what is the main age of onset for bpi ?
There was a younger (average age=3) and narrower age range (1â5) for the âby natureâ group. This compared to an age range of 1â13 for episodic (average age=7). The 8 âby natureâ children were risk rated as either low risk (n=1) or moderate (n=2) or high risk (n=5). Three with the âhighestâ risk have onset with BPI.
