Alzheimer's disease with late onset [G30.1] / Dementia in other diseases classified elsewhere without behavioral disturbance [F02.80], Reason for Study: ^Reason: cognitive decline suggestive of Alzheimer's disease History: Memory decline There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Multifocal scattered FLAIR/T2 high signal intensity on periventricular white matter are nonspecific, most likely represent nonspecific small vessel disease.Diffuse but mild atrophy of brain is seen with prominent Sylvian fissures and CSF spaces on bifrontal lobes.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No evidence of acute ischemic or hemorrhagic lesion.Prominent CSF spaces especially at bilateral sylvian fissures and bilateral frontal area indicating mild brain atrophy as described above.
