By analyzing epigenomic and gene expression changes that occur in Alzheimer’s disease, researchers identify cellular pathways that could become new drug targets Alzheimer’s disease affects more than 6 million people in the United States, and there are very few FDA-approved treatments that can slow the progression of the disease. In hopes of discovering new targets …
A potential new Alzheimer’s drug represses the harmful inflammatory response of the brain’s immune cells, reducing disease pathology, preserving neurons and improving cognition in preclinical tests Though drug developers have achieved some progress in treating Alzheimer’s disease with medicines that reduce amyloid-beta protein, other problems of the disease including inflammation, continue unchecked. In a new …
Tactile stimulation improved motor performance, reduced phosphorylated tau, preserved neurons and synapses and reduced DNA damage, a new study shows Evidence that non-invasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer’s disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends …
Neurons that form part of a memory circuit are among the first brain cells to show signs of neurodegeneration in Alzheimer’s disease. Neurodegeneration, or the gradual loss of neuron function, is one of the key features of Alzheimer’s disease. However, it doesn’t affect all parts of the brain equally. One of the first brain regions …
The peptide blocks a hyperactive brain enzyme that contributes to the neurodegeneration seen in Alzheimer’s and other diseases MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer’s disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer’s patients. When the researchers treated mice with a …
‘Single-cell profiling’ is helping neuroscientists see how disease affects major brain cell types and identify common, potentially targetable pathways After decades of fundamental scientific and drug discovery research, Alzheimer’s disease has remained inscrutable and incurable, with a bare minimum of therapeutic progress. But in a new review article in Nature Neuroscience, MIT scientists write that by employing …
MIT researchers report early stage clinical study results of tests with non-invasive 40Hz light and sound treatment A pair of early stage clinical studies testing the safety and efficacy of 40Hz sensory stimulation to treat Alzheimer’s disease has found that the potential therapy was well tolerated, produced no serious adverse effects and was associated with …
In people carrying the APOE4 risk variant, a key brain cell type mismanages cholesterol needed to insulate neurons properly—another sign that APOE4 contributes to disease by disrupting lipids in the brain. It’s well known that carrying one copy of the APOE4 gene variant increases one’s risk for Alzheimer’s disease threefold and two copies about tenfold, …
Study indicates that ailing neurons may instigate an inflammatory response from the brain’s microglia immune cells A new study by researchers in The Picower Institute for Learning and Memory at MIT provides evidence from both mouse models and postmortem human tissue of a direct link between two problems that emerge in Alzheimer’s disease: a buildup …
New research reveals cells that span brain hemispheres to coordinate activity in visual processing centers and shows that Alzheimer’s degrades their structure and therefore their function A new MIT study finds that Alzheimer’s disease disrupts at least one form of visual memory by degrading a newly identified circuit that connects the vision processing centers of …
