Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder.
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]
Four motor symptoms are considered cardinal signs in PD: slowness of movement (bradykinesia), tremor, rigidity, and postural instability. [1] Typical for PD is an initial asymmetric distribution of these symptoms, where in the course of the disease, a gradual progression to bilateral symptoms develops, although some asymmetry usually persists.

Bradykinesia has been shown to precede impairment of executive functions, working memory, and attention. [ 11 ] [ 31 ] These cognitive deficiencies can be tied to nonfunction of the basal ganglia and prefrontal cortex , which is also linked to the motor-dysfunction of hypokinesia. [ 11 ]
Many dog breeds were developed for aggressive tasks like hunting and guarding property – and they are the dogs most likely to cause harm or death. Learn which breeds are more likely to bite in ...
Parkinson-plus syndromes (PPS) are a group of neurodegenerative [1] diseases featuring the classical features of Parkinson's disease (tremor, rigidity, akinesia/bradykinesia, and postural instability) with additional features that distinguish them from simple idiopathic Parkinson's disease (PD).
