Partial Seizures In High-Income Countries

Good Essays

Seizure disorder affects 65 million people worldwide. The prevalence of active cases of epilepsy vary between high-income and low-income countries likely due to differences in risk factors. High-income countries have a prevalence of 5-8 per 1000 in a population, while low-income countries have a prevalence of 10 per 1000. The risk factors that cause this discrepancy are assumed to be infections and inadequate care during and after pregnancy. There is also a vast difference in epilepsy mortality rates between high-income and low-income countries. High-income countries’ mortality rate are only 2-5 times higher than the general population as compared to the low-income countries’ rate of 37 times higher (Fazel et al, 2013).

Partial seizures can be further categorized into simple partial or complex partial seizures. The difference between simple and complex partial seizures whether or not consciousness is preserved or impaired; simple being the former and complex being the later. Another form of partial seizure is the secondary generalized in which it begins as a partial seizure and spreads to both hemispheres. Simple seizures are usually localized in areas of the brain relating to sensorimotor functions. Areas such as the occipital lobe, limbic system, and temporal lobe foci are typically effected resulting in the twitching, jerking, mood and emotion changes, and memory or personality changes characteristic of simple partial seizures. Complex partial seizures include the afore mentioned components but are accompanied by altered states of awareness usually experience as deja u and illusions. The temporal and frontal lobes are the two major areas implicated in these seizures. When a partial simple seizure spreads to both hemispheres it is called a secondarily generalized seizure (Miller et …show more content…

Traumas to the brain are a major risk factor for the development of epilepsy and within the following years after such an injury they are considered high risk for epilepsy. In a study done on the risk of epilepsy after head trauma the following statistics were discovered regarding the rate of development:
The relative risks of epilepsy were raised about two-fold (relative risk 2?2) after a mild head injury and seven-fold (7?4) after a severe head injury, were slightly greater in women than in men, and increased with older age at time of injury. The rate of development of epilepsy was greatest in the few years after the head injury; for instance, with a greater than five-fold increase for 2-3 years after a severe head injury, but the excess risk continued for 10 years after mild and severe brain injury-longer than in other studies (Shorvon, Nelligan 2009).
They also found that those with a family history of epilepsy had a greater risk than those who did not. Those who did not have a family history only had a raised risk of two-fold after a mild injury, while those with a family history had an incredible six-fold. These findings further support the idea that seizure disorders can be caused by multiple factors and the presence of two or more of these factors drastically increases the risk of its development (Shorvon, Nelligan
