Genetic testing showed a previously unreported de-novo YY1 nonsense variant. Because of the progression of symptoms, he underwent bilateral deep brain stimulation of the globus pallidus internus (DBS-GPi). After surgery, his condition improved. His dystonia became less severe, and his gait and speech also improved. The Burke-Fahn-Marsden motor score decreased from 100 to 50, and the disability score decreased from 20 to 14 at six months. Follow-up at four years, after implementing Brainlab software, showed further improvement in Burke-Fahn-Marsden dystonia motor score of 46 and a stable disability score of 14. Adjustments of stimulation parameters helped maintain good control of symptoms. Only one similar case treated with DBS has been reported so far.

Current guidelines recommend hospital admission for monitoring and coordination of appropriate aftercare, regardless of stroke severity. However, the clinical necessity of admitting all such patients remains uncertain. Some neurologists argue that selected low-risk patients can be discharged directly from the emergency department (ED). Given the ongoing debate and lack of high-quality evidence, we aimed to explore current practices and attitudes toward the management of patients with ischaemic stroke with minor neurological deficits in the Netherlands.</p><h3>Methods</h3><p>A national online survey was conducted to explore current variations in clinical practice regarding admission strategies for patients with ischaemic stroke.

Willingness to randomise patients into a trial evaluating admission versus ED discharge was high, with rates between 77% and 94% across cases. The majority of respondents (89%) considered a risk threshold of up to 5% for secondary deterioration acceptable to justify direct discharge from the ED.
