It is also important to involve caregivers in the treatment, as they are part of the therapeutic triad: patient, family, and professionals. It is important to help caregivers to improve their relationship with the patient and to help them potentiate their current capacities. This can be achieved by using psychoeducation through training sessions to build the knowledge about the disease and the treatment (e.g., sharing the rationale of the intervention) and to improve the necessary skills in order to deal with the disease-related challenges (e.g., training the caregiver in responding to repetitive questioning without challenging the patient’s memory deficit). Moreover, interventions with caregivers should also address their expectations, specific needs, and emotional responses.

Cognitive and psychological interventions are becoming more recommended as treatments and clinical practice support their efficacy on BPSD. However, their apparent simplicity and accessibility contrast with the technical and methodological principles these techniques require. Furthermore, it is difficult to evaluate cognitive and psychological interventions’ effect by using the same principles of random control trials, since these complexes, sometimes multicomponent interventions, have to be patient tailored. In order to increase our confidence in these interventions, our beliefs that studies should look for more sensitive outcomes should be able to detect subtle changes in people’s daily living.

Finally, the importance of intensive and continuous staff training should be reinforced, especially in communication skills, in symptom assessment competencies, and in control of environmental triggers of psychological discomfort, in order to reduce the frequency of inadequate behaviors.
