“…Photosensitivity is genetically determined. Familial sensitivity to IPS was first described in 1949 [15]. There is no difference in rates of photosensitivity between relatives of nonphotosensitive epileptic subjects and relatives of controls, but photosensitivity is significantly more common in relatives of photosensitive patients.…”

Reflex epilepsy of the visual system is charecterised by seizures precipitated by visual stimuli. EEG responses to intermittent photic stimulation depend on the age and sex of the subject and on how stimulation is performed: abnormalities are commonest in children and adolescents, especially girls. Only generalised paroxysmal epileptiform discharges are clearly linked to epilepsy. Abnormal responses may occur in asymptomatic subjects, especially children. Photosensitivity has an important genetic component. Some patients are sensitive to patterns, suggesting an occipital trigger for these events. Myoclonus and generalised convulsive and nonconvulsive seizures may be triggered by visual stimuli. Partial seizures occur less often and can be confused with migraine. Although usually idiopathic, photosensitive epilepsy may occur in degenerative diseases and some patients with photosensitive partial seizures have brain lesions. Sunlight and video screens, including television, video games, and computer displays, are the commonest environmental triggers of photosensitive seizures. Outbreaks of triggered seizures have occurred when certain flashing or patterned images have been broadcast. There are regulations to prevent this in some countries only. Pure photosensitive epilepsy has a good prognosis. There is a role for treatment with and without antiepileptic drugs, but photosensitivity usually does not disappear spontaneously, and then typically in the third decade.

“…2. Both suffer from gastric dilatation, megacolon, and small umbilical hernia (Fairweather and O'Sullivan, 1947). They developed, simultaneously, oculogyric crises on small doses of Dartalan (thiopropazate) (Heaton-Ward et al, 1959).…”

In this preliminary report, which is part of a wider and more detailed study still in progress, I am reporting mainly the twins' mental state and associated physical abnormalities. For this purpose, I am surveying all the 2442 long-stay patients admitted during 30 years (1 September 1938-31 August 1968) to the Stoke Park Hospital Group, Bristol, which provides 1800 beds for mentally retarded patients of both sexes and of all ages. The survey's sample is shown in Tab. I.
