Is speech function lateralised in the basal ganglia? Evidence from de novo Parkinson's disease.
Research on the possible influence of lateralised basal ganglia dysfunction on speech in Parkinson's disease is scarce. This study aimed to compare speech in de-novo, drug-naive patients with Parkinson's disease (PD) with asymmetric nigral dopaminergic dysfunction, predominantly in either the right or left hemisphere. ⋯ Our data support the crucial role of DAT availability in the left putamen in speech. This finding might provide important clues for managing speech following deep brain stimulation.

Observational StudyEpidemiology of myasthenia gravis in Denmark, Finland and Sweden: a population-based observational study.
Incidence and prevalence rates of myasthenia gravis (MG) vary considerably across studies, and mortality risk is rarely addressed. We examined the prevalence and incidence rates, mortality and factors associated with mortality with MG. ⋯ This population-based study from three Nordic countries highlights the need for improved care of patients with MG, especially young women.

Contribution of basal ganglia activity to REM sleep disorder in Parkinson's disease.
Rapid eye movement (REM) sleep behaviour disorder (RBD) is one of the most common sleep problems and represents a key prodromal marker in Parkinson's disease (PD). It remains unclear whether and how basal ganglia nuclei, structures that are directly involved in the pathology of PD, are implicated in the occurrence of RBD. ⋯ These findings support that basal ganglia activities are associated with if not directly contribute to the occurrence of RBD in PD. Our study expands the understanding of the role basal ganglia played in RBD and may foster improved therapies for RBD by interrupting the basal ganglia-muscular communication during REM sleep in PD.

Randomized Controlled TrialDoes stereotactic thrombolysis with alteplase for intracerebral haemorrhage alter intraventricular haematoma volume? A secondary analysis of the MISTIE-III trial.
Stereotactic thrombolysis reduces intracerebral haemorrhage (ICH) volume in patients with spontaneous ICH. Whether intrahaematomal alteplase administration is associated with a change in intraventricular haemorrhage volume (deltaIVH) and functional outcomes is unknown. ⋯ Alteplase delivered into the ICH in MISTIE-III subjects with IVH was associated with a small reduction in IVH volume. This reduction did not translate into a significant benefit in mortality or functional outcomes at 365 days.
