Background: Neurological disorders are the leading cause of disability, affecting over three billion people worldwide. Amyotrophic lateral sclerosis (ALS) is among the most feared and uniformly fatal neurodegenerative diseases, with no therapy capable of restoring lost function. Methods: We report the first application of therapeutic fever to ALS using Computerized Brain-Guided Intelligent Thermofebrile Therapy (CBIT²). This fully noninvasive treatment, delivered through an FDA-approved computerized platform, digitally reengineers the 1927 Nobel Prize-recognized malarial fever therapy into a modern treatment guided by the Brain–Eyelid Thermoregulatory Tunnel. CBIT² induces therapeutic fever through synchronized hypothalamic feedback, activating heat shock proteins, which are known to restore proteostasis and neuronal function. Case presentation: A 56-year-old woman was diagnosed with progressive ALS at the Mayo Clinic, with electromyography (EMG) demonstrating fibrillation and fasciculation indicative of denervation corroborated by neurological and MRI findings; the patient was informed that she had an expected survival of three to five years. A neurologist from Northwestern University confirmed the diagnosis and thus maintained the patient on FDA-approved ALS drugs (riluzole and edaravone). Her condition rapidly worsened despite pharmacological treatment, and she underwent CBIT², resulting in (i) electrophysiological reversal with complete disappearance of denervation; (ii) biomarker correction, including reductions in neurofilament and homocysteine, IL-10 normalization (previously linked to mortality), and robust HSP70 induction; (iii) restoration of gait, swallowing, respiration, speech, and cognition; (iv) reconstitution of tongue structure; and (v) return to complex motor tasks, including golf, pickleball, and swimming. Discussion: This case provides the first documented evidence that ALS can be reversed through digitally reengineered fever therapy aligned with thermoregulation, which induces heat shock response and upregulates heat shock proteins, resulting in the patient no longer meeting diagnostic criteria for ALS and discontinuation of ALS-specific medications. Beyond ALS, shared protein-misfolding pathology suggests that CBIT² may extend to Alzheimer’s, Parkinson’s, and related disorders. By modernizing this Nobel Prize-recognized therapeutic principle with computerized precision, CBIT² establishes a framework for large-scale clinical trials. A century after fever therapy restored lost brain function and so decisively reversed dementia paralytica such that it earned the 1927 Nobel Prize in Medicine, CBIT² now safely harnesses the therapeutic power of fever through noninvasive, intelligent, brain-guided thermal modulation. Amid a global brain health crisis, fever-based therapies may offer a path to preserve thought, memory, movement, and independence for the more than one-third of humanity currently affected by neurological disorders.

Alzheimer’s disease (AD) is a complex pathological process that incurs significant societal costs, yet effective treatments have not yet been developed. Novel compounds targeting β-amyloid, based on the amyloid cascade hypothesis, have failed to demonstrate clinical efficacy. Among natural products with diverse mechanisms, components contained in Astragali radix have shown anti-dementia effects in various preclinical studies, including improved cognitive function, reduced β-amyloid levels, and decreased insulin resistance. This study administered a water-extracted roasted Astragali radix (RA) to 3-month-old female 5xFAD mice for 3 months, observing changes in cognitive behavior, blood glucose, and neural signaling. RA lowered glucose levels, improved working memory, fear avoidance memory, and spatial memory, and reduced anxiety behavior in 5xFAD mice. In the hippocampus, the protein expression of BDNF and p-CREB/CREB was increased, while p-JNK/JNK was decreased. The effects of RA were similar to unroasted Astragali radix in 5xFAD mice, with some components being more abundant. Therefore, RA enhances its taste and aroma, making it suitable for long-term consumption in the form of tea, which could be effective in preventing neurodegenerative diseases such as dementia.

