Parkinson-plus syndromes are a group of neurological conditions that are similar to Parkinson's disease but have unique characteristics. These syndromes can be hard to diagnose because the symptoms mimic other conditions. Following are the four most common types of Parkinson-plus syndromes.
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.
