True/miasmatic chronic diseases are the diseases that originate from a chronic miasm, which is a dynamic infection that affects the vital force and produces a morbid disposition in the organism. There are three primary miasms: psora, sycosis, and syphilis. These miasms are the fundamental causes of all chronic diseases.

False chronic disease are the diseases that patients bring upon themselves because of prolonged and continual exposure to the avoidable maintaining causes. False chronic diseases are not true chronic diseases because there is no chronic miasm in the background. These are also called as pseudo chronic or inappropriately named chronic diseases.
