Introduction: The loss of total brain volume (TBV) due to aging is associated with increasing ischemic white matter lesion volume (WMH) and dementia. Lower TBV may be secondary to chronic ischemia and hypoperfusion throughout the periventricular white matter rather than the burden of focal ischemia in the deep white matter. We hypothesized lower TBV would be more closely correlated with increasing periventricular white matter lesion volume (PV) rather than deep white matter lesion volume (DWMH). Methods: We enrolled 593 asymptomatic family members of probands with premature coronary artery disease (<60 years). DWMH, PV, and TBV were measured with 3Tesla MRI. Multivariate regression was completed for DWMH, PV, and TBV using volume change per age decade controlling for sex, race, diabetes, smoking currently, hypertension, obesity , and intracranial volume (ICV) for TBV, and a spline incorporated at age 54. Results: Participants were 58% women, 37% African-American, 29-74 years old. TBV/ICV was more correlated to PV than DWMH (correlation coefficients -0.26 and -0.11, p=<0.001 and 0.006). The PV was greater with older age 9%/decade until age 54 (95% CI 4-15%) and 24%/decade after age 54 (95% CI 1.6-3.2%). TBV was reduced with older age: 1.1 % smaller/decade until age 54 (95% CI -0.6 to -1.6) and 2.4% smaller/decade after (95% CI -1.6 to -3.1). For PV and TBV their age association changed significantly after age 54 (p=0.012, and 0.014). DWMH age association remained constant regardless of age. Conclusions: PV is more strongly correlated to TBV than DWMH and the age associated changes in PV and TBV were more similar to one another than DWMH. The association of increasing PV with lower TBV may help to explain the association of cognitive and motor decline with increasing PV. Future longitudinal studies are needed to verify this association.

Depression History

This study examined whether there were neuroanatomical differences evident on CT scans of individuals with dementia who differed on depression history. Neuroanatomical variables consisted of visual ratings of frontal lobe deep white matter, subcortical white matter, and subcortical gray matter hypodensities in the CT scans of 182 individuals from the Study of Dementia in Swedish Twins who were diagnosed with dementia and had information on depression history. Compared to individuals with Alzheimer's disease and no depression, individuals with Alzheimer's disease and late-onset depression (first depressive episode at age 60 or over) had a greater number of striatal hypodensities (gray matter hypodensities in the caudate nucleus and lentiform nucleus). There were no significant differences in frontal lobe deep white matter or subcortical white matter. These findings suggest that late-onset depression may be a process that is distinct from the neurodegenerative changes caused by Alzheimer's disease.

In this report, a rare case of dysembryoplastic neuroepithelial tumor (DNET) initially presented as a small white matter lesion with calcification adjacent to the lateral ventricle and extending to the frontal cortex after 7 years. This 1-year-old boy initially suffered from partial seizures. Initial CT revealed a small, low-density area surrounding a tiny calcified mass in the deep white matter of the left frontal lobe. Seven years later, his seizures had become intractable to antiepileptic agents, and MR imaging demonstrated a relatively large mass extending from the calcified lesion up to the adjacent cortical surface. He underwent surgery and the tumor was subtotally removed. Histological examination of the tumor verified it as a DNET consisting of clusters of small oligodendrocytes with floating neurons in the mucoid background. The pattern of the tumor progression in this case suggests that a DNET in the cortex originates from the subependymal germinal layer near the ventricle.
