Vascular Pakinsonism

Does anyone have an experience of Vascular Parkinsonism? My mum has this, I think its quite advanced. She needs to be cared for full time and is completely wheel chair bound. She doesn’t remember where she is and has no concept of time. I’m looking for people who have experience Vascular Parkinsonism as we are not being support by any doctors at present and would like to hear other peoples stories about this horrible condition.
