Familial Olivopontocerebellar Atrophy (FOPCA) is a rare genetic disorder that affects the brain's coordination and movement. While commonly referred to as FOPCA, this condition can also be described using several synonyms. One of the most frequently-used alternatives is autosomal dominant cerebellar ataxia type III (ADCA III). This name highlights the condition's hereditary nature and its impact on the cerebellum, which controls balance and coordination. Other synonymous terms include Olivopontocerebellar Atrophy Type III and Holmes type spinocerebellar degeneration. Although these terms may differ slightly, they all describe the same debilitating condition and aid in better understanding its symptoms, genetic implications, and potential treatments.
