Lathyrism: has the scenario changed in 2013?

Area of Science:

• Neurology
• Public Health
• Nutritional Science

Background:

• Lathyrism, a neurotoxic disorder caused by consuming Lathyrus sativus (grass pea) seeds, is infrequently encountered in clinical settings globally.
• Despite its rarity, Lathyrus sativus consumption remains prevalent in certain regions, prompting investigation into the declining incidence of lathyrism.
• Socioeconomic changes, potential alterations in seed toxicity, or host defense mechanisms are hypothesized factors influencing disease prevalence.

Observation:

• A questionnaire-based study surveyed 1000 individuals in northern India to assess knowledge, attitude, and practices (KAPs) concerning Lathyrus sativus consumption.
• Four clinically suspected cases of lathyrism were thoroughly evaluated.
• The study confirmed ongoing consumption of Lathyrus sativus seeds in many Indian areas.

Findings:

• While Lathyrus sativus seeds are still consumed, a significant reduction in observed lathyrism cases was noted.
• The exact reasons for the decreased incidence of lathyrism remain unclear, despite continued exposure.

Implications:

• Further research is needed to elucidate the specific factors responsible for the reduced lathyrism rates.
• Understanding these factors could inform public health strategies related to food security and neurological health.
• Investigating potential changes in seed composition or human adaptation may be crucial.
