Highlight
– Early-onset dementia (EOD) leads to significant productivity and income loss starting up to 15 years before formal diagnosis.
– Different EOD subtypes manifest distinct patterns and timing of income decline, with frontotemporal dementia showing earlier loss than Alzheimer disease.
– Cumulative productivity losses per patient are substantial, emphasizing the long-term socioeconomic burden of EOD.
– Enhanced early recognition and subtype-specific interventions could mitigate the financial and societal impact of EOD.
