Spinal Muscular Atrophy

Spinal Muscular Atrophy Spinal healthy atrophy or SMA for short is a neuromuscular sickness. SMA represents a meeting of autosomal- recessive rowdyisms, lead to muscle weakness and atrophy. This disorder is common and is passed on genetically to children by their p atomic number 18nts. You cannot “ contract” Spinal Muscular Atrophy by being well-nigh someone who has it. It is caused by progressive alloy of the prior schnozzle cells of the spinal anesthesia cord. (Hockenberry & Wilson, 2007, p. 1) SMA is a genetic disease that affects primarily children. SMA is the “ bet on almost common…inherited disorder after cystic fibrosis”. One fall out of fourty people is a carrier of this recessive gene. SMA affects the a child’s muscular development, and the severity depends on what ‘type’ of SMA the child has. The brain is not known to be affected, and they have been tested to have at least fair to above average intelligence . There argon four “ fibres” of spinal muscular atrophy, Type 1, 2, 3, and 4. The earlier the symptoms are noticed normally indicates the SMA is more severe. Type 1 is the most severe out of all the types of SMA, and affects the child while take over in the womb or shortly after birth. Type 4 is the least severe, affecting adults. (Piepers, 2008) SMA was first described in the category of 1890, by Guido Werdnig , a physician from the University of Vienna, during a lecture. It was not enormous afterwards that a professor from Hiedleberg University, named Johann Hoffman wrote a musical estimation describing a syndrome of a patient exhibiting atrophy, muscle weakness, and death during the soonest childhood period of siblings with genetically normal parents. Upon doing an autopsy on the children both physicians found severe atrophy of the ventral give rise of the spinal cord and loss of motor neurons in the preceding horn cells. Hoffman called the syndrome spinale muskelatrophie ( spinal muscular atrophy).(!
