There is a worrying correlation between environmental change and neurological health, i.e. Brain HealthWriting in the journal The Lancet Neurology, researchers from University College London reviewed hundreds of studies over more than half a century. independent.

Extreme heat is occurring at both poles of the Earth, and scientists are worried: “Temperatures in the Arctic are 30 degrees higher than normal!”
They analysed the impact of extreme weather on 19 neurological conditions, including stroke, Alzheimer’s disease, meningitis, epilepsy and multiple sclerosis. They also looked at common severe psychiatric disorders such as anxiety, depression and schizophrenia, and found “clear evidence for climate impacts on some brain disorders, particularly stroke and neurological infections”.

“Changes in climate that have been shown to affect brain disease include extreme temperatures, both low and high, and greater temperature variability during the day, particularly when these measures are seasonally abnormal,” said Professor Sanjay, director of genomics at UCL’s Epilepsy Society. He added that nighttime temperatures may have a particular impact because warm nights disrupt sleep.
– It is well known that lack of sleep worsens many brain diseases- said Dr Sisodia.
As heat waves become longer, billions of people around the world are sleeping in warmer-than-normal temperatures. Researchers have noted an increase in hospital admissions, disability or death due to stroke during higher ambient temperatures or heat waves. In short, it has become urgent to study and understand how extreme heat affects our health, as rising global temperatures are breaking records.
Asia has been hit by a heatwave in the past few weeks, which scientists are now attributing to the climate crisis. April this year was the hottest April on record. Studies have found that 2023 is the hottest year on record, and last summer was the hottest since 2000.
The researchers found that Dementia Exposure to extreme temperatures, whether hot or cold, is at greater risk because cognitive impairments may limit their ability to adapt behaviorally to changes in their environment.
– Reduced awareness of risk and reduced ability to seek help or mitigate potential harm, such as fetching more water or adjusting clothing. Dr Sisodia explains that frailty, multiple illnesses and psychotropic medications can increase this sensitivity.
The researchers warn that greater temperature swings and heat waves could lead to an increase in dementia-related hospitalizations and deaths. In addition, they say climate change could make life more difficult for people with anxiety and similar conditions. This could make it harder for us to cope with the impacts of the climate crisis and the changes we need to make to stay healthy.
