Dentatorubral-pallidoluysian atrophy (DRPLA) is a progressive brain disorder that causes involuntary movements; mental and emotional problems; and a decline in thinking ability. The average age of onset of DRPLA is 30 years, but the condition can appear anytime from infancy to mid-adulthood. Specific signs and symptoms may differ among affected individuals and sometimes affects children and adults differently. DRPLA is caused by a mutation in the ATN1 gene and is inherited in an autosomal dominant manner.[1] Treatment is symptomatic and supportive.[2]
