Neural Bases of Vocal Sensorimotor Impairment in Aphasia
Recruiting
Aphasia is the most common type of post-stroke communication disorder characterized by deficits in speech comprehension, production and control. While recovery can be promoted with speech therapy, improvement remains modest and typically requires a large number of sessions contributing to rising health care costs. Traditional aphasia therapy focus on enhancing speech motor output; however, recent evidence suggests that the auditory feedback also plays a critical role in fluent speech. Therefore,... Read More

Neurofeedback to Improve Working Memory in Mild Cognitive Impairment
Recruiting
Mild cognitive impairment (MCI) has been identified as an early phase of Alzheimer's disease (AD), a neurodegenerative disorder expected to affect 13.9 million Americans by 2060.

Osimertinib Alone or With Chemotherapy for EGFR-Mutant Lung Cancers
Recruiting
This study will compare the effectiveness of osimertinib alone with the combination of osimertinib and chemotherapy (carboplatin and pemetrexed) in people with metastatic lung cancer that has a change (mutation) in the gene EGFR. Osimertinib alone is the usual treatment for metastatic EGFR-mutant lung cancer. Researchers think adding chemotherapy to osimertinib could possibly add to the anticancer effects of the usual treatment and help stop cancer from growing or spreading.

Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future.
