Sandra thinks she had her earliest epileptic seizures when she was just 4 years old. But they were no ordinary seizures. Hers gave her an intense feeling of bliss.
Blissful is not how most of us think of epilepsy. Fabienne Picard at the University Hospital Geneva, in Switzerland, says Sandra experienced a form of partial seizure – one localised to a specific region of the brain – known as an ecstatic seizure. These were immortalised in literature by the Russian novelist Fyodor Dostoevsky, who also had them.
Dostoevsky described his seizures in a letter to a friend: "I feel entirely in harmony with myself and the whole world, and this feeling is so strong and so delightful that for a few seconds of such bliss one would gladly give up 10 years of one's life, if not one's whole life."
