Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics. Objectives This review aims to characterize speech impairment in APDs, offer practical guidance for clinical evaluation, highlight the role of Speech‐Language pathologists (SLPs) in diagnosis and management, and outline current and emerging management strategies. Methods A narrative review was conducted by the Diagnosis and Treatment Working Group of CurePSP's Centers of Care, integrating literature and clinical experience to summarize evaluation, diagnosis, and treatment of motor speech disorders in APDs. Results Speech changes in APDs are often mixed dysarthrias with hypokinetic, spastic, and/or ataxic components, and may include apraxia of speech; these are frequently more severe and progress quicker than in Parkinson's disease. These features can assist in differential diagnosis and should prompt early referral to SLPs. Despite the high prevalence of speech and voice changes, comprehensive assessment of motor speech disorders is uncommon in neurology clinics. Current evidence regarding the efficacy of interventions is mixed. Digital acoustic analysis and neuromodulation offer promising directions for diagnosis and treatment. Conclusions Early, collaborative management of motor speech impairment elevates care in APDs. Neurologists and SLPs must work together to improve recognition, diagnosis, and care. Future research should focus on objective biomarkers and personalized therapies to support communication, autonomy, and quality of life for individuals living with APDs.

Abstract Background Compared to Parkinson's disease, atypical parkinsonian disorders (APD) are characterized by a more rapidly progressive course, often leading to profound disability. Effective communication between clinicians, patients, and care partners is essential to support patient‐centered care and shared decision‐making. However, most neurologists lack formal training in serious illness conversations (SIC). Objective To develop a practical SIC guide tailored to the needs of individuals with APD. Methods Members of the CurePSP Centers of Care Palliative Care Working Group, in collaboration with a SIC education expert (TC), developed a SIC guide for APD. A literature review was conducted, followed by online consensus‐building rounds. Results Applying core communication principles—such as active listening, pausing, naming and validating emotions, assessing understanding, and reframing—can foster alignment between clinicians, patients, and their care partners. Navigating the balance between maintaining hope and providing realistic, anticipatory guidance remains challenging but best achieved by honest, compassionate dialogue. Four practical guides were developed, addressing common and often challenging scenarios: delivering an APD diagnosis, eliciting patient goals in the context of changing clinical status, addressing safety concerns, and discussing quality of life and end‐of‐life considerations. Conclusions Patients and their care partners living with APD benefit greatly from individualized guidance, and honest, empathic communication is a vital part of patient‐centered care. While existing SIC frameworks offer valuable foundations, further research is needed to optimize their adaptation for APD—identifying best timing, specific frameworks, relevant outcome measures, and education strategies to build team‐wide competency.
