Post-Operative Supplementary Motor Area Syndrome
Rationale: Surgical removal of the lesions involving the supplementary motor area, results in immediate motor and speech deficits, which in most cases are reversible. Aim: Extent of removal of the supplementary motor area influences the post-operative deficits. Patients and Methods: 12 cases are included in this study, representing lesions involving the supplementary motor area by intra-axial g...
متن کاملBilateral supplementary motor area syndrome causing akinetic mutism following parasagittal meningioma resection
The supplementary motor area (SMA-proper) is important for the programming and execution of motor, speech, and other elaborative functions. Unilateral SMA syndrome is well described. We present two patients who underwent resection of a large parasagittal meningioma in proximity to the SMA-proper in both hemispheres. Following surgery, these patients developed akinetic mutism; the maximal clinic...
متن کاملIntraoperative Motor Symptoms during Brain Tumor Resection in the Supplementary Motor Area (SMA) without Positive Mapping during Awake Surgery
Awake surgery could be a useful modality for lesions locating in close proximity to the eloquent areas including primary motor cortex and pyramidal tract. In case with supplementary motor area (SMA) lesion, we often encounter with intraoperative motor symptoms during awake surgery even in area without positive mapping. Although the usual recovery of the SMA syndrome has been well documented, ra...
متن کاملLower Motor Neuron Findings after Upper Motor Neuron Injury: Insights from Postoperative Supplementary Motor Area Syndrome
Hypertonia and hyperreflexia are classically described responses to upper motor neuron injury. However, acute hypotonia and areflexia with motor deficit are hallmark findings after many central nervous system insults such as acute stroke and spinal shock. Historic theories to explain these contradictory findings have implicated a number of potential mechanisms mostly relying on the loss of desc...
متن کاملSurgical treatment of supplementary motor area lesions.
Different portions of the SMA appear to be engaged by different types of neurological functions. It is important to identify the functional activation of SMA in terms of planning the surgical strategy. Our unpublished data from M.D. Anderson suggest that resection of the site of SMA activation based on fMRI is an important parameter for predicting the postoperative neurological deficit. Also, p...
