This non-contact device measures speech patterns to provide an immediate, objective diagnosis of a person’s neurological state. The technology, particularly useful for identifying Parkinson’s disease, can even be used to evaluate patients in remote locations by analyzing data from real-time phone calls or previously recorded conversations. More than 1.5 million Americans have Parkinson’s disease. Another 3 million people in the U.S. suffer from some form of dementia, such as Alzheimer’s disease. These figures are expected to increase substantially over time as the population ages. Though most Parkinson’s disease and dementia diagnoses are made for patients 50 years and older, early detection is important for research and treatment. Clinicians typically identify these conditions by ordering a series of expensive or time-consuming tests, including cognitive performance exams and brain imaging procedures. Researchers at the University of Florida have developed a tool that can objectively diagnose a patient’s neurological condition without the need for lengthy tests or costly equipment.


Tool that objectively assesses a patient’s neurological state without the need for direct contact, facilitating the diagnosis of neurological diseases, such as Parkinson’s disease


  • Eliminates the need for physical contact, making expensive and complicated sensors or hardware unnecessary
  • Allows for remote data acquisition and diagnosis, enhancing versatility and convenience
  • Automates processes from data acquisition to diagnosis, delivering an objective assessment for more accurate diagnoses


This diagnostic tool remotely gathers and analyzes physiological and acoustic data to provide an objective assessment of a subject’s neurological state. All information is gathered via patented data acquisition technology. The device would prove useful as a remote patient monitor and diagnostic tool, but it is also appropriate for a host of other applications.
