Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean kurtosis	A measurement of kurtosis diffusion signal in pseudobulbar affect-affiliated brains areas (prefrontal lobe, pons, cerebellum, motor cortex, temporal lobe) derived from Diffusion kurtosis imaging (DKI)-MRI	Baseline measurement and up to 6 month follow-up measurements
Primary	Spectral connectivity	Estimation of connectivity (correlation between spikes of activity) between pseudobulbar affect afflilated cortical brain areas (prefrontal cortex, motor cortex, temporal lobe) derived through resting state magnetoencelphalography (MEG)	Baseline measurement and up to 6 month follow-up measurements
