Abstract
BACKGROUND AND IMPORTANCE: Primary generalized dystonia (PGD) is a genetic form of dystonia that frequently displays pharmacological resistance and progresses quickly after onset. Deep brain stimulation (DBS) has been used successfully to treat refractory dystonia, specifically globus pallidus interna (GPi) DBS for DYT1-positive PGD patients. Long-term follow-up of the safety and efficacy falls short of the longevity seen in other diseases treated with DBS.
CASE PRESENTATION: A male patient presented for neurosurgical evaluation with scapular winging, hand contractures, and violent truncal spasms, which forced him to be bedridden. After failing conservative therapy, the 18-yr-old patient was implanted with bilateral GPi-DBS. DBS parameter adjustments were made primarily within the first 3 yr after implantation, with nominal changes thereafter. Initial settings were contact of 3 + 0-, amplitude of 4.9 V, frequency of 185 Hz, and pulse width of 270 mu sec on the left and 3 + 0-, 2.8 V, 185 Hz, and 120 mu sec on the right. Current settings are 3 + 2 + 1-, 5.2 V, 130 Hz, 330 mu sec on the left and 3 + 0-, 3.5 V, 185 Hz, and 180 mu sec on the right and have been relatively unchanged in the past 4 yr. Unified dystonia rating scale scores reveal a significant decrease in dystonic symptoms.
CONCLUSION: While prior reports have shown that GPi-DBS is effective for dystonia, this is the first with 15 yr of long-term follow-up showing disease stabilization, suggesting that stimulation is efficacious and can potentially prevent disease progression. This repor reaffirms previous reports that recommend early surgical intervention before the onset of permanent musculoskeletal deficits.
