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]
Tremors can start at any age, from birth through advanced ages (senile tremor). [62] [63] Any voluntary muscle in the body may be affected, although the tremor is most commonly seen in the hands and arms and slightly less commonly in the neck (causing the person's head to shake), tongue, and legs. A resting tremor of the hands is sometimes present.

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 ...
At rest: Resting tremors: Tremors that are worse at rest include Parkinsonian syndromes and essential tremor if severe. This includes drug-induced tremors from blockers of dopamine receptors such as haloperidol and other antipsychotic drugs. During contraction (e.g. a tight fist while the arm is resting and supported) Contraction tremors
Asterixis (more colloquially referred to as flapping tremor) is not actually a tremor, but rather a negative myoclonus.This movement disorder is characterized by an inability to maintain a position, which is demonstrated by jerking movements of the outstretched hands when bent upward at the wrist (which can be similar to a bird flapping its wings, hence the name "flapping tremor").
Proper diagnosis of these neurodegenerative disorders is important as individual treatments vary depending on the condition. The nuclear medicine SPECT procedure using 123 I ‑ iodobenzamide (IBZM), is an effective tool in the establishment of the differential diagnosis between patients with PD and Parkinson-plus syndromes.
Tremors are symmetric about a midpoint within the movement, and both portions of the movement occur at the same speed. Unlike the other hyperkinetic movements, tremors lack both the jerking associated movements and posturing. [4] Essential tremor (ET), also known as benign essential tremor, or familial tremor, is the most common movement ...
