Compare post encephalitis Parkinson's living with sepsis

Post-encephalitic Parkinsonism is a fixed, slow-moving brain injury. Sepsis is an acute body-wide assault with a long, ugly tail. They are not the same kind of illness.

The retrieval is thin on post-encephalitic Parkinsonism specifically. One Egyptian door-to-door survey found just one post-encephalitic case among 44 people with parkinsonism, and that survey used EEG to screen for it [1]. The only detailed modern picture comes from two elderly women who developed parkinsonism after SARS-CoV-2 encephalitis: one was still at a modified Rankin score of 4 (moderately severe disability) nine months out [2], and the other died of infected bedsores and aspiration pneumonia within a month of discharge [2]. That is a small, grim sample, not a prognosis.

Sepsis survivors face a different pattern. In a German claims cohort, 12-month mortality after respiratory sepsis was about 27 in 100, versus about 15 in 100 after SARS-CoV-2 sepsis [4]. Cognitive diagnoses hit roughly a third of respiratory sepsis survivors [4]. A separate review found new physical limitations averaging 1.57 per patient, cognitive impairment rising from about 6 in 100 before hospitalization to about 17 in 100 after, and 40 in 100 readmitted within 90 days [3].

The honest gap: no retrieved study directly compares these two groups head to head. The parkinsonism records are case reports and prevalence counts [1][2]; the sepsis records are cohorts and reviews [3][4]. You are comparing two different evidence types.

My call: sepsis survivors carry a heavier measured long-term mortality and cognitive burden in these records, but the post-encephalitic parkinsonism evidence is too thin to rank against it fairly. Confidence: low, because the direct comparison was never made in what surfaced here.
