20.500.12556/DKUM-55182 UČINKI ANKSIOZNOSTI NA DELOVNI SPOMIN IN IZVRŠILNE FUNKCIJE PRI STAROSTNIKIH EFFECTS OF ANXIETY ON WORKING MEMORY AND EXECUTING FUNCTIONING IN ELDERLY Tema in namen: Tema in namen magistrske naloge je ugotoviti ali obstajajo učinki anksioznosti na delovni spomin in izvršilne funkcije pri starostnikih. Predvidevali smo, da bo anksioznost povezana z boljšimi kognitivnimi dosežki, kar bi se kazalo v korelacijah med izraženostjo anksioznosti in rezultati nevropsiholoških testov. Poleg tega je bil namen naloge preveriti tudi vpliv izobrazbe na kognitivne dosežke, pri čemer smo predvidevali, da bo dlje časa trajajoča izobrazba (ter posledično večja kognitivna rezerva) korelirala z boljšimi dosežki na testih. Želeli smo ugotoviti tudi, če med spoloma obstajajo razlike pri učinkih anksioznosti starostnikov na njihovo kognitivno delovanje. Na koncu smo želeli tudi preveriti, kateri simptomi anksioznosti so pri starostnikih najbolj izraženi, pri čemer smo predvidevali, da bodo najvišje izraženi simptomi somatične anksioznosti. Metodologija: Testiranih je bilo 50 starostnikov (19 M in 31 Ž), starih med 65 in 98 let. Vsi so izpolnili vprašalnik Geriatrična skala anksioznosti, s katerim smo preverili anksioznost. Po začetnem testiranju s presejalnim testom KPSS smo nevropsihološko testiranje nadaljevali s tistimi starostniki, ki so dosegli 19 točk in več. Vzorec je tako sestavljalo 42 testirancev (18 M in 24 Ž), starih med 65 in 98 let ter med 8 in 14 let trajajočo izobrazbo. Testiranje je zajemalo Stroopov barvo-besedni test, Ponavljanje števil naprej in nazaj ter TMT – podtesta A in B. Rezultati: Ugotovili smo, da na celotnem in moškem vzorcu anksioznost delno učinkuje na delovanje delovnega spomina (na fonološko zanko in centralnega izvršitelja) in izvršilnih funkcij (na preklapljanje setov), saj so se pokazale statistično pomembne korelacije pri testih ponavljanja števil naprej in nazaj ter TMT-B. Ostale korelacije niso bile statistično pomembne. Prav tako med kognitivnimi testi in trajanjem izobrazbe, razen pri testu ponavljanja števil naprej, statistično pomembnih korelacij ni bilo. To pomeni, da kognitivna rezerva, kot posledica daljše izobrazbe, v večini ne učinkuje na boljše kognitivno delovanje starostnikov. Ugotovili smo tudi, da večina starostnikov največ simptomov anksioznosti izraža na somatični podlestivici. Topic and goals: The topic and goals of the master's thesis were to determine whether effects of anxiety on working memory and executive functioning in elderly exist. We predicted that anxiety will be connected with cognitive performance, which would be reflected in correlations between the severity of anxiety and the scores on neuropsychological tests. Moreover, the goal of the thesis was also to examine the impact of education on cognitive performance. We predicted correlations between a longer education (and therefore a higher level of cognitive reserve) and better scores on tests. We also wanted to determine whether there are gender differences in the effects of anxiety in elderly on their cognitive functioning. Finally, we wanted to examine which anxiety sympthoms elderly exprience most. We predicted that somatic sympthoms will be the most pronounced. Methodology: We tested 50 elderly (19 M and 31 W), aged between 65 and 98 years. All of the participants completed Geriatric Anxiety Scale, which we used to test anxiety. After the initial testing with the screening test KPSS, we continued neuropsychological testing with those elderly, who achieved the score of 19 or more points. The sample then consisted of 42 participants (18 M and 24 W), aged between 65 and 98 years with 8 to 14 years of education. Testing included the Stroop test, Digit Span forward and backward and the TMT – parts A and B. Results: We established that the anxiety of the whole and men sample partially impacts functioning of the working memory (on phonological loop and central executive) and executive functions (on set-shifting) as results show statistically significant correlations on Digits span tests and TMT-B. Other correlations were not statistically significant. There also were no statistically significant correlations between cognitive tests and education duration, accept on Digit span forward. This means that the cognitive reserve, as a result of a longer education, mostly does not have an effect on better cognitive performance of the elderly. We also established that most elderly experience the most anxiety symptoms on the somatic subscale.
