A five-year-old Labrador named Tokyo became critically ill on Scotland’s Ben Nevis after allegedly ingesting cannabis left on the trail. Lochaber Mountain Rescue Team carried the dog down the mountain and she was treated at a nearby vet, making a full recovery the next day. The owner urged vigilance about discarded drugs in outdoor areas.
A comprehensive April 2026 review of nearly 300 studies finds chlorpyrifos causes widespread harm beyond its well-known neurotoxic effects, including damage to the brain, hormones, liver, gut microbiome, muscles, reproductive organs, and bones, plus DNA damage and lasting epigenetic changes. Some adverse effects occur at exposure levels below current safety thresholds, with fetuses and young children especially vulnerable. Regulators may not fully capture these risks in testing, prompting calls for independent research, stronger protections for pregnant people and children, and a reassessment of industry-sponsored studies as the EPA reevaluates remaining uses of the pesticide.
A recent study highlights the neurotoxic effects of PFAS chemicals, commonly found in everyday products and contaminated water, showing they can accumulate in the brain and impair memory, behavior, and cognitive functions, raising concerns about long-term health impacts and the need for stricter regulations.
Hannah Schweickert experienced severe side effects, including numbness and panic attacks, after taking high doses of Adderall for ADHD. Her symptoms persisted even after stopping the medication, and she suspects neurotoxic effects based on animal studies. The case highlights potential risks of stimulant medications like Adderall, which are widely prescribed to children and adults for ADHD.
A new study suggests that leaded petrol may have negatively impacted the mental health of millions of Americans. The research highlights the potential long-term effects of lead exposure on cognitive and psychological well-being, emphasizing the importance of understanding environmental factors in public health.
A recent study reveals that exposure to leaded gasoline has significantly impacted the mental health of Americans, with an estimated 151 million cases of psychiatric disorders linked to lead exposure from car exhaust. The research highlights that individuals born before 1996, particularly during the 1960s and 1970s, experienced higher rates of mental health issues due to lead's neurotoxic effects. Despite the 1996 ban on leaded gasoline, the legacy of lead exposure continues to affect public health, prompting ongoing efforts to mitigate its impact.
A study in the Journal of Child Psychology and Psychiatry links mental health issues in Generation X to childhood exposure to lead from leaded gasoline. Researchers estimate that over half of the U.S. population was exposed to neurotoxic levels of lead, contributing to 151 million cases of psychiatric disorders over 75 years. The study highlights the significant impact of lead on brain development and mental health, though it does not establish causation and focuses solely on gasoline-related exposure.
Florida Surgeon General Joseph Ladapo has called for an end to water fluoridation in the state, labeling it "public health malpractice" due to potential neurotoxic effects, particularly in children and pregnant women. This stance contradicts the CDC and major health organizations, which endorse fluoridation for its dental health benefits. The Florida Department of Health has issued guidance against fluoridation, citing studies linking high fluoride exposure to lower IQs and other neurobehavioral issues. Critics argue these studies are based on data from countries with higher fluoride levels than the U.S.
A study published in Nature reveals that APOE4 exacerbates the formation of lipid droplets in microglia, particularly in individuals with Alzheimer's disease. This lipid accumulation is linked to the overexpression of an enzyme involved in triglyceride synthesis, and APOE4/4 microglia were found to release neurotoxic substances, potentially including the triglycerides themselves. The study suggests that APOE4/4 microglia may be detrimental to neurons and could play a role in the progression of Alzheimer's disease.
Dr. Elizabeth Landsverk discusses how alcohol affects the body differently as we age, with younger individuals having more resilient livers and brains, but potentially setting harmful habits. In middle age, alcohol can exacerbate health issues like obesity, diabetes, and hypertension, increasing the risk of heart attacks and strokes. As people reach their 50s and 60s, the body's ability to metabolize alcohol declines, leading to increased risks of cancer, dementia, and other health problems. Landsverk advises moderation, comparing alcohol to a candy bar that shouldn't be consumed with every meal due to long-term health risks.
Researchers from UCLA and Harvard have identified 10 pesticides that significantly harm neurons implicated in Parkinson’s disease, using California’s pesticide database to find pesticides toxic to dopaminergic neurons. The research uncovered 53 pesticides potentially linked to Parkinson’s, with a particular blend used in cotton farming showing increased toxicity. Future research will focus on the biological disruptions caused by these pesticides in Parkinson’s patients.
