Ischemic stroke associated movement disorders can be seen as the first sign of a stroke or as a delayed onset development. Tremor after a stroke is a rare finding among movement disorders. In addition to reports of tremor caused by cerebral infarction of varied locations, data on the disappearance
OBJECTIVE
Hand tremor has been rarely described as a manifestation of stroke.
METHODS
Three patients developed delayed onset hand tremor due to cerebral infarctions on the contralateral side, two in the caudate nucleus and the third in the thalamus. The tremors of all three patients were similar to
A 72-year-old woman experienced a sudden onset of spontaneous tremor and myoclonus of right extremities that completely subsided 24 hours after onset. Neuroimaging study revealed an infarct at the left ventral portion of thalamus and subthalamic nucleus. Concomitant dyskinetic movement disorders
We present a patient with essential tremor who spontaneously improved after a sensorimotor stroke related to a small cortical infarct near by the left precentral region of the brain. This finding supports the presence of cortical or transcortical motor loops that are likely involved in essential
BACKGROUND
Focal thalamic lesions have been associated with a variety of involuntary movements such as tremor, dystonia, and chorea-ballism.
METHODS
We describe a patient with severe hyperkinesias of the right arm secondary to a thalamic infarction in the left postero-ventral region of the
Mechanism of essential tremor remains unknown. Central oscillators, postulated in thalamus, inferior olive, and spinal cord are thought to be important to form rhythmicity, and finally to stimulate spinal or medullary motor cells, leading trembling muscle contraction, tremor. Among several subtypes
After infarction of the left superior cerebellar peduncle and dentate nucleus, a patient developed tremor of the left upper limb beginning on the twelfth day followed by palatal tremor appearing 10 months after infarction. Surface electromyogram revealed a difference in the frequency of the tremor
We report a 67-year-old man who developed yes/yes head tremor without appendicular tremor six weeks after right occipital and bilateral cerebellar infarction. The tremor was resting-postural. Its activity increased with excitement, decreased either after ethanol, lateroflexion or rest and stopped at
Body lateropulsion is known to be caused commonly by lateral medullary lesions but rarely by pontine lesions. It is also known to be associated with lesions of the dorsal spinothalamic tract or ascending graviceptive pathways. We herein report the case of a 75-year-old woman presenting with
Holmes tremor (HT) arises from disruption of the cerebellothalamocortical pathways. A lesion can interrupt the projection at any point, resulting in this tremor. We describe a case of HT due to the rare artery of Percheron infarct and its successful treatment using deep brain Stereotactic thalamotomy has been used with some benefit in the treatment of essential tremor. We report a 73-year-old woman whose essential tremor of the right hand spontaneously disappeared after thalamic infarction. She had suffered hand tremor of the right hand for seven years. One morning, she
The occurrence of tremor after thalamic lesions is well known. Delayed rubral tremor secondary to bilateral thalamic infarction is a rare finding and has not been reported previously in childhood. We present two children with a combined resting-postural-kinetic tremor caused by bithalamic
BACKGROUND
Hand tremor is a rare manifestation of stroke, and writing tremor has not been reported to be produced by stroke. We describe a patient who developed a unilateral hand tremor mimicking primary writing tremor after discrete cerebral cortical infarction.
METHODS
A 67-year-old man developed
BACKGROUND
Movement disorders, when caused by ischemic stroke, may appear as initial manifestation or after a variable interval of time. Among postictal movement disorders tremor is an uncommon manifestation. Holmes' tremor, which is a mixed tremor, is the most frequent type of tremor after stroke.
BACKGROUND
Holmes' tremor is an uncommon neurologic disorder following brain insults, and its pathogenesis is undefined. The interruption of the dento-rubro-thalamic tract and secondary deterioration of the nigrostriatal pathway are both required to initiate Holmes' tremor. We used nuclear medicine
