What Are the Causes of Convulsions?
There are physiological and pathological factors for convulsions of hands and feet. Physiological factors are more common, usually occurring in winter due to cold stimulation of the nerves. Prolonged pressure on hands and feet can also cause finger convulsions. Pathological factors are unconscious nervous manifestations that may be related to brain nerves. Brain nerves become abnormal only when they are damaged or in the presence of brain diseases, so a brain CT scan is required. Here are some possible reasons:
Epileptic seizures can occur in winter due to cold stimulation and other disease factors such as fever, colds, convulsions, various bacterial infections, food poisoning, gas poisoning, etc. These factors may stimulate the brain, leading to abnormal brain discharges and inducing epilepsy.
Head injuries, nutritional and metabolic diseases are also causes of epilepsy. Prolonged brain damage caused by coma increases the likelihood of seizures. Vitamin B6 deficiency and metabolic diseases can also contribute to epileptic seizures.
Prenatal and perinatal diseases often lead to a high incidence of epilepsy. Factors such as congenital hydrocephalus, incomplete brain development, birth injuries, difficult births, bacterial infections, and drug stimulation can all lead to frequent epileptic seizures.
Brain diseases are an important cause of high epileptic seizure rates. Common brain diseases such as parasitic infections, cerebrovascular diseases, hydrocephalus, brain atrophy, brain tumors, meningitis, and other brain diseases often occur concurrently with epilepsy, which is one of the reasons for the high incidence of epilepsy.
Calcium ions play an important role in muscle contraction. When the concentration of calcium ions in the blood is too low, the muscles are easily excited and contract abnormally. Calcium deficiency-induced convulsions are particularly common, especially among adolescents, and attention should be paid to calcium supplementation methods.
During intense exercise, the body is in a state of tension, and the leg muscles contract rapidly. If the relaxation time is too short, local metabolites such as lactic acid increase, making it difficult to coordinate muscle contraction and relaxation, which can lead to calf muscle spasms.
