Hello,
Thanks for choosing Doctor Spring for posting your query.
I have gone through your question in detail and I can understand what you are going through.
From the kind of history that you have stated it appears that you are having pseudo-dementia. Its not a true dementia, but occurs mostly due to an underlying depression. Its very common in depression and is obviously very distressing. It improves with medications such as escitalopram, fluoxetine, mirtazapine etc. Along with that there is an option of cognitive behavioural therapy (CBT). This therapy is taken by either a psychologist or a psychiatrist in which the therapist identifies impaired cognitions (Thoughts) and try to correct them. They are 15-20 min weekly session and there should be around 8-10 sessions to help you with your illness. Mindfulness meditation also helps.
There is a very rare possibility of TBI causing such a problem with forgetfulness. You may get an MRI done to identify if there is an element of brain damage.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
Wish you good health,
Kind regards
Dr. Srikanth Reddy M.D.
