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.nformation comes to a central area of the brain called the striatum, which works with the substantia nigra to send impulses back and forth from the spinal cord to the brain. The basal ganglia and cerebellum are responsible for ensuring that movement is carried out in a smooth, fluid manner (Fig. 2). Figure 2.
