Considerably elevated amyloid accumulation at 55 years in comparison with 50 years after epilepsy onset in comparison with controls. Amyloid accumulation elevated considerably extra and in broader areas within the affected person group throughout the follow-up interval in comparison with controls. Credit score: Neurology (2025).

Researchers have demonstrated that people who had childhood epilepsy have an elevated accumulation of mind amyloid later in life, doubtlessly predisposing them to late-onset mind amyloid issues, resembling Alzheimer’s illness.
The findings are printed within the journal Neurology.
The buildup of beta-amyloid protein within the mind is taken into account an early pathological mind change in Alzheimer’s illness, though the precise explanation for amyloid accumulation is unknown.
The brand new research from the College of Turku, Åbo Akademi College, and College of Wisconsin is predicated on a globally distinctive population-based cohort, collected by neurologist and now Professor Emeritus Matti Sillanpää, who nonetheless leads the cohort.
The cohort has monitored the well being and social prognosis of people who had childhood epilepsy for the reason that early Sixties and their matched controls since 1992. The follow-up is performed progressively at common intervals in collaboration with home and worldwide researchers (TACOE mission).
The current collaborative research examined the mind amyloid accumulation of those people, who had been on the verge of retirement or already retired, and their controls.
Within the earlier timepoint of the research (2013–2016), after 50 years of follow-up, researchers noticed that people with childhood epilepsy had extra amyloid plaques of their brains than the controls.
“The finding was the first of its kind globally, and it was unclear at that point whether the abnormal amyloid accumulation in the brain would continue, further predisposing these individuals to the development of memory disorders. This motivated our current study,” explains one of many key figures within the research, Professor of Neurology Juho Joutsa, from the College of Turku.
The research was performed roughly seven years after the earlier timepoint, with the contributors being 60–65 years previous. The research included 82% of the earlier contributors, a complete of 36 people with childhood-onset epilepsy, and 35 controls.
Within the affected person group, irregular amyloid accumulation was noticed in practically one-third of the contributors, whereas solely 11% of the controls confirmed this accumulation. Throughout the seven-year follow-up, the affected person group amassed extra amyloid within the mind than the controls. The affected person group additionally carried out worse in cognitive assessments in comparison with the controls, however this was not linked to the quantity of amyloid plaques.
“This suggests that the amyloid accumulation in the brain has not yet led to memory disorders,” explains Joutsa.
Distinctive cohort research allows long-term monitoring of adjustments
The distinctive cohort utilized within the research has supplied in depth details about childhood epilepsy and its prognosis over a long time.
Trendy mind imaging strategies, which now allow the research of mind amyloid pathology, had been developed a long time after the cohort was established. Joutsa, a just lately graduated doctor and now Professor of Neurology, was recruited for mind imaging analyses within the early 2010s.
The research outcomes present distinctive new details about the very long-term results of childhood epilepsy on the mind, and the follow-up continues.
“This study is also an excellent example of what can be achieved scientifically through long-term commitment of both participants and researchers, as well as collaboration across disciplines and generations of researchers,” says Joutsa.
