Background: Agitation due to Alzheimer's disease (AD) presents a challenge to occupational therapists working in the older people care sector. Recently, background music and music therapy have emerged as promising tools in the management of agitation in AD. This exploratory study investigated whether live music could reduce agitated behaviour in people with AD. Method: A quasi-experimental one-group repeated measures design investigated the effect of a live, one-to-one, musical violin intervention on agitated behaviour in people with moderate-severe AD in a residential care facility. Seven participants received the musical intervention on three occasions. Participants were video recorded before, during and after each session. Behaviour was assessed by the investigator and a blinded assessor, using an investigator-modified Cohen-Mansfield Agitation Inventory. Thirty agitated behaviours were examined. Data were analysed using the Friedman test. Results: This intervention reduced agitated behaviour among participants. Significant reductions in pacing/aimless wandering (p = 0.023), performing repetitious mannerisms (p = 0.036) and general restlessness (p = 0.007) were observed. The total number of agitated behaviours decreased significantly (median 5 [range 2–8] behaviours before the intervention to 1 [range 0–4] during and 1 [range 0–5] after the intervention [p = 0.005]). Conclusion: Live music may be an effective strategy to reduce short-term agitated behaviour among people with AD.

Abstract The prevalence of negative representations of Alzheimer’s disease (AD) reinforces the stigma and negative attitudes toward this dementia. To mitigate these negative views, campaigns have been launched by several organizations. This study aims to explore the effect of framing in AD campaigns on attitude change. For this purpose, several posters were designed with framed messages defining dementia (dualism, unity, and control) and 189 participants were shown the posters. In order to analyze the effect of the different frames, a repeated-measures design was used, in which attitudes toward dementia were measured three times. The impact of the campaign and the emotions it produced were recorded as well as the effects of the participants’ experience with AD and the importance they attached to it. Posters with unity-framed messages produced a positive and lasting change in attitudes toward dementia and higher levels of happiness, while dualism-framed messages had a greater impact and produced feelings of sadness, anger, and fear but did not change the audience’s attitude. Although more research is needed on persuasion in campaigns, the findings can serve to guide the design of AD campaigns.

The revelation of adult brain exhibiting neurogenesis has established that the brain possesses great plasticity and that neurons could be spawned in the neurogenic zones where hippocampal adult neurogenesis attributes to learning and memory processes. With strong implications in brain functional homeostasis, aging and cognition, various aspects of adult neurogenesis reveal exuberant mechanistic associations thereby further aiding in facilitating the therapeutic approaches regarding the development of neurodegenerative processes in Alzheimer’s Disease (AD). Impaired neurogenesis has been significantly evident in AD with compromised hippocampal function and cognitive deficits. Melatonin the pineal indolamine augments neurogenesis and has been linked to AD development as its levels are compromised with disease progression. Here, in this review, we discuss and appraise the mechanisms via which melatonin regulates neurogenesis in pathophysiological conditions which would unravel the molecular basis in such conditions and its role in endogenous brain repair. Also, its components as key regulators of neural stem and progenitor cell proliferation and differentiation in the embryonic and adult brain would aid in accentuating the therapeutic implications of this indoleamine in line of prevention and treatment of AD.

: Alzheimer’s disease (AD) is a progressive brain disorder and one of the most common causes of dementia and death. AD can be of two types; early-onset and late-onset, where late-onset AD occurs sporadically while early-onset AD results from a mutation in any of the three genes that include amyloid precursor protein (APP), presenilin 1 (PSEN 1) and presenilin 2 (PSEN 2). Biologically, AD is defined by the presence of the distinct neuropathological profile that consists of the extracellular β-amyloid (Aβ) deposition in the form of diffuse neuritic plaques, intraneuronal neurofibrillary tangles (NFTs) and neuropil threads; in dystrophic neuritis, consisting of aggregated hyperphosphorylated tau protein. Elevated levels of (Aβ), total tau (t-tau) and phosphorylated tau (ptau) in cerebrospinal fluid (CSF) have become an important biomarker for the identification of this neurodegenerative disease. The aggregation of Aβ peptide derived from amyloid precursor protein initiates a series of events that involve inflammation, tau hyperphosphorylation and its deposition, in addition to synaptic dysfunction and neurodegeneration, ultimately resulting in dementia. The current review focuses on the role of proteomes in the pathogenesis of AD.

Lipids participate in Amyloid Precursor Protein (APP) trafficking and processing - important factors in the initiation of Alzheimer’s disease (AD) pathogenesis and influence the formation of neurotoxic β-amyloid (Aβ) peptides. An important risk factor, the presence of ApoE4 protein in AD brain cells binds the lipids to AD. In addition, lipid signaling pathways have a crucial role in the cellular homeostasis and depend on specific protein-lipid interactions. The current review focuses on pathological alterations of membrane lipids (cholesterol, glycerophospholipids, sphingolipids) and lipid metabolism in AD and provides insight in the current understanding of biological membranes, their lipid structures and functions, as well as their role as potential therapeutic targets. Novel methods for studying the membrane structure and lipid composition will be reviewed in a broad sense whereas the use of lipid biomarkers for early diagnosis of AD will be shortly summarized. Interactions of Aβ peptides with the cell membrane and different subcellular organelles are reviewed. Next, the details of the most important lipid signaling pathways, including the role of the plasma membrane as stress sensor and its therapeutic applications are given. 4-hydroxy-2-nonenal may play a special role in the initiation of the pathogenesis of AD and thus the “calpain-cathepsin hypothesis” of AD is highlighted. Finally, the most important lipid dietary factors and their possible use and efficacy in the prevention of AD are discussed.
