Gerstmann-Straussler-Schenker syndrome is an autosomal dominant prion disease that begins in middle age.
Epidemiology
Gerstmann-Straussler-Schenker syndrome is common and is similar to Creutzfeldt-Jakob disease, but the incidence of this syndrome is approximately 100 times lower than that of Creutzfeldt-Jakob disease. The disease develops at a younger age (40 years compared to 60), and the average life expectancy after onset of the disease is longer than that of Creutzfeldt-Jakob disease (5 years compared to 6 months).
Symptoms Herstmann-Straussler-Schenker syndrome.
Patients develop cerebellar ataxia, dysarthria, and nystagmus. Gaze paresis, deafness, dementia, hyporeflexia, and abnormal plantar reflexes may occur. Myoclonic seizures are much less common than in Creutzfeldt-Jakob disease. In the presence of characteristic symptoms and a family history in young people (under 45 years), Gerstmann-Straussler-Schenker syndrome is more likely.
