In Sumire Negishi's circumstance, the biggest culprit to her demise could be due to dysautonomia. Here are some problems associated with this condition:
- Inability to stay upright
- Irregular heartbeat
- Breathing difficulties
- Temperature regulation problems
- Low blood pressure
All these are difficult enough to counter. Add in the fact that advanced Parkinson’s disease may cause serious motor functions, as well as stiffness of the muscles. These could have contributed to Sumire Negishi’s succumbing to hypothermia that day.
