The tremors linked with essential tremor are generally action tremors, which means they occur during intentional movements rather than when the body is at rest. [ 12 ] In mild cases, ET can manifest as the inability to stop the tongue or hands from shaking, the ability to sing only in vibrato , and difficulty doing small, precise tasks such as ...
When experiencing an intention tremor, one often overshoots or undershoots one's target, a condition known as dysmetria. [1] [2] Intention tremor is the result of dysfunction of the cerebellum, particularly on the same side as the tremor in the lateral zone, which controls visually guided movements. Depending on the location of cerebellar ...
Tremors that are worse with posture against gravity include essential tremor and exaggerated physiological tremors. [20] During intentional movement (e.g. finger-to-nose test) Intention tremors: Intention tremors are tremors that are worse during intention, e.g. as the patient's finger approaches a target, including cerebellar disorders. [18]
Clinical findings are divided into major and minor symptoms. Major symptoms include intention tremor and gait ataxia. Minor symptoms such as parkinsonism, short-term memory deficit, and executive function decline can further contribute to a diagnosis of FXTAS. Radiological findings are similarly divided into major and minor categories.

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 ...
Essential myoclonus occurs in the absence of epilepsy or other apparent abnormalities in the brain or nerves. It can occur randomly in people with no family history or among members of the same family, indicating that it sometimes may be an inherited disorder. Essential myoclonus tends to be stable without increasing in severity over time.
Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
