Functional headache, also known as psychogenic headache. It is commonly seen clinically in neurasthenia, dysthymia, and depression. These three disorders are also clinically known as neurosis. Although they have a series of neurological and psychiatric symptoms, there is no pathological morphological change in the neural tissue. It is currently believed that the headache caused by such diseases is called functional headache because the patient’s brain is in a state of high tension and fatigue for a long time, which causes the dysfunction of excitation and inhibition of the cerebral cortex. The characteristics of functional headache are: headache generally does not have a certain regularity and the location is not fixed, and it can occur in all parts of the head, but the feeling of heavy pressure at the top of the skull, tightness around the head and distension are more common, and really severe headache is rare. It is often accompanied by insomnia, memory loss, and lack of concentration. Some people may also experience dizziness, blurred vision, panic, shortness of breath, sweating, amenorrhea, impotence and other manifestations of plant nervous dysfunction. Functional headache is caused by the dysfunction of the brain rather than by organic lesions, so it is not harmful. For those who suffer from functional headache, they should treat their headache correctly and do not need to be overly anxious and worried. As long as the work and rest time are reasonably adjusted and arranged, the possible psychological conflicts are resolved, mental tension is avoided, and some medicines are taken appropriately, functional headache can be completely cured.