As a metabolism-controlling peptide, insulin affects activity of almost all tissues in human organisms, including the ones located in the central nervous system. By modifying glucose uptake and processing, as well as inducing anabolic effects, insulin alters functions of various nerve centers. Data from numerous clinical trials prove that such actions can have positive influence on cognitive processes or might be utilized as measures to control appetite, mood, and blood flow, or to prevent unfavorable mental states associated with diminished ability to maintain homeostasis. The intranasal route of administration provides an efficient and targeted delivery method, allowing insulin to be applied directly to different brain regions via the nasal mucosa. Such an approach can also reduce the risk of potential adverse effects associated with this medication, including drops in plasma glucose levels. This review gathers clinical studies’ findings on intranasal insulin’s neuromodulatory properties and its efficacy as additional treatment measure in several neuropsychiatric disease entities.

Currently, approximately 40% of patients with dementia develop some form of sleep disorder. Benzodiazepines are widely prescribed but pose the risk of tolerance and cognitive decline; however, Z-drugs may offer safer alternatives. Therefore, this systematic review aimed to analyze the effect of benzodiazepines and Z-drugs on sleep disorders in patients with dementia. Two authors conducted a systematic search in PubMed, Scopus, Web of Science, Espistemonikos, and ACCESSSS for studies published between 2019 and 2024 using the MeSH terms “dementia”, “sleep disorders”, and “pharmacotherapy”. Randomized clinical trials comparing benzodiazepines, Z-drugs, or innovative medications with placebo or other drugs were included. Sleep and cognitive outcomes were assessed using validated instruments; the ROB-2 tool evaluated the risk of bias. The protocol was registered in “PROSPERO”. Three randomized clinical trials involving a total of 192 patients were included in the review. Zopiclone increased the main duration of nighttime sleep by 81 min, Zolpidem reduced nighttime awakenings by 21 min, and Eszopiclone improved sleep quality, benefited the progression of sleep architecture, and reduced mental symptoms such as fear and anxiety. Z-drugs show superior efficacy and safety over benzodiazepines, improving sleep and cognitive symptoms in dementia. Personalized treatment and further research across dementia subtypes are needed to optimize long-term outcomes. Full article

Background/Objectives: As the world’s population ages, the growing number of individuals affected by Alzheimer’s disease and related dementias (ADRDs) will undoubtedly continue to impose social and economic challenges. Informal caregivers play a crucial role in providing essential support for individuals with ADRD. However, there is limited research that investigates the psychosocial functioning of caregivers (partners) from minoritized groups. Methods: This study aimed to explore the experiences of lesbian, gay, bisexual, transgender and queer (LGBTQ+) caregivers of individuals with ADRDs. Semi-structured in-depth interviews were conducted with seven caregivers of partners diagnosed with ADRDs. Three themes were identified based on reflexive thematic analysis: (i) experiencing familial alienation; (ii) fear about the future; and (iii) finding strength in the face of adversity. Results: The research highlighted difficulties reported by LGBTQ+ caregivers, while also showing how such caregivers cope. The findings provide a basis for developing targeted interventions for caregivers from minoritized groups. Conclusions: These findings have important implications for policy and intervention development concerning LGBTQ+ caregivers’ mental and physical health outcomes. Full article

Aim: Our aim was to survey people with dementia and their carers with respect to their propensity to join a randomized trial of community singing in dementia, in the context of uncertainty following the COVID-19 pandemic. Method: We employed an online anonymous questionnaire, comparing activities before and after lockdown, worries about COVID-19, whether people would attend a singing group and what measures might make this more likely. With a target sample of 100, the survey was distributed to the general population of people with dementia and carers in the UK between June and August 2022. Results: We had a total of 168 respondents, of whom 30% were people living with dementia and 70% were carers. Those who were not worried (roughly 62%) were more likely to go out to groups. Worries about COVID-19 affected 38% of respondents but some judged the risk of going out to be worthwhile. Most felt able to take adequate precautions against infection. However, COVID-19 transmission was not the main impediment to attending a singing group and 19% of respondents were simply not interested in doing so, while mobility and shyness deterred others. Conclusions: Given recruitment problems, quantitative studies of singing in dementia need to take account of individual preferences as well as contextual barriers, including fear of virus transmission, individual perceptions of the intervention and logistical obstacles to participation.

