Byssinosis not brown. Brown lung can ultimately result in narrowing of the airways, lung scarring and death from infection or respiratory failure. Patient history should reveal exposure to cotton, flax, hemp, or jute dust. Diagnostic tests include a lung function test and a chest x ray or CT scan. Measurable change in lung function before and after working shifts is key to diagnosis. Patients suffering from byssinosis show a significant drop in FEV1 over the course of work shift. Chest radiographs show areas of opacity due to fibrosis of the pulmonary parenchyma. Affected workers should be offered alternative employment. Continued exposure
Signs and symptoms of Graves' disease a high prevalence of neuropsychiatric disorders and mental disorder symptoms in Graves' disease (and thyroid disease in general), which are similar to those in patients with organic brain disease. These manifestations are diverse, affecting the central and peripheral nervous systems.

Anxiety syndromes related to hyperthyroidism are typically complicated by major depression and cognitive decline, such as in memory and attention. Some studies contradict the psychological findings.
