Hi,
It's good to see you've managed to get some info and good links. What I know is -
Parkinsons can be broadly divided into five stages. The first two areearly onset, and limited symptoms, the third is loss of mobility. From ehat you have said, it sounds as if your Gran is at stage 3 or higher. Stage 4 sees movements becomign far more rigid and slower (bradykenesia sp?) This si the stage where most perople lose independance. Tremors may lessen or dissapear.
The final stage is where the patient loses all bodily control, usually requiring 1to1 care. The disease can literally efeect everything, swallowing, bladder/bowel control, eyes, etc as it takes control of all the muscles.
However, Parkinsons in itself is not terminal. It does however excerbate other illnesses, so usually the end comes about due to a secondary illness. It can be hard to believe, but even in the very final stages of parkinsons, a patient may live for many years to come if they are otherwise healthy.
Roughly one third of patients with parkinsons develop dementia at some stage. Bearing in mind 1/3 of over 80 year olds develop some form of dementia this figure is not massively high.
Other less obvious symtoms you might like to be aware of (don't always occur) are tiredness, confusion, depression, skin problems, and memory problems. It can be easy for patients in nursing care to lose touch with reality. Frequent visitors, photographs, talkign about the past etc. will all help reduce confusion and disorientation. (i think it is called orientation therapy or soemthing)
Treatment wise, there are lots of different drugs available, it is a matter of finding what works, and balancing the side effects, most commonly shaking/tremors. A lot of research is beign doen into parkinsons, and new treatments are being investigated and trialed all the time. Surgery may also be an option, but is not suitable for all patients.
Holp that helps, and I would jsut advise that you push for as much help as you can for her, as parkinsons can go on for a long time. She can be referred to a neurology, speech therapy, occupational therapy, physio, diaticians. Parkinsons is a horrible illnessm, for your gran and all your family, I wish you all the best. x x
