The differential involvement of adrenoceptors in challenges of different intensities

We investigated a family with optic atrophy which occurred in childhood or early adulthood plus late-onset cerebellar ataxia. The magnetic resonance imaging in the proband revealed cerebellar atrophy. The proband and her brother were homoplasmic for the most common mitochondrial DNA (mtDNA) 11778 mutation associated with Leber's hereditary optic neuropathy (LHON). This study showed further evidence that central nervous system lesions can occur in cases of LHON mtDNA mutation.
