Circadian hormonal rhythms in two new cases of fatal familial insomnia.
We used a chronobiological inferential statistical method to investigate circadian rhythms of hypophyseal hormones, cortisol, melatonin and catecholamines in two females of the same family affected by fatal familial insomnia. Case 1 (confirmed at autopsy) presented an absent or progressive loss of circadian rhythms of all hormones. In case 2 there was a loss of GH circadian rhythm and a less significant rhythm for melatonin, catecholamines and gonadotropins. These results confirm the role of the thalamus in regulating hormonal circadian rhythm.
