Purpose of reviewThe recent literature on spasmodic dysphonia is reviewed with regard to pathogenesis, differential diagnosis, treatment options, audits, and current methods of management. Recent findingsAdvances in technology have enabled clinicians to better understand the connection between brain and laryngeal function and dysfunction. Refinements in imaging and genetic investigation techniques have led to advances in the understanding of the underlying mechanism of this neurolaryngeal…

TLDR
The citation of Traube’s “hysterical” patient links to mid 20th–century views of the functional nature of SD and the utility of psychiatric treatment and the description presented by Mackenzie is consistent with current views of SD as a movement disorder.
Consensus-Based Attributes for Identifying Patients With Spasmodic Dysphonia and Other Voice Disorders
TLDR
Specialists without guidelines had poor agreement when classifying patients for research, leading to a Delphi-based development of the Spasmodic Dysphonia Attributes Inventory for classifying Patients with ADSD, ABSD, VT, and MTD for research.
Long-Term Follow-Up of Patients with Spasmodic Dysphonia and Improved Voice despite Discontinuation of Treatment
TLDR
It seems plausible that the symptoms of spasmodic dysphonia may decrease over time, and early intervention and male gender seem to be important factors for long-term reduction of the voice symptoms of AdSD.
Quality of Life and Voice Changes After a Single Injection in Patients With ADSD Over Time.
Deep Learning Application for Vocal Fold Disease Prediction Through Voice Recognition: Preliminary Development Study
TLDR
This approach involving artificial intelligence could be clinically useful for screening general vocal fold disease using the voice during telemedicine in areas with primary care units lacking laryngoscopic abilities.

Spastic dysphonia, Meige disease, and torsion dystonia
To the Editor: Jacome and Yanez comment on a n association of spastic dysphonia and Meige disease (Brueghel syndrome),’ and state that they know of no association of these two disorders. In fact,
The clinical spectrum of laryngeal dystonia includes dystonic cough: Observations of a large series
TLDR
Patients with adductor SD, stridor, extra‐laryngeal dystonia and male patients had relatively better treatment outcomes, and BTX injections are very effective across all subgroups.
Alcohol responsiveness in laryngeal dystonia: a survey study
TLDR
The data suggest that isolated dystonic symptoms, such as in LD, are responsive to alcohol intake and this responsiveness is not attributed to the presence of VT, which is known to have significant benefits from alcohol ingestion.
Dystonia: an update on phenomenology, classification, pathogenesis and treatment.
TLDR
Phenotypic classification continues to be important to recognize particular forms of dystonia and this includes syndromic associations and there will be further new discoveries with the advances in genetic technologies such as exome and whole-genome sequencing.
The Mayo Clinic Arizona Spasmodic Dysphonia Experience
TLDR
The Mayo Clinic Arizona SD experience compares to prior reports and reveals a female preponderance, onset in middle age, infrequent hereditary pattern, high co-occurrence of VT, and low co-Occurrence of other dystonias.
Spasmodic dysphonia follow-up with videolaryngoscopy and voice spectrography during treatment with botulinum toxin
TLDR
The efficacy of the treatment of SD with BTX with objective measurements is supported and suggests that the efficacy of recurring treatments is stable over time.