Background: The fimbria-fornix is a nerve fiber bundle that connects various structures of the limbic system in the brain and plays a key role in cognition. It has become a major target of deep brain stimulation (DBS) to treat memory impairment in both dementia patients and animal models of neurological diseases. Previously, we have reported the beneficial memory effects of chronic forniceal DBS in mouse models of intellectual disability disorders. In Rett syndrome and CDKL5 deficiency disorder models, DBS strengthens hippocampal synaptic plasticity, reduces dentate inhibitory transmission or increases adult hippocampal neurogenesis that aids memory. However, the underlying neuronal circuitry mechanisms remain unknown. This study we explored the neural network circuits involved in forniceal DBS treatment. Methods: We used acute forniceal DBS-induced expression of c-Fos, an activity-dependent neuronal marker, to map the brain structures functionally connected to the fornix. We also evaluated the mouse behavior of locomotion, anxiety, and fear memory after acute forniceal DBS treatment. Results: Acute forniceal DBS induces robust activation of multiple structures in the limbic system. DBS-induced neuronal activation extends beyond hippocampal formation and includes brain structures not directly innervated by the fornix. Conclusions: Acute forniceal DBS activates multiple limbic structures associated with emotion and memory. The neural circuits revealed here help elucidate the neural network effect and pave the way for further research on the mechanism by which forniceal DBS induces benefits on cognitive impairments.

Individuals, families, and communities are impacted by Alzheimer’s disease and other dementias worldwide. In Canada and elsewhere, family members commonly see loved ones living with dementia experience difficult moments, including anxiety, stress, and fear. Struggling health care systems strive to apply the latest evidence-based interventions. In this case report, we explore how individuals who care for people with dementia can help redirect difficult personal and interpersonal moments towards hopeful moments in the presence of therapy dogs. The cases of four individuals diagnosed with dementia and interacting with therapy dog intervention in one of three environments—at a family home, in a hospital awaiting placement to a long-term care facility, and in a psychiatric centre—are reviewed from the perspectives of two attending therapy dog handlers. In addition to being researchers in the therapy dog field and authors on this case report, both handlers were guided in a 110 min focused conversational method by a third author, from which self-affirmation theory surfaced as a guiding framework for explaining their observations and experiences. Therapy dog visiting appears to facilitate positive social interactions that can help redirect difficult moments to moments defined by self-affirmation or experiencing a positive sense of self. This is an under-recognized association in the dementia literature. Self-affirmation is demonstrated through four themes during therapy dog visits: (a) physical movement, (b) psychological shift, (c) a transition in the experience of time, and (d) connective interactions. Therapy dogs are identified here as a promising self-affirming psychosocial intervention for individuals with dementia and their caregivers worthy of further research and practice attention.

Bikes and bike networks are for younger fit bicyclists, and the U.S. continues to not serve older individuals, with and without dementia, and caregivers. Biking is a sustainable form of transportation, and expanding the biking population would address climate change while improving health. To our knowledge, research has not been conducted in which seniors indicate their preferences for bike styles and networks, health concerns, and desires to bike. Conducted in four senior-living communities in New England, the Visual and Verbal Preference Survey involved 178 participants (female—50%/male—29.8%; age 20–85 52.8%; age > 85 41.6% with 19.6% missing gender and 5.6% missing age). Bike test riding in two senior communities involved 50 participants (female—50%/male—40%; age 66–75 14%; 76–85 60%; age 86–95 16% with 10% missing gender and age). Seniors preferred the adult tricycle, followed by the three- and four-wheeled two-seated bikes, and to bicycle for 30 min 2 days a week, have a bathroom break every hour, and have a bicycle loop. Balance and fear of falling were major concerns, but they wanted to bicycle with family, children, and grandchildren. In two of the communities, seniors test rode three senior-friendly Van Raam bikes. The results mirrored the pre-test survey responses, where the adult tricycle (Easy Rider) was most preferred, followed by the three-wheeled two-seater bike (Fun2Go) and the low-step regular bike (Balance Bike). One community purchased the Fun2Go. Full article

