“…The results of the present study corroborate the findings of a study (4) which reported that individuals with PD presented a larger number of stuttering-like dysfluencies and lower speech rate when compared with those of a control group. The difference found in the present study was with regards to typical dysfluencies, which were also more frequent in individuals with PD.…”

“…The presence of dysfluencies in the speech of individuals with PD has been discussed in several studies in the specific scientific literature (1)(2)(3)(4)(5)(6)(7)(8)(9)16,(18)(19)(20)23) . The results of the present study corroborate the findings of a study (4) which reported that individuals with PD presented a larger number of stuttering-like dysfluencies and lower speech rate when compared with those of a control group.…”

“…Regarding speech, hypokinetic dysarthria is present in more than 90% of PD cases. The main symptoms are decreased vocal stress, monotony, hoarse and/or breathy vocal quality, reduction in spoken voice, articulatory inaccuracy, hypernasal resonance, and fluency alterations (1,3,4) . Speech dysfluencies have been reported in several studies conducted with individuals who presented hypokinetic dysarthria owing to PD.…”

“…The most common manifestations cited in these studies were repetition of sounds, syllables, and words; prolongation of sounds; inappropriate and/or excessively long pauses. Another abnormality observed was palilalia, a disorder characterized by compulsive repetition of a statement in a context of increased rate and decreased loudness (1)(2)(3)(4)(5)(6)(7)(8)(9) . In some studies, the number of stuttering disruptions presented by individuals with PD was greater than 3% of stuttered syllables, characterizing a stuttering disorder (4,6,8,10) .…”

The vast majority of cases of stuttering are of idiopathic origin, widely known in the specific scientific literature as persistent developmental stuttering (PDS) (11) , which begins in childhood, during the phase of language acquisition and development, and is characterized as a chronic disorder, even if it presents periods of fluency.…”

RESUMO Objetivo Caracterizar o perfil da fluência da fala de indivíduos com Doença de Parkinson em diferentes tarefas de fala. Método Participaram do estudo 40 indivíduos, de 40 a 80 anos de idade, de ambos os gêneros, divididos em 2 grupos: GP (grupo pesquisa - 20 indivíduos com diagnóstico de Doença de Parkinson); GC (grupo controle - 20 indivíduos sem qualquer alteração de comunicação e/ou neurológica). Para todos os participantes, foram coletadas três amostras de fala envolvendo diferentes tarefas: monólogo, leitura individual e fala automática. Resultados O GP apresentou um número significativamente maior de rupturas, tanto comuns quanto gagas, e maiores porcentagens de descontinuidade de fala e disfluências gagas nas tarefas de monólogo e leitura quando comparado ao GC. Nas tarefas de fala automática, ambos os grupos apresentaram número reduzido de rupturas comuns e gagas, não apresentando diferença significante entre os grupos para esta tarefa. Em relação à velocidade de fala, tanto em palavras quanto em sílabas por minuto, os indivíduos com Doença de Parkinson apresentaram velocidade reduzida em relação ao grupo controle em todas as tarefas de fala. Conclusão O GP apresentou alteração em todos os parâmetros da fluência avaliados no presente estudo quando comparado ao grupo controle, porém esta alteração da fluência não se configura como um quadro de gagueira.

Decline of verbal fluency (VF) performance is one of the most systematically reported neuropsychological adverse effects after subthalamic nucleus deep brain stimulation (STN‐DBS). It has been suggested that this worsening of VF may be related to a microlesion due to the electrode trajectories. We describe the disruption of surrounding white matter tracts following electrode implantation in Parkinson's disease (PD) patients with STN‐DBS and assess whether damage of fiber pathways is associated with VF impairment after surgery. We retrospectively analyzed 48 PD patients undergoing bilateral STN DBS. The lesion mask along the electrode trajectory transformed into the MNI 152 coordinate system, was compared with white matter tract atlas in Tractotron software, which provides a probability and proportion of fibers disconnection. Combining tract‐ and atlas‐based analysis reveals that the trajectory of the electrodes intersected successively with the frontal aslant tract, anterior segment of arcuate tract, the long segment of arcuate tract, the inferior longitudinal fasciculus, the superior longitudinal fasciculus, the anterior thalamic radiation, and the fronto striatal tract. We found no association between the proportion fiber disconnection and the severity of VF impairment 6 months after surgery. Our findings demonstrated that microstructural injury associated with electrode trajectories involved white matter bundles implicated in VF networks.

Background The Controlled Oral Word Association Test (COWAT) evaluates frontal lobe and executive function. Therefore, it can be helpful in differentiating cognitive deficits. However, there are no studies comparing the COWAT performance according to the type and stage of cognitive impairment. Objective To compare performance among persons with Alzheimer dementia (AD), vascular dementia (VaD), and Parkinson disease dementia (PDD) on the COWAT according to stage of cognitive impairment. Design Retrospective chart review. Settings University hospital rehabilitation psychology center. Patients We reviewed the medical records of 246 persons diagnosed with mild cognitive impairment (MCI) or dementia using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐5) and the Korean‐Instrumental Activities of Daily Living (K‐IADL). Patients were divided into a control group, Alzheimer groups (amnestic mild cognitive impairment [aMCI] + AD), Vascular groups (vascular mild cognitive impairment [VaMCI] + VaD), and Parkinson groups (Parkinson disease‐mild cognitive impairment [PD‐MCI] + PDD). Methods Total scores (ie, total number of words produced in 60 seconds on the semantic and phonemic fluency tests of the COWAT) were analyzed. Secondary analysis included calculating percentage scores of words produced during each of the four, 15‐second segments from the total number of words produced in each trial. Results All MCI groups scored significantly lower than the control group on both semantic and phonemic fluency tests. Among the dementia groups, the VaD (mean ± SD, 5.6 ± 5.1) and PDD (5.5 ± 5.5) groups' scores were significantly lower and worse than that of the AD (11.0 ± 8.8) group on the phonemic test (P < .001). The difference in percentage scores was most marked between the PD‐MCI (17.0 ± 2.2) and PDD (1.2 ± 3.1) groups, followed by the VaMCI (13.3 ± 1.9) and VaD (5.6 ± 1.8) groups on the latter phonemic test (P = .007). Conclusions The COWAT is a sensitive test of frontal‐lobe and executive function impairment in persons with MCI. Decreased verbal output in the last 15 seconds of phonemic fluency test is significantly decreased and impaired in persons with VaMCI and PD‐MCI compared to persons with aMCI as they progress to dementia. Level of Evidence III.
