Filter by:Dementia creates a great personal and societal burden and there are currently no treatments to stop memory loss. Many patients with dementia take medications to treat other conditions, e.g. high blood pressure and cholesterol. Some of these medications may have central effects on the pathophysiological processes leading to dementia. Medication repurposing is a cost and time-effective way to discover new treatments. Swedish registers are a unique tool to detect medication candidates for repurposing. The Swedish Dementia Registry (SveDem) has >100000 patients and ca. 144000 measures of cognition over time (measured with the Mini-Mental State Examination-MMSE), making it perfect to examine whether certain medications are associated with less cognitive decline in patients with dementia. Cholesterol and kidney function affect treatment and cognition and are available for 25000 patients. The investigators propose a study combining traditional cohort studies and newer artificial intelligence (machine learning) techniques to detect medications associated with slower cognitive decline in patients from SveDem. The investigators will test pre-specified hypotheses since the investigators suspect specific medications are better candidates to prevent cognitive decline, but the investigators will also let the machine learning algorithms explore the data to find associations that the investigators do not suspect in advance. Finally, the candidate medications will be tested in animal and cellular models to determine the mechanisms of their effects.
In this trial, the safety and effect of daily exposure to light and sound stimulation on people with mild Alzheimer's Disease (AD) will be studied. COVID-19 Amendment: Due to the ongoing suspension of all in-person humans subject research across MIT in response to the COVID-19 pandemic, all enrolled participants who have not completed their 6-month visit will have their visit postponed to 9 months with a follow up at 18 months. Subjects who have completed their 6-month visit will still be instructed to continue and return at Month 12 for an evaluation. OPTIONAL: If the subject would like to come in for an evaluation between Month 9 and 18, we will invite participants to come on Month 12 to complete cognitive testing and EEG.
The purpose of this study is to identifying the intramuscular dose equivalent to the 4mg intravenous dose and assess its safety and tolerability as a weekly injection.
The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
Alzheimer disease is the most common of the neurodegenerative diseases. Epilepsy and sleep wake disorders are co-morbid conditions of Alzheimer disease. The investigators propose a prospective study using long-term EEG monitoring in combination with polysomnography to determine prevalence of epilepsy and sleep wake disorders in Alzheimer disease, and correlate these findings with clinical data, Alzheimer disease biomarkers and imaging studies (MRI and amyloid/tau-PET). In selected patients, the investigators will perform EEG studies with foramen ovale electrodes. The ultimate goal is to improve the outcome of patients with Alzheimer disease by early treatment of epilepsy and restoring sleep-wake disturbances.
