Is there an association between infantile colic and subdural hemorrhage?

Area of Science:

• Neurology
• Pediatrics
• Neonatology

Background:

• Infantile crying, or three-month colic, is often attributed to digestive issues but may have other causes.
• The shaken baby syndrome hypothesis suggests crying can lead to inflicted subdural hemorrhages.
• Existing preventive programs for infant crying have not reduced alleged shaken baby case incidence.

Purpose of the Study:

• To propose and explore the hypothesis that subdural hemorrhages occurring during childbirth are associated with unexplained infantile crying.
• To investigate a potential mechanism where minor subdural hemorrhages cause meningeal irritation and inconsolable crying.
• To examine epidemiological links between infantile crying and subdural hemorrhage risk factors.

Main Methods:

• Propose a mechanism-based argument: bilateral, thin subdural hemorrhages from delivery may cause meningeal irritation and crying.
• Present epidemiological evidence: first-born, male, and premature infants are at higher risk for both crying and subdural hemorrhage.
• Suggest a cohort study using brain MRI in premature, first-born, and male infants with and without crying, with 3-6 month follow-up.

Main Results:

• The hypothesis posits that subdural hemorrhages, common in deliveries, could be a source of infantile crying.
• Epidemiological data suggests shared risk factors between infantile crying and subdural hemorrhage.
• Preventive strategies for crying have not impacted alleged shaken baby cases, suggesting alternative explanations.

Conclusions:

• The proposed hypothesis offers a potential explanation for unexplained infantile crying.
• Further research, including cohort studies with brain MRI, is warranted to confirm or refute this association.
• This research could lead to new diagnostic and management strategies for infantile crying and subdural hemorrhages.
