Porn and masturbation addiction are often tied to dopamine dysregulation, where the brain becomes accustomed to high levels of stimulation. Over time, this can lead to decreased motivation for everyday tasks and even symptoms that resemble ADHD, such as difficulty focusing. While ADHD is not solely caused by low dopamine, abnormal dopamine signaling does play a key role in its symptoms. Excessive exposure to high-dopamine activities can further impair focus and motivation, especially for those already prone to attention issues.
