Potential attributions for a neurobehavioral symptom.

Fig. 2. This illustration depicts the multiple potential explanations, represented in colored circles, for an example neurobehavioral symptom at the figure's center, i.e., purposeful collision. While purposeful collision may broadly be appraised as aggressive, in MPS II it can be a behavioral sign of sensory seeking, attempting to engage socially, communicating, or others.
