The earliest attempt at explanation was issued by Benjamin Rush in 1812, which proposed the hypothesis that a reawakening could be due to a nervous excitation caused by pain or fever, or else because of dead blood vessels, released by a leakage of water in the brain chambers. Johannes Friedreich, in 1839, proposed that the factors causing impairments may be reversed shortly before death, analogous to the reabsorption in<unk>  patients with hydrocephalus, and that high fever may be a cause of it. According to Macleod (2009) in his observations, explanative causes could not be found for the variety of cases, but it was suggested that due to the modern pharmacology in<unk>  cases, the condition may be less common today. A recent proposed mechanism include a non-tested hypothesis of neuromodulation, according to which near-death discharges of neurotransmitters and corticotropin-releasing peptides act upon preserved circuits of the medial prefrontal cortex and hippocampus, promoting memory retrieval and mental clarity.
