ABSTRACTBackground: Individuals with dementia often experience poor quality of life (QOL) due to behavioral and psychological symptoms of dementia (BPSD). Music therapy can reduce BPSD, but most studies have focused on patients with mild to moderate dementia. We hypothesized that music intervention would have beneficial effects compared with a no-music control condition, and that interactive music intervention would have stronger effects than passive music intervention.Methods: Thirty-nine individuals with severe Alzheimer's disease were randomly and blindly assigned to two music intervention groups (passive or interactive) and a no-music Control group. Music intervention involved individualized music. Short-term effects were evaluated via emotional response and stress levels measured with the autonomic nerve index and the Faces Scale. Long-term effects were evaluated by BPSD changes using the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD) Rating Scale.Results: Passive and interactive music interventions caused short-term parasympathetic dominance. Interactive intervention caused the greatest improvement in emotional state. Greater long-term reduction in BPSD was observed following interactive intervention, compared with passive music intervention and a no-music control condition.Conclusion: Music intervention can reduce stress in individuals with severe dementia, with interactive interventions exhibiting the strongest beneficial effects. Since interactive music intervention can restore residual cognitive and emotional function, this approach may be useful for aiding severe dementia patients’ relationships with others and improving QOL. The registration number of the trial and the name of the trial registry are UMIN000008801 and “Examination of Effective Nursing Intervention for Music Therapy for Severe Dementia Elderly Person” respectively.

Short Term

in this study, we examined short and longer term effects of musical and cooking interventions on emotional well-being of severe Alzheimer's disease (AD) patients. These two pleasurable activities (i.e., listening to music, tasting sweets) that were collectively performed (i.e., playing music together, collaborative preparation of a cake) were compared in two groups of matched patients with AD (N = 14). Each intervention lasted four weeks (two sessions per week) and their effects were regularly assessed up to four weeks after the end of the intervention. We repeatedly evaluated the emotional state of both groups before, during, and after the intervention periods by analyzing discourse content and facial expressions from short filmed interviews as well as caregivers' judgments of mood. The results reveal short-term benefits of both music and cooking interventions on emotional state on all these measures, but long-term benefits were only evident after the music intervention. The present finding suggests that non-pharmacological approaches offer promising methods to improve the quality of life of patients with dementia and that music stimulation is particularly effective to produce long lasting effects on patients' emotional well-being.

Positive Results

In previous studies beneficial effects of peripheral electrical or tactile nerve stimulation were observed on memory and affective behaviour in patients with probable Alzheimer's disease. In the present study, it was investigated whether electrical and tactile stimulation applied simultaneously to Alzheimer patients would exceed the effects which were observed following treatment by each type of stimulation separately. Our data reveal that the simultaneous application of the two types of stimulation had a beneficial effect on non-verbal and verbal long-term recognition memory. In addition, patients who were treated participated more in activities of daily living, and were more interested in social contacts. In spite of these positive results, comparisons with those of previous studies suggest that a combination of electrical and tactile stimulation does not yield more effects than application of each type of stimulation separately.

Abstract Background Increased physical exercise improves cognitive function and reduces pathology associated with Alzheimer’s disease (AD). However, the mechanisms underlying the beneficial effects of exercise in AD on the level of specific brain cell types remain poorly investigated. The involvement of astrocytes in AD pathology is widely described, but their exact role in exercise-mediated neuroprotection warrant further investigation. Here, we investigated the effect of long-term voluntary physical exercise on the modulation of the astrocyte state. Methods Male 5xFAD mice and their wild-type littermates had free access to a running wheel from 1.5 to 7 months of age. A battery of behavioral tests was used to assess the effects of voluntary exercise on cognition and learning. Neuronal loss, impairment in neurogenesis, beta-amyloid (Aβ) deposition, and inflammation were evaluated using a variety of histological and biochemical measurements. Sophisticated morphological analyses were performed to delineate the specific involvement of astrocytes in exercise-induced neuroprotection in the 5xFAD mice. Results Long-term voluntary physical exercise reversed cognitive impairment in 7-month-old 5xFAD mice without affecting neurogenesis, neuronal loss, Aβ plaque deposition, or microglia activation. Exercise increased glial fibrillary acid protein (GFAP) immunoreactivity and the number of GFAP-positive astrocytes in 5xFAD hippocampi. GFAP-positive astrocytes in hippocampi of the exercised 5xFAD mice displayed increases in the numbers of primary branches and in the soma area. In general, astrocytes distant from Aβ plaques were smaller in size and possessed simplified processes in comparison to plaque-associated GFAP-positive astrocytes. Morphological alterations of GFAP-positive astrocytes occurred concomitantly with increased astrocytic brain-derived neurotrophic factor (BDNF) and restoration of postsynaptic protein PSD-95. Conclusions Voluntary physical exercise modulates the reactive astrocyte state, which could be linked via astrocytic BDNF and PSD-95 to improved cognition in 5xFAD hippocampi. The molecular pathways involved in this modulation could potentially be targeted for benefit against AD.

Model Of Alzheimer’S Disease

Alzheimer's disease (AD) is a common chronic neurodegenerative disease with well-defined pathophysiological mechanisms. Ilex kudingcha (IK) C.J. Tseng is commonly known as bitter tea or “Khom” tea in Vietnam. The present study was conducted to investigate the anti-dementia effect of IK using olfactory bulbectomized (OBX) mice. OBX mice were daily treated with IK extract (540 mg/kg) or reference drug, tacrine (2.5 mg/kg) 1 week before and continuously for 3 days after the OBX surgery. The object recognition test, modified Y maze test and fear conditioning test were employed to analyze non-spatial short-term, spatial short-term and long-term memories of the mice respectively. Administration of IK extract and tacrine attenuated these OBX-induced cognitive deficits in mice. The effects of IK and tacrine on spatial short-term memory impairment were reversed by scopolamine, a muscarinic receptor antagonist. The amyloid-beta (Aβ) production in adult transgenic Drosophila brain flies was also investigated by using Western blotting with APP-HA antibody. These results indicated that IK extract improves short-term and long-term memory disturbances in OBX mice and that muscarinic receptor may play a role on these actions. In addition, our result also showed that IK extract reduces the expression of amyloid precursor protein (APP) in brain of AD model using Drosophila melanogaster.
