Abstract PDF: Objective
This study aimed to characterize the phenotypic spectrum and therapeutic outcomes of patients of Indian and Asian origin with DYT-TOR1A.
Methods
A retrospective chart review of patients with genetically confirmed DYT-TOR1A (c.907_909delGAG; p.Glu303del variant) from a tertiary care center in India.
Results
Twelve patients (11 males, 91.7%) with a median age at disease onset of 10.5 years (range, 8–17 years) and a disease duration of 5 years (range, 2 months–31 years) were included. All patients had an isolated and progressive dystonia phenotype. Eight patients (66.7%) had a disease onset in childhood, and limb involvement at disease onset was noted in 10 (83.3%) patients. Five patients (41.7%) underwent bilateral globus pallidus internus deep brain stimulation within a median duration of 4 years (range, 2.5–6.5 years) from onset, with significant improvement.
Conclusion
This Indian patient cohort showed a strong male predominance and consistent early involvement of the upper limbs. A shorter disease course accompanied by greater severity highlights the need for early recognition and potential surgical intervention.

Objective
Willingness to undergo deep brain stimulation (DBS) among patients with Parkinson’s disease (PD) and their overall satisfaction with the procedure is highly dependent upon expectations, which are based on the core concepts of knowledge, attitude and perceptions. The present study aims to evaluate these factors in patients and caregivers with PD from a single tertiary care hospital in India.
Methods
A structured questionnaire designed to assess the knowledge, attitude and perceptions about DBS in PD was administered to 400 patients with PD and their caregivers.
Results
A very small proportion of patients and caregivers were aware of DBS. Even those who claimed to be aware of DBS were inadequately informed and had incorrect knowledge, which led to wrong attitudes and perceptions.
Conclusion
There are very significant knowledge gaps and misconceptions regarding DBS among patients with PD and caregivers. Adequate and appropriate education is necessary to clarify these misconceptions to avoid the development of unrealistic expectations and poor satisfaction.

Abstract PDF

Objective
The novel coronavirus disease (COVID-19) pandemic and public health measures to control it have resulted in unique challenges in the management of patients with deep brain stimulation (DBS). We report our experience with the management of acute worsening of symptoms due to battery exhaustion in 3 patients with DBS.
Methods
Patients with DBS for movement disorders who visited the emergency room due to battery exhaustion during the nationwide lockdown from April to May 2020 were included.
Results
Two patients with subthalamic nucleus-DBS for Parkinson’s disease (PD) and one with globus pallidus interna-DBS for generalized dystonia presented with acute worsening of symptoms due to battery exhaustion. Urgent battery replacement was performed in both patients with PD. The patient with generalized dystonia was managed with medication adjustment as he chose to defer battery replacement.
Conclusion
DBS battery replacement can be an emergency. Decisions regarding DBS battery replacement should be individualized during this COVID-19 pandemic.
