Perceived associations between the menstrual cycle and Attention Deficit Hyperactivity Disorder (ADHD): A qualitative interview study exploring lived experiences.

Background: The research gap regarding Attention Deficit Hyperactivity Disorder (ADHD) in people who were assigned female at birth has led to a lack of knowledge and adequate approaches in clinical practice, as well as diagnosis processes. Recent studies report potential associations between reproductive hormones and ADHD, but existing research remains scarce.

Aim: This study aims to explore the experiences of people who perceive an association between their menstrual cycle and their ADHD symptoms.

Non-genetic adaptation by collective migration.

Unlabelled: Cell populations must adjust their phenotypic composition to adapt to changing environments. One adaptation strategy is to maintain distinct phenotypic subsets within the population and to modulate their relative abundances via gene regulation. Another strategy involves genetic mutations, which can be augmented by stress-response pathways.
