[Differential diagnostic aspects of progressive spastic paraplegia in adults with emphasis on neurometabolic diseases]. / Differentialdiagnostische Aspekte der progredienten spastischen Paraparese beim Erwachsenen mit Betonung neurometabolischer Erkrankungen.

The differential diagnosis of a progressive spastic paraparesis in the young adult is broad and includes rare neuro-metabolic diseases like cerebro-tendinous xanthomatosis, adrenomyeloneuropathy and hypovitaminosis. Their clinical presentation as well as the result of paraclinical examinations can be similar to those of multiple sclerosis. The early recognition of these diseases is important, because a dietary regimen may reduce the severity and progression of symptoms and signs and genetic counselling can be important. The relevant biochemical examinations for their detection are discussed. These neuro-metabolic diseases have to be differentiated from other neuro-degenerative diseases like amyotrophic lateral sclerosis and hereditary spastic paraplegias.
