Prosody matters: Preserved prominence marking strategies in people with Parkinson's disease independent of motor status.

While many studies focus on segmental variation in Parkinsonian speech, little is known about prosodic modulations reflecting the ability to adapt to communicative demands in people with Parkinson's disease (PwPD). This type of prosodic modulation is important for social interaction, and it involves modifications in speech melody (intonational level) and articulation of consonants and vowels (segmental level). The present study investigates phonetic cues of prosodic modulations with respect to different focus structures in mild dysarthric PwPD as a function of levodopa.

One side effect: two networks? Lateral and posteromedial stimulation spreads induce dysarthria in subthalamic deep brain stimulation for Parkinson's disease.

Background: Stimulation-induced dysarthria (SID) is a troublesome and potentially therapy-limiting side effect of deep brain stimulation of the subthalamic nucleus (STN-DBS) in patients with Parkinson's disease (PD). To date, the origin of SID, and especially whether there is an involvement of cerebellar pathways as well as the pyramidal tract, remains a matter of debate. Therefore, this study aims to shed light on structural networks associated with SID and to derive a data-driven model to predict SID in patients with PD and STN-DBS.

An automatic measure for speech intelligibility in dysarthrias-validation across multiple languages and neurological disorders.

Introduction: Dysarthria, a motor speech disorder caused by muscle weakness or paralysis, severely impacts speech intelligibility and quality of life. The condition is prevalent in motor speech disorders such as Parkinson's disease (PD), atypical parkinsonism such as progressive supranuclear palsy (PSP), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Improving intelligibility is not only an outcome that matters to patients but can also play a critical role as an endpoint in clinical research and drug development.

Compensatory articulatory mechanisms preserve intelligibility in prodromal Parkinson's disease.

Introduction: Dysarthria is highly prevalent in patients with Parkinson's disease (PD) and speech changes have already been detected in patients with prodromal PD on the acoustic level. However, the present study directly tracks underlying articulatory movements with electromagnetic articulography to investigate early speech alterations on the kinematic level in isolated REM sleep behavior disorder (iRBD) and compares them to PD and control speakers.

Methods: Kinematic data of 23 control speakers, 22 speakers with iRBD, and 23 speakers with PD were collected.

Task-based profiles of language impairment and their relationship to cognitive dysfunction in Parkinson's disease.

Objective: Parkinson's Disease (PD) is associated with both motor and non-motor problems, such as cognitive impairment. Particular focus in this area has been on the relationship between language impairment and decline in other cognitive functions, with the literature currently inconclusive on how the nature and degree of language impairment relate to cognition or other measures of disease severity. In addition, little information is available on how language problems identified in experimental task set-ups relate to competency in self-generated language paradigms such as picture description, monologues or conversations.

Levodopa-Based Changes on Vocalic Speech Movements during Prosodic Prominence Marking.

The present study investigates speech changes in Parkinson's disease on the acoustic and articulatory level with respect to prosodic prominence marking. To display movements of the underlying articulators, speech data from 16 patients with Parkinson's disease were recorded using electromagnetic articulography. Speech tasks focused on strategies of prominence marking.

Thalamic Deep Brain Stimulation in Essential Tremor Plus Is as Effective as in Essential Tremor.

The new essential tremor (ET) classification defined ET-plus (ET-p) as an ET subgroup with additional neurological signs besides action tremor. While deep brain stimulation (DBS) is effective in ET, there are no studies specifically addressing DBS effects in ET-p. 44 patients with medication-refractory ET and thalamic/subthalamic DBS implanted at our center were postoperatively classified into ET and ET-p according to preoperative documentation.

Network Fingerprint of Stimulation-Induced Speech Impairment in Essential Tremor.

Objective: This study was undertaken to gain insights into structural networks associated with stimulation-induced dysarthria (SID) and to predict stimulation-induced worsening of intelligibility in essential tremor patients with bilateral thalamic deep brain stimulation (DBS).

Methods: Monopolar reviews were conducted in 14 essential tremor patients. Testing included determination of SID thresholds, intelligibility ratings, and a fast syllable repetition task.

The effects of thalamic and posterior subthalamic deep brain stimulation on speech in patients with essential tremor - A prospective, randomized, doubleblind crossover study.

Objective: To prospectively evaluate the effect of PSA- and VIM DBS on speech in ET patients.

Methods: Leads were implanted bilaterally with contacts placed in both VIM and PSA. Thirteen patients were analyzed pre- and postoperatively.

Prominence marking in parkinsonian speech and its correlation with motor performance and cognitive abilities.

Objectives: Research suggests that people with Parkinson's disease (PwPD) do not only suffer from motor but also non-motor impairment. This interdisciplinary study investigated how prominence marking is influenced by problems on the motoric and cognitive level.

Materials And Methods: We collected speech production data from 38 native German speakers: 19 PwPD (under medication) with a mild to moderate motor impairment, 13 males and 6 females (mean 66.

Evaluation of a German version of the Bain and Findley Tremor ADL scale.

The Movement Disorder Society recommends the Bain and Findley Tremor ADL Scale to assess ADL in patients with ET. In 45 medically and 14 surgically (DBS) treated ET patients, a German version of the scale correlated well with tremor severity and quality of life and was sensitive to postoperative change.
