This study concerns the frequency and degree of root resorption in traumatized incisors that have been treated orthodontically. The subjects were twenty-seven patients (fifteen boys and twelve girls) with fifty-five traumatized incisors; fifty-five consecutive patients without traumatized teeth served as controls. All the control patients were treated with(More)
Primary presenile dementia slows the major positive component of the visual evoked potential to flash stimulation but does not affect the visual evoked potential to patterned stimulation. The progressive effect of Alzheimer's disease was followed in a 58 year old woman over three and a half years from the development of the earliest symptoms to complete(More)
The depressive Attributional Style Questionnaire (Peterson et al., 1982) and the Hassles and Uplifts Questionnaire (Kanner et al., 1981) were administered to melancholic and non-melancholic depressed patients (matched for severity according to a doctors/nurses rating scale), and to non-depressed volunteers. Compared to the other two groups, melancholic(More)
The use of the flash and pattern reversal visual evoked potential (VEP) in the diagnosis of primary presenile dementia was investigated. The results from 20 patients with primary presenile dementia were compared with those from a control group of normals of equivalent age and from a control group of 20 patients with cortical atrophy but no dementia.(More)
Ninety-one patients with forgetfulness, confusion and depression were referred for visual evoked potential and electroencephalographic investigation. The patients were subdivided, on clinical symptoms alone, into a group of 41 with evidence of dementia and a patient control group of 50 with affective disorders. A second control group of 30 normal volunteers(More)
Flash, pattern reversal and pattern onset-offset VEPs were recorded in 17 patients with a clinical diagnosis of presenile dementia. The results were compared with those from two control groups--17 normal volunteers of equivalent ages and 17 patients from the same psychiatric hospital with affective disorders but no clinical evidence of dementia. The flash(More)
