2021年3月24日 · SMA Syndrome stands for Supplementary Motor Area Syndrome. It is a temporary neurosurgical condition first documented in 1977 and arises from damage to the supplementary motor area of the brain. It occurs in 26-100% of surgeries that take place in one of the two supplementary motor areas.

The supplementary motor area (SMA) syndrome is a frequently encountered clinical phenomenon associated with surgery of the dorsomedial prefrontal lobe. The region has a known motor sequencing function and the dominant pre-SMA specifically is associated with more complex language functions; the SMA i …

2024年7月30日 · Spinal muscular atrophy (SMA) refers to a group of hereditary diseases which affect motor neurons. Motor neurons are specialized nerve cells in the brain and spinal cord that control movement in the arms, legs, face, chest, throat, and tongue, as well as skeletal muscle activity, including muscles used for speaking, walking, swallowing, and ...

2021年5月15日 · The supplementary motor area (SMA) syndrome is a well-known phenomenon after dorsomedial prefrontal lobe surgery. The SMA region is a common hotspot for low-grade glioma (LGG) development and the syndrome is thus most frequent after …

2021年1月15日 · Brain involvement is under-investigated in spinal muscular atrophy (SMA) type 1. Neuropathological data suggest progressive brain involvement in severe forms of SMA. Impaired cognitive performances are reported in small groups with SMA type 1. Data on language in those with SMA type 1 are limited to parent reports and non-formal assessments.

2025年3月1日 · Spinal muscular atrophy (SMA) encompasses a spectrum of neuromuscular disorders characterized by the degeneration and dysfunction of SMN1 motor neurons located in the spinal cord. This condition manifests through progressive muscle atrophy, weakness, and …

2022年11月30日 · The supplementary motor area (SMA) is involved in preparing for voluntary movements carried out by the primary motor area (precentral gyrus). The SMA is located posteriorly on the medial surface of the superior frontal gyrus (sometimes referred to as the medial frontal gyrus) just anterior to the paracentral lobule 1.

Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disorder and a leading genetic cause of infantile mortality. SMA is caused by mutation or deletion of Survival Motor Neuron-1 (SMN1).

Spinal muscular atrophy (SMA) is a genetic condition that causes worsening muscle weakness. There are five subtypes, which range in severity and age of onset. There’s no cure for SMA, but certain therapies and medications can help manage symptoms. What is spinal muscular atrophy?

2024年9月30日 · SMA is a genetic disorder that affects the motor neurons in the spinal cord. These neurons are responsible for controlling voluntary muscle movement. When they don’t function properly, muscles weaken and atrophy over time. But SMA isn’t just one condition – it’s a spectrum of disorders with varying degrees of severity.
