A variety of recovery patterns have been reported in the literature:
+parallel (both/all languages are impaired and recover at the same
rate)(the commonest pattern)
+differential (impairment and recovery occur to different degrees in
each language)
+successive (recovery of one language has reached a plateau before
recovery of another begins)
+anatagonistic (one language regresses as another improves)
+selective (impairment is restricted to one language)
+mixed (two/more languages are blended at all linguistic levels)
If you are interested in these phenomena, a good starting place is:
