Pesticides
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
I work around chemicals and I think they might be affecting my thinking. Can we look at whether my exposure history explains the fog?
What would weaken it
- -No real exposure history or no timing link between the chemical and the symptoms.
- -Symptoms that fit sleep apnea, migraine, anxiety, or medication effects better than toxic exposure.
- -No improvement at all when the suspected exposure is removed.
Key points to communicate
- •I want to name the product or setting involved instead of using vague chemical language.
- •If this doesn't look like a toxic exposure pattern, tell me what more likely category it belongs to.
- •If further testing is needed, I want to know what it would meaningfully change.
Bring this to the visit
- •Occupational and residential exposure history: types of pesticides, duration, protective equipment.
- •Any prior cholinesterase levels or heavy metal testing.
- •A timeline of cognitive symptoms relative to exposure events.
- •Geographic and occupational details: farming, golf courses, pest control, home spraying.
Useful screening structure
- -Serum cholinesterase (butyrylcholinesterase) for organophosphate exposure.
- -Urine organophosphate metabolites if acute exposure is suspected.
- -Neurobehavioral testing if chronic low-level exposure is the concern.
Tests and measurements to discuss
Toxicant Exposure Panel (if high suspicion)
Questions to ask directly
- •Is my exposure level clinically significant based on my history?
- •Should we test for specific pesticide metabolites or cholinesterase?
- •Would removing the exposure source be sufficient, or do I need active treatment?
- •Is there overlap with other toxic exposures I should test for?
Functional impact snapshot
- -Track cognitive function relative to known exposure events or seasonal application.
- -Rate whether symptoms improve during extended periods away from the exposure source.
- -Note specific cognitive deficits: attention, memory, processing speed.
Escalate instead of self-managing if
- •Acute organophosphate symptoms: excessive salivation, lacrimation, urination, defecation, muscle fasciculations.
- •Seizures, respiratory difficulty, or severe confusion after pesticide exposure - medical emergency.
- •Progressive peripheral neuropathy in the setting of chronic exposure.
