Introduction. Behavioral and psychological symptoms of dementia (BPSD) are defined as a group of symptoms of disturbed perceptive thought content, mood, or behavior that include agitation, depression, apathy, repetitive questioning, psychosis, aggression, sleep problems, and wandering. Care of patients with BPSD involves pharmacological and nonpharmacological interventions. We reviewed studies of nonpharmacological interventions published in the last 10 years. Methods. We performed a systematic review in Medline and Embase databases, in the last 10 years, until June 2015. Key words used were (1) non-pharmacological interventions, (2) behavioral symptoms, (3) psychological symptoms, and (4) dementia. Results. We included 20 studies published in this period. Among these studies, program activities were more frequent (five studies) and the symptoms more responsive to the interventions were agitation. Discussion. Studies are heterogeneous in many aspects, including size sample, intervention, and instruments of measures. Conclusion. Nonpharmacological interventions are able to provide positive results in reducing symptoms of BPSD. Most studies have shown that these interventions have important and significant efficacy.

Findings suggest that TAP-O may be an effective nonpharmacological strategy to reduce NPS of outpatients with dementia and to minimize caregiver burden.

INTRODUÇÃO: Com o envelhecimento, pode ocorrer um declínio cognitivo. Sabe-se que melhorar o desempenho das funções cognitivas em idosos tem consequências importantes em sua qualidade de vida. A literatura sugere que o treinamento pode aprimorar as funções cognitivas em idosos saudáveis. OBJETIVO: Verificar o efeito de grupo de estimulação cognitiva em idosos saudáveis. MÉTODOS: Estudo longitudinal no qual foram avaliados 32 participantes escolarizados, com idade acima de 60 anos, divididos em dois grupos. O grupo-caso participou de 10 sessões de estimulação cognitiva em grupo. O grupo-controle foi formado por 15 indivíduos, com idade e escolaridade similares. A amostra foi avaliada antes e após a intervenção, através de uma versão adaptada da bateria CERAD, teste do relógio e check-list de queixas cognitivas. Foi usada uma análise descritiva, bem como o teste t-pareado, com o intuito de observar as diferenças entre os grupos após a estimulação. RESULTADOS: Não houve diferenças entre os grupos quanto à idade, gênero e escolaridade. Na avaliação inicial, os grupos não apresentaram diferenças no desempenho dos testes aplicados. Na testagem após a intervenção, foi observada melhora apenas no grupo-caso nas tarefas de nomeação, fluência semântica, fluência total (bateria CERAD) e desenho do relógio, assim como na check-list de queixas cognitivas. CONCLUSÃO: A estimulação cognitiva realizada diminuiu as queixas cognitivas dos idosos participantes e melhorou seu desempenho em testes cognitivos.

Background: Neuropsychiatric symptoms (NPS) such as aggression, apathy, agitation, and wandering may occur in up to 90%of dementia cases. International guidelines have suggested that non-pharmacological interventions are as effective as pharmacological treatments, however without the side effects and risks of medications. An occupational therapy method, called Tailored Activity Program (TAP), was developed with the objective to treat NPS in the elderly with dementia and has been shown to be effective. Objective: Evaluate the efficacy of the TAP method (outpatient version) in the treatment of NPS in individuals with dementia and in the burden reduction of their caregivers. Methods: This is a randomized, double-blind, controlled clinical trial for the treatment of NPS in dementia. Outcome measures consisted of assessing the NPS of individuals with dementia, through the Neuropsychiatric Inventory-Clinician rating scale (NPI-C), and assessing the burden on their caregivers, using the Zarit Scale. All the participants were evaluated pre-and post-intervention. Results: 54 individuals with dementia and caregivers were allocated to the experimental (n = 28) and control (n = 26) groups. There was improvement of the following NPS in the experimental group: delusions, agitation, aggressiveness, depression, anxiety, euphoria, apathy, disinhibition, irritability, motor disturbance, and aberrant vocalization. No improvement was observed in hallucinations, sleep disturbances, and appetite disorders. The TAP method for outpatient settings was also clinically effective in reducing burden between caregivers of the experimental group. Conclusion: The use of personalized prescribed activities, coupled with the caregiver training, may be a clinically effective approach to reduce NPS and caregiver burden of individuals with dementia.
