Yes, overthinking, often a symptom of chronic stress and anxiety, significantly impacts memory by flooding the brain with cortisol, hindering focus, and disrupting the brain's ability to form and retrieve memories, leading to forgetfulness and "brain fog," though these memory issues are often temporary and not permanent damage unless chronic. High levels of the stress hormone cortisol interfere with the hippocampus, a key memory center, making it hard to concentrate on new information and recall old memories, a condition sometimes linked to increased dementia risk in repetitive negative thinking.

The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation.
