“…However, age does not seem to be an important factor (no difference with presbyacusis or tinnitus). Furthermore, female predominance was also found in the much younger sample reported by Penfield and Perot [7], With regard to the intervention of a mediating variable there is no evidence that epilepsy (17,18], deafness [19], tinnitus [4,20] or brain tumours [21 -24] arc more prevalent in females: nor that auditory hallucinations are more frequent in females with schizophrenia at any age [25,26], However, a predominance of females in a group of elderly individuals with visual hal lucinations has been reported [15]. Thus fe males may experience (or report) hallucina tions related to organic states more often than males.…”

Musical hallucinations remain rare, are more common in women, and their onset is often related to ear pathology, particularly deafness. When brain disease is involved, pathology of the right or non-dominant hemisphere seems overrepresented. Psychosis and personality traits play a minimal role in their development. A discriminant function was constructed that correctly predicted the presence of brain disease (89%) and included the following clinical variables: being male, having acute onset musical hallucinations, and absence of deafness, psychiatric disease, and other forms of hallucination.

“…Most reviews of the epidemiology of epilepsy have commented on the wide range of prevalence figures obtained as a result of using differing methodologies and a variety of definitions of epilepsy [20]. In spite of this lack of consistency in results, there has emerged a consensus of opinion which has accepted a 1/200 prevalence ratio for developed countries.…”

“…While some reports have based their assessment on 2 or more seizures [20], this fails to consider adequately the term 'tendency to recurrence' which is quoted in a number of the definitions [8,12], It was felt that more than 2 seizures were required, a stance supported by Zielinski [10]. Further, to include the wide variety of manifestations of seizures, professional diag nosis was necessary.…”

An Accurate Assessment of the Prevalence Ratio of Epilepsy Adequately Adjusted by Influencing Factors

1985

The prevalence of epilepsy was estimated by defining an initial prevalence ratio based on a population study and modifying this figure on the basis of various factors which influenced it. The definition required 3 seizures diagnosed by a doctor and the influencing factors included false-negative responses (where the diagnosis was confirmed), false reporting (where the diagnosis had not been established) and falsely low seizure counts (where therapy had reduced the number of seizure below the mandatory 3). As a result of these calculations the figure of approximately 1 in 50 was offered as a reliable and reasonable estimate of the true prevalence ratio of epilepsy within a well-defined Australian population.

“…Another possibility is that these people would develop more seizures if enough time was given, so that they might not be any different from those with multiple seizures. Also, since many are treated with anticonvulsants after one seizure, they might not be having further seizures because they are protected (Neugebauer and Susser, 1979). On the other hand, if one includes them, then the assumption is made, perhaps erroneously, that the risk factors are similar for single and multiple seizures.…”

Perinatal Factors and Seizure Disorders: An Epidemiologic Review

In this review, we assess the following six aspects of the epidemiological literature addressing the association between perinatal factors and seizure disorders (mainly of the grand mal type): (1) study design; (2) selection of cases; (3) selection of controls; (4) definition and ascertainment method of seizures; (5) definition and ascertainment method of perinatal factors; (6) sample size and power. Needed are studies of perinatal factors in a homogeneous group of seizure patients, such as those with grand mal seizures. Because of the rarity of the seizure disorder, most follow-up studies of this subject suffer from inadequate sample size. Improvements are suggested for case-control studies, which appear, by necessity, to be the more appropriate design.
