Lately I have noticed that my brain function (thinking, speaking, reading out loud). This causes me to stumble on my words and not form complete thoughts while speaking to others. My mind seems to jump from topic to topic as well (similar to a short attention span).
I am thinking this has something to do with a reduction in brain function (somehow?) - What information can you give me on brain function and how it can be restricted due to lifestyle changes, social interaction, etc.
