It has been reported to occur from exposure to inhaled toxins and gases including sulfur mustard gas, nitrogen oxides, diacetyl (used in many food and beverage flavorings), 2,3-pentanedione, fly ash and fiberglass. COPD
Chronic obstructive pulmonary disease is a respiratory disease that can encompass chronic bronchitis and/or emphysema. 15% of the cases of COPD in the United States can be attributed to occupational exposure, including exposure to silica and coal dust. People who work in mining, construction, manufacturing (specifically textiles, rubber, plastic, and leather), building, and utilities are at higher risk for COPD than the average US worker. Hypersensitivity pneumonitis
Hypersensitivity pneumonitis (HP; also called allergic alveolitis, bagpipe lung, or extrinsic allergic alveolitis, EAA) is an inflammation of the alveoli within the lung caused by hypersensitivity to inhaled organic dusts. Lung cancer
Numerous categories of ionizing radiation, chemicals and mixtures, occupational exposures, metals, dust and fibers have been linked to occurrence of lung cancer. Mesothelioma
Mesothelioma is a cancer of the mesothelium, part of which is the pleura, the lining of the lungs. Mesothelioma is caused by exposure to asbestos. Pneumoconiosis
Pneumoconiosis are occupational lung diseases that are caused due to accumulation of dust in the lungs and bodys reaction to its presence. Most common pneumoconiosis are silicosis, coal workers’ pneumoconiosis (CWP), and asbestosis. Other examples include minerals (such kaolin, talc, mica), beryllium lung disease, hard metal disease and silicon carbide pneumoconiosis. Smoke Inhalation
Inhaling smoke and other byproducts of combustion can cause pulmonary injury.
Acephalgic migraine (also called migraine aura without headache, amigrainous migraine, isolated visual migraine, and optical migraine) is a neurological syndrome. It is a relatively uncommon variant of migraine in which the patient may experience some migraine symptoms such as  aura, nausea, photophobia, and hemiparesis, but does not experience headache. It is generally classified as an event fulfilling the conditions of migraine with aura with no (or minimal) headache. It is sometimes distinguished from visual-only migraine aura without headache, also called ocular migraine. Symptoms and misdiagnosis
Acephalgic migraines can occur in individuals of any age. Some individuals, more commonly male, only experience acephalgic migraine, but frequently patients also experience migraine with headache. Generally, the condition is more than twice as likely to occur in females than males. Pediatric acephalgic migraines are listed along with other childhood periodic syndromes by W.A. Al-Twaijri and M.I. Shevell as "migraine equivalents" (although not listed as such in the International Classification of Headache Disorders), which can be good predictors of the future development of typical migraines. Individuals who experience acephalgic migraines in childhood are highly likely to develop typical migraines as they grow older. Among women, incidents of acephalgic migraine increase during perimenopause.Scintillating scotoma is the most common symptom which usually happens concurrently with Expanding Fortification Spectra. Also frequently reported is monocular blindness. Acephalgic migraines typically do not persist more than a few hours and may last for as little as 15 seconds.
