Is it true that parasites and worms can cause depression?
Most definitely. I’ve seen depression disappear many times when parasites and worms are eliminated. It is well documented today that fungus or candida overgrowth causes depression, and it’s the same for many other invaders such as parasites (especially the blood parasite), worms, infectious bacteria, and mould. Depression can be caused by many other factors and not all depression disappears when invaders are gone. It really depends on the cause of the depression.
