Mothballs

I have been increasingly concerned about mothballs in the homes of loved ones. I need to find a way to lovingly and firmly convince people that, if a home reeks of mothballs, the residents of that home are slowly being poisoned.

I have only just started my research on this topic, so I don't have much to go on yet.

Here is a brief overview, but I need to find some scientific studies to back up this information.

If anyone has any information, please post here or feel free to contact me. I am mostly interested in how inhalation of mothball fumes may simulate symptoms of dementia in elderly humans.
