Barbiturates in the treatment of epilepsy in people with intellectual disability.

Barbiturates are effective drugs in the treatment of epileptic disorder. The systemic side-effects are minimal. The main limiting factor is the presence of cognitive and behavioural problems. Relevant research is presented in this paper; however, it is somewhat difficult to extrapolate some of these experiences to a population of children and adults with intellectual disability and epilepsy. Recent reviews of this subject have suggested that, although the cognitive deficiencies seem to be a serious problem when phenobarbital is given in high doses, the problem is much less severe when the doses are on the low side. The most consistent findings with regard to behaviour are the exacerbation of behaviour disorders (mostly hyperactivity), as well as sleep disorders and depression in individuals who already have a predisposition to these disorders. However, the clinical experience of many professionals involved with the care of people with intellectual disability strongly suggests that barbiturates, and especially phenobarbital, produces intolerable side-effects at the point that the use of phenobarbital has been reduced to a minimum, and it is no longer considered a drug of choice. It is probably that the simultaneous presence of brain damage, epilepsy, intellectual disability and psychiatric disorders in people with intellectual disability is responsible for the high incidence of behaviour problems observed by clinicians.
