Visual perceptual dysfunction in patients with schizophrenic and affective disorders versus control subjects.

Visual perception was evaluated with standard tests for 26 hospitalized patients with schizophrenia, 23 hospitalized patients with affective disorders, and 60 control subjects. Both patient groups differed significantly from the control group on low amplitude of accommodation, esophoria or exophoria, vergence duction suppression, and convergence and divergence recovery ductions. Only the affective group showed significantly reduced fusion at near distance, and only the schizophrenic group differed significantly from control subjects on disorganized left apex formation. These findings appear to confirm the presence of visual perceptual disorders that can cause disability in psychiatric patients, with important research and rehabilitation implications.

Serum concentrations of circulating thyroid hormones in a group of depressed men.

Levels of circulating total thyroxine (TT4), free thyroxine (FT4), total triiodothyronine TT3 and thyrotropin (TSH) were determined in 27 men with unipolar major depressive disorder ages 24-50, mean +/- SEM 36.9 +/- 2.9 years, and 38 healthy controls (HC) ages 20-50, mean +/- SEM 34.2 +/- 3.1 years. No significant differences were observed between HC and depressed men with regard to TT4 and FT4. Mean TT3 levels were lower, and mean TSH levels higher in depressed patients than in HC, p less than 0.05 for both, compatible with possible subclinical primary hypothyroidism in depressed patients. Consistent with this, an inverse correlation between basal TSH values and TT3 (r = -0.38, p less than 0.05) was noted in depressed but not in HC subjects.
