Poster: Markov mixture models for longitudinal course of youth bipolar disorder
Bipolar Disorder is characterized by recurrent mood changes ranging from depression, to excessive happiness or irritability. Measuring and making sense of the fluctuations in these moods over time is challenging. To find homogeneous clusters and capture different longitudinal mood change patterns we introduced a Markov mixture model with different transition matrices in an observational study of 412 children and adolescents with bipolar disorder who were followed on average for 341 weeks. The parameters of this model were estimated using the EM algorithm. Our clusters separate out those who tend to stay in a state from those who jump between states more frequently. We will present further results of these analyses and discuss potential clinical implications.
