In most cases of epilepsy it is not possible to reach an aetiological diagnosis. Recent research points to a pre-perinatal disruption of the neurodevelopment as being the cause of at least some of these epilepsies of unknown aetiology. The object of this study was to corroborate this hypothesis from an ...

Compared to the general population, one consistent finding in schizophrenia research is a significant surplus of schizophrenic births in the winter/spring months. There is little evidence that this is attributed to statistical artefacts. The "harmful effects' hypothesis offers the most plausible explanation for this phenomenon. Exogenous harmful effects, predominant during ...
