“…The basal ganglia control voluntary motor activity primarily by regulating the motor and premotor cortex [ 2 ]. Although the occurrence of motor disturbance following basal ganglia infarction is well recognized, the rehabilitation of motor function has not been serially assessed with longitudinal fMRI [ 3 – 5 ]. This assessment can help in understanding the mechanism of functional recovery, in addition to providing potentially useful metrics for monitoring the efficacy of rehabilitation therapy in these patients.…”

We used functional fMRI to study the brain activation during active finger movements at different time points during the recovery phase following basal ganglia infarction. Four hemiplegic patients with basal ganglia infarction were serially evaluated at different time points spanning the acute and chronic phase using fMRI. To evaluate motor recovery, the patients were asked to perform functional tasks arranged in a block design manner with their hand. On follow-up (chronic phase), three patients achieved significant recovery of motor function of affected limbs. Activation of bilateral sensorimotor cortex (SMC) was observed in two of these patients, while activation of cerebellum was observed in all patients. No remarkable recovery of motor function was noted in one patient with left basal ganglia infarction. In this patient, the activation domain was located in SMC of both sides in acute phase and in ipsilateral SMC in chronic phase. Contralateral SMC appears to be involved in the functional rehabilitation following basal ganglia infarction. The cerebellum may act as an intermediary during functional recovery following basal ganglia infarction. The activation domain associated with active finger movement may be bilateral in acute phase; one patient was ipsilateral in the chronic stage.

“…As the name itself suggests, it involves one side of the body, usually the arm, leg, proximal in most cases, with facial involvement in approximately half of the cases. [ 1 2 3 4 5 ] Symptoms occur with activity, decrease with rest and disappear with sleep. [ 2 ] Chorea and hemiballismus may present as a spectrum of disease with hemiballismus often evolving into hemichorea, so the term hemichorea-hemiballismus is sometimes used.…”

“…Hemiballismus is a rare movement disorder associated with involuntary, large-amplitude, flinging movements of the limbs. [ 1 2 3 4 5 ] While it has been classically described with lesions of the subthalamic nucleus (STN), more and more lesions outside the STN have been reported recently. [ 1 3 4 ] Compared to those arising from STN, cortical hemiballismus is usually less severe with a good long-term prognosis.…”

Context:Hemiballismus is characterized by involuntary, irregular, large amplitude, and violent flinging movements of limbs. Stroke (middle and posterior cerebral artery) remains the most common etiology with 2/3 being lacunar. Lesions outside the substantia niagra (STN) can cause hemiballism, and only a minority by STN lesions, unlike the classical belief. Compared to those arising from STN, cortical hemiballismus is usually less severe with a good prognosis.Case Report:A 61-year-old man presented with sudden onset involuntary flinging movements of his right upper extremity accompanied by numbness and tingling. Past medical history was significant for stroke 2 years back with no residual deficits. Vitals signs were blood pressure of 165/84 mm Hg, and heart rate - 82 beats/min. Irregular, arrhythmic, jerky flinging movement, and decreased sensation to light touch in right upper extremity was noted. Magnetic resonance imaging of the brain revealed acute posterior left parietal lobe infarction. He was treated with aspirin and atorvastatin. Thrombolytic therapy was offered but declined. The movements resolved spontaneously over the next 2 days. No further episodes occurred at 3-month follow-up.Conclusion:Lesions affecting various areas outside the STN can cause hemiballism and usually carries a good prognosis with spontaneous resolution. Acute thrombolytic therapy may be considered on an individual basis. Treatment with antipsychotics can be useful for severe and recurring symptoms.

“…Movement abnormalities are three times more common after subcortical strokes than after cortical strokes, with the basal ganglia (44%) and thalamus (33%) being most frequently affected. Movement difficulties following a stroke are uncommonly associated with cerebellar abnormalities that affect it alone (Hao et al, 2015;Tater & Sanjay, 2021). examinations (Defebvre & Krystkowiak, 2016).…”

Introduction: Movement disorders can be separated into hypokinetic disorders, which cause paucity or slowness (bradykinesia), and hyperkinetic disorders, which cause excessive, aberrant involuntary motions Less than 5% of individuals with cerebrovascular diseases presented with involuntary movement. It might be difficult to identify and diagnose hyperkinetic disorders. Case: We describe a 56-year-old man who arrived at the hospital with 5 hours of abrupt, uncontrollable movement in his right upper and lower limbs. A complete neurological evaluation revealed an uncontrolled, nonrhythmic, non-patterned, aimless, and frequently jerky movement of the right upper and lower limbs with a ballistic component that varies in amplitude and frequency. Higher psychic function and cranial nerves were normal. Chest radiography, electrocardiography were normal. Hemorrhage was ruled out by a brain non-contrast CT scan at admission. The patient was diagnosed with hemichorea-hemiballism caused by an ischemic stroke based on clinical evidence of a sudden neurological deficit of aberrant involuntary movement. After receiving medical treatment for five days, the involuntary motions stopped occurring without causing any more neurological abnormalities or weakening. Discussion: Ischemic stroke diagnosis relied on skilled clinical assessment without explicit neuroimaging. While hemiballismus is characterized by violent irregular flinging movements of the limbs brought on by contractions of the proximal muscles, hemichorea consists of continuous random, anarchic, and jerking movements involving both the distal and proximal muscles (though it is occasionally localized more distally). Conclusion : Hyperkinetic movement disorders are a rare presentation of stroke. The pathophysiology of these abnormal movements remains uncertain. Even though they are uncommon, following a stroke, aberrant motions can occur suddenly or develop gradually. Hemichorea-hemiballismus with abrupt onset should be treated as an acute stroke unless proven other causes
