I am also new to site. Post covid since march er visit where labs normal. Labs by another doctor found pituitary gland and thyroid affected with levothyroxine prescribed. Neurologist brain mri covid created brain lesions and benign growth stated “it will be fine”. Referred to Speech Therapist for cognitive/memory issues and found one of suggested word search, puzzle, crossword, and sudoku for short tolerated time each day helped. I stopped as soon as any symptom started and noticed how other thinking/memory tasks during day triggered physical symptoms to plan/pace better for less down time! Hope this helped🙂
