Parkinson's disease (PD) reportedly show disturbed visual exploration. However, whether this disturbance is due to dysfunctional visual information processing remains unclear. To clarify the effects of PD on visual information processing when exploring for targets and to compare disease effects with aging effects, we used an infrared eye-movement assessment system.

- The study investigates the link between executive dysfunction (ED) in Parkinson's disease (PD) and brain connectivity assessed through EEG coherence.
- The research involved 68 non-demented PD patients who were evaluated with a specific test for executive function and analyzed brain activity in two electrode pairs during different frequency ranges.
- Results showed that lower EEG coherence on the left side was associated with worse executive function, indicating that decreased connectivity may contribute to executive dysfunction in PD patients.
Article Synopsis
- Postural deformities and executive dysfunction (ED) are common issues in Parkinson's disease (PD), but their relationship isn't well understood.
- A study with 65 PD patients assessed the severity of postural deformities and executive function using specific rating scales and tests.
- Results showed a significant correlation between the severity of postural deformities and ED, indicating that more severe deformities are linked to poorer executive function, suggesting a connection to frontal dysfunction in PD patients.
Glossopharyngeal and/or vagus nerve involvement is infrequent in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We herein report the case of a 69-year-old Japanese woman who presented with muscle weakness and numbness of the extremities with dysphagia. The serum anti-ganglioside GM1 immunoglobulin IgM antibody levels were elevated, and treatment with intravenous immunoglobulin (IVIg) resulted in a dramatic improvement; the weakness, numbness and dysphagia all resolved.

- A 37-year-old woman developed gait issues due to sensory loss in her left leg three years after being diagnosed with clinically isolated syndrome.
- MRI scans revealed an incomplete ring-enhanced lesion in the right parietal lobe, accompanied by swelling, while MET-PET showed no significant uptake in the lesion.
- She was diagnosed with tumefactive multiple sclerosis and treated with corticosteroids, leading to improvements; the imaging results help distinguish between demyelinating lesions and brain tumors.
A previously healthy 63-year-old man presented with a 2-weeks history of diplopia without headache. Neurological examination revealed total external ophthalmoplegia of the left eye and limitation of abduction of the right eye. Initial cranial MRI showed thickening and enhancement of the dura mater only on the anterior cranial fossa but unremarkable on the cavernous sinus.

Introduction: Freezing of gait (FOG) is a common symptom of Parkinson's disease (PD). Although the pathophysiological mechanism of FOG is unknown, previous studies have suggested that frontal dysfunction is associated with FOG. The Behavioral Assessment of the Dysexecutive Syndrome (BADS) battery, which is wide-ranging neurological battery composed of six subtests, evaluates frontal function and is more sensitive to executive dysfunction (ED) than other tools in PD patients.
