Distinct fiber-specific white matter reductions pattern in early- and late-onset Alzheimer’s disease

Early and late onset Alzheimer's disease patients have distinct patterns of white matter damage.

We investigated patterns of white matter (WM) loss in 18 early onset (EO) and 24 late onset (LO) Alzheimer's disease (AD) patients compared with 42 healthy controls (HC), and explored relationships of WM atrophy and apolipoprotein E (ApoE) genotype. Subjects underwent magnetic resonance imaging (MRI). Patterns of WM were assessed using voxel-based morphometry. Compared with healthy controls, LO...

99mTc-TRODAT-1 SPECT Imaging in Early and Late Onset Parkinson’s Disease

Objective(s): 99mTc-TRODAT-1, which binds to the dopamine transporter, could be used to image the dopaminergic system in diagnosis of Parkinson’s disease (PD). PD can be classified into two groups: late onset Parkinson’s disease (LOPD) and early onset Parkinson’s disease (EOPD). In this study we tried to determine the TRODAT SPECT findings in EOPD as compared to LOPD.Methods: Fifteen patients w...

Genetic contribution to white matter hyperintensity burden in early- and late-onset ischemic stroke patients

Longitudinal white matter change in frontotemporal dementia subtypes and sporadic late onset Alzheimer's disease

BACKGROUND Degradation of white matter microstructure has been demonstrated in frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD). In preparation for clinical trials, ongoing studies are investigating the utility of longitudinal brain imaging for quantification of disease progression. To date only one study has examined sample size calculations based on longitudinal changes i...

Early white matter changes in Wilson disease.

We describe a 12 years old male who presented with one year history of cognitive decline with extrapyramidal features. Wilson disease was diagnosed on basis of biochemical studies and MRI. MRI showed increased signal intensity on T2 weighted images in basal ganglia and supratentorial with infratentorial gray and white matter. Our patient developed white matter changes early in course of disease.
