Is there an association between infantile colic and subdural hemorrhage?

We present the hypothesis that subdural hemorrhages during childbirth might be associated with so-called three-month colic, whereby an infant cries intensively and repeatedly during its first three months. A traditional interpretation is that this infantile crying is associated with nutrition and is accordingly "a gut issue", but this is probably not the whole explanation. It has also been suggested that infantile crying can trigger a caregiver to shake the baby to make it stop crying, thereby inflicting a subdural hemorrhage. A mechanism-based argument supporting our hypothesis would be that the bilateral film-thin subdural hemorrhage associated with a high percentage of deliveries might cause meningeal irritation and in some cases also symptoms as inconsolable crying. An epidemiological argument is that infantile crying is more frequent among first-born, male and premature babies; these categories have also an increased incidence of subdural hemorrhage. Moreover, preventive programs for managing infantile crying have had no effect on the incidence of alleged shaken baby cases. As infantile crying is currently considered unexplained, it is reasonable to explore the proposed hypothesis and strategies which refute or corroborate it. We suggest that a cohort study of premature, first born and male babies with and without infantile crying are examined with brain MRI scan soon after delivery with clinically and MRI follow up during 3-6 months.
