In a retrospective case-matched study from Taiwan published in Neurology, persons with bipolar disorder (BPD) were almost 7 times more likely to develop Parkinson’s disease (PD). Incidence of PD in people with BPD was 0.7% vs 0.1% for those without BPD (HR 6.95; 95% CI: 6.95-8.02). Onset of PD earlier in those with BPD (64 vs 73 years; P < .001). For those with BPD, the risk of PD increased with the number of hospitalizations for psychiatric symptoms. These findings suggest a diagnosis of BPD with other findings of PD risk factors (eg, positive dopamine transporter [DaT] scan...
In a phase 2b/3 clinical trial (NCT02848326), adults treated with atogepant (Allergan, Madison, NJ) had greater reduction from baseline in monthly migraine days (MMD) on average, compared with those treated with placebo. No serious adverse events related to treatment occurred. Of those treated with atogepant, the frequency of treatment-emergent adverse events ranged from 57% to 66% across the treatment arms vs 49.5% for those who took placebo. Elevated ALT or AST (>3x the upper limit of normal) occurred in 10 participants (1.8%), balanced across the 6 treatment arms, including...
Treatment with inebilizumab (VielaBio, Gaithersburg, MD) reduced relapses of neuromyelitis optica spectrum disorder (NMOSD) by 77% after 28 weeks of treatment. Response to treatment with inebilizumab for NMOSD was safe and effective such that the trial was terminated early as it was deemed unethical not to treat participants in the placebo arm of a phase 3 trial (NCT02200770). After this judgement was made, all participants in the placebo arm began receiving inebilizumab on an open-label extension basis. Treatment with inebilizumab also reduced worsening from baseline score on...
