Disease burden of undiagnosed patients from a holistic perspective


Patients without diagnosis can have a wide range of symptoms. A misdiagnosis or a delayed diagnosis can have a serious impact on their quality of life.


A better understanding of the symptoms experienced by undiagnosed patients will allow us to group them and analyse the burden of disease. This will help us to identify unmet needs and improve their quality of life from a 360-degree perspective.


A clinical and psychosocial study that will analyse information provided directly by patients and their caregivers through the use of validated scales to report on quality of life data.
