Generally, it causes functional changes first. When the concentration (intensity) and action time of harmful factors exceed a certain limit or the functional changes develop to a certain extent, organic lesions will appear.Organic lesions are often irreversible changes.
"Functional" diseases, generally speaking, are caused by organsnervous systemClinical syndrome caused by maladjustment ofNeurosis, although it can have headache, dizziness, weakness, insomnia and other symptomsBrain cellNo material damage,CTThe scanning tissue is normal, and there is no abnormal change of brain structure under the microscope.
Of course, the difference between the two is not absolute, the condition can be transformed into each other.For example, simplicityhypertensionAt the initial stage, the increase of blood pressure is simple, and the heart, brain, and kidney are not involved. At this time, it is functional;However, if the blood pressure continues to rise without treatment or cannot be controlled well despite treatment, and substantial damage is caused to the heart, brain, kidney and other organs, then the hypertension will become an "organic" disease.[1]
