19-Year-Old Diagnosed with Early-Onset โAlzheimer’s Despite No โขFamily History
A 19-year-old has been diagnosed with early-onset Alzheimer’s disease, exhibiting notable memory loss and cognitive โdecline since the age of 17. Theโฃ case is especially unusual as the patientโ hasโ no family history of Alzheimer’s or โdementia, complicatingโข classification as familial Alzheimer’s disease (FAD). This diagnosis โunderscores theโ rare, but โขdevastating, reality that Alzheimer’s is not solely a disease of aging and highlights โthe need for further research intoโข the genetic and pathological factors driving the condition in younger โคindividuals.
While Alzheimer’s is โขtypically โassociated โwith older adults, early-onset Alzheimer’s – diagnosed beforeโ age 65 -โฃ accounts for up to 10 percent of all cases. In individuals โขunder 30, a genetic mutation is often the cause. However, this patient โpresents a diagnostic challenge, โas they exhibit no โคknown genetic predisposition or history of head trauma, infection, โor other illnesses that could explain the rapidโข cognitive deterioration. Brainโ scans reveal shrinkage inโ the hippocampus, a region crucial for โmemory, andโค cerebrospinal fluid analysis โคindicates biomarkersโ consistent with common โขforms of dementia.โ
Full-scale memory and direct assessment scores are significantly lower than those of โคpeers. Previously,โข the youngest known โAlzheimer’s โฃpatient was 21 and carried โmutationsโฃ in the โฃPSEN1 gene, leading โขto theโฃ buildup of toxic proteinโ plaques in โthe brain. theโฃ 19-year-old’s โคcase is prompting further โinquiry into theโ underlying causes of early-onset Alzheimer’s โคand โขthe โpotential for previously unidentified geneticโ factors.
