Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is inherited microangiopathy characterized by recurrent subcortical infarcts. A majority of those with CADASIL report coexistent migraine with aura. The authors aim to quantitatively describe migraine-related disability within a CADASIL cohort.
A cross-sectional analysis was performed in a cohort of CADASIL. The Migraine Disability Assessment (MIDAS) quantified migraine-related disability. Further metrics obtained include first and last migraine, aura semiology, and therapeutic measures.
Twenty-four individuals were included [63% (15/24) female individuals; mean age, 56 y; range, 34 to 81 y]. Fifty-four percent (13/24) reported migraine, whereas 46% (11/24) reporting varying degrees of migraine-related disability. MIDAS Questionnaire scores appeared bimodal: 58% (14/24) scored 0 to 5, 7% (1/24) scored 6 to 10, 7% (1/24) scored 11 to 20 and 33% (8/24) scored over 20. Severe disability was associated with the multiplicity of aura semiologies and poor response to pharmacologic prophylaxis.
A bimodal distribution of migraine-related disability was observed. A third of individuals had a severe disability and appeared medically refractory to medical migraine prophylactic measures. This study may serve as a reference point for future trials quantitatively gauging response of novel migraine treatment strategies within this unique population.
