Vagus nerve stimulation (VNS) delivered via the implantable Neurocybernetic Prosthesis (NCP) from LivaNova PLC (London, United Kingdon) is an established treatment option for patients with intractable epilepsy. It has also emerged as a novel adjunct in the management of patients…

Infusion Therapy for Movement Disorders

Review of the Current Knowledge Base of the Topic Direct intracerebral infusion of neurotrophic factors may represent a neuroprotective and neurorestorative therapeutic strategy for neurodegenerative movement disorders, most notably Parkinson’s disease (PD). A number of neurotrophins, including glial cell-line-derived neurotrophic…

Surgical Management of Hemifacial Spasm and Meige Syndrome

Hemifacial Spasm Introduction Hemifacial spasm (HFS) is a unilateral, involuntary, paroxysmal movement of facial muscles innervated by the ipsilateral facial nerve. Its characteristic features include tonic–clonic contractions and synkinesis of the muscles. These symptoms usually start from the orbicularis oculi…
