Epidemiology A Prevalence and Incidence

Epidemiological studies of epilepsy are often difficult to compare because of different study designs and definitions of epilepsy. Calculated incidence rates of epilepsy range between 20 and 70/100,000 per year. The incidence is age dependent, with a maximum in early childhood and lowest rates in early adulthood. Incidence rates rise again in older age groups, probably due to the higher prevalence of cerebrovascular disease. The overall risk for epilepsy is slightly higher in males than in females. The point prevalence of active epilepsy is of the order of 3-5/1000. The cumulative lifetime prevalence has been estimated to be 3.5%.

There is thus a 10-fold difference between the point prevalence and the lifetime prevalence, suggesting that the disease remains active in only a small proportion of cases. The prevalence of epilepsy is higher in third world countries, with rates of up to 37/1000 in Africa. This is probably related to a higher frequency of infectious diseases of the nervous system diseases such as neurocysticercosis and the higher risk of perinatal complications.

We have all been there: turning to the refrigerator if feeling lonely or bored or indulging in seconds or thirds if strained. But if you suffer from bulimia, the from time to time urge to overeat is more like an obsession.
