Evaluation of P300 components for emotion-loaded visual event-related potential in elderly subjects, including those with dementia.

Aim: In the present study, the P300 component of the emotion-loaded visual event-related potential in response to photographs of babies crying or smiling was measured to evaluate cognitive function in elderly subjects, including those with dementia.

Methods: The subjects were 48 elderly people who consulted a memory disorder clinic. The visual event-related potential was measured using oddball tasks.

Characteristics of exploratory eye movements in elderly people: possibility of early diagnosis of dementia.

Background: Visual cognitive dysfunction is one of the most important signs indicating the early stage of dementia. Thus, visual testing could be used as an aid to the clinical diagnosis of dementia. In the present study, exploratory eye movement was measured to evaluate visual cognitive function in elderly subjects, including those with dementia.

Effects of emotionally charged sounds in schizophrenia patients using exploratory eye movements: comparison with healthy subjects.

Aims: Emotion-associated sounds have been suggested to exert important effects upon human personal relationships. The present study was aimed to characterize the effects of the sounds of crying or laughing on visual cognitive function in schizophrenia patients.

Methods: We recorded exploratory eye movements in 24 schizophrenia patients (mean age, 27.

A life span study of exploratory eye movements in healthy subjects: gender differences and affective influences.

To evaluate age and gender differences as well as effects of affection, we examined exploratory eye movements. Exploratory eye movements were recorded in healthy subjects (57 women and 57 men) ranging from 9 to 74 years. All subjects were divided into three groups as pre puberty, young, and older adults to study the influences of age and gonadal hormones.
