Entraining with another person's speech rhythm: Evidence from healthy speakers and individuals with Parkinson's disease.

This study examines entrainment of speech timing and rhythm with a model speaker in healthy persons and individuals with Parkinson's. We asked whether participants coordinate their speech initiation and rhythm with the model speaker, and whether the regularity of metrical structure of sentences influences this behaviour. Ten native German speakers with hypokinetic dysarthria following Parkinson's and 10 healthy controls heard a sentence ('prime') and subsequently read aloud another sentence ('target'). Speech material comprised 32 metrically regular and irregular sentences, respectively. Turn-taking delays and alignment of speech rhythm were measured using speech wave analyses. Results showed that healthy participants initiated speech more closely in rhythm with the model speaker than patients. Metrically regular prime sentences induced anticipatory responses relative to metrically irregular primes. Entrainment of speech rhythm was greater in metrically regular targets, especially in individuals with Parkinson's. We conclude that individuals with Parkinson's may exploit metrically regular cues in speech. PMID: 26786186 [PubMed - as supplied by publisher]

Conclusion The patients in the DAT-positive group might have prodromal symptoms that were worsened by neuroleptic drugs. The results of detailed history-taking and neurological findings seem to indicate cases of compromised dopaminergic transmission before the administration of neuroleptic drugs.

Conclusion: More data concerning the safety of antiparkinsonian drugs in PD treatment, as well as the effect of pregnancy on parkinsonian symptoms are needed. According to the current state of the art, L-DOPA therapy should be considered preferable to other drugs during pregnancy.

For a variety of sporadic neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis, it is well-established that ethnicity do affect the disease phenotypes. However, how the ethnicity could contribute to the clinical symptoms and disease progressions in monogenetic disorders, such as spinocerebellar ataxia type 3 (SCA3), remains less studied.
