Cycad Plant's Hidden Danger: Neurotoxin Found in Odisha's Flora

Recent research from AIIMS Bhubaneswar has revealed the presence of BMAA, a potential neurotoxin, in Cycad plants found in Odisha. This discovery is alarming as local communities consume Cycad-based foods, raising concerns about the risk of neurological diseases. An international workshop highlighted the serious health implications associated with these ancient plants, which have existed for over 300 million years. Experts are now focused on understanding the health risks and developing strategies to mitigate them. The findings underscore the need for increased awareness and research into the effects of Cycad consumption on local populations.

Research Uncovers Neurotoxin in Cycad Plants

Bhubaneswar: Researchers from various medical institutions have detected BMAA, a possible neurotoxin, in multiple species of the Cycad plant located in Odisha's forests, as reported by AIIMS Bhubaneswar.

This alarming discovery is particularly concerning since some local communities consume products derived from the Cycad plant, such as 'pitha', as part of their dietary practices and cultural rituals.

The research conducted by AIIMS Bhubaneswar aims to determine if the consumption of Cycad-based foods poses a direct risk for neurological disorders.

"The critical question remains whether the intake of Cycad plant-based foods correlates with a higher occurrence of neurological diseases. AIIMS Bhubaneswar has commenced research to explore this issue," the institution stated on Tuesday.

Experts have engaged with local villagers, patients, and healthcare providers to assess the potential neurological and health issues linked to the consumption of Cycad seeds.

Recently, a prominent group of national and international scientists and medical professionals convened for an international workshop titled “Cycad-Related Neurological Disorders: A Multi-Dimensional Approach to Its Remediation.”

This event was co-hosted by the Department of Neurology at AIIMS Bhubaneswar and North-Eastern Hill University (NEHU) in Shillong.

The workshop underscored the significant health hazards associated with the Cycad plant, which has existed alongside dinosaurs for over 300 million years.

"Cycad species, often used as ornamental plants today, contain powerful toxins such as Cycacin, BMAA (ß-N-methylamino-L-alanine), and MAM (methylazoxymethanol)," the statement noted.

These toxins have been linked to severe neurodegenerative diseases like Parkinsonism, motor neuron disease, and dementia in various regions worldwide, particularly in Guam and Japan, where the plant has been traditionally consumed.

The workshop concluded with a pledge to develop a comprehensive strategy for advancing research, raising community awareness, and promoting interdisciplinary collaboration to understand and reduce the health risks associated with Cycad consumption.
