Question

an individual experiences migraine headaches and seizures. in the context of neurotransmitter functioning, which of the following most likely plays a significant role in the symptoms?
too little dopamine

too much glutamate

too little norepinephrine

too much acetylcholine

Explanation:

1. Analyze each option:

• Dopamine: Low dopamine is linked to conditions like Parkinson's or depression, not typically migraines/seizures.
• Glutamate: It's an excitatory neurotransmitter. Excess glutamate can overstimulate neurons, leading to hyperexcitability, which is associated with migraines and seizures.
• Norepinephrine: Low levels relate more to mood disorders/fatigue, not these symptoms.
• Acetylcholine: Excess is linked to muscle contractions etc., not primary for migraines/seizures.

Answer:

B. too much glutamate
