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.
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).
Orthostatic intolerance (OI) is the development of symptoms when standing upright that are relieved when reclining. [1] There are many types of orthostatic intolerance. OI can be a subcategory of dysautonomia, a disorder of the autonomic nervous system [2] occurring when an individual stands up. [3]
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]
Resting tremor is the most common, but kinetic tremors—occurring during voluntary movements—and postural tremor—preventing upright, stable posture—also occur. [19] Tremor largely affects the hands and feet: [ 19 ] a classic parkinsonian tremor is " pill-rolling ", a resting tremor in which the thumb and index finger make contact in a ...
Parkinsonian gait (or festinating gait, from Latin festinare [to hurry]) is the type of gait exhibited by patients with Parkinson's disease (PD). [2] It is often described by people with Parkinson's as feeling like being stuck in place, when initiating a step or turning, and can increase the risk of falling. [3]

Multiple system atrophy (MSA) is a rare neurodegenerative disorder [1] characterized by tremors, slow movement, muscle rigidity, postural instability (collectively known as parkinsonism), autonomic dysfunction and ataxia.
