How is goat madness caused?
modern medical research has proved that sheep madness is a chronic disease caused by sudden abnormal discharge of brain neurons, which leads to temporary brain dysfunction. The sheep crazy attack refers to the clinical phenomenon caused by abnormal brain neurons and excessive supersynchronization discharge. Due to the different parts of abnormal discharge neurons in the brain, the symptoms are various.
In daily life, sheep madness has other names: epilepsy or epilepsy, which was recorded in ancient Chinese as early as 2, years ago. People are no strangers to this disease, which is often popularly called "convulsion". "convulsion" often indicates two meanings: one is the state of real disease, which is caused by excessive discharge of brain neurons, and the other is to describe someone's irregular, abnormal, irrational and uncontrollable behavior.
In addition, those who are asymptomatic in clinic and only have abnormal discharges on EEG are not called sheep crazy attacks. Because sheep madness is a brain disease, abnormal and excessive discharge of neurons in other parts of the body (such as trigeminal neurons or spinal cord anterior horn neurons) does not belong to sheep madness.
Reasons
Experts from Chengdu Shenkang Epilepsy Hospital have summarized the causes of the following kinds of sheep madness through a large number of clinical studies:
Sheep madness is a chronic brain disease caused by abnormal high-frequency discharge of local neurons in the brain. Modern medicine believes that the causes of sheep madness can be divided into two categories: primary (functional) sheep madness and secondary (symptomatic) sheep madness.
1. Primary sheep madness
Primary sheep madness is also called true or idiopathic or cryptogenic sheep madness. Through the clinical diagnosis and treatment records, we found that there is an obvious relationship between primary sheep madness and family history, and it is necessary to make a detailed consultation on the patient's family history when making a diagnosis.
Second, secondary sheep madness is also called symptomatic sheep madness. Refers to sheep madness that can find the cause. See the following common causes.
according to the seizure situation, it can be divided into localized seizures, psychomotor seizures, minor seizures, major seizures and complex partial seizures.
(1) Localized seizures, which are generally seen in patients with organic cerebral cortex damage, are characterized by paroxysmal twitches or sensory abnormalities of one side of the mouth, fingers or toes, and can spread to one side of the body. When the attack involves both sides of the body, it can be manifested as a large attack.
(2) Psychomotor seizures (also known as complex partial seizures) can be manifested as sudden seizures, confusion, irregular and uncoordinated movements (such as sucking, chewing, searching, shouting, running, struggling, etc.). The patient's actions are unmotivated, aimless, blind and impulsive. The attack lasts for several hours, sometimes for several days, and the patient has no memory of the attack.
(3) Small seizures, which may cause temporary (5-1 seconds) disturbance or loss of consciousness, without general spasm. There may be multiple attacks every day, and sometimes there may be rhythmic blinking, bow head, eyes looking straight, and upper limb twitching.
(4) grand mal, also known as generalized seizure, half of them have premonitions, such as dizziness, insanity, epigastric discomfort, audio-visual and olfactory disorders. During the seizure (seizure period), some patients first make a sharp cry, then fall down after losing consciousness, with whole body muscle rigidity and breathing pause, and the head and eyes can be tilted to one side. After a few seconds, there is clonic convulsion, and the convulsion is gradually aggravated, which lasts for tens of seconds. During the clonic period, breathing resumes and foaming at the mouth (such as blood foam appears when the tongue is bitten). Some patients have incontinence, body relaxation after convulsion or enter lethargy (lethargy period), and then consciousness gradually recovers.
seizure symptoms
A spasm of rigidity is characterized by loss of consciousness and general convulsion, which shows continuous contraction of skeletal muscles, strong extension of limbs, eyeball inversion, apnea, throat spasm, screaming, clenched teeth and loss of consciousness. After about 1 ~ 2 seconds, continuous, short and violent generalized flexion spasm appears, and the frequency of clonus gradually slows down to stop after reaching the peak, generally lasting for 3 seconds to 1 minute. After clonus stops, there is a muscle retardation period of 5-8 seconds, breathing resumes first, heart rate, blood pressure and pupils return to normal, incontinence can be found, and consciousness is fully recovered in 5-1 minutes. Many patients turned into a lethargic state after the disturbance of consciousness was relieved, and a few showed signs of automatism and wandered around.
As a short-term loss of consciousness (usually 2-15 seconds), typical absences are common in children. Absence occurs suddenly, with sudden suspension of activities, language interruption, eyes staring, eyes rolling up occasionally, sometimes pale, with little warning, and some may fall down with myoclonia and disappearance of muscle tension. Because the attack time is short, it is often ignored by parents for a long time.
In addition to disturbance of consciousness, some seizure types may be accompanied by hallucinations, delusions, mental disorders and memory disorders. Others lose consciousness, showing only local convulsions, abnormal sensation, and even periodic and repeated symptoms such as headache and abdominal pain. A few cases are stimulated by sight, hearing, smell and spirit only under certain conditions.
