Lupus. The ability of so many different types of physical, biological, chemical and mental stressors to induce HO-1 explains why the core symptoms of chronic stress are so similar to CO poisoning regardless of the stressor (see symptoms, below). Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Dull headache 2. Neuropsychiatric sequelae are a common feature of acute carbon-monoxide (CO) poisoning-particularly when the patient has experienced an episode of CO-induced unconsciousness. This means that the potential for severe permanent brain damage is off missed. 15% of COHb can produce mild headache while Typically chronic carbon monoxide poisoning is thought to involve long term exposure to low levels of carbon monoxide, but that is often not the case. 7 However, the evidence for lasting effects occurring at much lower levels of exposure is poor.
