Sintesi	The GRBAS Scale (Grade, Roughness, Breathiness, Asthenia, Strain) is a clinician-rated perceptual assessment tool for classifying voice quality across five distinct vocal dimensions. Developed by Hirano in 1981, GRBAS provides a standardized language for voice clinicians and physicians to describe dysphonia characteristics (e.g., rough voice, breathy voice, weak voice) using ordinal subscales. GRBAS is foundational in voice pathology education and remains widely used in clinical and research settings despite modern objective measures like acoustic analysis and laryngeal imaging.	The Boston Diagnostic Aphasia Examination Severity Rating Scale (BDAE-SRS) is the gold-standard clinician-administered assessment of aphasia severity and type in adults following stroke or acquired brain injury. Developed by Goodglass, Kaplan, and colleagues (2001, third edition), BDAE provides comprehensive evaluation of language across 18 domains (auditory comprehension, oral expression, naming, repetition, reading, writing) and yields both an overall severity rating (0–5 scale) and a detailed profile classifying aphasia syndrome (Broca's, Wernicke's, conduction, global, etc.). BDAE is foundational to aphasia diagnosis, prognosis, and treatment planning.
