Sintesi	The MIDAS is a brief, five-item self-report questionnaire that quantifies migraine-related disability by measuring days lost from work, school, household activities, and family/social activities over a 3-month period. Introduced by Stewart and colleagues in 1999, it is the most widely used measure of migraine burden in clinical practice and research. MIDAS directly translates migraine frequency and severity into functional impact (lost productivity, lost days), enabling healthcare providers and patients to understand the true disability burden of migraines.	The SS-QoL is a disease-specific quality-of-life instrument designed to capture the multidimensional impact of stroke on survivors' functional and emotional well-being. Developed by Williams and colleagues in 1999, this 49-item scale addresses stroke-specific concerns including language, cognition, mobility, and emotional functioning. It is a gold-standard instrument for stroke outcome research and routine clinical monitoring of post-stroke recovery.
