Effect of Levodopa on Speech Dysfluency in Parkinson's Disease.

Objective: To examine the effect of levodopa medication on speech dysfluency in Parkinson's disease. Methods: Fifty-one individuals with Parkinson's disease (IWPD) read aloud during off- and on- medication states. Total speech dysfluencies were calculated from transcriptions of recorded speech samples. Results: Severity of speech dysfluency was not significantly related to the severity of motor symptoms, duration of disease, levodopa equivalent dosage, or age. When the IWPD were divided into two groups based on dysfluency severity, there was a significant group-by-medication state interaction. There was a significant correlation between the medication-related change in speech dysfluency and the off-medication severity of speech dysfluency measure (r = -0.46). Conclusions: The results of this study indicate that levodopa medication can have a significant effect on speech dysfluency. The beneficial levodopa effect appears to be related to the severity of the off-medication speech dysfluency. Results did not provide strong support for the excess dopamine theory of stuttering in IWPD. A dualistic model of the effects of dopamine on speech fluency in PD is proposed.

"My heart is in his hands": The lived spiritual experiences of Congolese refugee women survivors of sexual violence.

The Democratic Republic of Congo (DRC) has experienced widespread violence, including sexual violence. Sexual violence toward women includes rape, genital mutilation, and sexual slavery. Many Congolese have sought to escape such conditions as refugees in the USA. In the present study, we examined lived spiritual experiences of nine Congolese refugee women survivors of sexual violence. Overall, this study provides new insights into participants' experiences of spirituality in the aftermath of sexual trauma and in living as a refugees. Consensual qualitative research (CQR) methods were used to analyze participants' responses to a semistructured interview protocol. Participants endorsed faith that God was in control, reliance on prayer, gratitude toward God, and difficulty practicing their faith in the USA relative to Africa. Results indicated that religion/spirituality is an integral part of the women's lives and that it appears to facilitate coping. Clinical and community mental health implications are discussed.
