Why Mental Illnesses Co-occur: A Neuroscientist's Explanation
Educational Video · Short-form Video
About this work
A neuroscientist explains why certain mental illnesses often appear together, such as Autism, ADHD, Depression, and Bipolar Disorder. The video highlights the role of inflammation, the corticolimbic pathway, dopamine activity in the frontal lobe, and how stress and trauma can impact these functions, leading to shared symptoms or misdiagnoses. The format includes direct-to-camera explanations, on-screen text, and brain illustrations.

Why mental illnesses show up together I'm a Neuroscientist I'm gonna explain mental illnesses together Autism ADHD Depression Dysthymia Borderline Personality Disorder Schizophrenia etc. what's the all these mental illnesses have in common? dopamine activity in the frontal lobe frontal lobe is shut off 1. Stress and trauma cause oxidation in your body has to reallocate resources to fight the problem, 2. Inflammation is your body fighting oxidation Cerebral Cortex Pathway MESOCORTICOLIMBIC PROJECTION (purple) Prefrontal cortex Nucleus accumbens Ventral tegmental area (VTA) Striatum Substantia nigra 3. Inflammation shuts this down its job is to send dopamine from the Midbrain to the Cortex this pathway is important for Frontal Cortex Attention Focus Social Behavior Emotional Reactivity Connection Motivation Emotional Regulation Impulse Control Conscious Awareness Pleasure so the reason why things like autism and ADHD and depression are often seen together and even misdiagnosed is because they share a common biological pathway. Unfortunately your brain can shut down the functionality of this pathway for decades at a time if the core problem isn't directly addressed although it's not seen as evolutionarily important it's the difference between being alive, and truly living Tune in for more
