The impact of the nocturnal disabilities of Parkinson's disease on caregivers' burden: implications for interventions.
Parkinson's disease (PD) imposes a burden on those who care for the person afflicted. The objective of this study was to assess and analyze the main determinants of caregivers' burden, especially the nocturnal manifestations of PD. This multi-center, national, cross-sectional study included 89 patient-caregiver pairs. ⋯ Moderate association was found on MPDSS item 14 (r = 0.38) and NADCS akinesia score (r = 0.37). Patients' anxiety, nocturnal akinesia and the feeling of tiredness and sleepiness upon awakening in the morning were independent predictors of caregivers' burden (adjusted R2 = 0.46). Based on these findings, treatment of early mood symptoms of the patients and caregivers at risk may be helpful for the effective management of PD and it is also important to have well-designed psycho-educational and multicomponent interventions in the community for caregivers of persons with PD.

Glutamate is the major excitatory neurotransmitter of the Central Nervous System (CNS), and it is crucially needed for numerous key neuronal functions. Yet, excess glutamate causes massive neuronal death and brain damage by excitotoxicity--detrimental over activation of glutamate receptors. Glutamate-mediated excitotoxicity is the main pathological process taking place in many types of acute and chronic CNS diseases and injuries. ⋯ Taken together, all these evidences show that anti-glutamate receptor antibodies are much more frequent among various neurological diseases than ever realized before, and that they are very detrimental to the nervous system. As such, they call for diagnosis, therapeutic removal or silencing and future studies. What we have learned by now about the broad family of anti-glutamate receptor antibodies is so exciting, novel, unique and important, that it makes all future efforts worthy and essential.
