Cyclical konzo epidemics and climate variability

Annals of Neurology, 2015
Konzo epidemics have occurred during droughts in the Democratic Republic of Congo (DR Congo) for >70 years, but also in Mozambique, Tanzania, and the Central African Republic. The illness is attributed to exposure to cyanide from cassava foods, on which the population depends almost exclusively during droughts.

KONZO, AN EPIDEMIC UPPER MOTOR NEURON DISEASE STUDIED IN TANZANIA

Brain, 1990
An epidemic of spastic paraparesis was studied in a drought-affected rural area of Tarime district in northern Tanzania. The uniform clinical findings in 39 cases, aged 4-46 yrs, indicated abrupt symmetric isolated and permanent but not progressive damage to the upper motor neurons.

[Endemic spastic paraperesis (konzo)].

Der Nervenarzt, 2003
Konzo is characterized by the abrupt onset of isolated and symmetric spastic paraparesis of the lower extremities which is permanent but nonprogressive. Epidemic outbreaks in subtropical and tropical regions are associated with drought-provoked agricultural and social crises rendering populations dependent on a diet of insufficiently processed bitter ...

New insight into the molecular etiopathogenesis of konzo: Cyanate could be a plausible neurotoxin contributing to konzo, contrary to thiocyanate

NeuroToxicology
Chronic cassava-derived cyanide poisoning is associated with the appearance of konzo, a tropical spastic paraparesis due to selective upper motor neuron damage. Whether the disease is caused by a direct action of cyanide or its metabolites is still an open question. This preliminary study assessed the neurotoxic effects of thiocyanate (SCN) and cyanate

EEG Findings in Konzo: A Spastic Para/Tetraparesis of Acute Onset

Clinical Electroencephalography, 2000
EEGs were recorded on 21 konzo subjects (median age 17 years) and 13 of their close healthy relatives (median age 41 years). Konzo subjects were clinically selected and classified according to the WHO criteria. Standard waking EEG recordings were performed according to the International 10-20 System.

Cassava cyanogens and konzo, an upper motoneuron disease found in Africa

The Lancet, 1992
Konzo is a distinct form of tropical myelopathy characterised by abrupt onset of spastic paraparesis. Epidemics in East Africa have been attributed to dietary cyanide exposure from insufficiently processed cassava but a study done in Zaire disputed such an aetiology.

Assessing diet in populations at risk for konzo and neurolathyrism

Food and Chemical Toxicology, 2011
Although both konzo and neurolathyrism are diseases associated with diet, we know surprising little about the diets of the groups at risk. The objective of this paper is to discuss methods for assessing dietary intake in populations at risk for konzo and lathyrism.

Climate regimes, El Niño-Southern oscillation and konzo epidemics

2015
Epidemics of konzo have occurred during severe droughts in parts of east, central, and southern Africa since the 1920s. Occurrence is attributed to exposure to cyanide from poorly processed cassava foods, the sole source of calories when other food crops fail.

Nyamayingi's Song: An Analysis of a Konzo Circumcision Song

Africa, 1967
Opening ParagraphTo an outsider the most striking feature of the Konzo circumcision ritual is the songs which can be heard almost constantly from the circumcision lodges. The teaching of songs is an important part of the instruction which takes place during the ritual and in many of them a special language is used which is, to a large extent ...

Danze nande-konzo (1980-2000)

2009
I Banande e i Bakonzo si considerano come appartenenti a uno stesso passato e condividono tratti essenziali della lingua e della cultura.La storia coloniale e post-coloniale li ha divisi. Attualmente risiedono gli uni nella Repubblica democratica del Congo e gli altri in Uganda. La ricerca effettuata a venti anni di distanza tra i Banande e i Bakonzo a
