Mucopolysaccharidosis

Signs and symptoms usually become apparent in early childhood and include speech problems, development delays, challenging behaviors, extreme hyperactivity and poor sleep. [sarepta.com]

Otitis prone children are at risk of developing delayed speech and language development due to conductive hearing loss caused by recurrent AOM with effusion [34]. [smw.ch]
