癲癎（上丁堅反廣雅云癲狂也毛詩箋云癲病也聲類云癲風病也或作瘨下音閑集訓云小兒癲病說文云風病也從疒間聲或作𤺛亦通）。

癲癎 (The first character has the fanqie ding + jian. The Guangya says: 'Madness.' The Mao commentary on the Classic of Poetry says: 'Illness.' The Shenglei says: 'A wind affliction.' Also written as 瘨. The second character has the sound xian. The Jixun says: 'Infantile epilepsy.' The Shuowen jiezi says: 'A wind illness; it derives from the "sickness" radical with the phonetic jian.' Also written as 𤺛, which is also acceptable).
