SOD1 G93A mice receiving corticosterone (SOD1 + CORT) had significant (p = 0.03) earlier onset of tremor (median onset = 79 days) compared to SOD1 + V (median onset = 87 days), higher neurological score, decreased latency to fall and decreased normalized grip strength (Fig. 9b–e). Here, SOD1 is linked to Tremor.
