Milkweed is listed as a neurotoxicant causing seizures and increased CNS activity. Which statement is true?

• A. Milkweed is included in the seizures group
• B. Cannabis is included in the seizures group
• C. Isocoma is included in the seizures group
• D. Datura is included in the seizures group

Answer: (A)

Neurotoxic plants are often grouped by the main CNS syndrome they produce. When a plant is described as causing seizures and increased CNS activity, it means its toxins raise neuronal excitability enough to provoke convulsions. Milkweed fits this pattern, so it is listed in the seizures group. The other plants tend to produce different dominant syndromes: cannabis usually has CNS effects that are not primarily seizures, datura causes anticholinergic signs with delirium rather than classic seizures, and isocoma is associated with other neurologic signs such as tremors. Thus, milkweed being included in the seizures group is the true statement.
