Logopenic progressive aphasia

This study tests whether an AI tool can help radiologists read brain CT and MRI scans more accurately and quickly. Researchers will compare how well doctors, AI alone, and doctors using AI together can spot abnormalities, urgent findings, and classify diseases. The goal is to red…

This study tests whether a safe, painless brain stimulation technique called tDCS can improve verbal learning in people with Alzheimer's disease. Researchers will compare active stimulation to a sham (fake) version in 90 participants with typical or language-based Alzheimer's. Th…

This study tests whether a home-based brain stimulation device (tDCS) combined with activity therapy can help improve cognitive and language problems in people with stroke, brain tumors, or neurodegenerative conditions like Parkinson's or Alzheimer's. Fifty-five participants will…

This study tests two types of speech therapy for people with primary progressive aphasia, a brain disorder that slowly destroys language skills. Sixty participants will work on word retrieval or script practice with a clinician and at home. Researchers will measure changes in com…

This study tests a speech-language telerehabilitation program for people with primary progressive aphasia (PPA), a dementia that slowly destroys language abilities. The program includes online therapy sessions and care partner training. Researchers will enroll 21 participants to …

This study uses special brain scans (PET imaging) to measure two key proteins, amyloid and tau, in people with different forms of Alzheimer's disease. Researchers want to see how these protein levels change over one year. The study involves 60 adults with typical or atypical Alzh…

This study aims to learn more about diseases that affect the brain, such as Parkinson's disease and different types of dementia. Researchers will follow 500 adults with symptoms of these conditions over time, using brain scans and genetic tests to see how the diseases progress. T…
