Seasonality as a risk factor for deaths in Parkinson's disease.

Background: According to growing evidence, sleep disruption harms biological processes and circadian homeostasis. Diurnal motor symptom volatility in Parkinson's Disease (PD) has been extensively studied. Few studies examined seasonal variability in PD symptoms, some showing it and others not.

Neurogenesis and pesticides: news of no new neurons.

New hippocampal neurons are continuously generated in the adult human brain. Several studies have demonstrated that the proliferation of hippocampal cells is strongly influenced by a variety of stimuli, including pesticides exposure. These effects are particularly important because neurogenesis dysregulation could be associated with the decline of neuronal and cognitive functions and the possible development of neuropsychiatric disorders.

Discussion of the Brazilian neurologists about sudden unexpected death in epilepsy.

Objective: This study aimed to evaluate the concept of health professionals affiliated with the Brazilian League of Epilepsy on whether or not to inform patients about the risk factors related to the occurrence of sudden unexpected death in epilepsy.

Methods: A descriptive research of inquiry was conducted with direct survey on the Brazilian neurologist's view, regarding medical behavior in the health area to report or not about the risk of sudden unexpected death in epilepsy. Data collection consisted of a structured questionnaire available online.

Diagnosing SARS-CoV-2 vaccination associated rhombencephalitis requires comprehensive work-up and exclusion of differentials.

In this letter we raise several concerns regarding the interesting article by Walter and Krämer about rhomb-encephalitis as a complication two months after the vaccination with an mRNA-based SARS-CoV_2 vaccine. The causal link between the vaccination and encephalitis remained unproven, a SARS-CoV-2 infection, Bickerstaff encephalitis were not excluded, the MRI rather suggests brainstem-encephlaitis than pure rhomb-encephalitis, and the cerebro-spinal fluid was not investigated for cytokines or glial markers. Neurologists are called to make all available effort to convincingly evaluate the etiology and the pathophysiological background of an undetermined condition.
