Developmental stuttering and Parkinson's disease: the effects of levodopa treatment.
نویسندگان
چکیده
The effects of dopamine on developmental stuttering was studied in a 44 year old man with developmental stuttering and Parkinson's disease during three levodopa "on" periods and three "off" periods. When compared with the "off" periods, during the "on"' periods he demonstrated an increase of speech dysfluencies. These findings lend support to the dopamine hypothesis of developmental stuttering.

متن کاملTHERMODYNAMIC STUDY OF LEVODOPA DRUG ADSORPTION ON ZIGZAG BORON NITRIDE NANOTUBES BY DENSITY FUNCTIONAL THEORY (DFT) METHOD
Background & Aims: The overall goal of utilizing nanotubes in drug delivery is to treat a disease effectively with minimum side effects and control the drug release rate. With common methods of taking the medication, such as orally and intravenously, the drug is distributed throughout the body, and the whole body is affected by the drug, and adverse side effects occur. With the development of n...

متن کاملParkinson's Disease: Low-Dose Haloperidol Increases Dopamine Receptor Sensitivity and Clinical Response
Background. It is known that ultra-low doses of haloperidol can cause dopamine supersensitivity of dopamine D2 receptors and related behaviour in animals. Objective. The objective was to determine whether a daily ultra-low dose of 40 micrograms of haloperidol could enhance the clinical action of levodopa in Parkinson's disease patients. Method. While continuing their daily treatment with levodo...
