Children who survive severe malaria face lasting cognitive damage that can cut their lifelong earnings by up to 15 percent, according to a 15-year study tracking 600 Ugandan children.
How cerebral malaria and severe anaemia impair brain development
The research presented at an international congress found that cerebral malaria and severe malaria-related anaemia cause the most significant long-term cognitive deficits, with affected children showing measurable impairments years after recovery.
One year after infection, 12.1 percent of children with severe anaemia and 10.6 percent with cerebral malaria exhibited cognitive difficulties, compared to just 1.9 percent in a healthy control group.
Why anaemia poses a hidden threat to neurological health
Doctors were surprised that children with severe anaemia often showed no immediate neurological symptoms yet still developed cognitive impairments over time, indicating delayed brain damage from the infection.
The parasite Plasmodium falciparum damages the blood-brain barrier, triggers neuroinflammation, and causes infected red blood cells to cling to brain capillaries, leading to oxygen deprivation and disrupted energy supply to nerve cells.
What the economic consequences look like for affected regions
