Australia recently approved Lecanemab for early-stage Alzheimer’s disease. Dementia causes progressive memory and thinking problems and is now Australia’s leading cause of death.

It aims to slow disease progression by tackling the cause of Alzheimer’s, not just symptoms. The drug works by using antibodies to mark amyloid for removal by brain immune cells, preventing toxicity to brain cells.
