Mitochondrial diseases are heterogeneous and multifaceted, and can present at any age. [bcmj.org]

Diagnostic Challenges: There are many different clinical presentations for mitochondrial disease and mitochondrial disease may mimic many other conditions. [newcastle-mitochondria.com]

In the present study, there were 8 male and 6 female patients. The mean age of presentation was 24.42+11.18 years (range 4-40 years). [neurologyindia.com]

The presentation is usually insidious as in T2D, however around 20% of cases present acutely, even with ketoacidosis in a small proportion. [diapedia.org]

• Proximal Muscle Weakness

  The mitochondrial diseases may present in young adulthood and manifest with proximal muscle weakness, sometimes with severe involvement of the muscles that move the eyes (external ophthalmoplegia). [humpath.com]

  Symmetrical proximal muscle weakness with absence of sensory symptoms (paraesthesia). Atrophy of muscles (and reduced reflexes) occurs late with myopathies (early with neuropathy). [patient.info]

  The myopathy was rated mild if the patient had only myalgia and minimal muscle weakness, moderate if proximal muscle strength was rated 4+/5 on the Medical Research Council (MRC) scale (the scale ranges from 0 to 5, with 5 denoting normal strength) 21 [nejm.org]

The latter are usually readily excluded during the metabolic workup by clinical presentation, MRI, and biochemical investigations. [mitosoc.org]

As far as we know - the only treatment is stopping statins if they are bringing out symptoms and considering CoQ10 supplementation. jpmorgan: For mitochondrial disease treatment, the levels of vitamins and minerals taken are very high. [my.clevelandclinic.org]

[…] expression of mitochondrial proteins as a radical treatment for mtDNA mutation load. [en.wikipedia.org]

What is the prognosis with treatment? There is no proved treatment for mitochondrial disorders. The prognosis is unpredictable without treatment; this is why natural history studies for each condition are so important. [childneurologyfoundation.org]

A few patients improve on treatment with specific vitamins such as ubiquinone, but most do not. [mda.org.au]

The diet, levels of physical activity and dietary supplements recommended for treatment will vary depending on the myopathy. [rheumatology.org]

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]

Hence, the illness tends to progress more quickly than in adults and with a poorer prognosis. The older a person is when symptoms occur, the slower the progression and the better the prognosis. [amdf.org.au]

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]

Prognosis This depends on the specific diagnosis. The primary disorders are incurable conditions with varied prognosis. Secondary myopathy may be corrected by treating the underlying cause. [patient.info]

It is true though that the muscle biopsy results do not directly affect our ability to provide prognosis or choose treatment if a person has mitochondrial disease. [my.clevelandclinic.org]

Certain differences between the "coupling" data of Luft and ours and certain aspects of the "coupling" response to chloramphenicol remain unexplained, as does the ultimate etiology of the mitochondrial disease. FULL TEXT [annals.org]

Studies using larger numbers of patients with defined diseases of particular genetic etiologies will enhance the diagnostic value of MRS results. [mitosoc.org]

All the cases were investigated to rule out other etiologies according to their clinical presentations and to confirm the diagnosis of mitochondrial cytopathy. [neurologyindia.com]

Etiologic factors in cricopharyngeal dysphagia I. Central nervous system disease. Cerebrovascular accident ; bulbar polio ; cerebral palsy ; multiple sclerosis ; amyotrophic lateral sclerosis ; brain stem tumor... II. Peripheral nerve disease. [hon.ch]

Epidemiology These are all relatively uncommon diseases: Duchenne muscular dystrophy is easily the most common childhood-onset muscular dystrophy and affects 1 in 3,300 boys. [ 6 ] The prevalence of Duchenne muscular dystrophy is 63 cases per million. [patient.info]

Although the exact pathophysiology of statin-induced myopathies is not fully understood, important mitochondrial cofactors arise from the cholesterol biosynthesis pathway, such as CoQ10. [michaelrucker.com]

Prevention Genetic counselling is, in some of the most common myopathies such as Duchenne muscular dystrophy, the only intervention that can prevent disease. In general: Give genetic counselling early. [patient.info]
