Researchers have shown that an electric shock ranging from 120 to 52,000 volts can cause neurologic and neuropsychological symptoms in humans. Following an electrical injury, some patients may show various emotional and behavioral aftereffects, such as memory loss and symptoms of depression.
Can an electric shock damage your brain?
When a shock occurs, the victim may be dazed or may experience amnesia, seizure or respiratory arrest. Long-term damage to the nerves and the brain will depend on the extent of the injuries and may develop up to several months after the shock. This type of damage can also cause psychiatric disorders.
What are the psychological effects of electric shock?
General effects of electric current
|Electric current (contact for 1s)||Effect|
|Below 1 mA||Not perceptible|
|1 mA||Threshold of feeling, tingling|
|5 mA||Slight shock. Not painful. Average individual can let go. Involuntary reaction can lead to indirect injuries|
|6-25 mA (women)||Painful shocks. Loss of muscle control|
What are the long-term effects of electric shock?

Can electric shock cause neurological problems?
Electrical shock can result in neurological complications, involving both peripheral and central nervous systems, which may present immediately or later on. However, delayed neurological complications caused by low-voltage electric shock are rarely reported.
When should I go to the doctor for electric shock?
