Hi, I am an American Board Certified Neurologist with vast experience in diagnosing & treating all types of neurological & other medical conditions including the concerns of “Atrophy of the brain including Hippocampal area atrophy bilaterally” you have mentioned here and I am very glad to help you with your health concerns.
Please see brain atrophy including hippocampal atrophy does not automatically imply you are having neurodegenerative diseases like AD (Alzheimer’s dementia). AD is a possibility but not always because conditions like chronic bipolar disorder, or other stressful conditions too can cause atrophy of the hippocampus. I am not sure what other investigations have been done in your case, if not already done then you also need a specialized brain scan called as Amyloid PET scan which can actually provide more reliable evidence for or against this being AD. There are also CSF (Cerebrospinal fluid) tests like p-tau, t-tau & Abeta-42 peptide etc which serve as biomarkers for conditions like AD. If the above tests are not already done then you may ask your neurologist to arrange for these tests. If not already done then a detailed Neuropsychology testing will also can be of immense help in this regard. Chronic vitamin deficiencies, thyroid problems etc also can cause brain atrophy along with atrophy of hippocampal atrophy so if these conditions have not already ruled out then through appropriate blood testing these conditions need to be ruled out too.
If any of the above investigations have not been done already then please ask your doctors to arrange for these tests and this will help in finding the significance of the cerebral atrophy with bilateral hippocampal atrophy found in your brain scan.
Once again I reassure you the brain scan finding you have mentioned above does not automatically imply you are having AD (Alzheimer’s dementia), there are other possibilities too, and even bipolar disorder too can show similar findings so further testing as discussed above are needed to ascertain the precise cause of your brain scan findings and then treated appropriately.
