Abstract
Conceptual modelling of nodding syndrome (NS) has hardly been considered in most
scientific literature although symptoms of the disease have been widely studied. A conceptual
model is a representation of hypothesis about a system under investigation and enables a
comparison between hypothesis and data. Since nodding syndrome is an unexplained
neurological illness that mainly affects children aged between 5 to 15 years, without specific
diagnosis and treatment, the aetiology remains unknown and under investigation, conceptual
modelling may be a crucial ingredient in understanding the disease. The purpose of the study
is therefore, to represent nodding syndrome occurrence and immune-pathogenic pathways in
the causation of nodding syndrome using system dynamics approaches. We have used
systematic review method to filter literature on nodding syndrome from the year. We also
used Systems Dynamic Approach and we emphasized confirmed scientific investigation to
enable the relationships conform to reality. Vensim software was preferred for
implementation of the casual-loop diagrams. Microsoft Office Visio 2007 was identified as
suitable for implementation of the sequence conceptual model of nodding syndrome for its
ability to show interactions between electrolytes and other actors. Our findings were that
system dynamics approach has not been used research of nodding syndrome. More so,
conceptual modeling was not considered by most articles.
