Acute Symptoms	Long-Lasting Symptoms	SPECT-CT Protocol
MGA001, F, 48
13 October 2020 Throat pain, rhinorrhea, bad aches, severe fatigue and headache, but no breathing difficulties, dysgeusia, anosmia. Stays at home, cured after 12 days. Home care only	11 November 2020 Pain in both eyes, ocular pruritus, rapid ocular fatigue, noise intolerance, memory loss (forgets to pick up her daughter at school), concentration problems, remains isolated in her room, dyspnea at the slightest effort and at speech, almost continuous osteoarticular and muscular pains often with headaches, abnormal dreams, depressive feeling, fatigue, post-exertional malaise (PEM)	27 July 2021 “On the images taken, left fronto-parietal, left frontal and left thalamic hypofixation is observed. No preservation of the sensory motor cortices. The fixation in front of the cerebellum is correct. Conclusion: Scintigraphic examination compatible with a cerebral pathology of the vascular type with clearer left fronto-parietal, left frontal and left thalamic vascular disorders”.
MGA013, F, 39
3 March 2021 Cough, aching, elevated temperature, headache, 20 days in bed, loss of taste, loss of smell, severe tinnitus, 20 days in total.

Diffuse subcortical periventricular hypofixation. The basal ganglia and cerebellum show preserved and symmetrical tracer uptake. Scintigraphic image suggestive of vascular damage in the broad sense.”
