Parkinson's Disease. For many people with Parkinson's disease, fatigue is just as disabling and unpleasant a symptom as the motor slowing or the trembling. Fatigue undermines all kinds of daily activities and rehabilitation programs. It feeds into our emotional reactions to Parkinson's symptoms and makes them all the harder to bear.
Parkinsonâs Disease (PD) is a chronic, progressive disorder that affects nerve cells deep in the brain responsible for planning and controlling body movement.Dopamine is a chemical used in body movement.When the dopamine-producing nerve cells die, symptoms such as tremor, slowness, stiffness, and balance problems begin to occur. The cause of Parkinson's is largely unknown, and the disease cannot be cured at this time.o understand Parkinson's, it is helpful to understand how the nervous system works and how PD affects normal functions (see Anatomy of the Brain). Nerve cells, or neurons, are the basic building blocks of the nervous system. The neuron is responsible for sending and receiving nerve impulses or messages.
