RESUMO
INTRODUCTION: Dubois' five words testing (5WT) is a verbal memory test that depends on many parameters. The aim of this study is to adapt Dubois' 5WT to the Malian socio-cultural conditions to (i) determine performances of normal subjects to the 5WT and (ii) provide reference scores of the 5WT. METHODS: A sample of 276 normal subjects aged ≥ 50 years (154 males and 122 females; 144 literates and 132 illiterates) were enrolled from February 2008 to January 2009. Subjects with a history of symptoms likely to modify cognitive functions and those who were found disabled under Lawton's four simplified item test were excluded. RESULTS: The learning score in illiterates was 1.51 in Dubois' 5WT and 4.90 in the modified 5WT. The mean value of the modified 5WT total score was 9.71. Majority (90.22%) of the subjects scored the maximum (10). The modified 5WT reduced with both the age (p < 0.006) and education level (p < 0.04). CONCLUSION: Our results show that Dubois' 5WT is influenced by culture and the socio-educative level in French. Its adaptation to the socio-cultural context could prove useful and efficient in countries with a low literacy rate and a diverse cultural background.
RESUMO
INTRODUCTION: Despite significant progress in the field of scientific research on Parkinson's disease (PD), the prevalence and pathophysiology of its non-motor signs remains less understood than the classic motor signs of bradykinesia, rigidity, tremor and postural instability. Data covering this topic are rare in Africa, and almost non-existent in sub-Saharan Africa. Thus, this study aims to highlight the frequency of certain non-motor signs in PD patients followed in the Department of Neurology of the University Hospital Point "G", Bamako, Mali. METHODOLOGY: This is a retrospective and descriptive study from January 2012 to November 2013. We identified records of patients with dopamine-responsive idiopathic Parkinson's disease, and quantified associated non-motor symptoms. Data were analyzed with Epi-Info 2000 version 3.5.5. RESULT: During this period we reviewed 60 patient charts of which 68.3% were men. The average age of patients was 66.51 ranging from 25 to 94 years.Non-motor symptoms were present in 90% of cases, including sensitive disorders in 76.7%, dysautonomia in 73.3%, and psycho-behavioral disorders, including sleep disorders, in 81.7%. CONCLUSION: At the end of this study, we observed an important place for non-motor signs in the clinical manifestation of PD patients in general.
