Brain atrophy is not necessarily confusion, and the duration of confusion varies from person to person and may be months or years.
Brain atrophy is usually caused by degenerative changes that occur in the brain as a person ages, and a head CT or MRI will suggest brain atrophy, but some patients have no obvious symptoms.
If brain atrophy has the symptom of confusion, it can not be ruled out due to Alzheimer’s disease and other conditions caused by the onset of the patient may be manifested as not recognizing the way home, slow reaction, etc..
The duration of confusion at the onset of the disease varies from person to person and may be months or years.
At the onset of the disease, it is recommended that the patient should go to the neurology clinic of the hospital and take reasonable treatment under the guidance of the doctor.
