Does frontal lobe dysfunction affect my lifespan or likelihood of getting Alzheimers or dementia. I have obtained epilepsy over the last couple of years and they believe the frontal lobe is linked with my epilepsy. No websites I sought out could tell me a clear answer. I know frontal lobe disorder/dysfunction is often confused with frontal lobe dementia. Can you please give me an answer asap? I am 26 and was diagnosed with epilepsy at age 21.