Background/Objectives: Individuals with subjective cognitive decline (SCD) have an increased risk of developing dementia, while non-pharmacological multicomponent lifestyle interventions are recommended for prevention/management. The Greek Interventional Geriatric Initiative to Prevent Cognitive Impairment and Disability (GINGER) is such a multicomponent approach, encompassing simultaneous interventions (cognitive training, depression and sleep management, etc.). Exercise/Physical activity (PA) is suggested as one such intervention. This study (i) presents the exercise protocol developed for GINGER and (ii) explores its feasibility (acceptability, applicability, adherence, users’ satisfaction and reliability). Methods: Exercise/PA protocol development, targeting SCD individuals aged > 55 years, utilized relevant guidelines/literature followed by focus group involving exercise specialists. Data were synthesized through consensus to design optimal exercise interventions prescribed on participant’s physical capacity (heart rate, exertion, etc.), comprising 6-month combined aerobic, strengthening, balance and dual-task exercises, delivered 3 times/weekly in two group-based supervised sessions (in-person and online) and one home-based session. Physical outcomes include balance, aerobic capacity [2-Minute Walk Test (2 MWT), IPAQ-7], strength [Hand Grip Strength (HGS), Sit-to-Stand], fear of falling. Eligibility for entering intervention is low IPAQ-7, 2 MWT or HGS scoring. Feasibility was explored with adherence (exercise diaries and Exercise Adherence Rating Scale) and satisfaction (Patient Satisfaction Questionnaire) Results: Intervention was easily delivered with good reliability across testers’ assessments on 13 SCD participants (ICCs = 0.62–0.99), and improved physical outcomes, whereas users’ adherence and satisfaction scored highly. Conclusions: The exercise protocol for SCD was feasible, acceptable, applicable, reliable, demonstrating adherence and satisfaction, while improving physical parameters. It is thus integrated in the GINGER study, where multiple simultaneous interventions will take place to prevent/enhance cognitive function. Full article

We studied the impact of well-designed dementia care environments for people with dementia and how such environments reduce anxiety, alleviate fear, and slow the progression of the disease. The “group home” model has been particularly successful, as it emphasizes “home-like”, family-oriented, and personalized care. A case study of the Yunlin County Elderly Long-Term Care Association showed that this model fostered a sense of belonging and serenity in residents, with high levels of satisfaction and effective design outcomes. The environments researched were found to enhance the well-being and quality of life of people with dementia in Taiwan. Full article

Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. There is currently no effective treatment for VCID. Resveratrol (RSV) is considered an antioxidant; however, our group has observed pleiotropic effects in stroke paradigms, suggesting more effects may contribute to mechanistic changes beyond antioxidative properties. The main goal of this study was to investigate if administering RSV twice a week could alleviate cognitive declines following the induction of a VCID model. Additionally, our aim was to further describe whether this treatment regimen could decrease cell death in brain areas vulnerable to changes in cerebral blood flow, such as the hippocampus and medial septum. We hypothesized RSV treatments in a mouse model of gradual cerebral hypoperfusion protect against cognitive impairment. We utilized gradual bilateral common carotid artery stenosis (GBCCAS) via the surgical implantation of ameroid constrictor devices. RSV treatment was administered on the day of implantation and twice a week thereafter. Cerebral perfusion was measured by laser speckle contrast imaging, and cognitive functions, including the recognition memory, the spatial working memory, and associative learning, were assessed by novel object recognition (NOR), Y-maze testing, and contextual fear conditioning (CFC), respectively. RSV treatment did not alleviate cerebral perfusion deficits but mitigated cognitive deficits in CFC and NOR after GBCCAS. Despite these deficits, no hippocampal pathology was observed; however, cholinergic cell loss in the medial septum was significantly increased after GBCCAS. This cholinergic cell loss was mitigated by RSV. This study describes a novel mechanism by which chronic RSV treatments protect against a VCID-induced cognitive decline through the preservation of cholinergic cell viability to improve memory performance.

