We review the increasing evidence, in humans and in mouse models, that show that there is often neuronal hyperactivity at early stages rather than decreased activity. We discuss studies in mouse models showing that hyperexcitability can occur long before plaque deposition and memory impairment. In mouse models, a generator of the hyperactivity appears to be the dentate gyrus. We present evidence, based on mouse models, that inhibition of muscarinic cholinergic receptors or medial septal cholinergic neurons can prevent hyperactivity. Therefore, we hypothesize the novel idea that cholinergic neurons are overly active early in the disease, not depressed. In particular we suggest the medial septal cholinergic neurons are overly active and contribute to hyperexcitability. We further hypothesize that the high activity of cholinergic neurons at early ages ultimately leads to their decline in function later in the disease. We review the effects of a prenatal diet that increases choline, the precursor to acetylcholine and modulator of many other functions. In mouse models of AD, maternal choline supplementation (MCS) reduces medial septal cholinergic pathology, amyloid accumulation and hyperexcitability, especially in the dentate gyrus, and improves cognition.</p>","PeriodicalId":520000,"journal":{"name":"Frontiers in dementia","volume":"4 ","pages":"1513144"},"PeriodicalIF":0.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12209278/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years there is an increased recognition of the importance and value of meaningfully including people with dementia in research, and of the epistemic injustice of systematic exclusion. While there are a growing number of research papers suggesting strategies for fostering ethical and meaningful inclusion, this area is still very much in development, theoretically and methodologically. This paper outlines how a theoretical perspective on selfhood in dementia, which incorporates the concept of the \"Intentional Stance\" (as per Sabat), may be a useful means of reaching people with dementia in a meaningful way via open, curious and personhood-supporting interactions. Embodying the \"intentional stance\" refers to operating under the assumption that all behavior and interactions do have meaning(s), even if it is not immediately or intuitively evident to the researcher what the meaning(s) are. Here, we draw on excerpts from an interview I conducted with a person living with dementia about his experiences of and perspectives on respite and day services, using the intentional stance, in conjunction with a range of other strategies for maximizing reciprocal communication. The analysis highlights instances where the intentional stance was central to connecting with the person, and temporarily entering their lifeworld. Adopting this stance is a means of reducing the epistemic injustice that people with dementia have faced, through longstanding omission and exclusion from research, and from social spheres more broadly.</p>","PeriodicalId":520000,"journal":{"name":"Frontiers in dementia","volume":"4 ","pages":"1596393"},"PeriodicalIF":0.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12176766/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
