What are the common causes of a first seizure in teenagers?
A first seizure in teenagers can be caused by epilepsy, head injury, infections, high fever, sleep deprivation, or drug and alcohol use.
Explanation
Teenagers experiencing a first seizure may have various underlying causes, including:
Epilepsy: A common neurological condition causing recurrent seizures. Head injuries: Trauma from sports, accidents, or falls can trigger seizures. Infections: Illnesses like meningitis or encephalitis may cause seizures. High fever: Febrile seizures, while more common in younger children, can rarely occur in teens. Sleep deprivation: Lack of sleep can lower seizure threshold. Drug or alcohol use: Intoxication or withdrawal can provoke seizures. Metabolic imbalances: Low blood sugar or electrolyte disturbances may trigger seizures. Brain abnormalities: Structural issues like tumors or malformations. Stress: High emotional or physical stress can be a factor.
If a teenager has a first seizure, prompt medical evaluation is important to diagnose the cause and guide treatment.
