Objective: To investigate the risk factors of motor complications in female patients with Parkinson's disease (PD) and the correlation between the occurrence of motor complications and sex hormone levels.

Methods: According to the occurrence and types of motor complications, 103 female PD patients were divided into two groups: patients with or without the wearing-off phenomenon, patients with or without dyskinesia. Binary logistic regression analysis was performed respectively to screen for the risk factors of the wearing-off phenomenon and dyskinesia in female PD patients.

Results: Among 103 female PD patients, 44 (42.72%) had motor complications. Patients with the wearing-off phenomenon and patients with dyskinesia had higher prolactin levels than patients without the wearing-off phenomenon and patients without dyskinesia, respectively. However, the difference was no longer significant when the two groups were corrected for multiple comparisons (P < 0.0028). Multivariate analysis found that younger age at onset and higher Hoehn-Yahr (H&Y) stage were identified as independent risk factors for the wearing-off phenomenon and younger age of onset was an independent risk factor for dyskinesia in female PD patients (P < 0.05).

Conclusion: Female PD patients have a higher incidence of motor complications. Younger age of onset and higher H&Y stage were the risk factors of the wearing-off phenomenon, and younger onset age was the risk factor of dyskinesia in female PD patients. There may be a certain correlation between the occurrence of motor complications and sex hormone levels in female PD patients, which requires further verification.

Background: Neurodegenerative diseases (NGD) encompass a range of progressive neurological conditions, such as Alzheimer's disease (AD) and Parkinson's disease (PD), characterised by the gradual deterioration of neuronal structure and function. This degeneration manifests as cognitive decline, movement impairment, and dementia. Our focus in this investigation is on PD, a neurodegenerative disorder characterized by the loss of dopamine-producing neurons in the brain, leading to motor disturbances.

We report a rare case of a missed intracavernous internal carotid artery dissecting aneurysm occurring as a complication of the base of skull fracture with severe brain injury causing acute cavernous sinus syndrome with permanent vision loss. A 31-year-old Myanmar lady had an alleged motor vehicle accident and suffered severe traumatic brain injury with multiple intracranial bleeds, multiple facial bone and base of skull fractures, and limb fractures. At one week post-trauma, she had severe right eye proptosis with vision loss, ophthalmoplegia, chemosis, and high intraocular pressure.

Background: Catechol-O-methyl transferase (COMT) inhibitors are routinely used to manage motor fluctuations in Parkinson's disease (PD). We assessed the effect of opicapone on motor symptom severity in levodopa-treated patients without motor complications.

Methods: This was a randomized, double-blind, 24-week, placebo-controlled study of opicapone 50 mg as adjunct to levodopa (NCT04978597).

BACKGROUND Swallowing is a complex behavior involving the musculoskeletal system and higher-order brain functions. We investigated the effects of different modalities of repetitive transcranial magnetic stimulation (rTMS) on the unaffected hemisphere and observed correlation between suprahyoid muscle activity and cortical activation in unilateral stroke patients when swallowing saliva, based on functional near-infrared spectroscopy (fNIRS). MATERIAL AND METHODS From November 2022 to March 2023, twenty-five patients with unilateral stroke were screened using computed tomography or magnetic resonance imaging and identified via a video fluoroscopic swallow study.
