AIIMS Patna Study Unravels Brain’s Critical Link In Heatstroke Deaths

A team of researchers at the All India Institute of Medical Sciences (AIIMS) in Patna has made a significant breakthrough in understanding the link between heatstroke and fatalities.

The study published in the Medico-Legal Journal identified a specific brain center and vascular injury patterns that play a crucial role in heatstroke-related deaths.

The research team discovered that the anterior hypothalamus, which serves as the brain's primary temperature-regulating center, undergoes severe structural damage during heatstroke. This damage is found to be a key factor in the fatal outcomes associated with heatstroke.

“The study establishes that the anterior hypothalamus undergoes critical structural damage during heat stroke, making it a central driver of fatal outcomes. The injury in the hypothalamus can be used as definitive evidence in the forensic diagnosis of heat-stroke deaths,” said lead author Dr Ashok Kumar Rastogi, forensic expert, in a statement. 

The finding can be a major step forward in the scientific basis for diagnosing heat stroke deaths through post-mortem examination, an area that has often posed challenges for autopsy surgeons in establishing a definitive cause of death, the researchers said. 

It will also help address a long-standing medico-legal issue, particularly in the context of compensation, insurance claims, and death benefits for the families of victims.

The study was conducted by the Department of Forensic Medicine at AIIMS Patna in collaboration with the Department of Anatomy and Pathology.

The study was based on detailed post-mortem investigations of individuals exposed to extreme environmental conditions in the Patna region during 2024, including temperatures reaching 48 degrees Celsius, humidity levels up to 95 per cent, and prolonged heat exposure lasting five to eight hours, the Institute said. 

The results also outlined a vascular injury pattern associated with fatal heat stroke, helping build a clearer pathological profile of the condition under extreme heat exposure.

The researchers noted that the findings could strengthen forensic investigations and support more scientifically grounded death certification in suspected cases.

Heatstroke is a medical emergency with a high case fatality rate. The body’s inability to regulate internal temperature and eliminate heat gain in such conditions increases the risk of heat exhaustion and heatstroke. 

Speaking to HealthandMe, Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), explained how heat stroke affects people.

“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored. These are the features of heat stroke,” Dr Vikram said. 

The most vulnerable category for heat-related problems is the extremes of age—the younger children and older adults. The expert noted that younger children may not be able to express their symptoms completely. They may not be able to tell you exactly what they are feeling. 

At the other end, older adults often have multiple health issues—neurological conditions, diabetes, hypertension, and kidney problems. 

Try to avoid exposure to extreme heat as much as possible. 

One must cover the head and upper body, use an umbrella, stay hydrated, and take breaks in between.

If you have to work in a hot environment for a couple of hours, take a break in a cooler or temperature-controlled environment for at least half an hour before resuming, rather than continuously working in the heat.
