VC, a 26-year old fashion designer, is full of life. Everything is apparently fine with her but for the occasional convulsions she experiences. She gets confused after most episodes of seizures. This is in addition to the bruises she sustains. She convulsed while she was being proposed to. She had been avoiding medications to prevent seizures.
What is a seizure? Seizures are involuntary abnormal changes in behaviour of the affected individual due to erratic electrical discharges in the brain. It can occur in any age group, and affects both sexes. The stigma it causes makes persons who have recurrent seizures to be withdrawn. Some even deny its existence. The denial is more of a problem than the disease itself because the affected person will only seek attention if the condition had been acknowledged.
Any individual who experiences seizures needs to be evaluated closely to identify the cause. If the exact cause is found, appropriate treatment makes the person better. He or she may not have another seizure especially if only one episode had been observed. Individuals who have recurrent episodes of seizure are regarded to have seizure disorder.
What are the common causes of seizure? Some cases of seizures are temporary, meaning that once the cause is identified and managed appropriately, the individual may not have another episode of seizure. Some cases are recurrent.
- Infections: Severe malarial infection as found in cerebral malaria may cause seizure. Bacterial, fungal, and also viral infections affecting the brain can cause seizure as a manifestation of the disease. In small children between 6 months and 5 years of age, elevated body temperature may also cause seizure. With appropriate treatment, the individual may not have another episode of seizure in his/her lifetime.
- Brain injury. Some individuals experience seizures later in life as a result of injury sustained during birth leading to poor oxygen supply to the brain. Brain damage from severe jaundice in the first four weeks of life may also cause some irreversible changes in the brain that result in seizures later in life. Physical injury to the brain sustained during accidents may cause seizure in the future.
- Brain tumours: Some cancers involving the brain may have seizure as one of the symptoms the individual experiences.
- Metabolic diseases: Some rare medical conditions are characterized by poor metabolism of nutrients, especially carbohydrates and lipids. Seizure may be one of the symptoms of these rare diseases.
- Withdrawal state of drug abuse: The brain of persons who abuse illicit drug is most times in a state of apparent quiet depending on the particular drug that is abused. Inability to use the drugs over a period of time results in what is called withdrawal symptoms. These symptoms may include seizures.
- Stroke: Having suffered shortage of blood supply, parts of the brain may later in life give abnormal electrical discharges manifesting as seizures.
