NPR’s Jon Hamilton spotlights Prof. Li-Huei Tsai’s work developing a noninvasive technique that uses lights and sounds aimed at boosting gamma waves and potentially slowing progression of Alzheimer’s disease. "This is completely noninvasive and could really change the way Alzheimer's disease is treated," Tsai says.
Scientific American reporter Leslie Nemo spotlights postdoctoral fellow Matheus Victor’s photograph of a petri dish full of neurons. Nemo writes that Victor and his colleagues hope the “rudimentary brain tissue will reveal why a new therapy might alleviate Alzheimer’s symptoms.”
Boston Globe reporter Corrie Pikul spotlights Prof. Li-Huei Tsai’s work finding that exposure to a specific pattern of rhythmic lights and sound bursts could potentially serve as a non-invasive treatment for Alzheimer’s. “These are really surprising findings,” says Tsai. “We are seeing multiple different cellular responses that are consistent with increased brain health.”
MIT researchers have developed an AI system that can predict Alzheimer’s risk by forecasting how patients will perform on a test measuring cognitive decline up to two years in advance, reports Casey Ross for STAT.
Popular Science reporter Nicole Wetsman writes that MIT researchers have found light pulses could potentially be used to help ease the symptoms of Alzheimer’s disease. The researchers found that “light pulses and gamma oscillations protect against neurodegeneration and change the expression of genes involved with inflammation and neuron health in the brains of mice.”
Los Angeles Times reporter Melissa Healy writes that a new study by MIT researchers provides evidence that acoustic and visual stimulation could improve Alzheimer’s symptoms. “The study’s central finding — that inducing electrical synchrony touched off such a widespread range of effects — suggests there might be a single key lever that can preserve or restore order in brains made 'noisy' by age and disease,” Healy explains.
A study by MIT researchers shows that exposing patients to flashing light and pulsing sounds could reverse Alzheimer’s symptoms, reports Angus Chen for Scientific American. “This is the first time we’ve seen that this noninvasive stimulation can improve cognitive function,” says Prof. Li-Huei Tsai.
New York Times reporter Pam Belluck writes that MIT researchers have found exposure to a specific combination of light and sound could improve Alzheimer’s symptoms. “It’s stunning that the intervention had beneficial effects on so many different aspects of Alzheimer-like pathology,” said Dr. Lennart Mucke, director of the Gladstone Institute of Neurological Disease.
MIT startup Lyndra has found that an ingestible device originally developed by researchers from MIT and Brigham and Women’s Hospital can help tackle the problem of medication adherence, reports Kate Sheridan for STAT. The new technology could make it possible for patients to take “one pill a week for conditions as varied as Alzheimer’s, addiction, allergies, malaria, schizophrenia, high cholesterol, and HIV.”
Molly Webster of WNYC’s Radiolab visits the Picower Institute to learn more about how researchers are investigating new techniques that might eventually be used to treat Alzheimer’s disease. Prof. Li-Huei Tsai speaks about her group’s work using flickering light to reduce the beta amyloid plaque found in Alzheimer’s patients, and graduate student Dheeraj Roy discusses his work recovering memories with light.
A new study led by Prof. Li-Huei Tsai reveals more information about the possible link between Alzheimer’s disease and the gene variant APOE4, writes Martin Finucane for The Boston Globe. The researchers discovered that by editing the gene into the more common APOE3 variant, “they could eliminate the signs of Alzheimer’s in brain cells,” said Finucane.
The Nature Podcast, hosted by Adam Levy and Shamini Bundell, highlights research from the Haystack Observatory and Prof. Li-Huei Tsai’s findings around Alzheimer’s and its connection to brain waves.
Prof. Li-Huei Tsai found that use of a small flickering light could prevent plaque-forming proteins in the brains of mice - a practice that has potential to combat Alzheimer’s disease. “The work offers the possibility of forestalling or even reversing the damage caused by such conditions without using a drug,” writes Helen Thomson for Nature.
Boston Magazine reporter Jamie Ducharme spotlights Prof. Li-Huei Tsai’s quest to vanquish Alzheimer’s disease. Ducharme writes that Tsai’s work, including two recent papers outlining potential treatments for Alzheimer’s, “established her as a bona fide rock star in the neuroscience world.”
Damien Garde of STAT highlights Prof. Li-Huei Tsai’s research on the HDAC2 enzyme in an article about Alzheimer’s research. “If we can reduce HDAC2 expression in Alzheimer’s disease models, we can reactivate the genes [that] actually rescue learning and memory,” says Prof. Tsai.
