Purpose: Patients with Guillain-Barré syndrome (GBS), especially severe cases that require treatment in intensive care units, often experience swallowing difficulties. However, the oropharyngeal function of patients with GBS not treated in intensive care units is not typically evaluated using neurophysiological techniques.
Methods: Electrophysiological techniques were used to determine dysphagia limit and sequential water swallowing values in an electromyography laboratory.
Objective: To investigate electrophysiological parameters of swallowing in all stages of Alzheimer's disease.
Methods: Forty Alzheimer's disease patients, 20 age-matched normal controls and 20 young normal controls were included. Dysphagia limit (DL) and sequential water swallowing (SWS) tests were performed.
Yawning and swallowing are fundamental physiological processes that are present from fetal stages throughout life and that involve sequential motor activities in the oropharyngo-larynx making it likely that they may share neuroanatomical pathways. We postulate that yawning and swallowing are controlled by a distributed network of brainstem regions including the central pattern generator of swallowing, and therefore spontaneous swallowing is frequently associated with spontaneous yawning. In this study, we sought to test this hypothesis by evaluating the elementary features of yawning in the facial, masseter and submental muscles, together with laryngeal movement sensor and respiratory recordings for spontaneous swallowing.

This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18 age-matched healthy adults was investigated.

The aim of this study was to determine if there is an association between valproate and reproductive abnormalities in men with bipolar disorder or if the association is unique to men with epilepsy.
Materials And Method: The study included 39 male patients aged 18-50 years with a DSM-IV diagnosis of bipolar disorder (21 on lithium monotherapy and 18 on valproate monotherapy or valproate in combination with lithium therapy) and 15 male epilepsy patients on valproate monotherapy that were evaluated in terms of reproductive hormones.
Article Synopsis
- In this study, researchers explored the relationship between intraoral trigeminal nerve activity and the EMG responses of lower facial muscles, particularly the orbicularis oris muscle, during swallowing events.
- They found that the orbicularis oculi muscle, typically not associated with swallowing, also showed synchronized activity with the swallowing process, especially during spontaneous swallowing rather than voluntary actions.
- The findings suggest that this muscle synchronization may be linked to neural pathways and could help explain certain movement disorders like craniofacial dystonias in humans.
Background: Epilepsy is accompanied by many psychiatric disorders and continues to be a disease that disturbs the functioning and quality of life (QOL) of patients.
Aims: To assess the frequency of psychiatric disorders occurring in epileptic patients, determine depression and anxiety levels, and compare the results with healthy controls. The effect of epilepsy on QOL and the effects of social support on epilepsy were also assessed.
Objective: To evaluate the cortical presentation of the hand area according to MRI images of the infarcted area in patients who have predominantly hand weakness.
Background: "Pseudoperipheral palsy" is an old term employed to describe a rare clinical picture consisting of predominant weakness of the hand in association with cerebral infarction. Because the organization of the cortical efferent area of the hand has not been fully defined, this phenomenon merits attention.
