The connatal form is the most severe form presenting, since birth, with hypotonia, nystagmus, respiratory distress, and stridor, with subsequent motor and cognitive delay and spastic quadriparesis. [orpha.net]

The congenital form has similar characteristics but presents early in infancy and features rapid disease progression. Transitional and adult subtypes have a later onset and less severe symptomatology. [hon.ch]

Treatment Edit There is no cure for PMD, nor is there a standard course of treatment. Treatment, which is symptomatic and supportive, may include medication for seizures and spasticity. [psychology.wikia.com]

Prognosis PMD has a progressive course that varies depending on the phenotype. In the most moderate forms, life expectancy is quite long and the disease progresses slowly after adolescence. [orpha.net]

The prognosis for those with Pelizaeus-Merzbacher disease is highly variable, with children with the most severe form (so-called connatal) usually not surviving to adolescence, but survival into the sixth or even seventh decades is possible, especially [psychology.wikia.com]

Regular evaluations by physical medicine and rehabilitation, orthopedic, developmental, and neurological specialists should be made to ensure optimal therapy and educational resources. [ citation needed ] Prognosis is highly variable: patients with the [en.wikipedia.org]

Etiology PMD is an X-linked disorder due to mutations or dosage alterations of the PLP1 gene (Xq22) that cause hypomyelination of the central nervous system (CNS). PMD is allelic to SPG2 which is also due to PLP1 mutations. [orpha.net]
