Hyperthermia from neurological disease may include little or no sweating, cardiovascular problems, and confusion or delirium. Other signs and symptoms vary. Accompanying dehydration can produce nausea, vomiting, headaches, and low blood pressure and the latter can lead to fainting or dizziness, especially if the standing position is assumed ...
Heavy sweating causes heat cramps, especially when the water is replaced without also replacing salt or potassium. [2] Although heat cramps can be quite painful, they usually don't result in permanent damage, though they can be a symptom of heat stroke or heat exhaustion. Heat cramps can indicate a more severe problem in someone with heart ...
The pathophysiology of heat stroke involves an intense heat overload followed by a failure of the body's thermoregulatory mechanisms. More specifically, heat stroke leads to inflammatory and coagulation responses that can damage the vascular endothelium and result in numerous platelet complications, including decreased platelet counts, platelet ...
Causes: Antipsychotic medication [1] Risk factors: Dehydration, agitation, catatonia [4] Diagnostic method: Based on symptoms in someone who has started on antipsychotics within the last month [2] Differential diagnosis: Heat stroke, malignant hyperthermia, serotonin syndrome, lethal catatonia [2] Treatment
Malignant hyperthermia and malignant catatonia share features of autonomic instability, hyperthermia, and rigidity. However, malignant hyperthermia is a hereditary disorder of skeletal muscle that makes these patients susceptible to exposure to halogenated anesthetics and/or depolarizing muscle relaxants like succinylcholine.

[13] [14] Non-infectious causes include vasculitis, deep vein thrombosis, connective tissue disease, side effects of medication or vaccination, and cancer. [13] [15] It differs from hyperthermia, in that hyperthermia is an increase in body temperature over the temperature set point, due to either too much heat production or not enough heat loss ...
In this study, 75% of the blood products used were related to traumatic injury. Elderly patients are more likely to experience hypovolemic shock due to fluid losses as they have less physiologic reserve. [4] Hypovolemia secondary to diarrhea and/or dehydration is thought to be predominant in low-income countries. [15]
Malignant hyperthermia (MH) is a type of severe reaction that occurs in response to particular medications used during general anesthesia, among those who are susceptible. [1] Symptoms include muscle rigidity , fever , and a fast heart rate . [ 1 ]
