Description
Technical field
The present invention relates to the device in a kind of electronic medical instruments technical field, particularly a kind of anxiety, depression and insomnia bipolarity constant current therapeutic instrument.
Background technology
Insomnia is the state that maybe cannot keep sleeping of cannot falling asleep, and causes not having enough sleep.Show as that difficulty falling asleep, Depth of sleep or frequency are too short, early awakening and the length of one's sleep not enough or of poor quality etc., thus cause the feeling of fatigue of people, uneasiness, general malaise, listless, delay of response, headache, the symptom such as absent minded, bring painful and psychological burden greatly to patient.Anxiety disorder also known as anxiety neurosis or anxiety disorder, the mental disorder of main clinical manifestation that to be a group with anxiety be; Comprise panic disorder, social anxiety disorder, obsessive-compulsive disorder, generalized anxiety disorder, posttraumatic stress disorder etc.Depressive disorder is low for main clinical characteristics with remarkable and lasting mental state, and mental state is low unbecoming with its situation, and clinical manifestation, from depressed to extremely grieved, even occurs numb, can have obvious anxiety and mobility intense; The psychotic symptoms such as hallucination, vain hope can be there is in severe patient.
Research display, modal disease altogether of having a sleepless night is anxiety and depression obstacle, insomnia is two-way with the relation of depressive anxiety: in difficulty falling asleep type insomniac, anxiety neurosis is very common, wherein there is depressive symptom in 20% insomniac, and 75% generalized anxiety disorder patient exists insomnia, there is dyskoimesis in 65% depressive patient; On the other hand, anxiety symptom can be predicted future and may occur insomnia, and depressed or depressive symptom is one of the biggest factor causing having a sleepless night.Compare with without insomniac, the risk that insomniac suffers from depressive disorder and anxiety disorder is 9.82 times and 17.35 times without insomniac respectively, and the ratio of insomnia degree higher trouble anxiety disorder is higher.
