Speech and Language Disorders in Friedreich Ataxia: Highlights on Phenomenology, Assessment, and Therapy
No successful treatments exist for communication disorders of FRDA patients; however, the tailored speech training or the non-invasive neuromodulation appear as the most reliable therapeutic options to be validate in future trials.
Possibility of Motor Speech Improvement in People With Spinocerebellar Ataxia via Intensive Speech Treatment
People with spinocerebellar ataxia, a hereditary and progressive neurogenic disorder, suffer from ataxic dysarthria due to cerebellar dystrophy. This study was designed to examine if intensive motor
Current concepts in the treatment of hereditary ataxias.
This review describes management for different clinical symptoms, mechanism-based approaches, rehabilitation therapy, disease modifying therapy, future clinical trials and perspectives, genetic counseling and preimplantation genetic diagnosis for Hereditary ataxias.
Dysarthria Profiles in Adults With Hereditary Ataxia.
The findings extend previous research on pure ataxic dysarthria and suggest a possible framework for understanding the speech heterogeneity associated with the ataxias.
Comparing speech characteristics in spinocerebellar ataxias type 3 and type 6 with Friedreich ataxia
Comparisons of dysarthria profiles of patients with SCA3 and SCA6 vs. Friedreich ataxia (FRDA) showed regularity of DDK was specifically impaired inSCA3, whereas impairments of speech parameters, i.e., rate and modulation were stronger affected in SCA 6.
Features of speech and swallowing dysfunction in pre-ataxic spinocerebellar ataxia type 2
Speech and swallowing deficits appear sensitive to disease progression in early-stage SCA2, with syllabic rate a viable marker.
Acoustic Evaluation of Nasality in Cerebellar Syndromes
In conclusion, acoustic analysis showed an increased presence of abnormal nasality fluctuations in all ataxic groups and revealed that nasality fluctuation is associated with distortion of cerebellar functions.
Social and Cultural Elements Associated with Neurocognitive Dysfunctions in Spinocerebellar Ataxia Type 2 Patients
The first analysis about the cultural elements related to the SCA2 disorder in 15 patients previously evaluated with neuroimaging and psychometric instruments and their nuclear relationships distributed in six geographical and cultural regions in Mexico suggests that ethnography can provide social representations to understand the patients’ alterations.
Spinocerebellar ataxia: a critical review of cognitive and socio-cognitive deficits
A comparative summary of the main characteristics of cognitive and social cognition deficit in SCA subtypes has been proposed together with a research agenda for future investigation in this field principally aimed at using measures of cognition and/or social cognition as potential predictors of the extent and progression of disease.


Cerebellar/spinocerebellar syndromes
Clinical and genetic classifications of autosomal dominant and recessive spinocerebellar ataxias are briefly reviewed andinguishing clinical features, diagnostic procedures, and frequency of specific genotypes in Italian patients are presented.

Dysarthria in Friedreich’s Ataxia: A Perceptual Analysis
The notion of subgroups in FRDA dysarthria, representing distinct impairments of the speech mechanism and perhaps reflective of differing evolutions beyond the cerebellum, is supported.
Early symptoms in spinocerebellar ataxia type 1, 2, 3, and 6
Early symptoms that develop before onset of ataxia is mandatory to determine the shift from presymptomatic to affected status in SCA, demonstrating substantial influence of nonrepeat factors on disease onset in all SCA subtypes.
Perceptual and acoustic analysis of speech in individuals with spinocerebellar ataxia (SCA)
Speech samples from 21 subjects with spinocerebellar ataxia, and 21 matched control subjects were analyzed using perceptual and acoustic methodology, revealing significantly reduced speech rate during text reading, reduced alternating and sequential motion rates, and significantly higher vocal instability for subjects with SCA compared to control subjects.
Speech characteristics associated with three genotypes of ataxia.
Differentiating profiles of speech impairments in Friedreich's ataxia: a perceptual and instrumental approach.
The distinct profiles of dysarthria associated with FRDA indicate that approaches that address multiple subsystems are necessary for the accurate characterization and quantification of the motor speech disorder.

In the past decade, the genetic etiologies accounting for most cases of adult-onset dominant cerebellar ataxia have been discovered and can be classified by a simple genetic nosology, essentially a sequential list in which each new SCA is given a number.
