Exposure to various toxic agents can lead to syncope. These agents may include:
Carbon monoxide poisoning, which impairs oxygen delivery to tissues, including the brain. Cyanide, a potent inhibitor of cellular respiration, can cause rapid loss of consciousness. Alcohol and other central nervous system depressants, which can disrupt normal brain function. Organophosphates, commonly found in pesticides, which can inhibit acetylcholinesterase and lead to neurological symptoms. Overdose of opioids, which can cause severe respiratory depression and hypoxia.
