What are symptoms of Pelizaeus-Merzbacher?
Symptoms can begin in infancy and include problems with feeding, poor weight gain and slow growth, high-pitched breathing caused by an obstructed airway (stridor), nystagmus, progressive speech difficulties (dysarthria), severe ataxia, hypotonia, and seizures.
What causes Pelizaeus-Merzbacher?
Pelizaeus-Merzbacher disease is a disorder that affects the brain and spinal cord. It is a type of leukodystrophy and is characterized by problems with coordination, motor skills, and learning. It is caused by an inability to form myelin due to genetic changes in the PLP1 gene.
Is there treatment for Pelizaeus-Merzbacher?
There is no cure for Pelizaeus-Merzbacher disease, nor is there a standard course of treatment. Treatment is symptomatic and supportive and may include medication for movement disorders. The prognosis for those with the severe forms of Pelizaeus-Merzbacher disease is poor, with progressive deterioration until death.
How long do kids with PMD live?
Life expectancy of a few years to teen years. If symptoms appear a month or later after birth (nystagmus, hypotonia), then it is most likely the classic type of PMD. Life expectancy could extend to their 40s. In order for PMD to be accurately diagnosed, a brain MRI and a genetic blood test are done.
Is PMD curable?
Although there is currently no cure for PMD, it is treatable. With proactive, comprehensive medical care the symptoms of PMD can be well-managed to give the individual the best quality of life possible.
How many people have PMD?
PMD is a rare disorder. Its prevalence in the general population is unknown but estimated as approximately 1 in 100,000 in the USA.
What are the symptoms of PMD?
The signs of connatal PMD are present at birth or are observed during the first few weeks of life. This form of the disorder is characterized by weakness, spasticity, high-pitched sound when breathing (stridor), nystagmus, and seizures.
What are the different forms of Pelizaeus–Merzbacher disease?
The several forms of Pelizaeus–Merzbacher disease include classic, congenital, transitional, and adult variants. Milder mutations of the PLP1 gene that mainly cause leg weakness and spasticity, with little or no cerebral involvement, are classified as spastic paraplegia 2 (SPG2).
What are the goals of research on Pelizaeus-Merzbacher disease?
The goals of this research are to increase scientific understanding of these disorders and to find ways to prevent, treat, and ultimately cure them. Pelizaeus-Merzbacher disease (PMD) is a rare, progressive, degenerative central nervous system disorder in which coordination, motor abilities, and intellectual function deteriorate.
What are the treatment options for Pelizaeus-Merzbacher disease (pm)?
There is no cure for Pelizaeus-Merzbacher disease, nor is there a standard course of treatment. [2] [4] Management typically involves a multidisciplinary team made of specialists in neurology, physical medicine, orthopedics, pulmonary medicine, and gastroenterology.
