A condition of restlessness or inability to remain still, possibly a rare medical or psychiatric term.
Possibly from Greek 'a-' (without/lacking) + 'tikia' (order/place) + 'mania' (madness), though the etymology is obscure and this may be a very rare or obsolete medical term.
This word is so rare that even medical dictionaries barely acknowledge it—it might be a lost term from 19th-century psychiatry when doctors invented dramatic Greek-Latin hybrids to name conditions they didn't fully understand.
