  • Both mechanism and treatment for pulmonary hypertension complicated with mitochondrial disease are unclear. Further study is necessary.[ncbi.nlm.nih.gov]
  • Specific treatments do not exist for the majority of mitochondrial diseases, but it is likely that the intense research that currently exists for these diseases will eventually produce effective treatment possibilities.[ncbi.nlm.nih.gov]

  • This includes PGD, which is currently offered as a clinical treatment but will not be suitable for all.[ncbi.nlm.nih.gov]


  • What is the prognosis for mitochondrial disease? The prognosis for patients with mitochondrial myopathies varies greatly, depending largely on the type of disease and the degree of involvement of various organs.[medicinenet.com]
  • The diagnostic journey may be characterized by heightened levels of uncertainty due to the delayed diagnosis and the absence of a clear prognosis, among other factors.[ncbi.nlm.nih.gov]
  • Meet other parents and patients in our closed Facebook group. back to top What is the Prognosis for Someone? The prognosis is variable. Some people live a normal life and are minimally affected; others can be severely compromised with the disease.[mitoaction.org]
  • PROGNOSIS Prognosis depends upon which disorder, which symptoms and the severity of those symptoms. Some of the conditions we thought were uniformly progressive and fatal are not (Leigh syndrome, for example).[childneurologyfoundation.org]


  • Sensory ataxic neuropathy may be the predominant and presenting manifestation of a mitochondrial disorder, and a mitochondrial etiology should be included in its differential diagnosis.[ncbi.nlm.nih.gov]
  • In both cases, no possible etiological, morphological, or genetic factors for pancreatitis were identified, including anomalous pancreaticobiliary duct.[ncbi.nlm.nih.gov]
  • OBJECTIVE: To describe the phenotype, genetic etiology, and investigation of extrapyramidal movement disorders in a large and well-defined mitochondrial disease cohort.[ncbi.nlm.nih.gov]
  • Transplant teams should be aware of mitochondrial disease as an etiology for organ-failure and consider appropriate consultation in patients without a known cause of their symptoms. Copyright 2016 Elsevier Inc. All rights reserved.[ncbi.nlm.nih.gov]
  • However, most other etiologies are due to one or more deficiencies in Complexes I – V of the respiratory chain that ultimately reduce molecular oxygen to water and synthesize ATP from ADP and inorganic phosphate.[aasmnet.org]


  • The stage has now been reached at which there is a good understanding of both the genetic basis of the disease and its epidemiology, but just how the blindness that follows from the death of cells in the optic nerve can be prevented remains to be a pharmacological[ncbi.nlm.nih.gov]
