脊髓性肌肉萎缩症第一型(重度SMA typeⅠ):属于严重型之脊髓性肌肉萎缩症(Werdning-Hoffmann Disease)在出生六个月内会出现症状,病患严重无力且呈现四肢类似青蛙状;严重肌肉张力减退;颈部控制不良、吞咽及呼吸困难合并哭声无力。一般在两岁前就会因呼吸衰竭而死亡。 脊髓性肌肉萎缩症第二型(中度SMA typeⅡ):属于中度型...
Type 1 spinal muscular atrophy (SMA), also called infantile-onset SMA or Werdnig-Hoffmann disease, is the most common form of SMA, accounting for about 60% of cases.SMA is a rare genetic disease characterized by the progressive loss of motor neurons, the nerve cells that control voluntary ...
SMA type 1 life expectancyAlso known as Werdnig-Hoffmann disease, SMA type 1 is usually diagnosed in the first six months of life. It is the most common form of SMA.Without medical support, SMA type 1 life expectancy is short, with infants having an average lifespan of about 2 years ...

For both types of SMA, statistically significant negative correlations were found between the elapsed interval from the onset of the disease to the initiation of treatment and upper motor acquisitions (type 1: p < 0.0001, r = -0.713, type 2: p<0.001, r = -0.560...

Swallowing problems common in untreated SMA type 1 infants Profound deficits in mechanisms essential for swallowing are common among untreated infants with spinal muscular atrophy (SMA) type 1, according to a natural history study. While nearly all the babies could initiate the swallowing process, pro...
Disease Department: Neurology SMA：婴幼⼉遗传病头号杀⼿ 8⽉7⽇是「国际脊髓性肌萎缩症（SMA）关爱⽇」。1891年，奥地利神经病学家Guido Werdnig观察到⼀对婴⼉兄弟，他们在10个⽉⼤时开始变得 虚弱，这是SMA⾸次被发现和报道。脊髓性肌萎缩症（SMA）是⼀种罕见的遗传性神经肌⾁疾病，表现...
Type 1 Also called Werdnig-Hoffmann disease, this is a severe form of SMA. It’s diagnosed right at birth or up to 6 months of age. Muscle weakness becomes worse very quickly. Your child won’t be able to sit or stand without treatment. ...
By medical definition,SMA is an autosomal recessive genetic disease.This genetic defect results in the absence of a specific type of protein,one that fuels motor neurons responsible for transmitting signals from the brain to muscle junctions.Fo...
