Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [ 1 ] [ 2 ] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [ 3 ]
As 90 percent of Parkinson's cases are sporadic, the identification of the risk factors that may influence disease progression or severity is critical. [116] [68] The most significant risk factor in developing PD is age, with a prevalence of 1 percent in those aged over 65 and approximately 4.3 percent in age over 85. [117]
Kufor–Rakeb syndrome is associated with mutations in the ATP13A2 gene. [8] The inheritance pattern for KRS is autosomal recessive. [9] If a male and female carrier, who each have one mutation in ATP13A2 have a child, there is a 25% chance the child has KRS, a 50% chance the child is a carrier for KRS, and a 25% chance the child does not have KRS.
The main symptom of DTDS, presenting in 80-99% of DTDS patients, is Parkinsonism. [3] This is a neurological anomaly resulting from degeneration of dopamine-generating cells in the substantia nigra, and is characterized by shaking and tremors, rigidity, slowness of movement, and difficulty with walking and gait.
In addition, dopamine-responsive dystonia is typically characterized by signs of parkinsonism that may be relatively subtle. Such signs may include slowness of movement (bradykinesia), tremors, stiffness and resistance to movement (rigidity), balance difficulties, and postural instability.
The organization notes that the average life expectancy for Parkinson’s disease in 1967 was "a little under 10 years" from the time of diagnosis. Now, that statistic has grown to 14.5 years or ...

At autopsy, many patients diagnosed during life with Parkinson's disease are found actually to have MSA, suggesting that the actual incidence of MSA is higher than that estimate. [4] While some suggest that MSA affects slightly more men than women (1.3:1), others suggest that the two sexes are equally likely to be affected.
