Thank you for posting your query.
Alzheimer's disease is a progressive disease characterised by memory loss
and loss of other cognitive functions. It is a clinical diagnosis (based on the assessment of brain functions by a doctor). MRI
can help in diagnosis, but is not specific for Alzheimer's disease.
Please discuss with your neurologist
regarding the diagnosis and prognosis of your mother's illness. I am sure he would help you and your family.
