What the evidence says 01 / RECORD
Patrick states that alcohol-induced damage increases the risk of traumatic brain injury by roughly tenfold. The tenfold figure that actually exists in the peer-reviewed literature describes a different pairing of factors: a 1995 study in Neurology (Mayeux et al., n=236) found that carrying the ApoE4 allele together with a prior history of head injury was associated with a roughly tenfold increase in the risk of developing Alzheimer's disease, compared with a twofold increase from ApoE4 alone, and no increased risk from head injury without ApoE4. A 2021 living systematic review and meta-analysis in the Journal of Neurotrauma (n=2,593) found that ApoE4 carriers have only modestly worse functional outcomes after sustaining a TBI, not tenfold worse, with an odds ratio of 1.39 for a favorable outcome in non-carriers versus carriers. Separately, ApoE4 carriers appear more vulnerable to alcohol-related neurotoxicity through impaired neuronal repair and oxidative stress, but no source located establishes that alcohol-induced brain damage itself raises the risk of sustaining a traumatic brain injury by a factor of ten. The claim as stated appears to conflate the well-documented ApoE4-plus-head-injury-history tenfold increase in Alzheimer's risk with a distinct and unsupported claim about alcohol directly raising TBI risk.
