Summary: This study investigated the effects of consecutive physiotherapy and cognitive rehabilitation on cognitive, motor, and psychological aspects in Parkinson's disease patients. Results showed that patients who received consecutive training performed better in functional mobility and memory tasks, supporting the hypothesis that consecutive physiotherapy plus cognitive rehabilitation may be more beneficial than physiotherapy alone.

Summary: Visual hallucinations are common symptoms of Parkinson's Disease, and are associated with impairments in perceptual processing and modulation. This study found that perceptual performance in PD patients is related to the presence of hallucinations, as well as abnormal top-down perceptual modulation.

Summary: Individuals with schizophrenia who exhibit deficits in visual contrast processing also show impairment in neurocognition and functional outcomes. This study found that contrast sensitivity, particularly to low spatial frequencies, is associated with cognitive function as a mediator for independent living capacity. Perceptual organization and memory-related domains were identified as key factors in mediating this relationship.

Summary: Depressive symptoms in Parkinson's disease (PD) are multifactorial, including both dopaminergic deficit and chronic illness-related reactions. The prevalence and severity of depressive symptoms are similar between PD patients and disease controls (DC), though PD patients use antidepressants, especially Mirtazapine, more frequently. However, a significant proportion of patients in both groups with clinically significant depressive symptoms were not receiving medication. The diagnosis and treatment of depressive symptoms in both PD and DC should be improved.

Summary: Falls are common and harmful for people with Parkinson's disease, with medication having limited effectiveness in reducing them. Exercise therapy can help reduce falls objectively, but improving both self-perceived and objective fall risk is important for enhancing overall quality of life in PD patients.

Summary: This study aimed to improve the restoration effect of retinal prostheses on vision for blind individuals using object isolation algorithm and image processing techniques. The results indicated an enhancement in perceived shape, contrast, and dynamic range of objects in the phosphene image.

Summary: This meta-analysis of 52 RCTs suggests that low vision rehabilitation has significant effects on improving vision-related QoL and visual functioning in visually impaired adults. However, compared to active comparators, no significant difference was found in health-related QoL and adaptation to vision loss.

Summary: The study revealed that contrast sensitivity is significantly reduced in CSCR and strongly correlates with subjective visual impairment. Different structural biomarkers are associated with contrast thresholds reductions at different spatial frequencies.

Summary: This study demonstrated a strong association between lower-level visual dysfunction and cognitive performance in Parkinson's disease, especially when cognitive tests are based on visual input. High and low-contrast visual acuity were significantly correlated with visual cognition in PD patients.

Summary: This meta-analysis investigated visual and cognitive impairments in Parkinson's Disease Psychosis (PDP) patients. The results showed that PD patients with visual hallucinations (PDVH) performed worse than those without hallucinations (PDnoVH) in various measures of cognition and visual processing, with executive functions, attention, episodic memory, and visual processing showing the greatest differences. This study highlights the need for a broader range of cognitive and processing domains to be considered in models of PDVH.

Summary: Visual dysfunction in Parkinson's disease predicts dementia and poor outcomes, while retinal thickness has less predictive power. This suggests that cortical structures play a role in the progression of Parkinson's dementia, and visual tests may be useful for stratification in clinical trials.

Summary: Human infants are sensitive to social information in their visual world. A study measured 9-month-old infants' sensitivities to face-like configurations and found that infants' performance dropped beyond a certain eccentricity, indicating lower sensitivity to face-like stimuli far from the center of their visual field.

Summary: The study found that high-anticholinergic load is significantly associated with lower stage of recovery, poor mental well-being, poor self-rated medication adherence, and poorer delayed-episodic memory. Additionally, high-anticholinergic score is also related to faster completion time on tests exploring executive performance.

Summary: The development of visual prosthesis devices faces challenges in understanding factors such as phosphenes and how electrical patterns influence phosphenes generation. Research on synchronous and asynchronous electrical stimulation across multiple electrodes is crucial for creating a clinically successful prosthesis.
