cranial anomaly

an abnormal head due to a congenital defect. The head may be abnormally large (as in hydrocephalus), abnormally small (as in microcephaly), or square shaped (as in some cases of osteopetrosis), or it may have sutures that fail to close. The defect is often related to a chromosome abnormality. Chromosomes 17 and 18 are often involved through trisomy or other aberrations.

Clérambault’s syndrome

a form of erotic paranoia in which a person has delusions that someone else, who is typically older and of higher social status, is in love with him or her. The person continues to hold this belief despite having little contact with the other person and no reciprocation of feelings. The condition is more common in females than in males. Also called de Clérambault’s syndrome. [first described in 1922 by Gaëtan Gatian de Clérambault (1872–1934), French physician]
