Why Do People with ADHD Traits Experience Depression and Lower Quality of Life? Study Sheds Light
A new study published in BMJ Mental Health found that insomnia, or sleep disturbances, that happen due to ADHD's impulsivity could be the reason why adults with ADHD symptoms experience a reduced quality of life. The research provides compelling evidence that heightened cognitive activity before sleep may be a key factor in the poor sleep quality.
ADHD, a neurodevelopmental disorder affecting approximately 2.5% of adults, is often accompanied by chronic sleep difficulties. Up to 90% of people with ADHD report problems such as insomnia and excessive daytime sleepiness. While the link between ADHD and sleep issues has been well documented, the mechanisms behind this connection have remained largely unclear.
To explore the potential mediating role of pre-sleep arousal, researchers collected data from two independent groups—104 online participants and 96 in-person respondents recruited a year later to replicate the initial findings. Participants completed self-report questionnaires that measured ADHD traits, levels of pre-sleep arousal, and overall sleep quality. The study adhered to strict ethical protocols, with all participants providing informed consent and the freedom to withdraw at any time.
