Abstract
Alzheimer's disease (AD) is a serious neurodegenerative disease, which seriously affects the behavior, cognition, and memory of patients. Studies have shown that sensory stimulation can effectively improve the cognition and memory of AD patients, and its role in brain plasticity and neural regulation is initially revealed. This paper aims to review the effect of various sensory stimulation and multisensory stimulation for AD, and to explain the possible mechanism, so as to provide some new ideas for further research in this field. We searched the Web of Science and PubMed databases (from 2000 to October 27, 2020) for literature on the treatment of AD with sensory and multisensory stimulation, including music therapy, aromatherapy, rhythmic (e.g., visual or acoustic) stimulation, light therapy, multisensory stimulation, and virtual reality assisted therapy, then conducted a systematic analysis. Results show these sensory and multisensory stimulations can effectively ameliorate the pathology of AD, arouse memory, and improve cognition and behaviors. What's more, it can cause brain nerve oscillation, enhance brain plasticity, and regulate regional cerebral blood flow. Sensory and multisensory stimulation are very promising therapeutic methods, and they play an important role in the improvement and treatment of AD, but their potential mechanism and stimulation parameters need to be explored and improved.

Abstract
BACKGROUND Behavioral and psychological symptoms of dementia (BPSD) affect 60-90% of patients with Alzheimer's disease (AD). OBJECTIVE To determine if environmental therapy is an effective strategy to reduce BPSD, we tested 163 patients with AD with Neuropsychiatric Inventory (NPI) before and after 6 months of an indoor therapeutic garden (TG) or standard environment. METHODS A single-blind randomized controlled trial on AD patients with BPSD. Participants were randomized to an indoor TG (N = 82), or standard environment (control, N = 81) for 6 months. PRIMARY OUTCOME change in the NPI score from baseline (T0) to end of treatment (T1). SECONDARY OUTCOMES change in use of quetiapine, cognition, activities of daily living, salivary cortisol, blood pressure from T0 to T1. RESULTS NPI score significantly ameliorated (TG versus control: -31.8 points), quetiapine dosage (-150 mg), blood pressure (-2.6 mm Hg), and salivary cortisol (-6.4 to -2.1 Nmol/l) were significantly reduced, the Mini-Mental State Examination significantly improved (1.8 points) in the TG versus control arm at T1 (p < 0.001). No adverse events were reported. CONCLUSION The indoor TG seems safe and may reduce BPSD, medication intake, and cortisol levels in AD.

Abstract
Alzheimer’s disease (AD) provides a valuable field of research into impairment of self-consciousness (SC), because AD patients have a reduced capacity to understand their mental world, to experience and relive previous personal events, as well as to interpret thoughts, feelings, and beliefs about themselves. Several studies observed that AD patients had an altered SC, but not a complete abolition of it. Emotions are an integral part of the construction of personal identity, therefore of Self. In general, most studies on emotion in AD patients have observed that emotion is not completely abolished and it lets them better remember autobiographical events with greater emotional charge. The positive effect of autobiographical memories rich in emotional content, evoked directly/automatically by sensorial stimuli such as familiar odors or music, could be used to reestablish/reinforce the permanence and coherence of the Self in AD. We studied the research of empirical evidence supporting the power of the sensorial cues associated with emotion, which could be capable of enhancing the SC in AD. We presented the studies about “Emotional stimulations” using odor, music, or taste cues in AD. All studies have shown to have a positive impact on SC in AD patients such as odor-evoked autobiographical memories, taste/odor-evoked autobiographical memories, emotional sensorial stimulation using musical cues, and multi-sensorial stimulations using healing gardens. We found research supporting the notion that emotional sensorial stimulations can even temporarily exalt memory, affective state, and personal identity, that is, the SC in AD. The emotional sensory stimulations could be used as a tool to activate the SC in AD and hence improve the quality of life of patients and caregivers.

Abstract
Dementia is highly prevalent among the worldwide elderly population. Only a small number of the currently marketed drugs are effective in controlling its symptoms, and none has any effect on its progression. Further, as the condition advances, even these pharmaceuticals lose their efficiency, and new research into interventions that might improve the life quality of patients at the end stage of dementia and their families is increasingly rare. In our previous studies, we explored the benefits of exposure to nature, in the form of a Japanese garden, for persons with advanced dementia. In the current work, we extended our observations to two new locations and a new set of subjects with a different ethnic composition with the goal of identifying interventions that might improve their quality of life. We found that, even in these new settings, garden observation not only relieved physiological stress, it improved qualitative measures such as verbalization and memory retrieval. We present data that viewing the garden is a holistic experience rather a solely visual stimulus. Our new data further support the conclusion that garden observation is worth including in the care planning schedule of advanced dementia patients. Its low cost and easy availability make it an economical adjunct to current pharmacological methods that has the potential to improve the quality of life of people with dementia.
