The case examine profiles a 19-year-old male from China experiencing gradual reminiscence decline for 2 years and reminiscence impairment (as decided by an auditory verbal studying take a look at). 

Different types of testing revealed atrophy of the bilateral hippocampus (an early signal of Alzheimer’s illness, aka AD) and hypometabolism within the bilateral temporal lobe (a symptom present in each epilepsy and dementia sufferers).

The affected person additionally displayed two main predictive biomarkers for Alzheimer’s illness—elevated focus of p-tau1812 and a decreased amyloid-β 42/40 ratio—the latter of which will increase threat of development to dementia by 70%3, in keeping with a 2019 examine from The Journal of Prevention of Alzheimer’s Illness. 

By far, probably the most attention-grabbing (and terrifying) aspect of this case examine is that no recognized gene mutations have been recognized via whole-genome sequencing. Whereas they don’t perceive the trigger, researchers have concluded this younger affected person has possible Alzheimer’s illness.
