Bromism is caused by a neurotoxic effect on the brain which results in somnolence, psychosis, seizures, and delirium. [2] Bromism has also been caused by excessive consumption of soda that contains brominated vegetable oil , leading to headache , fatigue , ataxia , memory loss , and potentially inability to walk as observed in one case.
The formation of bubbles in the skin or joints results in milder symptoms, while large numbers of bubbles in the venous blood can cause lung damage. [11] The most severe types of DCS interrupt — and ultimately damage — spinal cord function, leading to paralysis , sensory dysfunction, or death.
CNH is the human body's response to reduced carbon dioxide levels in the blood. This reduction in carbon dioxide is caused by contraction of cranial arteries from damage caused by lesions in the brain stem. However, the mechanism by which CNH arises as a result from these lesions is still very poorly understood.
[6] [8] The mechanism behind these symptoms beyond solvent molecules crossing the blood–brain barrier is currently unknown. Neurological signs include impaired vibratory sensation at extremities and an inability to maintain steady motion , a possible effect from psychomotor damage in the brain.
When high pressure is pushing on the walls of narrowed blood vessels, fluid leaves the inside of blood vessels and moves to the space just outside. This impairs necessary blood flow and cuts off circulating oxygen, which can lead to tissue death and permanent damage to the brain, heart, arteries, and kidneys.
Lung symptoms in a patient who is taking a medicinal drug that can cause pulmonary toxicity should not automatically lead to a diagnosis of "pulmonary toxicity due to the medicinal drug", because some patients can have another (i.e., simultaneous) lung disease, e.g. an infection of the lungs not related to the medicinal drugs the patient is ...
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
[10] [13] Too much blood (a clinical condition of a normal homeostatic response of hyperemia) [1] can raise intracranial pressure (ICP), which can compress and damage delicate brain tissue. Too little blood flow ( ischemia ) results if blood flow to the brain is below 18 to 20 ml per 100 g per minute, and tissue death occurs if flow dips below ...
