Immune system and behavior - Introduction

This chapter and its individual sections address the connection between the immune system, stress system and behavior.

There are indications that AD(H)D could be caused by reactions of the immune system in individual cases. In principle, ADHD is likely to have other causes.

Nevertheless, the immune system has a significant impact on behavior.
Its effects are multidirectional.¹²
The immune system can be conditioned. Rats that were conditioned with a combination of sweetener and an immunosuppressor later also responded to sweetener alone with immunosuppression.³
