I feel my mom crossed that line last night when she ran off my brother who is her primary caregiver (about the fourth time he has left her in two years due to manic behavior?) and was found OUTSIDE screaming her head off by a neighbor at 3:30 a.m. Only thing the ER found wrong is an elevated ammonia level which is not new. Checked for uti which she gets a lot but they said that showed clear. Do you agree her going outside at that hour crossed that line? She can only walk about 20 steps with a walker!
