Editing Retrograde amnesia (section)

=== Infections ===
Infections that pass the [[blood–brain barrier]] can cause brain damage ([[encephalitis]]), sometimes resulting in the onset of RA. In the case of patient 'SS', the infection led to focal or isolated retrograde amnesia where there was an absence of or limited AA. Brain scans show abnormalities in the bilateral medial temporal lobes, including two thirds of the hippocampal formation and the posterior part of the amygdala.<ref name="Fujiietal">{{cite journal | vauthors = Fujii T, Yamadori A, Endo K, Suzuki K, Fukatsu R | title = Disproportionate retrograde amnesia in a patient with herpes simplex encephalitis | journal = Cortex; A Journal Devoted to the Study of the Nervous System and Behavior | volume = 35 | issue = 5 | pages = 599–614 | date = December 1999 | pmid = 10656630 | doi = 10.1016/S0010-9452(08)70822-0 | s2cid = 4480119 }}</ref>
