To evaluate nonpharmacologic interventions, caregivers (65 women, 38 men) and their dementia-diagnosed spouses (patients) were randomized to one of four treatment programs (cognitive stimulation, dyadic counseling, dual supportive seminar, and early-stage day care) or to a wait-list control group. Assessments occurred initially and at postintervention (3(More)
The problems inherent in using frequency-specific stimuli in the sound field to determine threshold sensitivity are reviewed, including a discussion of some of the specific problems encountered when introducing pure tones, narrow bands of noise, and frequency-modulated (FM) tones. The results of two experiments are reported. In Experiment I, the(More)
Fifteen Alzheimer patients were treated with increasing doses of vinpocetine (30, 45, and 60 mg per day) in an open-label pilot trial during a one-year period. Patients were assessed seven times both on and off drug with: the Buschke Selective Reminding Task, a letter fluency test, a category fluency test, the Boston Naming Test, a cognitive capacity(More)
Performance-intensity (PI) functions for phonetically balanced (PB) word lists were obtained for a group of normal listeners (27 ears), and for two groups of patients with cochlear (89 ears) and retrocochlear disorders (eight ears). Listeners with normal hearing or cochlear disorders exhibited mild to moderate reductions in discrimination score as the(More)
Loudness discomfort level (LDL) and acoustic reflex threshold (ART) measurements were obtained from subjects with normal hearing using several speech stimuli, as well as broad-band and speech-spectrum noise. The purpose of the investigation was to determine the LDL for a variety of representative speech samples, and to determine the relationship between the(More)
Invasive species management is a critical issue worldwide, but mitigation strategies are slow to develop, and invader populations often expand too rapidly for eradication to be feasible. Thus, reduction in numbers of individuals is the most heavily used management strategy for invasive pests. While long-term biocontrol agents may take years or decades to(More)
