How long does brain dysfunction take to recover?

The recovery time of brain dysfunction varies from person to person, and also varies from acute to chronic. Acute brain dysfunction can be recovered quickly, such as hypoglycemia encephalopathy. If blood sugar is corrected, the patient may recover in 5-10 minutes, or it may take a long time. For example, some patients with hypoglycemia encephalopathy recover slowly during correction, or 3-5 days, or even cannot be corrected, and there is a possibility of death. Hypoglycemic encephalopathy occurs because most of the causes are due to diabetes patients in the treatment of diabetes, long-term large or excessive use of insulin, excessive reduction in blood sugar, resulting in hypoglycemic encephalopathy. Hypoglycemic encephalopathy occurs, especially in elderly patients must be corrected quickly, such as drinking sugar water, eating fruit, eating food, or in the hospital must be transfused glucose, or push glucose to relieve symptoms. Hypoglycemic encephalopathy is a serious hazard. In normal life, we must pay attention to blood sugar adjustment. Blood sugar should not be too high, but it should not be too low. Blood sugar has a normal range, such as fasting blood sugar in 4.4-6mmol/L, 2 hours after meal blood sugar in 4.4- 7.8 mmol/L, generally not lower than 4.4 mmol/L, if lower than 4mmol/L, there is a risk of hypoglycemia, if lower than 2.8 mmol/L, there is a risk of hypoglycemia encephalopathy. Therefore, we must pay attention to blood sugar adjustment, if hypoglycemia symptoms occur, to reduce oral medication or insulin, once the consequences of hypoglycemia encephalopathy sometimes very serious.
