Characterizing wandering/psychomotor agitation in patients with dementia using BLE localization and physical movement data

Research & development - Leuven | More than two weeks ago

Using ML techniques to uncover hidden patterns in patient movement

Psychomotor agitation and wandering are typical behavioral symptoms seen in patients with dementia. These symptoms can be indicators of patient distress or agitation events and are correlated with disease severity and progression. Modeling these symptoms has the potential to allow just-in-time interventions, eventually improving a patients’ quality of life and decreasing the burden on caregivers. Within a multimodal sensing study on agitation in dementia, a BLE localization system will be used to track a patient’s movements within an institutional ward. The data from this BLE system can be combined with activity data generated by a wrist-worn wearable to investigate the patterns related to wandering and psychomotor agitation in dementia. To enable the characterization of these symptoms, a data pipeline is required to ingest streaming input data from an API, clean the data, engineer features, and apply modeling techniques.


This master thesis aims to develop a tool that will take streamed data as an input and use this tool to model wandering/psychomotor agitation from location and movement-based data. The student will be involved in setting up an end-to-end data pipeline enabling raw location data input to be engineered into relevant features ready for input into machine learning models, as well as the feature engineering and modelling itself.


Specific thesis objectives:

  • Study and understand the concept of agitation in dementia, the role psychomotor agitation and wandering play, and why this has an impact on the healthcare system
  • Contribute substantially to the set-up of an end-to-end data pipeline
  • Develop models of wandering/psychomotor agitation based-on activity and location data



  • Interest and enthusiasm for data science particularly in the healthcare field
  • Experience with Python (or related language) &/or strong affinity for programming
  • Knowledge of data analysis principles (data cleaning/feature engineering)
  • Basic knowledge and/or interest in machine learning

Type of project: Thesis

Duration: 6-9 months

Required degree: Master of Engineering Technology, Master of Science, Master of Engineering Science, Master of Bioengineering

Required background: Biomedical engineering, Bioscience Engineering, Computer Science, Electrotechnics/Electrical Engineering
