Detecting Cognitive Impairment in Idiopathic Intracranial Hypertension Using Ocular Motor and Neuropsychological Testing

Frontiers in Neurology, 2021
Objective: To determine whether cognitive impairments in patients with Idiopathic Intracranial Hypertension (IIH) are correlated with changes in visual processing, weight, waist circumference, mood or headache, and whether they change over time.Methods ...

Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease. [PDF]

Alzheimers Dement
Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,

Alcohol-Induced Disinhibition of Facial Responses to Pain. [PDF]

Eur J Pain
ABSTRACT Background Alcohol in sub‐toxic dosages has appeared to slightly reduce experimental pain in psychophysical paradigms. However, this effect may also reflect impaired scaling performance in subjective ratings. To address this, we additionally assessed facial responses as a more direct and cognitively unbiased pain measure, while acknowledging ...

Transcranial direct current stimulation (tDCS) of the frontal eye fields during pro- and antisaccade tasks

Frontiers in Psychiatry, 2012
Transcranial direct current stimulation (tDCS) has been successfully applied to cortical areas such as the motor cortex and visual cortex. In the present study, we examined whether tDCS can reach and selectively modulate the excitability of the frontal ...

How age-related noradrenergic dysregulation impacts pupillary response in anti-saccade and prosaccade tasks

Dementia & Neuropsychologia
Aging is associated with multifaceted neurobiological changes that impact cognitive and oculomotor functions, including dysregulation of the locus coeruleus noradrenergic (LC-NA) system.