Objective: Dementia is one of the most common diseases in the elderly population. The aim of this study was to reveal the experiences of individual care workers performing oral care for dementia patients. The oral health of the elderly is in a critical state and in most cases not enough attention is paid to this problem. Material and methods: A qualitative research method was chosen for the research. The data collection instrument was a semi-structured interview, the purpose of which was to reveal the experience, knowledge, and attitude of individual care workers towards the importance of oral care and the oral hygiene habits of patients with dementia. The number of research informants was 10. The inclusion criteria were individual care workers working in social care institutions who were responsible for the personal care of dementia patients. Results: The analysis of the study showed that the main obstacles facing individual care workers in performing oral care for dementia patients are related to their cognitive disorders. For this reason, unreasonable fears of patients may arise, which also affect the proper performance of individual oral hygiene and other tasks assigned to employees. Conclusions: The results of the study showed that according the informants’ opinions it is crucial to take care of dementia patients’ oral care daily. Full article

Neurological disorders represent the primary cause of disability and the secondary cause of mortality globally. The incidence and prevalence of the most notable neurological disorders are growing rapidly. Considering their social and public perception by using different platforms like Twitter can have a huge impact on the patients, relatives, caregivers and professionals involved in the multidisciplinary management of neurological disorders. In this study, we collected and analyzed all tweets posted in English or Spanish, between 2007 and 2023, referring to headache disorders, dementia, epilepsy, multiple sclerosis, spinal cord injury or Parkinson’s disease using a search engine that has access to 100% of the publicly available tweets. The aim of our work was to deepen our understanding of the public perception of neurological disorders by addressing three major objectives: (1) analyzing the number and temporal evolution of both English and Spanish tweets discussing the most notable neurological disorders (dementias, Parkinson’s disease, multiple sclerosis, spinal cord injury, epilepsy and headache disorders); (2) determining the main thematic content of the Twitter posts and the interest they generated temporally by using topic modeling; and (3) analyzing the sentiments associated with the different topics that were previously collected. Our results show that dementias were, by far, the most common neurological disorders whose treatment was discussed on Twitter, and that the most discussed topics in the tweets included the impact of neurological diseases on patients and relatives, claims to increase public awareness, social support and research, activities to ameliorate disease development and existent/potential treatments or approaches to neurological disorders, with a significant number of the tweets showing negative emotions like fear, anger and sadness, and some also demonstrating positive emotions like joy. Thus, our study shows that not only is Twitter an important and active platform implicated in the dissemination and normalization of neurological disorders, but also that the number of tweets discussing these different entities is quite inequitable, and that a greater intervention and more accurate dissemination of information by different figures and professionals on social media could help to convey a better understanding of the current state, and to project the future state, of neurological diseases for the general public.

The COVID-19 pandemic generated, in addition to severe symptoms, hospitalizations and deaths worldwide, as well as stress from the fear of the disease and social uncertainties, from restriction measures and social isolation. Stress from social isolation impacts mental health, aggravating existing conditions and triggering neuropsychiatric symptoms in individuals with biopsychosocial vulnerability. During and immediately after the period of social restriction imposed by the pandemic, the scientific community carried out several research protocols. These revealed results that relevantly demonstrate the harmful effect of the stress induced by the pandemic situation. This narrative review reports and discusses research results demonstrating impairments in psychiatric disorders such as autism spectrum disorder, dementia, eating disorders, schizophrenia, anxiety, and depression. In this sense, the community has identified a significant negative influence of social isolation on the mental health of individuals through the modification of individual routines and the absence of social interactions. Moreover, the community identified perceived differences related to the impacts on men and women. In addition to studies showing the effect of social isolation on disorders, an evaluation of protocols with some possible therapeutic intervention strategies during times of social restriction was developed.
