In simple words, diffuse cerebral atrophy
means generalized shrinkage of the brain tissue, which is detected in CTscan or MRI of brain. There are many causes for the atrophy like age related and alzheimer's dementia
. Usually, there will be other problems like forgetfulness and difficulty in carrying out daily activities. Since your mother is aged only 50 (age related atrophy is unlikely) and has complaints like difficulty in walking and talking, a detailed evaluation is necessary to rule out brain damage
due to minor strokes (hypertension
melitus are risk factors).
Unfortunately, if the problems are indeed due to atrophy, chances of recovery are less. The priority will be to prevent further deterioraion.
