This trials of cognitive stimulation therapy (CST) in Tanzania is part of the larger Identification and Intervention for Dementia in Elderly Africans (IDEA) study.
The overall aim of the IDEA study is to set up and evaluate sustainable programmes to facilitate diagnosis of, and therapy for, people with dementia led by local communities in sub-Saharan Africa. We aim seek to improve quality of life for people with dementia and their caregivers.
Within this trial of CST, we hypothesise that CST can significantly improve the quality of people with dementia and their carers living in Africa
Our project will address three specific challenges: 1) Integrate screening and core packages of services into routine primary health care. 2) Provide effective and affordable community-based care and rehabilitation. 3) Develop effective treatment for use by non-specialists, including lay healthcare workers with minimal training.
Dementia is under-diagnosed in sub-Saharan Africa (SSA) and treatment is rarely accessed or available. The burden of dementia on caregivers is high, with loss of income, and psychosocial stress common. However, large scale screening for dementia in such a setting is neither affordable nor sustainable. The purpose of this 3 year project is to provide a sustainable mechanism for diagnosis and therapeutic intervention for people with dementia. We will use 2 complimentary, rural study sites, 1 in Nigeria, West Africa and 2 in Tanzania, East Africa. As a consequence our results should be generalizable to all SSA. Our approach is inexpensive and will have applicability to other low- and middle-income countries.
During Phase I we will validate a screening tool, previously developed by members of our study team from data collected in Tanzania, and carry out a pilot study of the benefits of cognitive stimulation therapy (CST) when used in SSA for those already identified with dementia. During both of these activities we will initiate training of local healthcare workers in diagnosis and management of people with dementia. In Phase II we will engage with local communities to raise awareness of dementia. Building on previous work at both study sites, we will initiate poster, newspaper and radio advertising and use mobile phone text messaging services (for relevant healthcare personnel) to increase awareness of the need to diagnose and intervene at an early stage. We will empower local private pharmacies to help identify people with dementia, a relationship which will ultimately be mutually beneficial through the supply of medicines to treat risk factors for dementia, such as hypertension. We will engage with local community leaders and government officials to assist us in this awareness raising, an approach that has proven successful in previous studies by our team in SSA. One of our study team (Dr Mushi (DM)) is a social scientist based in Tanzania and during Phase II we will conduct qualitative research into attitudes and beliefs surrounding dementia and identify any barriers to diagnosis in both sites. The results of this research will be fed back to inform other phases of the study. Finally, in phase III we will initiate a program of community based CST led by local occupational therapists (OTs) and nurse specialists. OTs and nurses will train caregivers in CST techniques and we hope that the training will ultimately be led by caregivers allowing such therapy to become sustainable within communities in the longer term. We will evaluate changes in cognition in people with dementia, and quality of life (QOL) in both people with dementia and their caregivers, post-intervention. We will carry out a full economic evaluation of the effect of our program, to be led by a heath economist based at Newcastle University, United Kingdom.
This protocol cover the CST trial (Phase III of the study) in Tanzania

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CST intervention | Experimental | We will use a two-group stepped-wedge design. Group 1 will receive the intervention immediately. This will also allow group 2 to act as controls for group 1 and allow further analysis as a controlled trial, during secondary analysis. In accordance with the CST manual protocol, patients will be allocated to groups to ensure a spread of abilities and ensure inclusivity. No group contains only one individual of a particular religion or gender, such that they may feel left out. We will allocate patients to groups to avoid excessive travel to the group meeting place, participants may be allocated to a group based on their geographical location. |
|
| Group 2 | No Intervention | and group 2 will have their intervention delayed until after the end of the group 1 intervention. This will also allow group 2 to act as controls for group 1 and allow further analysis as a controlled trial, during secondary analysis. |

| CST Intervention | Behavioral | The CST intervention comprises 14 sessions lasting 1-2 hours across 7 weeks. The CST manual has been adapted for use in this setting by members of our study team. Each session has a theme. Activities include tasks aimed at engaging participants in cognitive and physical tasks designed to improve quality of life. Sessions will be led and facilitated by a study nurse or occupational therapist. The sessions will be held at a local health centre of village hall. |
