“…err: 0.088). One other study by Quinn et al (Adeloye et al , 2019) reported that IQCODE at cut-off of 3.3 had 80% sensitivity and 84% specificity in community dwelling older adult, and the Arabic adapted version of IQCODE (Phung et al , 2015) had sensitivity and specificity of 92.5% and 94.4% against DSM-IV criteria. Overall Hausa IQCODE has a good sensitivity and specificity and its values are comparable to those of some previous studies at the cut-off point of 3.2 but lower than what was reported for other versions of the instrument at a cut-off point of 3.3 (Phung et al , 2015; Harrison et al ,2015).…”

“…Hausa is a widely accepted language in northern Nigeria, and this language is spoken by an estimated 120 million people in the country, and in some other West and Northern African nations including Cameroon, Chad, Ghana, Benin, Togo, Ivory Coast and Sudan (Oyeyemi et al , 2011; Strahan and Bauer, 2007). Four studies reported on the prevalence of dementia in Nigeria citing a range of 0–10% (Ochayi and Thacher, 2006; Yusuf et al ,2011; Mavrodaris et al , 2013; Adeloye et al , 2019). Two of these studies (Ochayi and Thacher, 2006; Yusuf et al ,2011) reported a prevalence range 2.8% (Yusuf et al , 2011) and 6.4% (Ochayi and Thacher, 2006) among rural and city duelling Hausa speakers, respectfully.…”

Purpose This study aims at translating and adapting a common and widely used proxy rated cognitive screening tool – Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) into Hausa language and also to evaluate the instrument’s psychometric properties. Design/methodology/approach IQCODE was translated and adapted using a qualitative process involving experts and the adapted version was then evaluated against a gold standard (Diagnostic and Statistical Manual of Mental Disorder V criteria for neurocognitive disorders) with older adults subjects (N = 100), while its reliability (internal consistency) was also evaluated. Descriptive statistics of mean and frequencies, and inferential statistic of receiver operating curve analysis and Cronbach’s alpha coefficient were used for data analysis at an alpha level set at 0.05. Findings The Hausa IQCODE has a sensitivity value of 73.3%, specificity value of 71.8% and optimal cut-off values of between 3.2 and 3.3. For his adapted instrument the area under the Curve (AUC) curve is 0.79 (95% CI: 0.663–0.919; std. err: 0.066; P = 0.000), and Cronbach’s alpha value of 0.819 was obtained indicating that the adapted instrument has good internal consistency. Research limitations/implications The adapted IQCODE is a valid and reliable proxy based cognitive screening tool for the older adult Hausa speakers in Maiduguri. However, clinician and researcher might want to consider different optimal cut-off points when using this tool to screen or to monitor cognitive changes among older adults. Originality/value This research paper translated and adapted Hausa IQCODE into Hausa language. And it gives information on the validity and reliability of the adapted tool alongside with new optimal cut-off for cognitive screening by proxy among older adult patients in Nigeria.

Effect of Brain-Stimulating Games and Physical Activity on Cognitive Functions in Dementia in Calabar, Nigeria

Introduction: Dementia prevalence has increased in Nigeria in the last two decades, and its challenges have become more visible. Dementia is poorly understood in the population, so older individuals with symptoms of cognitive impairment are commonly branded 'insane' or 'possessed by evil spirits.' This has resulted in stigmatization, rejection, neglect, and abandonment of the affected. Emerging non-pharmacological treatment options like music, dance, brain games, and physical exercises are evidential for improving cognitive functions in older people with dementia. However, studies on such alternative procedures in dementia are scarce in Nigeria. This study determined the short-term effects of brain-stimulating games and physical activities on five cognitive functions in people with mild dementia in, Calabar, Nigeria.Methods: Mixed method design was used to collect data from 21 participants (13 older people with mild dementia and 8 caregivers). Participants with dementia were engaged in both brain-stimulating games and supervised physical activities for 12 weeks. Quantitative data were collected (pre-and post-intervention) using a validated 32-items tool which assessed 5 cognitive functions, and were analyzed on IBM-SPSS 20.0. Qualitative data were collected from caregivers through structured openended interviews, and thematic content analysis was done using NVivo 10. Results:Scores on all assessed cognitive functions showed that mentally stimulating games and physical activity interventions positively and significantly influenced cognitive functions in patients with mild dementia (p<0.05). Three themes emerged from qualitative data, and caregivers reported significant changes in mood, memory and attention span of the participants with dementia. Conclusion:A combination of mentally stimulating games and exercises improved cognitive functions in older people with mild dementia. Findings have both local and global implications for enhancing social engagement, self-esteem and wellbeing of people with dementia. Further studies should determine the effect of these interventions on people with severe dementia; and the effect of individual interventions (physical activity, or brain-stimulating games) on cognitive functions.

“…In Sub Saharan Africa, persons with dementia were 2.13 million in 2015 and are estimated to be 7.62 million by 2050 (Alzheimer Disease International, 2019). In Nigeria, the incidence of dementia has increased over the past two decades and currently has a prevalence of five percent among older adults aged 60 and above (Adeloye et al, 2019).…”

Dementia knowledge among physiotherapists in Nigeria

2022

Background With the growing population of older adults in Nigeria comes a simultaneous rise in the incidence of dementia in the country. Adequate knowledge of dementia is needed to effectively administer interventions for persons living with dementia. Physiotherapy is one of the professions providing care for people with dementia. The aim of this study was to evaluate the knowledge of dementia among physiotherapists in Nigeria. Methods An online survey method was used to collect data from the sample population of practicing physiotherapists in Nigeria. Data was collected using the 21-item Dementia Knowledge Assessment Tool Version Two (DKAT2) and the respondents also provided some demographic information. Mann Whitney test, Kruskal Wallis test and Spearman’s rho correlation were used to test for association between the DKAT2 scores and the demographic variables and this association was further explored with multiple linear regression analysis. Results A total number of 223 physiotherapists participated in this study. The findings of the study show that there is limited knowledge of dementia among the physiotherapists. Number of years of professional experience and specialty groups predicted significantly higher knowledge scores. Conclusion The knowledge deficits found among physiotherapists in Nigeria indicate that older adults living with dementia might not be receiving the best evidence-based physiotherapy treatments for their condition. This research therefore advocates for an educational intervention to be carried out within the physiotherapy profession in order to improve the quality of services rendered to their patients.
