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 ...
Cerebellar tremor (also known as intention tremor) is a slow, broad tremor of the extremities that occurs at the end of a purposeful movement, such as trying to press a button or touching a finger to the tip of one's nose. In classic cerebellar tremor, a lesion on one side of the brain produces a tremor in that same side of the body that ...
Charcot's neurologic triad is the combination of nystagmus, intention tremor, and scanning or staccato speech. This triad is associated with multiple sclerosis, where it was first described; [1] however, it is not considered pathognomonic for it. It is named after Jean-Martin Charcot. [2]
Essential tremor is either an action (intention) tremor—it intensifies when one tries to use the affected muscles during voluntary movements such as eating and writing—or it is a postural tremor, which occurs when holding arms outstretched and against gravity.
Symptoms of cerebellar abiotrophy include ataxia or lack of balance, an awkward wide-legged stance, a head tremor (intention tremor) (in dogs, body tremors also occur), hyperreactivity, lack of menace reflex, stiff or high-stepping gait, coarse or jerky head bob when in motion (or, in very young animals, when attempting to nurse), apparent lack ...
Holmes tremor, first identified by Gordon Holmes in 1904, can be described as a wing-beating movement localized in the upper body that is caused by cerebellar damage. [1] Holmes tremor is a combination of rest, action, and postural tremors. Tremor frequency ranges from 2 to 5 Hertz and is aggravated with posture and movement. [1]
A few recently published papers outlined a potential method for treating intention tremor which consisted of cooling the forearm by wrapping it in a cryomanchet using a circulating fluid. After the treatment most patients experienced reduced tremor for up to half an hour. This practical, however short-term treatment can facilitate performing ...
Dysdiadochokinesia is also seen in Friedreich's ataxia and multiple sclerosis, as a cerebellar symptom (including ataxia, intention tremor and dysarthria). It is also a feature of ataxic dysarthria. It is also a feature of ataxic dysarthria.
