Catecholamine Depletion in Thyrotoxicosis

Catecholamine Depletion in Thyrotoxicosis. Effect of Guanethidine on Cardiovascular Dynamics.

Effects of tryptophan depletion vs catecholamine depletion in patients with seasonal affective disorder in remission with light therapy.

BACKGROUND Although hypotheses about the therapeutic mechanism of action of light therapy have focused on serotonergic mechanisms, the potential role, if any, of catecholaminergic pathways has not been fully explored. METHODS Sixteen patients with seasonal affective disorder who had responded to a standard regimen of daily 10000-lux light therapy were enrolled in a double-blind, placebo-contr...

" Scire est nescire, nisi id me Scire alius sciret SPRING, 194:1. It would not be possible to deal at all fully with the scientific aspects of this subject in an article of reasonable length, and still less would it be possible to give a resume of the enormous literature that has grown up concerning it. My purpose is much simpler ; it is to present a record of personal experience and to offer s...

Thyrotoxicosis.

Thyrotoxicosis is a common disorder, especially in women. The most frequent cause is Graves' disease (autoimmune hyperthyroidism). Other important causes include toxic nodular hyperthyroidism, due to the presence of one or more autonomously functioning thyroid nodules, and thyroiditis caused by inflammation, which results in release of stored hormones. Antithyroid drugs are the usual initial tr...

Reward processing after catecholamine depletion in unmedicated, remitted subjects with major depressive disorder.

BACKGROUND We investigated whether performance on a reward processing task differs between fully remitted patients with major depressive disorder (MDD) and healthy control subjects after catecholamine depletion. METHODS Seventeen unmedicated subjects with remitted MDD (RMDD) and 13 healthy control subjects underwent catecholamine depletion with oral alpha-methyl-para-tyrosine (AMPT) in a rand...
