BACKGROUND: Konzo is an irreversible upper-motor neuron disorder affecting
children dependent on bitter cassava for food. The neurocognitive ability of
children with konzo over time has yet to be fully documented. METHODS: We did a
longitudinal study in a konzo outbreak zone continuously affected by konzo since
1990, in the district of Kahemba, southern Bandundu Province, Congo. We enrolled
children with a record of neurological diagnosis of konzo in Kahemba town. For
all study children with konzo enrolled in the final sample for the baseline
assessment, a neurological exam was done by neurologists to confirm konzo
diagnosis using the 1996 WHO criteria at 2 years and 4 years. In the initial
baseline sample for each child with konzo, we attempted to get consent from a
comparison child without konzo (1996 WHO criteria) within 2 years of age, from a
neighbouring household who met inclusion criteria. The neuropsychological
assessments were the Kaufman Assessment Battery for Children, second edition
(KABC-II), and the Bruininks-Oseretsky Test of Motor Proficiency, second edition
(BOT-2). FINDINGS: Data collection occurred between Oct 12, 2011, and Aug 14,
2015, in the town of Kahemba. 123 children from the Congo with konzo and 87
presumably healthy children without konzo from neighbouring households were
enrolled. The planned assessments were completed by 76 children with konzo and 82
children without konzo at 2-year follow-up, and by 55 children with konzo and 33
children without konzo at 4-year follow-up. Boys with konzo did worse than those
without konzo on the KABC-II Learning (p=0·0424) and on the Mental Processing
Index (MPI; p=0·0111) assessments at 2-year follow-up, but girls did not. These
differences observed in boys might have been caused by stunting. At 4-year
follow-up, the difference in KABC-II MPI score between boys or girls with or
without konzo was not significant. Both boys and girls with konzo had lower
scores on BOT-2 than children without konzo at both follow-up times (p<0·0001).
These differences were not attenuated when controlling for physical growth. Boys
with and without konzo declined on BOT-2 fine motor proficiency at 2-year
follow-up (boys with konzo p=0·0076; boys without konzo p=0·0224) and KABC-II MPI
performance at 2-year follow-up and 4-year follow-up (2 years: boys with konzo
p<0·0001, boys without konzo p=0·0213; 4 years: boys with konzo p=0·0256, boys
without konzo p=0·10), but that was not the case for the girls with scores
remaining stable regardless of konzo status. For boys, increases in urinary
thiocyanate concentration was significantly associated with reductions in BOT-2
motor proficiency (p=0·0321), but was not significantly associated in girls and
urinary thiocyanate concentration was not associated with KABC-II MPI score for
either boys or girls. INTERPRETATION: Motor and cognitive performance continues
to be significantly impaired in boys with konzo at 2-year follow-up compared with
boys without konzo. Because these impairments are associated in part with
exposure to poorly processed cassava as measured by urinary thiocyanate,
interventions are urgently needed to ensure improved processing of cassava to
detoxify this food source. FUNDING: US National Institutes of Health.
