Aagot Christie Løken (1911 - 2007)

Aagot Christie Løken (1911 – 2007) was a Norwegian physician and neuropathologist.

She was Norway’s first neuropathologist and was central in the establishment of the Scandinavian Neuropathological Association where she later became the first female chairperson.

A skilled and reliable diagnostician, Løken was respected both nationally and internationally. Her rational approach to teaching both students and doctors helped shape future generations in neuropathology, neurology, neurosurgery and neuroradiology. She published 50 scientific papers as well as several textbooks.

She is eponymously remembered for her description of Senior-Løken syndrome in 1961.

Medical Eponyms
Senior-Løken syndrome (1961)

[Also known as: renal-retinal syndrome; juvenile nephronophthisis with Leber amaurosis; renal dysplasia and retinal aplasia]

Autosomal recessive disease with renal failure in childhood or adolescence (nephronophthisis) and Leber’s congenital amaurosis (tapetoretinal degeneration). There are two types; juvenile and adult. In the juvenile type, onset is in early childhood; there is blindness and death from renal failure before the age of 10. The adult type is marked by a later onset and a milder course.

In March 1961, Loken et al published cases of a brother and sister with the main features of nephronophthisis and Leber congenital amaurosis. In November 1961, Senior et al also reported families with an oculorenal syndrome. 

Two siblings, a boy and a girl, with congenital blindness died at 8 and 9 years of age from renal failure. Autopsy was performed in one case. The kidneys showed evidence of dysplasia and of pyelonephritis. Earlier suggestions that renal dysplasia might be the primary cause in cases of chronic pyelonephritis in children are supported. Examination of the eyes indicated a congenital defect, retinal aplasia.
