Group Comparisons of Diffusivity Values bw ALS Patients & Healthy Controls

Effect of group differences along the TBSS fiber tract skeleton. Effects were at thresh hold at p<0.05, corrected for multiple comparisons. A) blue: comparison between cognitively intact ALS-patients to healthy controls; B) red  =  comparison between cognitively impaired ALS-patients to healthy controls; FA  =  fractional anisotropy; MD  =  mean diffusivity; AD  =  axial diffusivity; RD  =  radial diffusivity   

Group comparisons of diffusivity values between ALS-ni patients and ALS-ci patients

Effect of group differences along the TBSS fiber tract skeleton. Effects were at threshold at p<0.05, corrected for multiple comparisons. Violet: comparison between cognitively intact ALS-patients to cognitively impaired ALS-patients; MD  =  mean diffusivity; AD  =  axial diffusivity; RD  =  radial diffusivity
