The neural pathways and brain regions involved in eye movements during ocular fixation
and gaze control include the cerebrum, brainstem and cerebellum, and abnormal eye …

Despite extensive research, the functions of the basal ganglia (BG) in movement control
have not been fully understood. Eye movements, particularly saccades, are convenient …

Visual symptoms are common in PD and PD dementia and include difficulty reading, double
vision, illusions, feelings of presence and passage, and complex visual hallucinations …

The cardinal pathophysiology of Parkinson's disease (PD) is considered to be the increase
in the activities of basal ganglia (BG) output nuclei, which excessively inhibits the thalamus …

We reviewed basal ganglia (BG) dysfunction in Parkinson's disease (PD) based on recent
findings on saccade performance. Hypometria in all saccade paradigms and impaired …

The usefulness of eye-tracking tasks as potential biomarkers for motor or cognitive disease
burden in Parkinson's disease (PD) has been subject of debate for many years. Several …

Parkinson's disease, typically thought of as a movement disorder, is increasingly recognized
as causing cognitive impairment and dementia. Eye movement abnormalities are also …

Non-invasive and readily implemented in the clinical setting, eye movement studies have
been conducted extensively not only in healthy human subjects but also in patients with …

Oculomotor abnormalities can be observed in all Parkinsonian syndromes (PS).
Nevertheless, due to the considerable overlap of oculomotor pathology in Parkinsonism …

Parkinson's disease is a neurodegenerative disorder involving the basal ganglia that results
in a host of motor and cognitive deficits. Dopamine-replacement therapy ameliorates some …
