Spoke with my mother and sister a night or so ago. Mum has moved back home, during the daytime hours. Spends the nights at her sister's place is what they told me. Apparently there was some fighting between my sister and her husband about money and other issues that mum couldn't listen to any more. I'm not sure if this is good or bad. We'll see.

Apparently the brain test she had needs to be reinforced with another one, the results will be coming in the next few weeks.
