That's a really thoughtful question — and a valid one given your years of darkroom work. Darkroom photography involves regular exposure to chemicals like solvents, thinners, and fixers, which fall into a broader category of chemicals researchers have been studying in relation to Parkinson's disease (PD).

Research has found that certain environmental chemical exposures may increase the risk of developing PD, particularly in people who may have a genetic susceptibility. The chemicals most studied include:

- Pesticides (rotenone, paraquat, organophosphorus compounds)
- Solvents and industrial chemicals used in hobbies like woodworking and painting
- Organochlorine compounds (like DDT) Darkroom chemicals such as developers, stop baths, and fixers contain compounds that share similarities with these studied substances. While there isn't a study specifically targeting darkroom photography, the general link between long-term solvent and chemical exposure and PD is worth discussing with your neurologist.

Going forward, some practical precautions if still working with chemicals include:

- Wearing gloves and a mask
- Ensuring good ventilation
- Washing hands thoroughly after any chemical contact

It's definitely worth raising your 20-year darkroom history with your care team — it's useful context for managing your health.
