Experimental Study to Validate the "Therapeutic Game" CONEM-BETA

• change from baseline compared to the control and active arms using the Cornell scale and NPI-Q to assess behaviour of the patients with probable or possible Alzheimer's disease or other advanced stage dementia [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  Cornell scale assesses the signs associated with depressive disorders in patients with dementia. It contains 19 items that assess 5 dimensions of depression: changes in mood, behavior disorders, physical signs, circadian rhythms, and judgement disorders. NPI-Q is based on NPI (Neuropsychiatric Inventory), and was designed as screening tool to assess the emotional distress of the caregiver. NPI-Q assesses the degree of delusions, hallucinations, agitation, depression, anxiety, euphoria, apathy, disinhibition and irritability.
• change from baseline compared to the control and active arms using the Martin and cols. scale to assess the overload level of the family caregivers of patients with probable or possible Alzheimer's disease or other advanced stage dementia [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  Martin and cols. scale is an adaptation of the Zarit questionnaire to assess the overload level of the caregiver. It is a self administered questionnaire, with 22 items.
• change from baseline compared to the control and active arms using the Goldberg's scale to assess anxiety and depression of the family caregivers of patients with probable or possible Alzheimer's disease or other advanced stage dementia [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  The Goldberg's questionnaire has two subscales with 9 items each, one for anxiety and one for depression. It was originally designed by Goldberg with the aim of having a short interview as a screening tool.
• change from baseline compared to the control and active arms using the DUKE-UNC scale to assess the perceived social support of the family caregivers of patients with probable or possible Alzheimer's disease or other advanced stage dementia [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  Developed for the general population, the DUKE-UNC questionnaire allows to assess the perceived social support. It is self-administered and contains 11 items.
• change from baseline compared to the control and active arms using the PANAS scale to assess the changes in positive and negative affect of the caregivers of patients with probable or possible Alzheimer's disease or other advanced stage dementia [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  The PANAS questionnaire includes 20 items, 10 related to the impact on positive affect (PA), and 10 related to the negative impact in affect (NA).

The purpose of the study is to assess the efficacy of the systematic application of the CONEM-BETA game in the subjective welfare of family caregivers of patients with Alzheimer's disease or other advanced stage dementia.

Alzheimer's disease (AD) is clinically diagnosed based on memory and cognitive deterioration, and the loss of other functional abilities. Nevertheless, for the caregivers and the patients themselves, the psychological and behavioral symptoms of dementia (PBSD) are specially relevant aspects.

These PBSD are a source of stress for the caregiver. PBSD treatment starts with non-pharmacological treatment, but if the symptomatology is moderate to severe, then pharmacological treatments are indicated on top of the non-pharmacological ones. The symptoms that better respond to non-pharmacological interventions are depression and mild apathy, wanderings and repetitive behaviors.

Once dementia progresses, the ability to interact at cognitive and emotional levels are reduced, and then, alternative approaches are needed. In this circumstance, it has been postulated that the caregivers should not try to bring -patients with AD back to the objective reality, but that they should rather empathize with them and establish an emotional connection. This is a complex process, and requires intervention tools that favor this connection and improve the subjective welfare of the caregivers of persons with dementia.

The current study is based on a previous experience in implementing the Montessori method at SARquavitae nursing homes and daycare centers. The "therapeutic game" called CONEM-BETA contains a subset of these activities that have been adapted from the original texts from the Myers Research Institute. We aim to prove that CONEM-BETA may have also socio-emotional benefits for the caregivers when they systematically use them at home with their AD relatives. These potential benefits will be assessed by using validated questionnaires that measure changes in subjective welfare, anxiety and depression, coping strategy, overload level and perceived social support.

• Alzheimer's Disease
• Dementia

• Other: CONEM-BETA + socio-educational training
  4 socio-educative training sessions during 8 weeks, and caregivers will systematically play with their patients with CONEM-BETA therapeutic game during the last 4 weeks. The dyads will be assessed (primary timepoint). Caregivers will then continue using the game with their patients for an extra 6 weeks period as needed, to assess adherence and games preferences.
• Other: Socio-educational training only
  4 socio-educative training sessions during 8 weeks

• Experimental: CONEM-BETA + socio-educational training

  Caregivers will receive 4 socioeducational training sessions during an 8 week period. These sessions will focus on the description and process of the Alzheimer's disease (AD), and will also provide to the caregivers resources and strategies to cope with AD. During the last 4 weeks, they will also systematically play with the patient at home with the CONEM-BETA game.

  After that period, caregivers will use the game based on their preference and frequence during a period of 6 more weeks.

  Intervention: Other: CONEM-BETA + socio-educational training
• Active Comparator: Socio-educational training only
  Caregivers will receive the same 4 socioeducational training sessions as the experimental group, during an 8 week period.
  Intervention: Other: Socio-educational training only
• No Intervention: Control
  Caregivers of this group will behave with his/her patient during the trial as they have been doing so far, but will receive no intervention
