- Abstract:
- MRI has considerably increased our pathophysiological knowledge of age-related brain abnormalities. Brain abnormalities regularly seen on MRI of older adults are atrophy, and changes related to small vessel disease (SVD). SVD-related changes include white matter hyperintensities (WMH), lacunes, microbleeds, microinfarcts and perivascular spaces. While atrophy, WMH and lacunes are recognized as important contributors to cognitive decline and dementia, relationships are less clear for microbleeds, microinfarcts and perivascular spaces. Vascular risk factors are considered critical in the development of these changes and being potentially modifiable have become increasingly interesting to researchers and clinicians alike. Managing vascular risk early, particularly hypertension, is a key factor in slowing down the evolution of age-related brain abnormalities and decelerate their detrimental cognitive consequences. Cognition and visible brain abnormalities have a complex relationship, which reaches far beyond what we can understand using standard MRI. Remote effects of lesions and associated- as well as independent network changes likely explain much of the different cognitive trajectories observed with aging. Because of the versatility of MRI in the diagnostic of various diseases, including epilepsy, incident signs of brain aging will be encountered ever more frequently on standard MRI of older adults. To facilitate understanding and ultimately reporting these changes to patients, this review will give a brief overview of MRI findings encountered on MRI of older people. We will discuss their pathology, risk factors, and relationships with cognition. Special emphasis will be given to more recent developments, including remote effects of lesions, and effects on the structural brain network. Relationships between MRI findings in older people and epilepsy will be discussed as well.
