Notes: Summary The study reported here was undertaken to establish the degree to which a person in a preclinical state of hyperthyroidism, with (by definition) euthyroid T3 and T4 levels but suppressed TRH on testing, already exhibits psychological changes and clinical symptoms. Two groups of 20 patients each, with clear clinical and preclinical hyperthyroidism (as defined by laboratory parameters), were studied, as well as a group of 20 controls. The subjects' psychological state of mind was investigated using self-rating scales, including the state-trait-anxiety inventory (STAI), „Befindlich-keits“-Skala (Bf-S'), depression scale (D-S'), and a list of adjectives (EWL-K) with 14 different aspects of affective moods. Cognitive achievements were evaluated using the d2 test. Subjects were examined for somatic symptoms in accordance with Crooks' index of hyperthyroidism. The results clearly showed that typical psychological and somatic changes are already present in preclinical hyperthyroidism, these changes being partly identical with those of definite hyperthyroidism. In both patient groups, a significant increase in anxiety, a sense of not feeling well, and emotional irritability were found, as well as a tendency towards depressiveness, and an increased lack of vitality and activity. Attentiveness and concentration in both patient groups were lower than in the control group. Both patient groups showed the same prevalence of symptoms, such as palpipations, preference of cold over heat, excessive sweating, nervousness, fine digital tremor, and increased heart rate. With regard to the results, the diagnosis “preclinical hyperthyroidism” thus gains importance. Further prospective studies are required to answer the question whether antithyroidal treatment will influence the described psychological and somatic state of patients with preclinical hyperthyroidism.

Notes: Summary Although the psychological disturbances accompanying Graves' disease are well known, the time required for normalisation of these disturbances during antithyroid drug treatment is not known. Therefore sequential psychological testing during the course of Graves' disease was done. There are also contradictory results concerning the possible correlation of neurophysiological and psychological test results during the course of Graves' disease with thyroid hormone values. Finally, psychological disturbances have been proposed as possible etiologic factors in Graves' disease. In our study, a significant decrease in anxiety and irritability could be observed at the time euthyroidism was achieved. Self-evaluations of depressivity, activity, exhaustion, well-being, extraversion, introversion, and the ability to concentrate changed 1 or 2 months after euthyroidism was induced. Similar test results could be observed after induction of euthyroidism by antithyroid drugs and subtotal thyroid resection. Therefore the mode of therapy does not seem to influence the course of normalisation of psychological parameters. In contrast to other investigations there was hardly any correlation between thyroid hormone values and psychological test results or the ability to concentrate. Nontheless, patients with Graves' disease showing high scores for depression and anxiety exhibit abnormal peripheral helper/suppressor T-lymphocyte relations. Furthermore, patients suffering from Graves' disease tend to be more anxious than controls. It remains to be determined whether an increased susceptibility to psychological disturbances has led to these alterations of lymphocyte subsets in Graves' disease patients with severe depression and anxiety.

Notes: Summary The characteristic psychic and somatic features found in patients with overt hyper- or hypothyroidism are usually attributed to elevated or diminished levels, respectively, of thyroid hormones. This concept does not sufficiently explain our previous investigations in which the same symptoms, albeit attenuated, were also seen in patients suffering from so-called latent disturbances of thyroid function. This state of disorder, however, exhibits normal concentrations of peripheral thyroid hormones. Only the response of thyroid-stimulating hormone (TSH) to thyrotropin-releasing hormone (TRH) stimulation is in accordance with the behaviour of the overt thyroid dysfunction and enables its differentiation from the euthyroid state. In this context, we investigated the question as to whether pathologic signs in thyroid disorders are correlated to alterations of peripheral thyroid hormones or to changes in the hypothalamus pituitary axis. Therefore, we investigated two groups of ten patients each who suffered from latent hyper- or hypothyroidism, respectively, and ten euthyroid controls. All were matched from sex and age. Endocrine function was estimated by TRH testing, TT3, TT4 and thyroxine binding globuline (TBG). Psychologic testing was performed by questionnaires concerning subjective somatic symptoms, emotional disturbances, psychomotoric performance, cognitive impairment and personality. Patients with latent hyperthyroidism were more subject to somatic symptoms and affective complaints than were those who had latent hypothyroidism. As compared with controls, there were significant differences in exhaustion and pain in the limbs and heart. In terms of affective complaints, patients were more depressive, anxious, touchy and irritable; their personalities showed a higher degree of emotional lability, excitement and irritability. Many symptoms described in overt thyroid dysfunction could be found in latent metabolic disturbances. Therefore, we conclude that the alterations of health in thyroid disorders are more likely to be caused by hypothalamic pituitary impairment than by changes in peripheral hormone levels. The stronger symptoms occurring in overt thyroid dysfunction as compared with latent metabolic disturbances may reflect the degree of hypothalamic pituitary dysfunction.
