Moreover, depression, which may increase cognitive difficulties, can be compounded by 28. Epilepsy Surgery: Factors That Affect Patient Decision Making in Choosing or Deferring a Procedure. Outcome of temporal Epilepsy is already very common in the older population and the incidence will rise as populations age. Diagnosis can be difficult but, as for all epilepsy, rests on securing a detailed history. Outcomes after resective epilepsy surgery in patients over 50 years non-contributory and occasionally confusing.

A survey of epileptic disorders in southwest France: seizures in elderly patients. Sodium valproate can also stimulate appetite leading to obesity, as can vigabatrin, gabapentin and pregabalin. The occurrence of these side effects, which are mostly undesirable in all, can have a particularly detrimental effect during adolescence. Female hormones may also affect seizure threshold, resulting in increased frequency of seizures at certain times of the menstrual cycle. Hormonal alterations, including changes in prolactin, follicle-stimulating hormone and luteinising hormone have been observed following generalised and focal seizures1. They are thought to arise as a result of connections between the hypothalamic-pituitary axis and areas of the brain involved in seizures, although the precise mechanisms are unclear1–3. Many of the problems An increase in seizure frequency around the time of menstruation (catamenial epilepsy) was frst clinically of tolerance, in particular those of benzodiazepines, can be overcome using this treatment model. In documented by Gowers in 1881 but cyclical variations in seizure frequency have been known about since a double-blind crossover study of 20 mg clobazam versus placebo over a predetermined ten-day period in antiquity and were initially attributed to the cycles of the moon. There is no agreement on the degree of seizure exacerbation required to meet a defnition of catamenial epilepsy. However, many of these With regard to therapy it should frst be established whether the seizures are truly catamenial, and the studies are poorly documented, use a less than strict defnition of what seizures to include in the calculation particular subtype of catamenial epilepsy, and that the menses are following a regular pattern23. If so, of perimenstrual attacks and are unrepresentative of the female population with epilepsy. Using the strict intermittent therapy with clobazam 10 mg at night perimenstrually is the simplest and most useful defnition for catamenial epilepsy that 75% of seizures have to occur within four days preceding and therapy for the majority of women. If this fails, it may be worth considering the use of acetazolamide within six days of the onset of menstruation, Duncan et al showed that only 12. However, 31 (78%) claimed that most of their seizures occurred around the time of menstruation. However, good evidence for the effectiveness of these therapeutic options is lacking. Human data tend to support this hypothesis, although there appear to be no clear Fertility differences in hormonal changes in women with and without catamenial seizures7. The potential reasons for this are allopregnanolone withdrawal at the time of menstruation (day 25 of the outgoing cycle to day 3 of new likely to be complex, and include social and economic factors. It has also been reported that sexual cycle) provide one possible mechanism for exacerbation of seizures perimenstrually (which is the most arousal may be reduced in women with epilepsy. However the situation is far from resolved, with other common type of catamenial seizure exacerbation), although other mechanisms have also been suggested8. The second most common pattern observed is the periovulatory pattern, where increased seizure frequency It is recognised that there is a high incidence of menstrual disorders among women with epilepsy26. Anovulatory cycles tend to be 35% of women with partial seizures of temporal lobe origin had anovulatory cycles when studied over associated with higher seizure frequencies, in particular during times of peak oestrogen concentration10. Treatment has been tried with progesterone suppositories Anovulatory cycles tend to be associated with an increase in seizure frequency in the second half of the in the appropriate phase of the menstrual cycle 28, as well as clomiphene24, and medroxyprogesterone17, menstrual cycle while ovulatory cycles can have one or two peaks in seizure frequency, at around the time with some success. A recent prospective study showed that women with epilepsy have an increased risk of infertility, Other infuences around the time of menstruation, such as premenstrual tension and mood changes, may particularly if they are using polytherapy. In 1993, Isojarvi reported that polycystic ovaries and Over the last century many therapeutic agents have been tried with various degrees of success. Subsequently they reported that these introduced bromides in 1857 for the treatment of catamenial and hysterical epilepsies. By the turn abnormalities are more common in women on valproate who gain weight31, especially if this is during of the century it had been noted that seizure frequency occasionally decreased at the menopause or pubertal maturation32. However, their initial study was retrospectively based in a selected population and after oopherectomy. In the 1950s acetazolamide became available, which is advocated by some for use did not concentrate on clinical endocrine status.
