The main neurological symptoms of mitochondrial disease include developmental delays, mental retardation or regression, dementia, seizures (especially atypical or refractory ones), coma, neuro-psychiatric disturbances, atypical cerebral palsy, myoclonus [amdf.org.au]

Movement disorders have been described due to mitochondrial abnormalities. [19], [20] Dystonia has been the most frequent movement disorder [20] besides myoclonus, chorea, athetosis, and tremors. [neurologyindia.com]

In pediatric mitochondrial disease, a broad spectrum of findings may be present, including lethargy, hypotonia, failure to thrive, seizures, cardiomyopathy, deafness, blindness, movement disorder, and lactic acidosis. [bcmj.org]

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]

All the patients had proximal muscle weakness, myalgia, a two- to six-fold elevation of the serum creatine kinase level (measured by an enzymatic reaction), and evidence of myopathic changes in the electromyogram, all of gradual onset, as previously reported [nejm.org]

Neurological manifestations of mitochondrial cytopathies comprise of multineuraxial involvement with raised serum lactic acid and positive muscle biopsy for mitochondrial abnormalities confirmed by genetic analysis for mitochondrial DNA/nuclear DNA mutation [neurologyindia.com]

Neurological manifestations include encephalopathy, cognitive regression, seizures, and peripheral neuropathy. Involvement of skeletal and cardiac muscle is frequent, while endocrine system manifestations commonly include diabetes mellitus. [bcmj.org]

Seizures began at 21/2 years with arm stiffness, then clusters of right-sided facial twitching and weakness, then staring spells, eye twitching, and myoclonic jerks. [bcmj.org]

His generalised tonic clonic seizures were controlled, although brief myoclonic jerks were persisting. MELAS was first described by Pavlakis et al [15] in 1984. [neurologyindia.com]
