No doubt in my mind she has Parkinson’s disease. She can’t hide it much longer. Her hands give it away. Also the strangling fits. The brace would keep her back from jerking.
Good description. She’s just plain nasty. Inside and out.
I haven't seen any severe symptoms yet. In general at her age a Parkinsons patient will live 10-20 years (or more) and die of something else. Also I have not seen Parknsons patients bundled up. On the contrary I have seen heat stroke like symptoms in summer heat.
