Document Summary

The disorder i will be presenting is called troyer syndrome. It is a more complicated form among thirty different types of hereditary spastic paraplegias which is differentiated by a progressive muscle stiffness and a development of paralysis in the lower limbs. It is a genetically distinct neurological disorder and occurs in the central and peripheral nervous system. This is an autosomal recessive disorder in which both parents must carry the gene to pass it on. The first is referred to as the pure form in which a doctor would find signs of spasticity in the lower limbs including stiffness, brisk reflexes, and plantars. The second classification is called the complex form which involves the lower limbs as well as the upper limbs therefore affecting the structure and function of the brain and peripheral nervous system such as touch, pain, heat and sound. This disorder is commonly associated with progressive spasticity in the lower limbs, short stature, hyper-reflexia, and bladder issues.
