Answer this question to the best of your ability:
What are the shared underlying mechanisms between these two conditions?
There's no single cause for either depression or ADHD, but several factors can contribute to both. One such common factor is neurobiological. Studies have found that there might be alterations in certain brain regions and neurotransmitters, like serotonin, dopamine, and norepinephrine, which play a crucial role in mood regulation and executive functioning. These alterations can increase the risk for developing both depression and ADHD.
