This is very common.

The solution is the same for everyone.

When this happens, we need to STOP TO THINK.

It usually happens when there is background stimulation that distracts the brain from the line of thought. It can also be self-inflicted when we try to process too much. A common problem is called 'over attending.' Prior to whatever has trigger our symptoms, we could mentally perform without a problem in all of these situations. Now, we need to simplify our thought processes so thoughts do not collide or overwhelm us.

Word finding and using the wrong word are often the most visible symptoms since we can say a word out loud and leave people perplexed.

I have had word finding problems for 20 years. I can still get on with life. I don't pronounce the wrong word often but I frequently type the wrong word. I cannot type the word NO, It always comes out NOT. In the previous paragraph, when I typed OUT LOUD, I typed OUT LOAD. The A and U are not even close on the keyboard. This was a brain fart. They happen. They are not a sign of impending doom. We can make a correction and get on with life.

One problem I have is my sensory intake and motor control part of my brain is slower than it should be and my frontal lobe is faster than it should be. It is like a highway with some car going 70 and others going 35. They are prone to collisions. I need to slow my thinking to fit with my slower occipital lobe processing.

Anxiety makes this all worse as it speeds up processing, even when that faster processing causes crashes of various thoughts. The key is learning to slow thinking and get the brain cleared of extraneous stimuli. Some use relaxation techniques. Others have learned to just let go. Some need anti-anxiety meds to slow the brain until they can learn these other skills. SSRIs and SNRIs are better than benzos for most. Some of us use 5-HTP, L-Tryptophan, L-Theanine and such to do this without meds.

Stop to think. It works,

btw, The more we let word finding and other brain farts and confusing thoughts upset us, the more they will happen.
