Quick Read
- Histamine, often associated with allergies, may play a role in ADHD symptoms due to its impact on neurotransmitters.
- Histamine intolerance, caused by insufficient DAO enzyme activity, can lead to histamine accumulation and exacerbate ADHD symptoms.
- High histamine levels may disrupt dopamine and acetylcholine, neurotransmitters crucial for focus, motivation, memory, and learning.
- The overlap between high histamine symptoms (irritability, disrupted sleep, hyperactivity) and ADHD behaviors suggests a potential link.
- Strategies to reduce histamine levels, such as quercetin supplementation and vagus nerve stimulation, may help manage ADHD symptoms.
