My mother (66 years) has hypertension and past history of stroke 2 yrs back. She met with a Road accident 20 days ago and besides fracture was fine brainwise. She was able to read write and acted normally upto 2 weeks after accident. Since last two days She is saying she is forgetting everything, She is not able to read sentences or compose sentences. She only remembers and recognises people/events very close. She is able to count and add small numbers but not subtract. She can count 1 to 10. I referred with neurologist and neurosurgeon who say they did not find anything wrong in CT scan and blood test, suggested to see a psychiatrist.
Though I will refer a phychiatrist as advised, I am not really able to buy this theory completely. Also, I notice that since she reported memory loss first time yesterday, she is much better today. Can somebody please suggest me options, should I wait to see improvement in passing days, or should I refer the case with another neurophysician. I am located in Bombay, India. Please Help!.
