Unilateral and pseudoathetosis

Introduction Unilateral and pseudo-hand and foot movements: Cerebrovascular disease or other causes of deep sensory disturbances, unilateral athetosis and pseudoathetosis are not basal ganglia lesions. Thalamic ataxia can cause unilateral and pseudo-acromegaly.

Cause

The causes of thalamic ataxia can be vascular, tumor and trauma. In addition to the contralateral half-sensual ataxia, there may be spontaneous pain and shallow sensory disturbance in the contralateral half, and the ataxia is more important than the lower limb.

Because the middle abdomen nucleus of the thalamus is associated with the cerebellum, the cerebellar lesions are accompanied by cerebellar symptoms. Thalamic lesions cause deep sensory disturbances. It can be seen that the movements of the hands and feet are obvious, especially in the hands, that is, the so-called thalamic uneasiness, when the eyes are closed, the hand can not maintain a certain posture and the finger is fingering movement, which is caused by the positional dysfunction of the hand. (false hand and foot Xu move).

Differential diagnosis

Identification of acromegaly

The hand and foot hyperkinetic movements unique to the hand and foot hyperkinesis are compulsory movements of the hands and feet that constantly make slow, crooked or creepy shapes. These actions are prominent at the proximal end of the extremities of the extremities. When the lower limbs are involved, the big toe often falsifies spontaneously, causing a false Babinski sign. Sometimes the face can be affected, and the patient often frowns and looks like a variety of faces. When the throat muscles and the tongue muscles are involved, the speech is unclear, the articulation is difficult, the tongue sometimes retracts when it is extended, and the swallowing also has obstacles. It can be accompanied by a twisted or spasmodic torticollis. This involuntary movement can be aggravated by emotional stress, or when the spirit is stimulated, or during casual exercise, and is relieved when completely quiet, and stops when falling asleep.
