Understanding the Possible Causes of Seizures -- An Overview
There can be number of reasons why someone has a
seizure. In fact, anything that disturbs the normal pattern of nerve cell activity in the brain -- from illness to abnormal brain development -- can cause
seizures.
Some possible causes of seizures may include:
- Fever
- Chemical imbalance
- Medical conditions
- Trauma
- Developmental problems
- Poisoning.
In about half of all seizure cases, the cause is not known.
Many young children experience convulsions that are caused by fevers, called
febrile seizures. During a febrile seizure, a child often loses consciousness and shakes, moving limbs on both sides of the body. Less commonly, the child becomes rigid or has twitches in only a portion of the body, such as an arm or a leg, or only on the right or the left side.
Seizures may be caused by an imbalance of body fluids or chemicals, such as low blood sugar in people with
diabetes, or by alcohol or drug withdrawal.
