Prevalance of Epilepsy:

Epilepsy affects approximately 1% of the population making it one of the most common neurological diseases. (Source: Genes and Disease by the National Center for Biotechnology)

    Epilepsy: Causes and incidence
    (Professional Guide to Diseases (Eighth Edition))

    In about half the cases of epilepsy, the cause is unknown. However, some possible causes of epilepsy include:

    ❑birth trauma (inadequate oxygen supply to the brain, blood incompatibility, or hemorrhage)

    ❑perinatal infection

    ❑anoxia (after respiratory or cardiac arrest)

    ❑infectious diseases (meningitis, encephalitis, or brain abscess)

    ❑ingestion of toxins (mercury, lead, or carbon monoxide)

    ❑tumors of the brain

    ❑inherited disorders or degenerative disease, such as phenylketonuria or tuberous sclerosis

    ❑head injury or trauma

    ❑metabolic disorders, such as hypoglycemia or hypoparathyroidism

    ❑stroke (hemorrhage, thrombosis, or embolism).

    Alcohol withdrawal can cause nonep-ileptic seizures.

    Epilepsy affects 1% to 2% of the population. However, 80% of patients have good seizure control if they strictly adhere to the prescribed treatment regimen.

    Seizures - Case 19-1: 8-Day-Old Girl: III. Incidence and Epidemiology
    (Pediatric Complaints and Diagnostic Dilemmas)

    L. monocytogenes, a motile gram-positive rod, was first isolated in 1926 during an investigation of epidemic perinatal infection among a colony of rabbits. It is a common veterinary pathogen that causes meningoencephalitis in sheep and cattle. It is widespread in the environment and is found commonly in soil and decaying vegetation. Many foods are contaminated with this organism; it has been recovered from raw vegetables, fish, poultry, unpasteurized milk, and certain types of cheese. The organism has been isolated from the stools of 5% of healthy adults, and higher rates of recovery have been reported for household contacts of patients with clinical infection. Infection in humans is uncommon but occurs most frequently in neonates, pregnant women, and elderly or immunosuppressed patients. Approximately 30% of all L. monocytogenes infections occur in neonates.

    Seizures - Case 19-2: 10-Day-Old Boy: III. Incidence and Epidemiology
    (Pediatric Complaints and Diagnostic Dilemmas)

    Hyperparathyroidism has a prevalence rate of 0.15%, with a peak incidence between 30 and 50 years of age. Approximately 80% of cases are due to a solitary adenoma that requires resection, and 15% are due to chief cell hyperplasia. Maternal symptoms are not apparent until the serum calcium level exceeds 12 to 13 mg/dL. However, even mild maternal hypercalcemia leads to chronic fetal hypercalcemia, which in turn suppresses fetal production of PTH. After birth, calcium levels decrease but PTH production cannot be rapidly increased. In this condition, neonatal hypoparathyroidism is transient, lasting only several days to several weeks. Eventually, as the parathyroids become more active, increasing PTH levels stimulate vitamin D production and extra calcium absorption from the plentiful supply in the gut. Clinically detectable hypocalcemia develops in 15% to 25% of infants born to mothers with hyperparathyroidism. As in this case, neonatal seizures or tetany often leads to a search that identifies a maternal parathyroid adenoma.

    Seizures - Case 19-3: 8-Month-Old Boy: III. Incidence and Epidemiology
    (Pediatric Complaints and Diagnostic Dilemmas)

    The GSDs, or glycogenoses, comprise several inherited diseases caused by deficiency in one of the enzymes that regulate the synthesis or degradation of glycogen. The end result is abnormal accumulation of glycogen in various tissues. GSD type I has an estimated incidence of 1 in 200,000 births. GSD IA is caused by deficiency of the enzyme G6P, which catalyzes the breakdown of stored glycogen into glucose for use by the body. At least 56 different mutations in the gene for G6P (chromosome 17q21) have been found in patients with GSD IA. Failure of the G6P transporter (GSD IB) or of the microsomal phosphate transporter (GSD IC) also ultimately impair G6P activity. The three types of GSD result in similar clinical and biochemical disturbances. G6P is expressed in the liver, kidneys, and intestines.

    About prevalence and incidence statistics:

    The term 'prevalence' of Epilepsy usually refers to the estimated population of people who are managing Epilepsy at any given time. The term 'incidence' of Epilepsy refers to the annual diagnosis rate, or the number of new cases of Epilepsy diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
