Abstract

Maternally inherited diabetes and deafness (MIDD) is a disorder characterized by the occurrence of diabetes mellitus and hearing impairment at a young age, caused by point mutations in mitochondrial DNA. MIDD can be accompanied by various neurological symptoms. In this patient, memory impairment and ataxia were the predominant neurological symptoms. Herein, we report MIDD patients with the m.3243A>G mutation who present with cognitive decline and gait disturbance at the age of 59.
