through the scores obtained in the neuropsychological tests. Indeed, it is noteworthy that three subtypes of MCI were obtained when using an LCA (aMCI, naMCI, and mMCI) [ 94 ], corroborating the existence of three types of profiles with cognitive impairment among older participants not identified as being healthy.…”

As the conceptual, methodological, and technological advances applied to dementias have evolved the construct of mild cognitive impairment (MCI), one problem encountered has been its classification into subtypes. Here, we aim to revise the concept of MCI and its subtypes, addressing the problems of classification not only from the psychometric point of view or by using alternative methods, such as latent class analysis, but also considering the absence of normative data. In addition to the well-known influence of certain factors on cognitive function, such as educational level and cultural traits, recent studies highlight the relevance of other factors that may significantly affect the genesis and evolution of MCI: subjective memory complaints, loneliness, social isolation, etc. The present work will contemplate the most relevant attempts to clarify the issue of MCI categorization and classification, combining our own data with that from recent studies which suggest the role of relevant psychosocial factors in MCI.

“…HKB olgularının sağlıklılardan ve demans hastalarının da HKB olgularından ayrımında nöropsikolojik testler en geçerli araçlardan biri olarak kabul edilmektedir 10 . HKB olgularının, nöropsikolojik testlerin bir veya daha fazlasında sağlıklılara oranla ortalamanın 1.5 standart sapma (SS) altında performans gösterdikleri gösterilmiştir 11,12 . Klinik pratikte bilişsel işlevleri değerlendirmek için her ne kadar kapsamlı nöropsikolojik değerlendirme yapmak önemli olsa da, hızlı taramalarla fikir edinebilmek gündelik koşullarda çok önemlidir.…”

Demans tarama ve tanısı için klinik pratikte sıklıkla kısa tarama testleri kullanılmaktadır. Mini Mental Durum Testi (MMDT) en sık kullanılan testlerin başında gelmektedir. MMDT’nin demans için duyarlı olduğu bilinmektedir. Ancak, sağlıklı yaşlanma ile demans arasında bir geçiş evresi olarak kabul edilen Hafif Kognitif Bozukluk (HKB)’un ayırt edilmesinde ve Alzheimer Hastalığı tipi demans (AHD) ile HKB’nin ayırıcı tanısında MMDT çoğu zaman yeterli olmamaktadır. Kısa sürede uygulanabilen sözel akıcılık testleri (semantik ve fonemik) MMDT’ye alternatif ya da MMDT ile kullanıldığında HKB ve AH’nin erken evreleri için tanısal doğruluğu daha yüksek bir tarama testi elde edilebilir. Bu çalışmanın amacı MMDT, semantik ve fonemik akıcılık testlerinin ROC eğrisi analizleri ile belirlenen duyarlılık, özgüllük ve kesme puanı değerlerinin sunulmasıdır. Çalışmaya yaş-eğitim-cinsiyet açısından uyumlu 72 sağlıklı birey, 72 HKB ve 72 AHD’li birey dahil edilmiştir. Çalışmanın bulguları MMDT’nin sağlıklı bireyleri ayırt etmede semantik ve fonemik akıcılıktan daha güçlü olduğunu, ancak HKB ve AH ayrımında özgüllüğünün semantik akıcılıktan düşük olduğunu göstermektedir. Tanı doğruluğunun artırılması için kısa zamanda uygulanabilen sözel akıcılık testlerinin, özellikle semantik akıcılık testinin klinik pratiğe eklenmesi yararlı olabilir.

“…Finally, in the Diagnostic and Statistical Manual of Mental Disorders (DSM) of the American Psychiatric Association (APA), in its fifth edition, the term MCI has been included as a minor neurocognitive disorder and includes, among its diagnostic criteria, that the individual must make more effort, use compensatory strategies, or make an accommodation to maintain independence in IADLs [14,15]. In any case, there is a consensus in considering the results of cognitive tests as diagnostic criteria for people with MCI [16,17], whereby psychometric data play an important role in comparing the results of cognitive tests with the normative data of the reference population [18].…”

Difficulty in performing instrumental activities of daily living (IADLs) is currently considered an important indicator of cognitive impairment in the elderly. A non-experimental case–control investigation was conducted to assess the convergent validity of the PA-IADL with traditional (standard) cognitive assessment tests in its ability to identify adults with mild cognitive impairment. The analysis of the data was carried out by means of various multivariate statistical tests, and the sequence in its execution led to the conclusion that 8 of the 12 Tasks that make up the PA-IADL allow for the identification of people with mild cognitive impairment (MCI) to the same extent as traditional cognitive assessment tests and regardless of age. Age was found to be a moderating variable in the performance of the eight tasks; however, the results allow us to hypothesize that people with MCI experience a significant decline when it happens but thereafter, the deterioration that occurs does so at the same rate as the deterioration experienced by healthy people. They also allow us to hypothesize that the difference in the cognitive skills required by the eight functional tasks, and therefore also in the cognitive skills required by the traditional (standard) tests of a person with MCI compared to a person of the same age without MCI (Healthy), is approximately 10 years. These hypotheses have remarkable relevance and should be tested via longitudinal research. In the meantime, the results highlight the importance of the IADL assessment for the diagnosis of MCI as a complement to the standard cognitive assessment.
