Intention tremors that are caused by normal, everyday activities, such as stress, anxiety, fear, anger, caffeine, and fatigue, do not seem to result from damage to any part of the brain. These tremors, instead, seem to be a temporary worsening of a small tremor that is present in every human being. These tremors generally go away with time. [5]
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]
It is usually reversible once the cause is corrected. This tremor classically has a frequency of about 10 Hz. [5] Psychogenic tremor (also called hysterical tremor and functional tremor) can occur at rest or during postural or kinetic movement. The characteristics of this kind of tremor may vary but generally include sudden onset and remission ...
Essential tremor is a progressive [8] [9] [10] neurological disorder, and the most common movement disorder. Though not life-threatening, it can certainly be debilitating. Its onset is usually between 40 and 50 years of age, but it can occur at any age. [11] The cause is poorly understood.

Akathisia (IPA: /æ.kə.ˈθɪ.si.ə/) is a movement disorder [5] characterized by a subjective feeling of inner restlessness accompanied by mental distress and/or an inability to sit still.
A Cochrane review published in 2016 reported moderate-quality evidence that a single Botulinum toxin-B treatment session could improve cervical dystonia symptoms by 10% to 20%, although with an increased risk of dry mouth and swallowing difficulties. [22] Another Cochrane review published in 2020 for Botulinum toxin-A found similar results. [23]
Benign fasciculation syndrome (BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet.
