Biomedical Scinece and Research Journals | Parkinson’s Disease and Software: The Applicability Challenge
Parkinson’s disease (PD) is a progressive neurodegenerative
movement disease affecting over 5 million people worldwide.
However, there is currently no definitive test for PD by nonspecialist
clinicians, especially in the early disease stages where the
symptoms may be subtle and poorly characterized. Subsequently,
the lack of definitive test for early PD results in a high misdiagnosis
rate (up to 25% by non-specialists) and people can have the
disease for many years before being diagnosed and managed.
Undoubtedly, there is a need for a more accurate, objective means
of early detection, ideally one which can be used by individuals
in their home setting.
In addition, objective measurements of
motor signs are of vital importance for monitoring and developing
disease modifying therapies, particularly for the early stages of
the disease when potential neuroprotective treatments could stop
neurodegeneration.Digital technologies for objectively quantifying PD motor sign
do exist and more new ones are being developed. One of the most
frequently used technologies is finger tapping, where patients
are asked to intermittently press buttons as fast as possible for a
given time.
