Background: Disease-modifying therapies with amyloid-antibodies will soon be available for patients with early Alzheimer's disease, which necessitates diagnostic and therapeutic resources in hospital and outpatient settings.
Methods: The Austrian Alzheimer Society developed an online questionnaire to survey Austrian hospital-based departments of neurology and psychiatry regarding resources for amyloid-antibody therapies.
Results: Between May and October 2023, 30 out of 41 neurology (73%) and 12 out of 33 psychiatry departments (36%) responded.
Objectives: There is evidence that periodontitis can enhance the progression of Alzheimer's disease (AD). The biomarkers beta-amyloid (40 and 42), total tau, and phospho-tau181 (pTau181) in cerebrospinal fluid help to diagnose AD. Saliva is an easy-to-collect fluid and we aim to analyze these biomarkers in patients with periodontitis.

Here we show that long-term post-mitotic culture of human fibroblasts authentically recapitulates and accelerates in-vivo aging signatures. Longitudinal paired transcriptomic-epigenetic analyses revealed that in-vitro aging mirrors in-vivo primary fibroblasts aging, with concordant transcriptional aging pathways and accelerated epigenetic clock aging patterns.

Background: Mild cognitive impairment (MCI) confers a high annual risk of 10-15 % of conversion to Alzheimer's disease (AD) dementia. MRI atrophy patterns derived from automated ROI analysis, particularly hippocampal subfield volumes, were reported to be useful in diagnosing early clinical stages of Alzheimer's disease.
Objective: The aim of the present study was to combine automated ROI MRI morphometry of hippocampal subfield volumes and cortical thickness estimates using FreeSurfer 6.

Alzheimer's disease (AD) imposes a major burden on affected individuals, their caregivers and health-care systems alike. Though quite many risk factors for disease progression have been identified, there is a lack of prospective studies investigating the interplay and predictive value of a wide variety of patient variables associated with cognitive deterioration (defined as key feature of AD progression). Study participants were patients with probable and possible AD, that were assessed at four time points over a period of two years (T1-T4).

Social isolation and loneliness are prevalent health problems impacting well-being and quality of life and may have increased due to pandemic-related restrictions. Methods: This study investigate the influence of the COVID-19 pandemic on loneliness in people visiting a mem40ory clinic between March 2020 and September 2022.

Long-term, large sample-size studies assessing NDDs association with objective sleep measures are scant. We aimed to investigate whether video-polysomnography (v-PSG)-based sleep features are associated with long-term NDDs incidence.

Memory clinics play an important role in enabling early dementia diagnosis and providing support for patients and their caregivers.
Objective: This study investigates the impact of the COVID-19 pandemic and its restrictions on patients of a memory clinic and their caregivers between March 2020 and March 2021.

Alzheimer's disease (AD) is a severe neurodegenerative brain disorder. The determination of beta-amyloid (Aβ)-40, -42, total tau, and phospho-tau-181 (pTau181) in cerebrospinal fluid (CSF) using Lumipulse technology has been established as biomarkers for AD in recent years. As CSF collection is an invasive procedure, one aims to find biomarkers in blood or other human fluids, such as saliva.

Physical activity in outdoor environments has a positive effect on physical and mental health. However, regular and/or extreme mountaineering might share similarities with behavioural addictions and could thus also have a negative impact on health.

Recent studies have revealed health-protective and lifespan-extending effects of dietary spermidine, a natural autophagy-promoting polyamine. Here, we show that dietary spermidine passes the blood-brain barrier in mice and increases hippocampal eIF5A hypusination and mitochondrial function.

The purpose of this study is to investigate whether lipid metabolites and vitamin B12 and folate levels are effective biomarker for an accurate prediction of MCI-to-AD conversion.
Methods: During the standard diagnostic assessment at our memory clinic 48 cognitively healthy subjects and MCI patients were recruited.

Older adults are particularly affected by the current COVID-19 (SARS-CoV-2) pandemic. The risk of dying from COVID-19 increases with age and is often associated with pre-existing health conditions. Globally, more than 50 million-in Austria currently approximately 140,000 people-suffer from dementia.

Neuropsychiatric symptoms (NPS) such as delusions, agitation, anxiety, and hallucinations are present in up to 95% of patients in all stages of dementia. To date, any approved and effective pharmacological interventions for the treatment of NPS are still not available.

Introduction: Depression in old age is associated with functional disabilities, cognitive impairment, lower self-rated quality of life, and increased mortality. The aim of the study was to reveal the prevalence of depression and to investigate the characteristics of patients treated with antidepressants.
Methods: We analyzed data from the Bruneck Study 2010.
Alzheimer´s disease (AD) is a severe neurodegenerative brain disorder characterized by beta-amyloid plaques, Tau pathology, inflammation, neurodegeneration, and cerebrovascular dysfunction. Besides that, alterations in monocytes and platelets have been reported in the blood of Alzheimer patients. In the present study, we measured circulating levels of platelet-monocyte aggregates in EDTA blood of cognitively healthy participants and 40 AD patients, and examined their changes induced by stimulation with beta-amyloid peptides.

Objectives: In this study, we examined the predictive value of depressive symptoms and neuropsychological variables on conversion of MCI to DAT.
Methods: Neuropsychological and clinical follow-up data of 260 MCI patients seen at the Psychiatric Memory Clinic of the Medical University of Innsbruck between 2005 and 2015 were analyzed retrospectively.
